Command line

Description

The color depth for the application. The greater the number of colors, the more memory is required on the Secure Global Desktop server and on the client device, and the more network bandwidth is used between them.

The 16/8-bit, 24/8-bit, 8/16-bit and 8/24-bit settings are only available to X applications.

Note For Windows applications, only applications running on a Windows 2003 Server can be displayed using 16 or 24-bit color. By default, a Windows 2003 Server displays applications using 16-bit color. If the color depth setting of a Windows application object is different from that of the application server, Secure Global Desktop automatically adjusts the color depth to match the server setting.

Reducing bandwith usage for X applications

To reduce network bandwidth at greater color depths for X applications, change the Color Quality setting.

Support for X applications with multiple color depths

The 16/8-bit, 24/8-bit, 8/16-bit and 8/24-bit settings allow you to support X applications with multiple color depths. For example, if you need to run an 8-bit application in a 16 or 24-bit high color X application session (such as a CDE desktop), use either the 16/8-bit or the 24/8-bit setting.

These settings:

• will increase the amount of memory used on the Secure Global Desktop server (compared to an application using a single color depth):
  • the 8/16 setting will use 200% more memory;
  • the 8/24 setting will use 400% more memory;
  • the 16/8 setting will use 50% more memory; and
  • the 24/8 setting will use 25% more memory
• will increase the amount of bandwidth used; and
• may affect performance, particularly over low bandwidth connections.

Examples

--depth 16

Sets the color depth for the application to 16-bit color (thousands of colors).
