Revision History ---------------- XV 3.10a bug-fix release 12/29/94 ---------------------------------- Bug Fix: Problems loading JPEG files in 8-bit mode on some systems. (Rick Richardson (rick@digibd.com)) (Chad R. Larson (chad@anasazi.com)) Bug Fix: Added '-pkludge' command line option and 'popupKludge' boolean resource. If true, selects the 'old-style' pop-up window positioning code. The various popup windows should appear with the Ok button (or whatever) centered around the cursor. If the windows routinely pop up slightly off-center from the cursor, try turning this on. Bug Fix: '3' and 'Q' characters in the Text Annotation character set were boogered up... (Sidik Isani (si@acpub.duke.edu)) Bug Fix: '-iconic' option wasn't working. (David Pesetsky (iedsp@agt.gmeds.com)) Bug Fix: Didn't properly read greyscale RLE files. (Robert Cunningham (rkc@xn.ll.mit.edu)) Bug Fix: 'AutoCrop' on 24-bit images could produce 0x0 images. A problem! (Leon Shaner (leon@mtu.edu)) Bug Fix: GIF reader would blow up if there were multiple comments. (Markus Gyger (mgyger@itr.ch)) Bug Fix: Behavior under virtual window managers may be improved. (steveg@pa.dec.com) Enhancement: Text in 'temperature gauge' (during slow operations) is now XOR'd on, so it isn't obscured by the filled area of the gauge. (Jerry Whelan (jerryw@bnl.gov)) Enhancement: man page for vdcomp written (James Ralston Crawford (qralston+@pitt.edu)) Enhancement: PCX code can now read 24-bit PCX files. (Dave Cohrs (cohrs@legato.com)) Portability: Patch for Linux (David Hankins (dhankins@oz.net)) Portability: Patches for ISC 4.0 Interactive/SunSoft Unix (Jack Bailey (jjb@jagware.bcc.com)) Portability: Compiler noise (from Sun's Professional C compiler) cleaned up. (John Fritz (jfritz@bpo-ess.ceco.com)) Portability: Many nits picked by Pyramid compiler (Chad R. Larson (chad@anasazi.com)) Portability: Some malloc's in xvfits.c needed casting. (Bill Silvert (sysop@biome.bio.ns.ca)) Portability: Further VMS problems solved. (Rick Dyson (dyson@sunfish.physics.uiowa.edu)) Portability: select() on HP-UX 9.x expects (int *) instead of (fd_set *) (Richard Allen (ra@os.is)) Portability: Removed 'const' from second parameter in decl. for decode_run() in tif_fax3.c. (Glenn Spargo (gspargo@ctron.com)) Portability: Added 'fcntl.h' to xv.h, as some systems may not have O_RDONLY declared elsewhere. (Mitchell Blank (blankm@cae.wisc.edu)) Portability: Font selection strings in xv.c didn't have enough '*'s in them. Would fail on some X servers. (Rick Richardson (rick@digibd.com)) Second XV 3.10 Public Release 12/22/94 ---------------------------------------- Bug Fix: Make_xv.com in vms directory wouldn't build xvxpm.c or xvfits.c (and thus, XV!) (Rick Dyson (dyson@sunfish.Physics.UIowa.Edu)) Initial XV 3.10 Public Release 12/21/94 ---------------------------------------- Bug Fix: Greyscale downsampling bug in JPEG code fixed. (Tom Lane (tgl@sss.pgh.pa.us)) Enhancement: Made Grab command trap 'BadMatch' errors and display an appropriate error message (rather than exiting with a fatal error). (Eric Demerling (x450b05@rdsrv2.goodyear.com)) Enhancement: Cleaned up/reorganized Makefile (Tom Lane (tgl@sss.pgh.pa.us)) Portability: BSDI doesn't have malloc.h. Fixed xv.h and vdcomp.c (Chris Ross (cross@eng.umd.edu)) Bug Fix: Additional VMS schnauzer fixes. (Rick Dyson (dyson@sunfish.Physics.UIowa.Edu)) Second XV 3.10 Beta Release ---------------------------- Portability: xvxpm.c module rewritten to include its own hash-table routines, as 'hsearch()' is not available on all systems. (Chris Ross (cross@eng.umd.edu)) Bug Fix: Big stupid mistake in xvtiff.c module. Too embarrassing to mention. (Michael Weller (eowmob@exp-math.uni-essen.de)) Bug Fix: failing to store clipboard contents in an X property was (incorrectly) exiting the program as a fatal error, rather than falling back to using a '.xvclip' file in your home directory. (Eric Demerling (x450b05@rdsrv2.goodyear.com)) Docs: Mentioned 'FITS' format, removed claim that rotate 90-degree commands will rotate selected area, added additional credits. Bug Fix: Cleaned up xvxpm.c - potential for infinite loops on broken images. Also, now handles 'None' better, and mentions when it can't parse colorspecs. Bug Fix: When viewing large images, a rotate may not have properly redrawn the image. Also, it could lose the proper aspect ratio. (Michael Weller (eowmob@exp-math.uni-essen.de)) Bug Fix: 'Expansion' and 'Resolution' fields in xv info window weren't getting updated when image was rotated. Bug Fix: If you were in Perfect or OwnCmap color modes, and switched to a root display mode, it didn't (correctly) switch to Normal colors. (Michael Weller (eowmob@exp-math.uni-essen.de)) Added Feature: XV can now read and write greyscale FITS images (David Robinson (drtr@mail.ast.cam.ac.uk)) Enhancement: XV can now read old Windows and OS/2 BMP files (Eric Dumas (dumas@daubasse.emi.u-bordeaux.fr)) Portability: now uses the Dec 8 re-release of IJG jpeg software (ver. 5a) (Tom Lane (tgl@sss.pgh.pa.us)) Portability: need to include on aix systems ('_AIX') (Eric Demerling (x450b05@rdsrv2.goodyear.com)) Portability: NetBSD objects to 'extern char *sys_errlist[];' (Chris Ross (cross@eng.umd.edu)) Portability: CBSIZE (in xvbutt.c) is defined on some systems in param.h. Changed to XVCBSIZE. (Chris Ross (cross@eng.umd.edu)) Portability: 'Makefile' in TIFF directory assumed 'ar' lived in /bin. This isn't necessarily so. It'll now just search the path. (Michael Weller (eowmob@exp-math.uni-essen.de)) Bug Fix: recursive update on VMS didn't work right (Rick Dyson (dyson@sunfish.physics.uiowa.edu)) Initial XV 3.10 Beta Release ---------------------------- Added Feature: XV now comes with 'xvpictoppm' program, which reads XV thumbnail files and converts them to standard PPM format. Added Feature: XV can now read the XWD format. Whether or not this will still be an issue, given the whizzo new 'Grab' command, I don't know. XV does *not* write XWD files, as XWD is not a format to be encouraged. (Markus Baur (mbaur@ira.uka.de)) Bug Fix: 'xv -poll -root ' would thrash wildly if the file didn't exist, or wasn't loadable. Now behaves better. Added Feature: 'Recursive Update' command in visual schnauzer. Does an 'update' command in the current directory, and recursively down into all subdirectories. Keyboard Equivalent: ^e Bug Fix: Potential problem when allocating colors for std colormap. (Yasuhiro Imoto (tomo@sonytek.co.jp)) Bug Fix: Cropping a large area while zoomed in could result in enormous, potentially off-screen images. A bad thing. Added Feature: Added a 'Select Files' command in the visual schnauzer, which lets you select files by name. The wildcard character '*' (which matches any arbitrary char sequence) is supported. This gives you an easy way to select all the JPEG files ('*.jpg'), for example. Keyboard Equiv: ^f Bug Fix: Added support for 15-bit-per-pixel displays, and probably fixed support for 15/16-bit LSBFirst displays. At least on 80x86-based machines, which is where nearly all 15/16-bit displays have to be. (Michael Weller (eowmob@exp-math.uni-essen.de)) Bug Fix: Somewhere along the line, the file name list (in the controls window) was getting redrawn at least one time too many, when you loaded files from the schnauzer. Added Feature: Added a 'despeckle' algorithm (median filter). (Colin Plumb (colin@nyx10.cs.du.edu)) Added Feature: XV now can read and write the XPM format. It can read XPM images with any number of colors, though it only writes XPM images with a maximum of 256 colors. (If your image has more than 256 colors, it is automatically quantized.) While the XPM format lets you do arbitrary-depth images, it's not really well suited for images with more than a small number of colors, so the 256 color limitation shouldn't be a big problem. (Chris P. Ross (cross@eng.umd.edu)) Added Feature: Added a 'Origin' button the the 'Save Postscript...' window. Positions the image aligned at the bottom-left corner of the page, which is the origin (0,0) in the Postscript world. May make certain desktop-publishing operations easier if you're using XV to generate EPS files for incorporation into page-layout software. (Michael Lipscomb (lipscomb@vision1.engr.utk.edu)) Enhancement: Added 'xv.pspaper', 'xv.psorient', and 'xv.psres' options to set default behavior in the 'Save Postscript..." window. pspaper sets the default paper type, and can be any of the following: 8.5x11 A4 B5 A3 8.5x14 11x17 4x5 35mm psorient sets the default paper orientation, can can be either 'portrait' or 'landscape' psres sets the default resolution (dpi) and can be an integer between 10 and 720, though not all values are attainable, as the resolution is controlled by the 'scale' dials, which must take on integral values. All the common resolutions are available, however (72dpi, 75dpi, 100dpi, 300dpi, 600dpi, etc.) Added Feature: Added a '-nodecor' option (and boolean 'xv.nodecor' resource) that lets you turn off the window 'decorations' (title bar, menu box, minimize and maximize buttons) on the XV image window, in MWM. When these things are on (by default), the prevent the image window from being made smaller than some MWM-specified minimum width, which can be a real pain when working with tiny (< 100 pixels wide) images. Turning this option on disables these decorations, and lets the image window be any size whatsoever. (This only works for MWM. TWM doesn't have this problem, and OLWM doesn't appear capable of doing this on the fly, on a per-window basis. For OLWM, use the 'owlm.MinimalDecor: xv' resource. Note this affects *all* xv windows.) Bug Fix: Input focus wasn't working out correctly under OLWM. Bug Fix: "-rotate" command line option was only applied to the first image loaded. (Osama (neiroukh@vision1.engr.utk.edu)) Enhancement: The 'slow' 24->8 algorithm now uses code derived from the IJG jpeg distribution, which is a considerably better implementation of the median-cut algorithm than XV was using before. Enhancement: Version 5 of the jpeg library (which XV now uses) supports a quick image subsampling 'thing' which XV now uses when generating Visual Schnauzer icons. Practical upshot: creating icons from jpeg files is now many times faster. Bug Fix: 'xv -hist -expand ' would crash. Doesn't do that any more. (Ulf Cahn von Seelen (cahn@grip.cis.upenn.edu)) Enhancment: XV can now read 16-bit per pixel 'raw' PGM and PPM files. (David A. Clunie (dclunie@flash.us.com)) Enhancment: In the Schnauzer, if you hold 'shift' while hitting the spacebar, it will select (and load) the next file, while keeping the previous file selected. This lets you (somewhat more easily) build groups of files to be moved or deleted, as you can just hold shift, and space your way through all the files. Shift click to de-select files that should be skipped. Added Feature: Added an 'annotate' command that lets you put text on an image. Keyboard Equivalent: 'A'. To use it, select a drawing color using the 'dropper' (middle click on image), and press the 'A' button. Enter a string and hit Ok (or return). If there is a current selection, the text will be scaled to fit the selection. Otherwise, a selection box the size of the text will be created in the middle of the image window. In this case, position and resize the selection, as you see fit, and issue a 'Paste' command (meta-v) to place the text on the image. Note: if you want to change the color of the text, choose a new color and do the annotate command again. It's somewhat awkward, but it's time for a new release. It'll probably get polished in the next release... Change: 'AutoCrop' keyboard equivalent is now 'C' instead of 'A'. Added Feature: Added 'smudging'. Shift-right click (and drag) on the image (it's best if you zoom in first), and you can do a localized blur around the cursor. Note that this only works on 24-bit images. If the current image is a 8 bits deep, it will be converted into a 24-bit image first, automagically. Added Feature: Added rudimentary image painting. You can now paint arbitrary curves (or straight lines) by doing a shift-middle click (and drag) on the image window. The pen will draw in whatever the last color picked up by the 'dropper' (middle click on image) was, (just like the 'clear' command). Shift-middle will draw curves. Shift-ctrl-middle will draw a connected series of line segments. Release and press ctrl to draw unconnected line segments. Note: there's no direct way to paint in any arbitrary color. The paint color must exist in the image *first*. One way of adding colors to an image is via the 'Pad' command. Try padding with 'bggen', using the 'Color Assortment' default to get a reasonable collection of different colors added to the image. Later you can pad the image back to its original size to get rid of the colorful borders. BE SURE to switch to 24-bit first... Change: Changed 'Standard Colormap' (used whenever viewing 24-bit images on a non-TrueColor/DirectColor display) from a 6*6*6 colormap to a 4*8*4 colormap. It uses fewer colors (128 instead of 216), and produces better looking images (as the 2 extra green values more than make up for the 2 fewer red and blue values). It also looks somewhat better when you use '-stdcmap' with '+vsperfect' (ie, have the schnauzer share the stdcmap), as the 4*8*4 maps closer to the 8*8*4 used internally by the schnauzer than the 6*6*6 did. Enhancement: Added a 'trashcan' to the Visual Schnauzer. You can now (also) delete files by dragging them to a trashcan. You'll be asked for confirmation, the same as the 'Delete' command. Change: 'unknown' files in the browser are now shown as 'plain' files. Change: Moved a couple of keyboard equivs. 'p' now pops up the 'go to page' dialog (when viewing a multi-page document) (was ^P). ^P is the keyboard equiv for the Print command. Meta-a is the keyboard equiv for the Apply command (in the color editor). (was ^P) Added Feature: Added a 'Print' command. ("Finally!", I hear many of you saying.) Keyboard equiv '^P'. Quicker and easier to use than the previous method (ie, saving PostScript to "| lpr"), even though that's how it still does the trick. Much more intuitive for Joe User, who wouldn't know a pipe if you hit him over the head with one... Enhancement: When tracking pixel values (dragging the middle button around on the image window), it now displays the distance of the current point from where you originally clicked in a pair of square brackets (ie, '[ -5, 37]') at the end of the line. Handy for measuring image features. Bug Fix: XV now supports both the 'cut buffer' and the 'selection' methods of doing text cut-and-paste. (ie, the 'CutRes' command, and tracking pixel values). Prior to this, pasting either of those things into an xterm may or may not have worked, depending on whether another xterm had a current selection. Bug Fix: (Sort of). Now that XV tries to grab a good visual, rather than just using the default, it may now pick a 24-bit visual on machines where the root window can only hold an 8-bit image. In these cases, it will disable the 'root' choices, unless you start XV with the '-root' option, in which case it will choose a root-compatible visual. Not optimal, but better than it was... Enhancement: XV now displays a 'working' icon when the image window (or the control window, if there is no image window) is iconified and XV is in the middle of a long operation (smoothing, loading a jpeg, running an algorithm, etc.) The icon changes back to the normal icon when the operation completes. (Idea: Bob Boag ) Enhancement: It now displays what mode (8-bit or 24-bit) it's currently in, in the controls window and the info window. Added Feature: Changed PadImage command to allow 'blended padding' (ie, not-fully-opaque), in several modes (RGB, Hue, Sat., Int.,). In the HSV modes, it only pastes/blends the specified component of the background fill. You can get a variety of weird effects. Ferinstance, take a grayscale pic, and pad it with a bggen'd RGB rainbow, using Hue mode and Opaque=0. Added Feature: Added a 'Smear' algorithm. Keyboard equiv 'meta-S'. Added Feature: Added a 'Sharpen' algorithm. Keyboard equiv 'meta-s'. Bug Fix: Substantially improved performance on DirectColor displays. (Read: 'it works at all') It's been tested on a 24-bit DirectColor, and an 8-bit DirectColor visual. It works on those, at least. (TrueColor is still the recommended visual type, though since XV now sniffs around for a TrueColor visual, it'll probably Do The Right Thing by default. Certainly that's the design.) Added Feature: Added a 'PadImage' command (keyboard equiv: 'P'). Lets you make an image larger *without* rescaling it, by creating a new image of the specified size and pasting the original image onto the center of the new image. Currently, the new background can either be a solid color, the result of running 'bggen', or an image file in any of the supported (loadable) image formats. The resulting image will be the same 8/24 bit mode as the original image. As such, it's generally recommended that you switch to 24-bit mode before doing the Pad command, for best results. Also, there are associated X resources: 'xv.pad.TYPE.val[0-9]' and 'xv.pad.TYPE.name[0-9]', that let you specify the values and names of additional entries in the 'Default' menu in the Pad dialog box. 'TYPE' can be either 'color', 'bggen', or 'load', depending on which 'method' of background generation you're using. Added Feature: In 'bggen', you can now specify colornames as with other X programs (ie, by name ('red'), or by value ('#ff00ff')). Note that the '#' character is treated specially in some shells, and probably need to be escaped with a '\' (or wrap single-quotes around the whole value) Added Feature: In 'bggen', added '-G geom' option to specify a 'repeat' geometry. If given, the program generates its gradient into a small (-G geom) image, which is 'center-tiled' into the main (-g geom) image. Change: In 'bggen', change '-s' option to '-h'. Screw backward compatibility, it makes more sense. Enhancement: Massive reorganization of the 'xv controls' window. Made room for new command buttons (cut, copy , paste, clear, PadImage, About XV, etc. simplified appearance by tossing many buttons into new 'menu' buttons ('Root', 'Windows', 'Image Size'). Added Feature: Added a 'show/hide hidden files' toggle in the schnauzer windows. (When enabled (as it is by default), it hides all files beginning with a '.'. As such, it's Unix-centric, but so is the rest of the program...) Bug Fix: When 'dragging' files in the schnauzer windows, the window could scroll entirely too quickly (on a fast machine). Added a limit. Bug Fix: Fixed 'window-centering' code (that which pops up windows with an appropriate button centered under the mouse, such as the save window), so that it correctly positions the window. It works on a DEC Alpha running OSF 2.0, under Mwm, Olwm, and Twm. Hopefully, it'll work for you! Enhancement: Added code to display keyboard equivalents in the various menu buttons. Enhancement: Added keyboard equivalents for remaining algorithms, just to be consistent. The equivs are listed in the algorithms menu, and all use the meta key. Enhancement: Got rid of the 'Blur*' choices on the Algorithms menu, and replaced it with a single 'Blur' routine that prompts for a value, making it cleaner, and more versatile, with only a slight convenience trade-off. Keyboard equivalent: 'meta-l' Added Feature: Added a nifty 'Pixelize' algorithm. (Keyboard equivalent: 'meta-p'). Again, operates on the current selection, if any, otherwise it operates on the whole picture. Now you too can make photos look like their from those 'real-life cop shows'. (Non-U.S. folks can just ignore that cultural reference.) Anyhow, one neat feature is that it the pixels don't have to be square. Try something like '16x1' for a neat effect. Added Feature: A 'save selected area' checkbox in the save window. Lets you easily save portions of an image (without cropping, etc). Two notes: if you save 'at displayed size' (the default), only the area of the selection that is visible in the image window will be saved. Alternately, if you save 'at normal size', you *can* have the selection go off the edges of the displayed image (or subimage). Enhancement: You can now enter negative values for the Gamma command in the graphs in the color editor. Negative values produce the same curve as their corresponding positive values, except that they are horizontally flipped. (ie, the curve starts at the top and goes down). (Alan Blanchard (alan@abraxas.mbt.washington.edu)) Bug Fix: Memory leak if '-ncols 0' on a > 1-bit display Change: In the Save window, moved 'File list' checkbox into the Format menu. Enhancement: You can now type TAB key in Load/Save window to do automatic filename completion. It only for 'simple' filenames (ie, no '/' chars, no pipes, no '~', etc.), but it's still a very handy thing. New Feature: Added 'Rotate (Copy)' and 'Rotate (Clear)' algorithms (keyboard equivalents 'shift-meta-t' and 'meta-t' respectively) that let you rotate the image (or the current selection) by any arbitrary amount. The only difference between the algorithms is that the second one clears the old selected area first (equivalent to: 'cut, rotate, paste'), whereas the first algorithm is equivalent to 'copy, rotate, paste') Enhancment: Added 'meta-u' keyboard equivalent for 'Undo all' algorithm. Enhancement: 'Flip Horizontal' and 'Flip Vertical' commands now operate on selected area, if any. (Otherwise, they do the whole picture.) Enhancement: Put a 'progress meter' into most of the potentially time-consuming functions (algorithms, smooth, resize, etc.) Bug Fix: The 'Oil Paint' algorithm now does the Right Thing on color images. (Simply running the grayscale algorithm on the red, green, and blue planes separately was the Wrong Thing, as it introduces goofy fringe effects in colors that weren't originally in the image). Added Feature: New 'blend' algorithm (keyboard equivalent: Meta-b). Takes the current selection (or the whole pic, if no selection), and clears the rectangle such that the edges remain the same color, the center becomes the average color of all the edge pixels, and all other pixels get an appropriate color based on their distance from the edge and their distance from the center. Enhancement: Algorithms (selected from the 'Algorithms' menu) now will only affect the selected area, assuming there is a selection. Otherwise, they will affect the entire image, same as they used to. Change: After deleting the last file in the 'xv controls' list, it will go back to displaying the XV logo. (Tom Hinds (rocker@cs.bu.edu)) Bug Fix: Writing GIF files in the B/W Dithered color mode would result in black & white getting reversed. (Thomas Braeunl (Braeunl@informatik.uni-stuttgart.de)) Enhancement: If you accidentally start tracking a 'zoom in' or 'pan' rectangle, releasing the Ctrl key will abort the operation. Enhancement: 'Meta-8' now toggles between the 8 and 24 bit modes. Change: If you specify '' as the filename in the load window, it will re-load the XV title image. Bug Fix: If the last file in a list was broken in some way and was either shown as Text, or not shown at all, the Next/Prev buttons weren't getting enabled/disabled appropriately. (R.P. Rodgers (rodgers@nlm.nih.gov)) Enhancement: Used to be, when you saved a GIF (or other 'simple' format with no format-specific dialog box), XV would stick the 'saved' filename at the end of the 'xv controls' list. However, if you were in the middle of a bunch of files, this would cause you to 'lose your place'. Folks complained. XV now does the Right Thing (tm). When you save (in *any* format) it adds an entry to the end of the list, but does not move your selection. When you *load* a new file (via the load or schnauzer windows), the name also gets stuck at the end of the list *and* the selection is moved. Change: As the default cursor in the image window is now the 'arrow' cursor, the cursor affected by the '-cursor' option/resource is now the arrow cursor used in all windows. Enhancement: XV now comes with version 3.30 of the libtiff TIFF library. This version should run correctly on 64-bit machines. Note, however that there the TIFF library no longer has any non-ANSI C support, meaning you *must* have an ANSI C compiler (ie, gcc) to compile it. This should *not* be a big problem in 1994... Enhancement: Load and Save 'windows' now point to separate directories. Such a simple, obvious misfeature, I don't know how it's survived this long. (Big Hint: The author doesn't actually *use* the program very much!) Enhancement: Modified/improved 'selection' rectangle handling (formerly called the 'crop rectangle'). It now flashes, making it much easier to find. It also stays around when you zoom, unzoom, pan, or resize the image. This lets you draw a selection, and zoom in on the corners (or whatever), and get the selection positioned perfectly before doing the crop (or whatever). Added Feature: XV now can read and write uncompressed 24-bit Targa files, interlaced or non-interlaced, with the origin in the bottom-left or top-left (by Derek Dongray (dongray@genrad.com)) Change: Redesigned the load and save windows (okay, so it's really only one window...). The number of radio buttons for different image formats was getting out of hand, and taking up a lot of valuable screen real estate. The new load/save window is smaller (well, the save is smaller, the load is now the same size as the save), cleaner, has room for 6 more lines in the directory window, and has a fish in it. A win, by my book. Bug Fix: Found (and killed) memory leak in the Schnauzer, which would occur during icon generation Bug Fix: IRIS RGB i/o code didn't work on 64-bit machines. Added Feature: '-RM' command line option (no X resource equivalent). When specified, upon exit XV will delete *all* files listed on the command line. Handy if you're writing a program, and you want to use XV to display graphics automatically. You write your image(s) out, fork off a background XV to display the image(s), and when the user quits XV, the image files will be removed, saving you the trouble of cleaning up the files yourself. Added Feature: Nifty new 'Grab' dialog box whenever you issue the Grab command. You can now specify a grabDelay from within XV, and you can also automagically hide all XV windows during the grab. Also, now supports 'autograb' command, which waits the specified delay time, and then grabs whatever window the cursor happens to be in at the time. This gives you a way to capture popup menus, rubber-band selections, and other things that require the mouse button to be held down. (Note: AutoGrab searches upward and grabs the 'top-level' window that the cursor is in, rather than just the immediate child window, as it's far easier to take too much and throw away the extra than to take too little...) One note: between the time a Grab or AutoGrab command is issued, from the dialog box, and the time that the command complets, all 'image file changing' commands ('Next', 'Prev', 'Load', etc.) are disabled, (as is Grab), for perfectly good reasons. Enhancement: The '-expand' option (and the 'xv.expand' resource) now takes either a single value (as it used to), or a pair of values separated by a colon. This lets you set different horizontal and vertical expansion/compression factors. (eg, '-expand 3:-4' will make the displayed width 3 times the image width, and the displayed height 1/4th the image height.) Change: 'Relaxed' floyd-steinberg dithering when displaying 24-bit images (in 24-bit mode) on non-truecolor displays. Fewer goofy artifacts. Enhancement: Now (unless '-nostat' is specified) stats filenames specified on the command line. Only 'plain' files will be added to the list of filenames. This lets you type 'xv *' in a directory with subdirectories, and not have the subdirs added as (unloadable) files. Change: Change 'static char' in all bitmap files to 'static unsigned char', as some compilers object to values > 0x7f being assigned to signed char's. Change: Added 'click right button to open menu' string in the XV logo image, just to make things a little more obvious. Added Feature: Changed command-line argument handling. All of the 'flag' options (-perfect, -smooth, etc.) now take '+' or '-' as the first char of the option name. If you use '-' (ie, '-perfect') it *forces* on the option (it used to toggle the option on or off). Similarly, if you use '+' as the first char of the option ('+perfect') it forces *off* the option. This lets you put the program in a known state (regardless of what X resource settings you may have set up). Handy for sysadmins who want scripts using XV to behave the same no matter what X defaults the users may have set up. (idea: Peder Langlo (respl@mi.uib.no)) Change: XV no longer looks in '.Xdefaults-machinename' as a place to find your X resources. The 'gethostname()' call was leading to portability problems, and in any event, you should load up your resources into the resource database (via 'xrdb') when you log in, the way God intended... Added Feature: When cropped (or zoomed), ctrl-Middle in the image window will let you pan the visible region of the image around, which is much cooler than zooming out and zooming back in on a different area. (idea: Peder Langlo (respl@mi.uib.no)) Enhancement: There's now a '..' entry in the load/save window file list, to make maneuvering slightly easier. Added Feature: XV now can read and write uncompressed 24-bit Targa files (by Derek Dongray (dongray@genrad.com)) Enhancement: XV can now handle 16-bit greyscale TIFF files. (Leon Avery (leon@eatworms.swmed.edu)) Bug Fix: Memory leak in 24-to-8 bit conversion routines found and removed. (Scott D. Heavner (sdh@po.cwru.edu)) Enhancement: XV now has a 'chdir' button (and menu item) in the Schnauzer window. It lets you directly chdir to some other directory without going through the old 'up to the root and then down one dir at a time' process. Change: Typing '^C' in schnauzer windows now does a 'chdir' command, rather than opening/closing the 'xv comments' window. To get the comment window, type '^C' in the image window. Change: XV now eats BadWindow errors on the X_GetProperty request. These happen on certain SGI X servers after the 'snapshot' program has been run. The window hierarchy gets trashed by snapshot. (Run 'xlswins' if you want to see this.) (Ben Simons (ben@lewis.vislab.su.edu.au)) Bug Fix: The 'edge detection' algorithm wouldn't detect edges along the \ direction. Better edge detection algorithm has been added. (Though the old is still there for the 'embossing' effect. (David Robinson (drtr@mail.ast.cam.ac.uk)) Bug Fix: A4 and B5 paper sizes in PostScript save dialog were slightly wrong. Enhancement: XV now supports 'gzipped' files, as well as 'compressed' files. Needless to say, you need to have the 'gunzip' program installed on your system for this to work. (Jean Liddle (jliddle@mrcnext.cso.uiuc.edu)) Enhancement: Added 'A3' paper size in 'save as PostScript' dialog box. Bug Fix: BMP file reading wasn't working on files created by ImageMagick. (Roy Johnson (rjohnson@shell.com)) Enhancement: XV now sniffs out whether or not you have a 24/32 bit TrueColor or DirectColor visual, and if so, uses it by default (rather than always using the 'Default Visual' of the display, which is generally an 8-bit PseudoColor visual, even on 24-bit systems). Also, both the '-visual' option and the 'xv.visual' X resource now also take 'default' as a value, which means 'use the default visual of the display', for folks who want 'the old behavior'. Change: Modified the 'Timer()' function in xvmisc.c to use select() instead of 'setitimer()', which let me get rid of all the FOO_SIG macros and such in xv.h, and basically get rid of one of the primary portability annoyance. Bug Fix: In the Schnauzer, when generating icons, if it decides a file is potentially an XBM file, loads it, finds out it isn't, it will be displayed as an UNKNOWN icon (?), instead of an ERROR icon. Change: When tracking pixel values in the image window, it now displays the color of the pixel in Hex, as well as in decimal, so that you can use this value directly in X color specifications, without needing to do the dec->hex conversion by hand. Bug Fix: In the 'xv load' window, if you clicked below the 'Load All' button, you could get a 'Prev Name' button to appear. (Erwan Moysan (Erwan.Moysan@irisa.fr)) Bug Fix: .xvpics subdirectories are now created with the same permissions as their parent directories. Likewise, thumbnail files (in .xvpics dirs) are now written with the same permissions as the original files. Bug Fix: In XV 3.00, the PDS/VICAR module got screwed up somehow, and no longer worked correctly. Fixed. Change: Stuck SysV-style signal handler definitions and rand/srand defs in xv.h, for better compatibility (David Brooks (dbrooks@osf.org)) Bug Fix: 'Pass 2 color allocation' could potentially be performed on a visual type with no colormap, which would be a bad thing, believe me. Bug Fix: '-loadclear' wasn't working correctly Bug Fix: Potential segmentation fault when Uncompressing files fixed. (Dana Jacobsen (jacobsd@solar.cor2.epa.gov)) Bug Fix: If printing XV-generated Color PS files on a Grey/BW PS printer, the printer may have run out of memory, due to a memory leak in the color->gray PS code. (Klaus Schnepper (df40@master.df.op.dlr.de)) Bug Fix: The '-hist' and '-norm' options weren't actually working. Bug Fix: If you loaded a GIF89 file with a lot of ignored-by-xv extensions, and you didn't have the info or controls windows up, the constant popping up of 'warning' messages was real annoying. They don't do that anymore. Enhancement: If you specify the '-quit' option, XV turns off any '*map' options (-cmtmap, -cemap, -imap, etc.) you may have turned on, as you won't have an opportunity to *use* any of the windows before the program exits. No need to map them. Bug Fix: XV now correctly positions the window on initial load (ie, 'xv -max' will now work again) Bug Fix: When you loaded a new image, if XV felt a need to move the window, it would draw the new image at the old window size, and then draw it again at the new image size. This was a major inefficiency with 24-bit images. Enhancement: 'Remove' key on DEC keyboards now functions like '^D', so it can be used to delete files, etc. Added Feature: XV can now read a variety of Amiga IFF ILBM formats. (Thomas Meyer (i03a.zfn.uni-bremen.de) Change: XV should now recognize PS files that start with '%!' (as it did) and with '^D%!' (as generated by MS-Windows 3.1) Bug Fix: If you use '-poll' and '-maxpect', only the first image would be shown 'big'. (Bruce Labow (labow@itd.nrl.navy.mil)) Change: 'Relaxed' getwd handling. You can now maneuver through directories even if you can't read the contents of one of the parent directories (ie, mode 'rwx--x--x'). All parent directories must have execute permission, however. (Andrew Brooks (arb@comp.lancs.ac.uk)) Change: Cleaned up 'file type' handling code in source, which should make it easier to build XV on 'non-standard' platforms. (Cameron Simpson (cameron@cse.unsw.edu.au)) Enhancement: XV previously only recognized files that began with '#define' as being (potentially) XBM files. It now also will treat files that start with '/*' as potential XBM files, which should cover nearly all the XBM files out there. Bug Fix: If you moved or copied files from one schnauzer window to another, and for some reason the files failed (ie, 'moving' from a write- protected directory), the icons that failed to move would still be lit (as they should be), but they didn't *think* they were lit! Bug Fix: When moving/copying files via the schnauzer, it would always create '.xvpics' subdirectories in the destination folder, instead of "only when the source folder has a .xvpics subdirectory", as was intended. Enhancement: 'relaxed' the AutoCrop algorithm for 24-bit images. Since 24-bit images (JPEG, in particular) tend to have some noise in them, the 'everything must be equal' criteria of the normal autocrop algorithm would prevent any cropping from happening. The new algorithm (which only affects 24-bit images) crops lines if all the pixels are within a certain percentage of one and other. (Paul Close (pdc@sgi.com)) Bug Fix: BMP file i/o fixed. 24-bit files weren't done correctly, and certain files would blow up that Windows-based programs would handle correctly. (Pesky vague format specifications...) (John Walker (kelvin@autodesk.com)) Bug Fix: Unified 'cursor keys' into one function. Certain keyboards generate an interesting variety of keysyms when you hit the 'pageup' 'pagedown', 'home', and 'end' keys (and shifted arrow keys), and I had code to deal with that problem scattered around the source. Practical upshot: 'pageup/down' might work in certain controls/ windows, and not others. Bug Fix: XV would crash if you tried to grab a rectangular region of the root window (and both the starting and ending points of the rect were in the root window). Bug Fix: Memory leak in xvpbm.c (Joe Peterson (joe@avs.com)) Bug Fix: XV would crash if you used '-nopos' (Nick Sayer (mrapple@quack.kfu.com)) Change: All files in the distribution should be 14 chars or less (to avoid SysV name-length limitations on some systems) Change: Broke up exceedingly large functions in xv.c and xvevent.c, as they tended to annoy compilers and optimizers... Bug Fix: Use of GS_LIB in Makefile broke if folks had it defined in their environment already. Bug Fix: XV assumed that 24-bit deep visuals had 32 bits per pixel. While this is generally true, apparently there are some servers that only want 24-bit pixel values. (Steven Schoch (schoch@starnet.com)) Bug Fix: It would crash if it tried to draw an MenuButton that had no menu associated with it yet. (A timing issue that occurred on some systems) Bug Fix: If you tried to use '-root' and '-gamma' simultaneously, it'd crash. Now it doesn't. Bug Fix: On some systems, XV would crash when clearing an old root image and installing a new one. Added Feature: Additional options to 'bggen'. You can now specify the size of the generated image with '-g geometry'. The generated images are now by default in PPMRAW format. You can generate 'ascii' images by using the '-a' flag. You can now ROTATE the generated image by any arbitrary amount with the '-r rot' flag, where rot as a (counter-clockwise) rotation, in degrees. Enhancement: 'bggen' has been fixed. It now automatically senses the display size, and by default, generates an image of that size. (PeterVG (pvgunm@polaris.unm.edu)) Change: In XV 3.00, I went to a somewhat faster (serpentine) color dithering algorithm (used in conjunction with Smoothing on non-TrueColor displays, when in 8-bit mode). No one much noticed the speed improvement, and several people complained that images now looked worse than they used to, so I've put it back the way it was. (Kenny Zalewski (zalewk@rpi.edu)) Enhancement: If you are running XV in 'locked 8-bit mode', and you load a JPEG image, XV will now use the JPEG quantizer, which produces better results than the normal XV quantizers. This makes XV 3.00 behave like it did in XV 2.21. (Jim Lick (jim@pi-chan.ucsb.edu)) Bug Fix: xvsunras.c still had some problems on 64-bit machines. (Dave Hill (ddhill@zk3.dec.com)) Change: Twiddled code in xvsmooth.c. Certain compilers complained about a potential divide-by-zero (not that it could ever happen, but try telling the compiler that...) Change: Twiddled code in xvps.c. Optimizer in IRIX-4.0.5 broke a calculation. Expression has been simplified. Bug Fix: YCbCr->RGB conversion in xvtiff.c wasn't being done correctly, according to the TIFF 6.0 standard. (Karsten Spang (krs@kampsax.dk)) Portability: Added explicit typecasting to a few lines of xvtiff.c (HP compilers objected.) Portability: Changed intances of '#ifdef macII' in xv.h to '#ifdef aux' (Declan A. Rieb (darieb@sandia.gov)) Bug Fix: XV wouldn't correctly read XBM files with 1-digit-long values (ie, '0x9' instead of '0x09'). Fixed. (spotted by: Berthold Dettlaff (dettlaff@informatik.uni-stuttgart.de)) Bug Fix: xvtiffwr.c now writes out XRESOLUTION and YRESOLUTION flags, which are apparently required by some other tiff-readers (Larry W. Virden (lwv26@cas.org)) XV 3.00a intermediate bug-fix release ------------------------------------- Bug Fix: core dumps in schnauzer fixed. (br->lit wasn't getting zeroed when you moved files to another directory) Bug Fix: To vdcomp.c. Strings buffers to hold filenames were too short. (Anthony A. Datri ) Bug Fix: If you put an image using the Std. Colormap into the root window (ie, a 24-bit image on an 8-bit display), and exited XV, the colors were freed (and would get overwritten) Bug Fix: 'Update' command in Schnauzer now checks both 'mtime' and 'ctime' fields when comparing dates of a file and its thumbfile. Bug Fix: XV load window didn't correctly handle 1-character top level directory names (ie, '/u'). XV 3.00 Release --------------- Enhancement: Faster 332 dither algorithm when displaying 24-bit images on non-TrueColor/DirectColor displays. Added Feature: 'trimming keys'. You can now easily trim off one pixel from any edge of an image by pressing Ctrl and one of the arrow keys while inside the main window. Now you can use the cropping rectangle for a first 'rough cut', and do the precision work with the trimming keys. Enhancement: Added '-grabdelay' command line option (no resource), which lets you specify a delay between the time the 'Grab' command is issued, and the time that the cursor changes becomes owned by XV, regardless of what window it's in. This lets you hide the XV windows (or whatever) before the actual screen grab takes place. The delay can be set to 0 (the default) up to 15 seconds. (Jason Berri (berri@aero.org)) Bug Fix: Was crashing if you handed it a gif with multiple images in it. Change: Switched it back so that when you Delete a file in the xv controls list, the next file in the list (if any) is automagically loaded. Change: Broke huge series of 'else if's in xv.c into two halves. Broke some compilers (on VMS and some PC Unixes) (Rick Dyson (dyson@iowasp.physics.uiowa.edu)) Change: Improved resource-handling code. No longer necessary to define X11R5, and should work on certain HP/Apollo workstations where it didn't used to. Change: Modifications to make XV somewhat more POSIX compliant. (Mark W. Snitily (mark@zok.sgcs.com)) Bug Fix: Changes to xvgrab.c to make it work on 64-bit machines. (Matt Thomas (thomas@netrix.lkg.dec.com)) Change: migrated all memcpy(), memcmp(), memset(), and bcopy(), bcmp(), bzero() calls to xvbcopy(), xvbcmp(), and xvbzero() functions in xvmisc.c. Necessary because the b*() routines don't exist in Solaris, and not everyone has the mem*() routines (and besides, memcpy() doesn't even work correctly) Added Feature: Added '-icgeometry' cmd-line option (and 'iconGeometry' resource) to specify initial position of the icon when you start XV in '-iconic' mode Added Feature: XV can now display multi-page (currently only PostScript) files. If you are viewing a multi-page file, the title of the image window will show 'page 1 of 37' (or whatever) as an indication. You can use the PageUp and PageDown keys (Next and Prev on some) on your keyboard to do page through the file, and you can type ctrl-P to pop-up a 'go to page #' dialog box. These keys must be typed in the image window. Enhancement: Added '-name' command line option (no corresponding resource) that lets you specify the string to be displayed in the image window's titlebar. Useful if you're calling XV from some other program, and you don't want the titlebar to say 'xv /tmp/prog2315a' or something like that. (Idea from: Bill Silvert (silvert@biome.bio.ns.ca)) Added Feature: XV can now read and display PostScript files, as long as you have the 'Ghostscript' package installed. Added '-gsdev str', '-gsgeom geom' and '-gsres int' command-line options (and gsDevice, gsGeometry, and gsResolution X resources). Thanks to Michael Gleicher (mkg@stealth.plk.af.mil) for the idea, and thanks to Harald Hanche-Olsen (hanche@ams.sunysb.edu) and L. Peter Deutsch (ghost@aladdin.com) for PostScript help. Bug Fix: Minor memory leak in xvgrab.c fixed. (Tony Sweeney (sweeney@ingres.com)) Added Feature: Added '-drift dx dy' option (and 'driftKludge' resource) for the benefit of folks who experience a 'drifting' of the image window whenever it's resized, etc. If the window drifts down and to the right, use negative values to compensate. If the window drifts up and to the left, use positive values to compensate... Change: Changed 'schauzer' cmd-line opts and resources to: '-vsdisable' '-vsgeometry' '-vsmap', '-vsperfect' and vsDisable, vsGeometry, vsMap, vsPerfect Added Feature: XV now reads some of the more common types of PCX files (1-bit-per pixel, 1-8 planes and 8-bits-per-pixel, 1-plane). (thanks to Eckhard Rueggeberg (Eckhard.Rueggeberg@ts.go.dlr.de)) Added Feature: Added a 'file list' check box in the Save window. When selected, XV will write out the list of file names currently loaded into the 'xv controls' window, for use with the '-flist' option described below. Added Feature: Added the '-flist' option and 'fileList' resource. Both let you hand XV a textfile that contains a list of image filenames, one per line. When using the fileList resource, be sure to specify the complete pathname to the filelist file, so that XV will be able find it no matter what directory you start XV from. (Brian Gregory (bgregory@megatest.com)) Enhancement: When '-quit' option specified, and you *aren't* using the root window, *any* button press or key press inside the main image window will exit the program. Use this if you're calling XV from some other program, and only wish to view a single image, and be donw with it... (Stephen Mautner (stephen@cs.utexas.edu)) Enhancement: Added semi-useful '-nofreecols' option. Only has an effect when running a slideshow (with the '-wait' option). Prevents the freeing of colors between images, thereby avoiding ugly effects on PseudoColor displays. Of dubious merit, as later images will look worse (if they use different colors than the first images), and XV *REALLY* isn't meant for doing animation. For low- speed slideshows, you're best off *not* using this option, because every image will get the 'right' colors. See the '-loadclear' option to avoid nasty color-reallocation effects... Bug Fix: When polling, if the file doesn't exist, XV will wait for it to be created. Bug Fix: Auto-apply while dragging didn't work the 'first' time you tried to use it. Change: When running XV in -ncols 0 mode (or, running on a 1-bit display), the default image (the XV logo) is generated differently, so as to be easier to read. Enhancement: New version of JPEG library (version 4a) hooked into XV. JPEG Save dialog now has a 'smoothing' dial. JPEG files now support comments. Enhancement: New version of TIFF library (version 3.2) hooked into XV. Bug Fix: When you're doing a slideshow (with the '-wait' option), XV will now determine if the image window is iconified. If it is, it *won't* wait for the window to be drawn before starting the 'wait' period. Previously, if the window was iconified, XV would sit there (and not move on) until you deiconified it. Needless to say, I'm sure *someone* perferred the previous behavior... Oh well! Added Feature: Added '-mfn' and 'monoFont' string resource. Lets the user specify what font to use for TextView windows, and other places where the mono-spaced font is used. Enhancement: GIF, and PBM should now have slightly more informative info when you build icons in the schnauzer (ie, GIF87/89 and Raw/Ascii PBM/PGM/PPM) Added Feature: 'License' button now hooked up. Gives you the current licensing info on XV. Enhancement: When opening up a schnauzer window that will be displaying the same data as an already existing schnauzer window (ie, when using the Open Win command in the schnauzer), the icon data and such is just copied, rather then being re-read from disk. MUCH faster. Enhancement: Comments are now written in formats that support comments (GIF, TIFF, PBM, PM) Added Feature: Two new 'root' display modes, symmetrical tiled, and symmetrical mirrored. (Dave Lampe (djl@ptc.timeplex.com)) Change: You can now TextView a compressed file, and it'll display the uncompressed data. Bug Fix: TextView windows now show correct # of lines (in ASCII mode) for files/comments/whatever that end with a \n character Enhancement: XV should now work on 5-bit displays. Not that there should *be* 5-bit displays, but that's not my problem... Change: 'Expansion' field in info window is now shown in terms of percentages, rather than factors, in keeping with the SetSize command. Change: Stopped making the pop-up dialog windows be transient windows of some other XV window, as (what with the keyboard equivalents and such), it's very difficult to determine which is the appropriate 'parent' window. Given the mwm restacks windows so that the parent is right below the pop-up, this is very annoying when you issue a command in some window, and some other window leaps in front of you. Added Feature: Added 'SetSize' command ('S' shortcut). Pops up a dialog box that asks you what the displayed image size should be (in pixels, or expansion percentages) Enhancement: Whenever you create or delete a file the browser and Load/Save windows will automatically rescan (if necessary) Added Feature: Added '-cmtgeometry' option and 'commentGeometry' resource to specify size/position of 'comments' window. Added '-cmtmap' option and boolean 'commentMap' resource to specify whether comment window should be mapped when XV is started. Added Feature: Added a 'comments' window to display any comments that might be found in the current loaded image file Added Feature: Added '-tgeometry' and 'textviewGeometry' resource to control size and positioning of textview window(s) Enhancement: 'compress'ed file handling improved somewhat. Can now deal with piped-in compressed files, or compressed files that don't end with '.Z' Enhancement: You can now (probably) use shift-up-arrow and shift-down-arrow on keyboards that don't have 'PgUp' and 'PgDn' keys, and use shift-PgUp and shift-PgDn on keyboards that don't have 'Home' and 'End' keys. Rev: 12/7/92 (version 2.36) ------------------------------ Bug Fix: Bug found in GIF file output, involving suboptimal hash tables, or something like that. (Tom Lane (tom_lane@g.gp.cs.cmu.edu)) Bug Fix: If a failure occurred while writing a GIF file, XV would exit with a fatal error. It'll now just complain, but continue to run. (Spotted by Chris Newman (chrisn+@cmu.edu)) Added Feature: Now reads and writes both Grayscale and TrueColor IRIS 'rgb' files. Can read both normal and rle-encoded images, always writes rle-encoded images. (Thanks, Paul Haeberli (paul@manray.asd.sgi.com) Change: Deleteing a file from the control window now no longer loads the next image in the list. As a result, '-keeparound' (and the resource) has been removed, no longer having an effect. Bug Fix: '-polled' was occasionally loading a 'blank' image. Bug Fix: saving 'smoothed' or 'dithered' images was saving 'raw' images instead. Bug Fix: fixed insidious little color freeing problem that would occur whenever XV loaded a 'failed' picture (and hence, brought up the default pic... Bug Fix: Various things were depending on the 'current working directory', which is now a fairly vague concept, what with a load/save window and several schnauzers, all of which can be pointing at different directories... Enhancement: When dragging a selection rectangle in the schnauzer, if you move the cursor far enough above or below the icon window, the window will start scrolling in 'pages' rather than a line at a time. Rev: 11/9/92 (version 2.33) ------------------------------ Enhancement: The Update button in the Schnauzer now calls 'scanDir()' first, and also displays new icons as it generates them. Bug Fix: Smoothing wasn't automatically happening if the image was initially displayed shrunk/expanded (for whatever reason). Change: Let the titles in the Schnauzer get a little longer before '...'ing them. Enhancment: Much improved 'Grab' command handling. You can now grab windows that have a private colormap, and it also works with windows of varying depths (handy if you have one of those X servers (like an Iris) that is normally in 8-bit pseudocolor mode, but *can* open 24-bit windows simultaneously.) Bug fix: '' was getting put in the control window's name list, which was sort of pointless, since it can never be reloaded or anything. Change: Now, displays both the filename and the parent directory's name on the image window and icon to help you differentiate between two images with the same name. (ie, you're comparing the images "/my_archives/gif/naughty.gif" and "/tmp/incoming/naughty.gif". XV will now display 'gif/naughty.gif' and 'incoming/naughty.gif' in the two window's titlebars. Assuming, of course, that your WM *does* titlebars...) Change: Put back the 'auto-install' colormap on load behavior when running in '-perfect' or '-owncmap' modes. Bug fix: it was apparently possible to get double-slashes in the control window name list. Hopefully less so now. Bug Fix: xv now fills in the 'WM_COMMAND' property of the main window, in accordance with the ICCCM. (Eric Rescorla (erk@eitech.com)) Added Feature: Added '-bperfect' and boolean 'browsePerfect' resource to control whether or not the visual browser should install it's own, private colormap. By default, it *does*. Added Feature: Added a 'Load All' button to the Load window. Copies the names of all 'regular' files in the current directory into the control window list, for e-z viewing. Added Feature: Multiple browser windows. Added Feature: Added a cool 'auto-apply while dragging' check button in the color editor. It can only be turned on while you're in 'read/write' color mode, and is by default. When enabled, image colors are twiddled *while* you operate the various controls in the color editor window, not just after you release the controls. There's a 'dragApply' boolean resource that lets you turn off such behavior (if, for whatever, it's *still* too slow on your machine). (Major League Thanks to Chris Weikart (weikart@prl.dec.com) Enhancement: In the visual browser, now attempts to load executable files as well, when generating icons. If the file is a known format that just happens to have it's executable bit turned on, an icon is generated. Otherwise, the icon is left the default 'application' icon. Bug Fix: Loading '~/whatever' in the Load window was putting a bogus (un-globified) string in the Control window list Enhancement: Whenever you successfully 'save' a file (in the Save window), the written file's name is added to the Control window list, for e-z reloading... Enhancement: The infamous (to me, at least) 'purple problem' on HP's and some other things has probably been fixed. I can't test it, so I can't verify this. If you don't know what the problem was, don't worry, you didn't have it. Change: Added 'version #' string to image window titlebar. Enhancement: Pop-Up warning/confirmation windows are now 'attached' to the correct windows, for the most part. Added feature: Dopey 'warning message' pops up when you switch from 24 to 8 and subsequently from 8 to 24. Added feature: When allocating colors in 'stdcmap' modes, it now tries a little harder... Added feature: You can now specify a specific visual to use by using '-visual ' where vid is the hexadecimal visual ID. You can get visualID's by running 'xdpyinfo'. (Formerly, you could only specify a class of visual (eg, TrueColor), and XV would pick the 'deepest' one of those available.) Note: If your root window and specified visual have different depths, you will *not* be able to display images in the root window. Bug Fix: 'Landscape' postscript had its preview incorrectly generated. Bug Fix: Grayscale compressed postscript wasn't quite correct. (John P. Nelson (jpn@genrad.com)) Bug Fix: Postscript 'bounding box' comment was incorrect when writing in landscape mode. (John Amanatides (amana@cs.yorku.ca)) Added: '-8' and '-24' options (and boolean 'force8' and 'force24' resources) to force XV to remain in either 8- or 24-bit mode. Bug Fix: Patches two 2-bit X support for NeXT machines. (Werner Randolf (evol@brian.uni-koblenz.de)) Rev: 10/8/92 (unreleased version 2.29) ---------------------------------------- Added: '-dir' (and 'searchDirectory' string resource) to specify a default place to look for files. When you start XV, it will 'cd' to this directory, so it will be the default directory for the Load, Save, and Visual Browser windows. Also, you can (on the command line) specify 'simple' names. It will first look for the file in the directory that you were in when you started XV, and (if not found there) it will look for the file in the specified search directory. Added: '-hist' and '-norm' options (and boolean 'autoHistEq' and 'autoNorm' resources) to automatically perform Histogram Equalization and Normalization whenever an image is loaded. Added: A '-viewonly' option that disables *ALL* user input, and as a consequence, prevents the user from opening any of the various XV windows. They'll only see the image window, and they won't be able to do anything with it. Useful in the case that you may want to use XV in some sort of canned demo (or other environment in which you don't want people to have access to the file system (the load/save window) and such.) Note that it isn't possible for the user to Quit the program, either, so you'll almost certainly always want to use the '-wait' option to make the program exit after some amount of time. (Or, alternately, you can just kill the XV process from whatever program started it.) (idea from Larry W. Virden (lwv26@cas.org)) Added: When using XV for format conversion, it can be darned annoying that whenever you load a file, it sets the format/colors controls in the Save window to appropriate values for the loaded image. Likewise, if you're printing images, or piping them to some program, it's annoying that everytime you load an image, the default 'save as' filename gets put back to the loaded image's filename. The fix: two new buttons in the Save window, 'Prev Set' which restores the format/color settings that were used on the last save operation, and 'Prev Name', which restores the name that was used on the last save operation. Change: IntSize button now shrinks things to integer compressions, as well as integer expansions. For example, if the current expansion ratios were .70 x .80, and you hit IntSize, the new ratios would be .50 x 1.00 (as .70 is closer to 1/2 than it is to 1, and .80 is closer to 1). Likewise, it will shrink things to 1/3, 1/4, 1/5, and so on. Added '-rotate deg' and 'autoRotate: int' options to automatically rotate images (in 90-degree steps) when they are loaded. Valid values are 0, +-90, +-180, and +-270. Added '-hflip' and '-vflip' (and boolean 'autoHFlip' and 'autoVFlip' resources) to automatically flip images horizontally and vertically when loaded. Change: Now, when 'large' images (larger than the screen) are loaded, they are shown at 'MaxPect' size, rather than being halved or quartered. Added a new '-crop x y w h' option that lets you automatically crop to some specified rectangle when an image is loaded. Note that the entire image is still loaded, and available, and you can hit 'UnCrop' to display the whole image. Mainly useful to view a small section of the weather maps, or something like that. Note that there is no corresponding resource for this option. Renamed the old '-crop' option (which automatically did an 'AutoCrop' operation) to '-acrop'. The boolean resource 'xv.autoCrop' still specifies whether or not to automatically do an AutoCrop. Added a '-raw' option (and 'autoRaw' boolean resource) basically to complete the '-dith' and '-smooth' options. Can be used to turn off the default automatic dithering that takes place when you're using the 'standard colormap' Added '-4x3' option (and 'auto4x3' boolean resource) to automatically do a 4x3 command on any loaded pictures. Added '-preset' option and 'defaultPreset: int' resource that lets you make one of the four presets in the color editor window temporarily be the 'default' preset. Useful if you set the presets up to correct the colors for various monitors that you use, or alternately, if you set the presets up to 'do' something useful... (idea from Ricky KeangPo Ho (kpho@sabina.berkeley.edu)) Bug Fix: Whenever you load a file, its name gets put into the Control Window's list. XV now checks to see if the name is already *in* the list, and thus avoids putting duplicate names in the list. (Rod Summers (rsummers@ard.fbi.GOV)) Added stuff to the Display Modes button. You can now turn on/off these options, interactively, while running the program: -perfect, -owncmap, -stdcmap, -rw It's pretty cool, since if you're like me, you just normally run XV in its default mode (read-only color cells, no colormap installation). If you suddenly decide you want to extensively putz around in the color editor, you can, on-the-fly, turn on read-write colorcells, which makes things *much* faster. Added '-stdcmap' option and 'useStdCmap' resource. Instead of allocating a custom set of colors for each image, it will instead allocate a general set of colors once, and display all subsequent images using these colors. The images don't look as good as if they used image-specific colors, but it avoids the ugly rainbow effects between images, since all images use the same colors. Important if you're doing 'animations' using '-wait'. Also, it speeds things up slightly. Note: normally when you load images while using the StdCmap, they will be automatically dithered for you, as they look pretty nasty when they aren't dithered. The exception: If you're viewing an animation (which is one of the main reasons for the '-stdcmap' option), and you've said '-wait 0' (which means 'display as fast as possible), the auto dithering is turned off, to increase the speed of the animation. You can still manually turn it on in this case by using the '-dith' option, or just using '-wait 1'. Note: There are a couple different sizes of 'standard' colormaps. If you're on a TrueColor/DirectColor display, it will use a 3/3/2 colormap. Otherwise, it will try to use a 6*6*6 colormap, a 2/2/2 colormap, or a 1/1/1 colormap, based on '-ncols' (or the depth of your display, if it's less than 8 bits). You can manually force it to use a smaller colormap than it would normally use by setting '-ncols'. (ncols < 216 will keep it from using the 6*6*6 cmap, and ncols < 64 will keep it from using the 2/2/2 cmap...) Other note: normally, the use of the -stdcmap option will *not* affect how the image is saved (should you decide to Save an image). You can, however, write out images using the standard cmap by selecting the 'Reduced Color' option in the Save box. Deleted '-nglobal' option and resource. Bug fix: 'Maxpect' button in PostScript window wasn't working correctly in landscape mode. (Jim Belonis (belonis@dirac.phys.washington.edu)) Turned off 'ceditColorMap'. Now, by default, the color editor will be shown in the 'normal' colormap, rather than the image's colormap (when using '-perfect' or '-owncmap). This can be confusing when using the colormap editor, as the cells will *not* be shown in their correct colors, but it gets around the problem of not being able to *use* the color editor because it's being displayed in non-contrasting colors. Added feature: Now, when you save a file, it prints the # of bytes written. Useful, if you want to know how well your image was compressed. Bug fix: Wasn't correctly displaying on LSBFirst 16-bit displays (Stardent) (Arman Rivard (frog!arman@eddie.mit.edu)) Added some 'useful' default settings for the Color Editor presets (1-4). #1 is a 2-intensity setting. Image will be shown in black and fully- intense colors. Sort of makes pictures look like the credits to 'Saturday Night Live' did at some point in the past. #2 is a 8-color setting. Image will be shown in black, blue, green, cyan, red, magenta, yellow, and white #3 is a 'temperature' pseudo-color mapping for grayscale images. #4 is a 'geographic map' pseudo-color mapping for grayscale images. Added '-bdisable' option (and browseDisable resource). Turned off the 'autoClose' behavior, by default. Iconifying the image window will *not* affect the other windows. To get the old behavior (where iconfiying the image window iconified everything else), just specify the '-close' option, or set the 'xv.autoClose' resource to 'True'. Change: Changed '-browse' option to '-lbrowse' (and '.browseMode' resource to '.loadBrowse'), so as not to conflict with new 'visual browser related options/resources. ('-bmap' and '-bgeom' options and '.browseMap' and '.browseGeometry' resources) Added Feature: a '-poll' option. If turned on, XV will (attempt) to recognize when (if) the currently displayed file changes, and if so, it will reload it. This should let you easily use XV to monitor ALL SORTS OF THINGS, such as the progress of slow ftp transfers, the weather map (assuming you have the thing installed to automagically download the things and put the latest one in some standard place, say "current_weather.gif" or whatever...). You could even use XV as a sort of framebuffer, to allow otherwise non-X programs to display graphics. Just have your program draw on its own internal 'frame buffer' (just a hunk of memory), and periodically write it out to a file. (As I've mentioned to anyone who'd let me, "The PBM/PGM/PPM file formats are *trivial* to write. Any program that manipulates images should be able to write a PBM/PGM/PPM file..."). Anyhow, periodically write stuff to a file, and have XV display the file with the '-poll' option turned on, and voila!, an output-only framebuffer for X workstations. Added Feature: Added an 'oilpaint' function to the 'Algorithms' menu. I got the basic idea from 'pgmoil.c', written by Wilson Bent', who in turn got it from this book called "Beyond Photography", written by some dude named 'Holzmann'. Bug fix: if your image only had two colors in it, and you wrote it out as a Sun Rasterfile, it would turn out in black and white, regardless of the 'FullColor/Greyscale/B&W Dither' setting. Added Feature: 'Algorithms' menu. Now you can run blurring algorithms, edge detection, 'tinfoil' effect, and such on an image. Note that these algorithms generate a new 'image', rather than just playing around with the way that the image is displayed. Enhancement: Timer() function should work better on SGI machines. (Fernando D. Mato Mira (matomira@ligsg13.epfl.ch)) Added Feature: '-gamma gval' option and '-cgamma rval gval bval' for setting gamma values in the Color Editor graphs from the command line. Added Feature: 'IntExpnd' button (keyboard equivalent 'I') rounds the width and height expansion factors to the nearest integer. Bug Fix: GIF87 files with an aspect ratio in them weren't being parsed properly. Enhancement: Many cleanups and the Imakefiles for the JPEG and TIFF subdirs (Jonathan I. Kamens (jik@pit-manager.mit.edu)) Enhancement: Modifications for compiling on ODT 2.0 systems. (Mike Patnode (mikep@sco.com)) Enhancment: If using '-root -maxpect' you can now use '-rmode' to specify how it will be displayed (though it will still default to the 'root, centered' style). (Ted Grzesik (tedg@apollo.hp.com)) Enhancement: Modifications to get XV to compile on the Interactive Unix System (Eam Lo (eam@netcom.com)) Feature: Added '-random' command line option. Mainly used in conjunction with '-wait' to produce 'random' slideshows. Rather than running through the files in the order that they were specified on the command line, it will order them into a random sequence. Each file will only be displayed once. (Unless '-wloop' is also turned on, in which case each file will be displayed once per 'loop'.) If used without '-wait', it will randomly pick one of the specified files to be displayed first. (Tim Ayers (ayers@mermaid.micro.umn.edu)) Bug Fix: Wasn't properly truncating leading path off of names displayed in control panel (after 'Load'ing a new file). (Elaine Chen (eychen@Athena.MIT.EDU)) Fixed bug in writing compressed PostScript. (Bill Hess (hess@tethys.apl.washington.edu)) Fixed bug that would crash on certain systems when trying to display a root image. (Eam Lo (eam@netcom.com)) Fixed bug that caused XV 2.21 (in 'root' modes) to eventually crash the OpenWindows X Server. (thanks to Jeremy Lawrence (jeremy@snrc.uow.edu.au) for his help in tracking the problem down) Added BMP (Microsoft Windows 3.x) format, for both reading and writing. Note: while it reads RLE4 and RLE8 compressed formats, it only writes in the uncompressed format. Given how few RLE4/RLE8 BMP files I've seen out there (read: 'none'), this shouldn't be a big problem. Certain warning messages are now printed to stderr if neither the control or info windows are open. RLE file reading was busted. Wouldn't read colormapped RLE files, nor would it read RLE files that didn't have a background color specified. (reported by Peter Miller (pmiller@topaz.bmr.gov.au)) added window classes 'XVps', 'XVjpeg', 'XVtiff', 'XVconfirm' for the postscript, jpeg, tiff, and popup windows, respectively, so Motif users can do things like this: Mwm*XVroot*clientDecoration: none Mwm*XVcontrols*clientDecoration: -resizeh XV should stop 'homing' windows into the top-left corner of virtual root windows. (Daren W. Latham (dwl@mentat.udev.cdc.com)) Support for 2-bit MSBFirst machines. (Dale Luck (dale@ntg.com) 1-bit Sun Rasterfiles weren't being written correctly. (Lars Bo Nielsen (lbn@hugin.dk)) Image colors are now preserved 'as long as possible' when in '-perfect' or '-owncmap' modes and changing images, thus minimizing the amount of time the image is shown with the 'rainbow effect' and maximizing the amount of time the image is shown with the correct colors. Image was being unnecessarily cleared when in '-perfect' or '-owncmap' modes. When saving images in B/W stippled format, *and* the image only has two colors in it, XV no longer does an explicit (and unnecessary) call to the the Floyd-Steinberg ditherizing routine. Not only will saved images be *exactly* what was on the screen (which wasn't necessarily the case, before), but it also saves a tremendous amount of work if you're huge b/w scanned image, which more and more folks seem to be doing. (Thanks to Lester Ingber (ingber@umiacs.umd.edu) for complaining about this misfeature) Added '-iconic' option, to start program with image window iconified. Gratuitous three-d-ification of most of the doo-dads, at least on color systems. Changed mouse button usage in Grab command. Button1 grabs a window, Button2 grabs an arbitrary rectangle, and Button3 cancels. (To be consistent with 'Button2' dragging a cropping rectangle in the image.) Bug fix: Shifted-arrow keys didn't work in Postscript window on OpenWindows servers. (Lester Ingber (ingber@umiacs.umd.edu)) Bug fix: Cleaned up some potential memory leaks. Bug fix: "xv -rw -mono" was coming out somewhat more colorful than might be desired. The Load/Save window file list now automagically positions itself so that the filename is 'centered' in the file list region. Also, there's a new icon for executable files (in the Load/Save window) Now the 'Zoom In' rectangle is tracked until you release the mouse button. Fixed 'Timer()' function to use 'sginap()' on SGI machines. (James Nugent (james@ironbark.bcae.oz.au)) Improved Expose event handling (groups multiple exposes, and requests BackingStore on the ctrl, coledit, and image windows) (Robert Forsman (thoth@raybans.cis.ufl.edu)) YCBCR-encoded TIFF images didn't work (Bill Barabash (barabash@rachel.enet.dec.com)) If you entered a directory name and pressed 'Ok' in the load/save windows, XV would try to treat it as a plain file. (Bill Barabash (barabash@rachel.enet.dec.com)) Postscript 'previews' were generated 'inverted' (white-on-black instead of black-on-white) (Vivek Khera (khera@cs.duke.edu)) Minor memory leak in ColorDither() Configuration fix for 386's running SVR4 (Andy Michael (eesrajm@brunel.ac.uk)) Bug Fix: If you opened the ColEdit Window, clicked on 'Norm', then clicked on 'Gam' in the Intensity graph, you'd get a nice random string of uninitialized data... (Michael Pall (pall@rz.uni-karlsruhe.de)) It'll now pop up a nice, friendly "Can't CD to that directory" dialog box if you try to cd to a directory that you don't have proper permissions to read. (idea: Peder Langlo (respl@mi.uib.no)) The selection and position of the directory list (in the Load/Save window) is now remembered, instead of being cleared each time you open the window. (idea: Peder Langlo (respl@mi.uib.no)) You can now switch color editor 'presets' by typing Meta-1, Meta-2, Meta-3, or Meta-4 in any XV window. Handy if you have a couple of 'standard modifications', and you don't want to bring up the big ol' color editor window just to click a single button. Also, just to be convenient, you can also press Meta-R (or Meta-0) to Reset the color editor. (idea: Phil Richards (pgr@prg.oxford.ac.uk)) Tweaks to xv.h to make it compile without modification on an HP running HPUX 8.*, in theory anyhow. (thanks: Tony Clark (tclark@hptc.mentorg.com)) Rev: 4/28/92 (version 2.21) ------------------------------ Since XDestroyImage() seems to fail to destroy the actual image data on some systems, I've replaced all calls to XDestroyImage() with xvDestroyImage(), which explicitly kills both the image data and the image structure. Added '-close' option (and 'autoClose' boolean resource) to toggle the "automatically close all windows when you iconify the image window" behavior. By default, this behavior is turned *on*. You can now specify just a width *or* a height in the '-geometry' spec. The other dimension will be calculated to preserve the aspect ratio. Makefile.std was *not* up to date. Various prototype fixes, Imakefile changed, etc. (David Brooks (dbrooks@osf.org)) Conflict with constant 'BITS' (defined in xvgifwr.c) on some systems. (Bernd Mohr (mohr@immd7.informatik.uni-erlangen.de)) 'xwd.c' seems to have snuck into the 2.20 distribution. It has been excised. The '-expand' option didn't work with negative numbers, as it should. Also, '-e' didn't work, even though there are no other '-e*' options. (Marcel Wijkstra (wijkstra@fwi.uva.nl)) Minor AIX tweakage Some calls to rd_str() should have been rd_str_cl(), and other minor probs. (Andreas Stolcke (stolcke@icsi.berkeley.edu)) Rev: 4/24/92 (version 2.20) ----------------------------- Enhancement: In the color editor, you can now 'Set' the 'Reset' button, as well as presets 1-4. This is useful if you've like to temporarily set your 'default' settings for the remainder of the current XV session, without having to play around with 'xrdb'. For example, you might temporarily be using XV on a monitor with different color characteristics than the one you normally use. You could deal with this problem by playing with the r,g,b graphs, and then, once the image looks 'right' again, setting the 'Reset' button, so that all subsequent images will have this same modification applied to them. Enhancement: The '-wait' option works better. It now waits until the image has been fully drawn before starting the timer. Now, you're guaranteed that your images will be up at least as long as you specify with the '-wait' option (plus whatever time it takes to load and prepare the next image for display). Also, you can now specify '-wait 0' to mean 'as fast as possible'. Handy if you're doing the weather map trick described below. Enhancement: The '-visual' option seems to actually *work* now. It only 'theoretically' worked before (read: "didn't work at all"), as my X server only supports one visual, making testing impossible. Since then I've gotten my hands on a DecStation, which has an X server that supports several different 8-bit visuals. It should work with visuals of different depths, as well, but it might not. Enhancement: All places in the code that were hard-coded to use the directory "/tmp" (when creating temp files) now use the value of the environment variable TMPDIR, if defined, and "/tmp" if not. Added Feature: '-loadclear' command-line option (and 'clearOnLoad' boolean resource) lets you turn on the clearing of the image window (or root window) done whenever you load an image on a PseudoColor (or Grayscale) display. This clearing USED to be done by default, to hide the temporary 'rainbow' effect caused when colormap entries are freed and reallocated. This is no longer the case. I've decided that I find the effect vaguely entertaining (something to look at while waiting for the next image to load), and more importantly, if you have a series of images that use the same colors, you can now use XV to animate them (albeit no faster than a frame every 1-2 seconds). Ferinstance, get the satallite radar images from vmd.cso.uiuc.edu, (in the directory 'phil.515'), and run 'xv -wait 0 -wloop SA*'. Just like the evening news! Added Feature: There's now a 'compressed' checkbox in the Postscript window. When enabled, XV will generate RLE-compressed Postscript files. Also, the images will be written as 8-bit data with a colormap. The practical upshot is that color PS files can now be *much* smaller. (Resource name: 'pscompress', type: boolean) One note: Compressed images may take considerably longer to print than uncompressed images. As an example, the default XV pic took (on a LaserWriter II NTX): Color, Compressed: (87k) 4:00 (4 minutes, not hours!) Color, Uncompressed: (391k) 2:30 Gray, Compressed: (85k) 1:40 Gray, Uncompressed: (130k) :20 The lesson is: unless you're printing to a color printer, you're probably best off sending uncompressed grayscale Postscript. Added Feature: whizzo new 'Grab' command. Lets you grab any rectangular section of the screen into XV. To use, click on the Grab button (or type ctrl-G). The display will beep, and the cursor will change. Press the LEFT mouse button and draw a rectangle, or press the RIGHT mouse button to abort the grab. The grabbed portion of screen will be automatically loaded into XV for manipulation. Alternately, you can click the MIDDLE mouse button on a window. The window (and its frame) will be snarfed into XV. Used in conjunction with XV's extensive color manipulation thingys, you can now figure out the 'perfect' colors for your xterms, icons, xclocks, or any other thing you can get up on your X display. Finally, a replacement for the program 'pikapix' from the ol' X10 days! For what it's worth, the Grab command doesn't work on Mac's running MacX in a 'rootless' mode, for semi-obvious reasons. (idea from: Arvind Sabharwal (arvind@brutus.ct.gmr.com)) Added Feature: XV can now read RLE files (Utah Raster Toolkit format). Added Feature: 'HistEQ' button in Color Editor window. Performs intensity histogram equalization on the CURRENTLY VIEWED PORTION OF THE IMAGE. Occurs between the colormap editor and the HSV modifier (in terms of the color editor data flow). This command has the general effect of balancing the overall contrast of the image (increasing contrast on washed-out images, and decreasing the contrast on overly-sharp images, so to speak...) It works best on grayscale images. The keyboard equivalent is 'H' (capital 'h'). Change: The 'MaxCn' (maximum contrast) button has been changed to a 'Norm' (normalize) button. It expands the intensity range of an image so that the darkest pixels will be have an intensity of '0' and the brightest pixels will have an intensity of '255'. This is *almost*, but not quite, what it used to do. The keyboard equivalent is now 'N' (capital 'n'). Added Feature: You can now Load files from a pipe by having the first character in the Load box filename thingy be a '!' (or a '|'). For example, you can Load "! bggen -s 400 -w 400 0 0 255". XV will run the specified command, saving its standard output to a file, and then load this file. (The stdout produced must still be in one of the recognized image formats.) You could use this get an image from a video digitizer or scanner, assuming you have the appropriate filter program written. You can pipe multiple commands together, as well. For example, you can Load "! xwd | xwdtopnm" to take a snapshot of a window and display it, though given the new Grab command, this isn't such a great example... (idea: Marty Leisner (leisner@eso.mc.xerox.com)) Change: The 'Save to pipe' feature is now specified by starting the filename with *either* a '!' or a '|' character, to be consistent with the 'Load from pipe' command. Added Feature: exciting new 'zoom' and 'unzoom' commands! To use them, hold down the 'control' key, and move the mouse into the image window. A Left click will zoom in by a factor of two, centered on the mouse position. A right click will zoom out by a factor of two (if possible), centered around the currently displayed subimage. These commands can easily replace the Crop/UnCrop commands for casual users. (idea from: Dan Zehme (dan@mordor.webo.dg.com)) Added Feature: 'include preview' check box added to postscript dialog box. Let's you write ps files without the preview, to save some space. (resource name: 'pspreview', type boolean) Added Feature: all xv windows are closed if you iconify the image window (or the controls window if you're in a 'root' display mode). All closed windows will be reopened when you deiconify the image window (or controls window). One misfeature: only the 'main' xv windows (image, controls, info and color editor) will retain their screen position. The various 'pop-up' windows will not. To be dealt with at a later time. Enhancement: Support for 4" x 5" and 35mm postscript film recorders added Enhancement: Increased size of control window to make room for '24-bit conversion' menu button. List now displays 11 names instead of 9. Enhancement: Hooked in the new version (3.0) of the TIFF library. Bug fix: more bug fixes to the 'slow' 24-to-8 algorithm Bug fix: if loading a truncated interlaced GIF file (not that I recommend it), XV will no longer clear from the 'current line' to the bottom of the image, which would overwrite valid image data (Dean Elhard (elhard@system-m.za05.bull.com)) Bug fix: memory leak in the '-slow24' code discovered and fixed. (Dean Elhard (elhard@system-m.za05.bull.com)) Rev: 3/17/92 (version 2.12) ----------------------------- Added Feature: 'save at normal size' checkbox in save window. When turned on, images will be saved at their normal, unexpanded (and *unshrunk*) size, subject to the current cropping and rotation. Note: The Dither and Smooth commands operate on expanded images. (In fact running Smooth on a 1:1 image should have no effect.) AS SUCH, images saved at 'normal size' will be saved 'Raw'. (Resource name: saveNormal type: boolean) Added Feature: You can now change 24-to-8-bit algorithms (ie, quick24, slow24, best24) while running the program (via a pop-up menu button). Added Feature: '-nolimits' option (and 'nolimits' resource). If set, there are no limits on the size of the image (beyond the X-imposed 64K by 64K). WARNING: Be *very* careful when using this option and playing with cropping, as it's dangerously easy to accidentally generate a HUGE image, and crash XV, the host machine, your X server, or all three. USE AT YOUR OWN RISK! (Tero Kivinen (kivinen@joker.cs.hut.fi)) Enhancement: X images (on 8-bit displays) are now generated so that scanlines are a multiple of 32 bits long. This should avoid problems with certain broken X libraries and/or servers that weren't doing the image format translation correctly. (Jeff Coffler (coffler@jeck.amherst.nh.us)) Enhancement: Changed scrollbar behavior: Now, when you drag the indicator, the list that the scrollbar controls is updated while you drag. Enhancement: when choosing a new directory (in the save menu), xv now remembers the 'suggested' filename to save under, instead of clearing the text entry doodad. Enhancement: Upped maximum number of files in control window list (and therefore, on the command line) to 4096 (from 1024). Enhancement: Hooked in the new version (3.0) of the JPEG libraries. Most relevant change: when loading JPEG files ONLY, the 'quick' and 'slow' 24-to-8 algorithms are now performed by the JPEG software. They seem to be every bit as good or better than the XV algorithms. The 'best' algorithm still falls through to using the ppmquant-based algorithm in XV. (Tom Lane (Tom.Lane@g.gp.cs.cmu.edu)) Change: by default, the 'keepAround' flag is now set to 'true'. Now, xv will hang around if you delete the last file in the controls list. (-keeparound toggles this flag on and off, and the keepAround resource still behaves the same way.) Bug fix: Compound resources (eg 'xv.preset1.satval') weren't getting properly set on certain systems. (Dean Elhard (elhard@system-m.za05.bull.com)) Bug fix: XV will now (potentially) run 'better' under DXWM. Bug fix: 'Reduced Color' images weren't saving as such in either the PPM or TIFF formats. (They won't in JPEG, either, but trust me, you don't want to save reduced color images in the JPEG format...) Bug Fix: numerical inaccuracies in HSV modification part of color editor were causing certain colors to be lost (eg, an input of (254,254,254) was coming out (253,253,253), even when everything was set up to do a 1:1 mapping.) Bug Fix: minor memory leak in KillOldRootInfo() fixed. Rev: 3/4/92 (version 2.11) ----------------------------- Problems with Imakefile fixed. (David Brooks (dbrooks@osf.org)) Problems with SetISTR() function declaration fixed. (David Brooks (dbrooks@osf.org)) Compiler noise shut up (Phil Karlton (karlton@fudge.asd.sgi.com)) Rev: 2/26/92 (version 2.10) ----------------------------- Generate updated documentation, this time on a Mac running System 7. The generated postscript *may* be cleaner. I hope... Incorporated Anthony Datri's PDS/VICAR file reading code Added '-rv' option (and 'reverse' resource). Displays 'negative' images (white becomes black, black becomes white, and colors do interesting things). Bug fix: shifted arrow keys (for adjusting cropping rectangle size) didn't work on Sparcstations running OpenWindows. Rev: 2/22/92 (version 2.06) ----------------------------- Added whizzo new colormap editing feature. Click on a color cell with the left mouse button. Now click on another color cell with the middle mouse button. All colorcells in between these two colorcells will be interpolated between these two colors. For example, view the 'default' image by just running 'xv' without any options. Open the color editor window, left-click on the first colorcell, and turn it 'red'. Left-click on the 64th colorcell (the rightmost cell on the last complete line of the colorcell grid), and turn this colorcell yellow. Now, middle click on the first colorcell. Voila! Niftily interpolated reddish yellows. Neato! Added 'reload on signal' feature. If you send the XV process a 'QUIT' signal ('kill -QUIT ', or 'kill -3 ' on most systems), the program will reload the currently selected file. (The one that is currently highlighted in the xv controls window filename list.) This behavior is exactly the same as hitting '' in the xv controls window. If XV is currently in a state where hitting '' in the controls window won't load an image (ie, some pop-up dialog box is grabbing all such events), then sending this signal won't work either. Note: it also won't work if the current file was read from Changed way 'uncrop' works to limit 'drifting' of windows when cropping and uncropping. Also, puts window back where it belongs when you load a new image. When cropping, Raw/Dithered/Smooth status of image will remain the same. When uncropping, however, it will revert to 'raw', given how long the dither/smooth operations can take on a potentially large image. Now tracks x,y coordinates of handles in the 'graph' windows of the color editor window, for precise placement. Also, you can now move a handle through all 256 x and y positions, not just the 'even' values. Bug fix to 24-to-8 code. (Would crash on a 1-bit display.) Rev: 2/13/92 (version 2.04) ----------------------------- tracked pixel values strings are now put in the 'cut buffer' with a trailing '\n' character '-black' and '-white' options now affect how all 1-bit b/w images are displayed, no longer just used in conjunction with '-ncols 0' Added command line options '-quick24', '-slow24', and '-best24' to select different 24-to-8 conversion algorithms. 'slow24' is the default. (Also, 'quick24' and 'best24' boolean resources) Added the 'ppmquant' 24-to-8 bit algorithm ('-best24' option). Note that this algorithm is *much* slower than the so-called '-slow24' algorithm. The major difference is that this algorithm will produce good-looking undithered images, whereas the 'slow24' algorithm dithers. Fixed various bugs in the '-slow24' 24-to-8 bit algorithm. Added '-cecmap' option (and 'ceditColorMap' resource) to specify whether or not to install the image's colormap in the color editor window TIFF i/o routines added (Sam Leffler (sam@sgi.com)) Added a 'browse' button in the Load window. Lets you change the 'browse mode' interactively, while the program is running. (See '-browse' option below.) Added 'autoApply', 'displayMods' and 'autoReset' resources to control initial settings of respective checkboxes in the color editor window. Program is less likely to gratuitously clear the image/root window if you are on a non-PseudoColor/GrayScale display increased size of 'OutCode[]' array in gif reader. (Rolf Mayer (rz90@rz.uni-karlsruhe.de)) load/save window used to crash if you had a directory with 'too many' files (Craig McGregor (CRAIG@csdvax.csd.unsw.EDU.AU)) Rev: 1/24/92 (version 2.01) ----------------------------- Added '-crop' option (and 'autoCrop' resource) to do the 'autocrop' command automatically whenever an image is loaded. Added '-browse' option (and browseMode resource). Keeps the Load window from being closed after succesfully loading a file. Added '-nostat' option (and 'nostat' resource) to speed up Load/Save windows. Prevents the program from doing 'stat()' calls when you change directories. (Useful for systems with a lot of remote files, where doing the stat() calls takes 'too long') Downside: it won't be able to mark directories with a 'folder' icon, as it won't *know* that they're directories. added '-noresetroot' option (and 'resetroot' resource). Let you turn off the 'clear the root when switching from a root mode back to window mode in the display modes menu' behavior. Useful for checking your cropping, if you're working on a 'mirrored' root background (or something) (David Elliot (dce@smsc.sony.com)) added a 'rescan' button in the Load and Save windows. Rescans the current directory. fixed up GIF89 parsing somewhat. fixed bugs in xvAllocColor() that would show up if running XV on a TrueColor display. PostScript files written in B/W Stipple weren't correct (Peter Glassenbury (pete@cosc.canterbury.ac.nz)) SortColormap() function in xvcolor.c sped up (Dave Jones (jonesd@kcgl1.eng.ohio-state.edu)) fixed problem with 'cropping rectangle' not being drawn correctly. Loads current directory only when opening the Load/Save windows, not when the program starts up. This is to improve startup time. Reloads current directory when you do a 'Delete file' command, just in case you deleted a file in the current directory. 'hints' handling improved. When controls/info/coledit windows are closed and reopened, they reappear where they *were*, not where the original geometry spec put them. FREAD and FWRITE macros in jinclude.h renamed, to avoid conflicts. problems with 'XLookupString()' on VMS and AIX fixed (Dave Jones (jonesd@kcgl1.eng.ohio-state.edu)) patches for Sequent machines (Scott Erickson (sources@sherlock.ics.uci.edu)) Added 'fsQuick' code. Dithers (on 1-bit displays) 2 to 3 times faster than the old code. Looks about as good. (David B. Rosen (rosen@cns.bu.edu)) code for 2-bit displays (so to speak :-) added (Marc Kossa (M.Kossa@frec.bull.fr)) bug in parsing '-dither'/'-display' fixed (Nigel Pearson (nigel@socs.uts.edu.au)) Fixed crash if you hit 'return' while xv was running with no file names. fixed potential memory leak on systems where XDestroyImage() doesn't free the image data, only the structure. fixed '-fixed' option fixed bogus Macintosh prolog file in PS documentation. 8-bit characters in PS documentation turned into properly-escaped 7-bit characters. (Reg Clemens (clemens@plk.af.mil)) minor mods for RS6000 (Tom McConnel (tmcconne@sedona.intel.com)) new (still unsupported) version of VICAR/PDS file handler added to unsupt/ directory (Anthony Datri (datri@concave.convex.com) fixed segmentation fault in openPic() (Jimmy Aitken (jimmy@pyra.co.uk)) fixes for Pyramid BSD machines (Jimmy Aitken (jimmy@pyra.co.uk)) fixed 'tolower' bug in lower_str function (Rich Thomson (rthomson@dsd.es.com)) patches for AUX systems some ANSI C complaints quieted (Jamie Zawinski (jwz@lucid.com)) fixed WM_DELETE property problems (Jamie Zawinski (jwz@lucid.com)) Changed occurrences of string 'basename' to 'basefname' to avoid conflict on certain systems, and fixed a bug in rd_int() (David Elliot (dce@smsc.sony.com)) fixed bug that could cause window to move bizarrely on a 'Max Size' command make 'clean' dependancy added to Imakefile (Rainer Klute (klute@irb.informatik.uni-dortmund.de)) Rev: 1/2/92 (version 2.00) ----------------------------- *** SUN Rasterfile support (Dave Heath (heath@cs.jhu.edu)) fixed unclosed comment in xv.h (Paul Close (pdc@sgi.com)) fixed infinite loop in Imakefile (Kjetil Jorgensen (jorgens@lise.unit.no) fixed problems in Imakefile (bitmaps.h wasn't being rebuilt) (Jonathan Kamens (jik@pit-manager.mit.edu)) additional bug fixes/workarounds for 24/32-bit TrueColor displays (Dave Gregorich (dtg@csula-ps.calstatela.edu)) include string.h or strings.h based on 'SYSV' flag (Kevin Brown (brown@hpbsm15.boi.hp.com)) bogus command line parsing ('-autogamma' wouldn't work) (Doug Washburn (washburn@hpmpea2.cup.hp.com)) fixed 4-bit X code to work on MSBFirst machines (Stefan Esser (se@ikp.Uni-Koeln.DE)) mods for HPUX 7.0 (Jan D. (jhd@irfu.se)) added window classes 'XVroot', 'XVcontrols', 'XVdir', 'XVinfo', and 'XVcedit', so Motif users can do things like this: Mwm*XVroot*clientDecoration: none Mwm*XVcontrols*clientDecoration: -resizeh Mwm*XVdir*clientDecoration: -resizeh -maximize Mwm*XVcedit*clientDecoration: -resizeh -maximize Mwm*XVinfo*clientDecoration: -resizeh -maximize Also, WM_DELETE_WINDOW is now set up in the WM_PROTOCOLS property, allowing the 'close' menu selection under MWM to close an XV window without terminating the application. (Jan D. (jhd@irfu.se)) slow 24-to-8 conversion was moving the image down 1 scan-line (Satoshi Asami (asami@is.s.u-tokyo.ac.jp)) mods for MIPS machines (David Boulware (dgb@landau.phys.washington.edu)) Ability to LOAD pictures that weren't specified on the command line fixed bug in CheckForConfig() twm workaround from patchlevel 2 now only turned on if '-twmkludge' option is specified. Was causing problems on OpenLook 2.0 systems directories and symbolic links are now sorted together at the top of the 'xv directory' list fixed crashes when 'AutoCropping' in conjunction with '-root' option file format/color buttons in Directory window are now set whenever an image is loaded. (Set to the format/color of the loaded image.) clicking anywhere inside the Info box will now close it added support for up/down arrows, page up/down, home, and end keys when mouse is in control window or directory window (for operating the scrollable list thingy) changed 'Return' key binding to mean 'display currently selected picture' rather than 'Next' added binding of Tab key to 'Next' function '-wait' now waits until picture is fully up on screen before starting timer '-wloop' option added. Causes '-wait' slideshow to loop at end added 'hagan-style' tiling on the root window. '-root', '-center', and '-rpat 0' (the default) will now draw an image centered on the root window, with images going off the screen in all 4 directions (Unlike 'normal' ('-root' only) tiling, which has one image pinned in the top-left corner of the screen, and subsequent images going off the screen ONLY on the bottom and right sides) added '-maxpect' option. (An abbreviation for '-center -fixed -max') makes the image as large as possible, without changing the aspect ratio. Only relevant when used in conjunction with '-root'. (When not using '-root', both '-max' and '-maxpect' do the same thing (as large as possible without changing the aspect). When USING '-root', '-max' makes the image the size of the screen, in all likelyhood changing the aspect ratio) added '-olwm' option (and xv.olwm resource) for people using Sun's OpenLook window manager. Makes the window behave correctly when resized via any of the xv resizing commands. added new, slicker-looking icon. The old one was outside Motif's accepted range of icon sizes. SMOOTHING controls (Smooth, Dither, and Raw buttons) added added '-cursor' option (and xv.cursor resource). Allows you to pick a different cursor for the image window (instead of the default crosshair cursor) various modifications to work somewhat better with tvtwm (or other virtual window managers) Hitoshi Saji saji@is.s.u-tokyo.ac.jp Tetsuya Ikeda tetsuya@is.s.u-tokyo.ac.jp Satoshi Asami asami@is.s.u-tokyo.ac.jp fixed up some multiple-redraw bugs, for improved speed Added spiffy 'hue' and 'saturation' dials to cedit box New format for '-GAMMA' command line option and gamma resources. Fully specifies state of gamma controls, including 'lines/spline' and 'rgb/hsv' modes Improved 'undo' handling in Gamma box. Added 'reduced' color save. Used in conjunction with the '-nc' command line option. Saves the image more-or-less 'as shown', rather than "as it's supposed to be". For example, you can now save bizarrely stippled pictures by doing something like '-nc 0 -wh red -bl blue' on the command line, and then saving the image in 'reduced color'. added '-adither', '-asmooth' options (and 'xv.autoDither', 'xv.autoSmooth' resources) to automatically dither or smooth the image upon loading it. Mainly for use the case where you want XV to load an image onto the root window and go away without any user intervention. (Like you might put in a startup script.) added some X error handling so that XV doesn't blow up (ungraciously) when you're using '-root' on an X terminal that doesn't have enough memory to do a full-screen root image code reorganization: xv.c and xvmisc.c have been split into (xv.c, xvevent.c, xvroot.c) and (xvmisc.c, xvimage.c, xvcolor.c, xvsmooth.c) respectively. The files were getting annoyingly large. added colormap editing capabilities to the gamma box Colors can be edited in either HSV mode or RGB mode You are modifying the original colormap of the image, BEFORE the '-mono' or '-rv' options are applied, BEFORE any GAMMA correction is applied, and before it's determined how to get the image on the screen. As a result, it's best to edit colors when the GAMMA controls are set to 'Linear' You can select the color to be edited by clicking in the colormap area of the GAMMA box, or by clicking in the image window (in which case the color selected will match the last pixel value you displayed) Using '-rw' mode will generally speed things up, but isn't necessary. added colormap 'grouping'. Use Button3 to add/delete color cells from the current group. Hold shift key down and the image regeneration will be delayed until you let go of the shift key. (normally the image would be redrawn every time you released Button3.) This allows you you quickly group multiple pixels. added 'cut buffer' usage. Whenever you track pixel values (by clicking the left button in the image window), the last pixel values are put in the X cut buffer, so that you can paste them into your own program, an xterm window, or whatever. Useful if you're using XV to choose 'points-of-interest' to be used as input to another program. Also, if you click on the gamma values (above the graph in the gamma window), those values will be put in the cut buffer as well. (Handy for setting default values for the Gamma resources.) added a slightly-improved 'cropping' rectangle. Should show up better on some pictures. added hsv pixel display. When tracking pixel values in the image window (with the left mouse button), the values will either be displayed as R,G,B components (0-255), or as HSV components (0-359, 0-100, 0-100) This is based on the setting of the HSV/RGB switch in the Gamma box. added a 'Randomize Colors' button. (keyboard equiv: 'R'). Causes the entire colormap of the current picture to be randomized. Groupings *will* be respected, however. (ie, all pixels in a group will still have the same color, albeit a new one). For amusing effects, do some by-hand color reduction (by grouping all similar colors), then do the randomize function. added an 'Undo All' button in the Gamma box. Undoes all changes made to the image's colormap and clears all groupings. added '-hsv' and '-rgb' switches (and xv.hsvmode resource (boolean)) to allow user to set initial hsv/rgb mode. By default, program uses RGB. fixed 'shift key' bug with regards to entering filenames in dir window 'enter' in file i/o window now opens the currently selected directory fixed bugs on 1-bit displays (fish cursor didn't flap during re-ditherization, CMap wasn't properly refreshed after loading new pic) Smooth/Dither now sets 'Current Size' RButt in file i/o box. (Need to save at current size to save 'smoothed' picture.) BadAccess errors cause by XFreeColors are now ignored, as this is simply a sign of a busted X server, and happens when multiply-allocated colors are freed more than once. (like they're supposed to be) Should make '-bfc' option obsolete. Current Size RButt ripped out. (Always saves at current size) flapping fish cursor added during PBM/PGM/PPM file i/o created GRAF type MASSIVE modifications to GAMMA box Gamma box renamed 'Color Editor' box ('cedit') Added direct numeric gamma input to GRAF boxes Created HDIAL controls Changed non-range HDIAL to be a hue/saturation control Created CBUTT check boxes Added 'drag the whole range around' feature in range HDIALs Added -nopos, -fgeom, and -fmap command line options (and resources) Fixed 'crop near corner' graphics bug Fixed multiple redraw bug, with any luck. Added '-2xlimit' option and resource. Allows the image window to be larger than the screen (up to 2x). *NOT* recommended unless your WM is capable of operating windows without visible borders. (ie, you'll need some meta-mouse-button action, ala twm/uwm...) Added rudimentary GIF89 reading. (Jon Brinkmann, jvb7u@astro.Virginia.Edu) Changed ISTR_INFO to be more to Hagan's liking. (eg "320x200 GIF87. Got all 37 colors.") Fixed some probs in xvsunras.c (didn't understand RT_FORMAT_RGB, and RT_BYTE_ENCODED 8-bit rasterfiles didn't load correctly, nor did it handle odd-width 24-bit images correctly) Added POSTSCRIPT OUTPUT and PostScript Box (7/6/91) Drag the image window around on the page with the mouse. The scale controls are used for stretching. Note: if you use the arrow keys (regular and shifted), you can get precise positioning control. Added GIF89 aspect ratio handling, warning message about skipped extensions, PlainText block handling (doesn't do anything with it) Ripped out the '-fish' option and related code. Never worked right anyway. Added ability to type long strings in 'filename' field of dir box. Split 'file i/o' button into two buttons 'Load' and 'Save'. Directory box is now either a 'Load box' or a 'Save box', depending. (^L and ^S are the accelerators). Added ability to type pathnames in 'filename' field. And 'cd-ing' to different directories directly without going through pesky UI. Added 'popup' windows. (The computer seems to be on fire. ) Stretched ctrlW so that 'helvetica' font would still fit (Ultrix 4.2 doesn't include 'lucida' still...) Added 'close' (via mwm menu) handling to PostScript window and PopUp window. Added wait cursor during directory-reading (whenever you change directories) Fixed PostScript file output (to have correct comments) Added 'maxpect' button in PS window. Hooked up remaining buttons in ColEdit window (undo, redo, brite, dim, sharp, dull) Got rid of 'recolor' operations when non-visible changes made to Graf's (changes of less than '2' aren't visible due to coordinate halving) Added 'max contrast' button to gamma window Added 'C' and 'R' keyboard equivs for 'MaxCnt' and 'Reset' respectively Added 'default' picture (xvdflt.c) Added 'Flip H' and 'Flip V' buttons ('h' and 'v' keyboard equivs) Redesigned ctrl window somewhat When you 'Load' files (via the Load dialog box), the file names are stuck in the 'ctrlW' list for E-Z Re-Viewing... Added ability to 'reload' current picture (by double clicking on its entry int the ctrl window list) Added 'Delete' command. ('^D' keyboard equiv) Mods to work (better) on Apollo systems (Robert Goodwill (robert@earth.cs.jcu.edu.au)) Added support for 16-bit displays (David Elliot (dce@smsc.sony.com)) Improved 24-to-8 color compression routines (Tom Lane (Tom.Lane@g.gp.cs.cmu.edu)) Improved color selection algorithm (Tom Lane (Tom.Lane@g.gp.cs.cmu.edu)) Flag resources now accept 'on', '1', 'true', 'yes' in either u/l case (Chris Weikart (weikart@prl.dec.com)) Fixed potential overflow bug in linear interpolation code (Chris Weikart (weikart@prl.dec.com)) Added Motif-Style 3-d buttons Added 'Auto-Reset' check box in ColEdit window Optimization to ColEdit: if changing a control hasn't actually affected the 'desired colormap', don't bother applying the change Changed 'graf' controls: you can now hold down the shift key and modify them to your hearts content. The image is not actually recomputed until you let go of the shift key. Added '-hi' and '-lo' options ('highcolor' and 'lowcolor' resources) for setting the 'other' two colors on the buttons. Added '-v' option ('visual' resource) to allow the user to force XV to use a specific visual type, rather than the server default. Added gamma resources. Hooked up 'Get Resources' button (copies current gamma settings into the cut buffer) Ripped out '-tile', '-center', and '-rpat' options. Replaced them with '-rmode' option ('rootMode' resource) Added mirrored tiling and integer mirrored tiling root modes. PopUp window now pops up with the right-most button centered under the mouse, rather than in the middle of the screen. Added '^D' accellerator key (for 'Disk File') in the 'Delete What' PopUp box. Changed '-asmooth' and '-adither' to '-smooth' and '-dither', respectively. Added stricter command line argument matching. '-snausage' no longer would match the '-s' flag. Changed way '-expand' (and 'expand' resource) works. Now takes floating point number. For backwards compatibility, negative numbers are still treated as reciprocals. (ie, both '-2' and '.5' will halve the image) Created 'MBUTT' pop-up menu widget. Added 'Display Modes' popup button. Fixed bug when using '-perfect'. The XCopyColormapAndFree() function had the rather undesirable side effect of getting rid of the allocated colors used for the various windows, etc. (ie, more than the image colors) Made 'Hagan-Style' tiling (aka, Centered Tiling) much more efficient (Robert Potter (rpotter@grip.cis.upenn.edu)) Made the 'directory' listing in the load/save box use an MBUTT. Added JPEG support. (Markus Baur (s_baur@iravcl.ira.uka.de)) (and, of course, the Independent JPEG Group) Added '-keeparound' flag (and 'keepAround' resource). By default, if you 'delete' the last file remaining in the ctrl window list, the program will auto-exit. This option overrides that behavior. Ripped out '-fgeom' and '-fmap' options (and 'fileGeometry' resource). Load/Save boxes now come up wherever the mouse is. Wrote OpenOutFile() and CloseOutFile() routines to unify redundant code in 'DoSave()' and 'writePS()' Added 'piped' output. (ie, save file "| lpr") Added 'Alert' boxes (button-less PopUp's) Bug fixes when loading/saving '~' files Fixed PS output to be Encapsulated PostScript compatible Added a faked 'colorimage' procedure for grayscale PS printers. (Color postscript files will print on non-color printers, albeit in grayscale.) New Window positioning code. Should work for (nearly) all WMs. (Matthew Stier (matthew@sunpix.East.Sun.COM)) Automatically smooths images that were 'shrunk' (2x, 4x, etc...) Bug fixes to the JPEG i/o code. (Tom Lane (Tom_Lane@G.GP.CS.CMU.EDU)) Fixed problem in xv24to8.c with the Floyd-Steinberg dithering code. (Charles Hannum (mycroft@gnu.ai.mit.edu)) Modified 'Delete' behavior. Only loads an image if you deleted the currently-viewed image. Changes the suffix of the filename in the 'save window' when you change file formats. Got rid of 'Quit XV' buttons in load and save windows Added extra verbiage to JPEG save window. Dicked around some more with window positioning code. Seems to work correctly in TWM and MWM. Hopefully, it'll work in OLWM as well. Added Makefile options and xv.h #ifdefs for Encore's UMAX version of Unix System V. (Drew Watson (dwatson@encore.com)) Added '-owncmap' option (and 'ownCmap' resource) to make XV *always* use/install its own colormap. (Bill Turner (bturner@cv.hp.com)) Rev: 11/29/90 (version 1, patchlevel 3) ----------------------------- Changed 'CCOPTIONS' to 'DEFINES' in Imakefile Fixes for use with virtual root window managers (ie, tvtwm) (only cares about virtual root when using '-root' option, negative geometry's correctly handled.) (Andreas Stolcke (stolcke@ICSI.Berkeley.EDU)) Modifications for Sequent machines (no 'mem*() routines) (Daniel Pommert (daniel@ux1.cso.uiuc.edu)) Modifications to avoid bug in certain optimizers, most notably the default optimization (-O) in Sun's C compiler. (Incorrectly handles lines of the sort "*p = array[*p]") Modification to get around 'when I shift my arrow keys (to adjust the cropping rectangle), my keyboard generates numbers instead' problem (Mark Horstman (mh2620@sarek.sbc.com) Modification to allow 'xsetroot' and 'xloadimage' to cleanup any xv-displayed images in the root window, and vice-versa. (Richard Bingle (bingle@cs.purdue.edu)) Rev: 11/26/90 (version 1, patchlevel 2) ----------------------------- added workaround for 'X Protocol Errors' on broken servers (XFreeColors()) (see the '-bfc' option) fixed core dump when cropping on certain displays misc. #ifdefs for HPs fixed problem with fish cursor remaining around too long more SVR4 #ifdefs (David Elliott, dce@smsc.sony.com) fixed bug in tracking pixel values (Bob Finch, bob@gli.com) misc #ifdefs for ISC 386/ix 2.0.2 (Mark Snitily mark@zok.uucp) misc #ifdefs for AT&T machines (Eric Raymond eric@snark.thyrsus.com) misc #ifdefs for Silicon Graphics (Paul Close pdc@lunch.wpd.sgi.com) Added POSIX signal handling (Mike Patnode (mikep@sco.com)) Port to SCO UNIX/ODT (Mike Patnode (mikep@sco.com)) fixed problem with using '-max' and '-fixed' at same time (Greg Spencer greg@longs.lance.colostate.edu) modification to work with Virtual Root Windows (ala swm and tvtwm) (Bill Kucharski kucharsk@solbourne.com) the 'save-as' filename is now set to the 'current' filename Also, if you double click on 'plain' files in the directory box, it will set the 'save-as' filename accordingly. Added ability to view images centered on the root window, without any tiling. Added associated options ('-center', '-rfg', '-rbg', and '-rpat') Workaround for twm 'No title bars' bug (Steve Swales steve@bat.lle.rochester.edu) Bidirectional Rotate commands added Maxpect command added: (Maximum size, but preserve aspect ratio) AutoCrop command added: (Crops out solid borders.) Potential support for 32-bit displays. (Hasn't been tested. Don't have one.) Rev: 10/17/90 (version 1, patchlevel 1) ------------------------------ Imakefile added (David Elliot (dce@smsc.sony.com)) System V release 4 mods (David Elliot (dce@smsc.sony.com)) Bug in 'quick check' fixed (Arthur Olson (ado@elsie.nci.nih.gov)) Mods for Convex machines (Anthony Datri (datri@convex.com)) 'vprintf' module added (Jonathan Kamens (jik@pit-manager.mit.edu)) window creation bug fixed added icon fixed 'Input Focus' probs added '-w' flag to bggen various cleanups to shut up 'noisy' compilers Rev: 10/9/90 (version 1, patchlevel 0 - initial release)
