Color depth (--depth)

Objects with this attribute

• X application
• Windows application

Usage

Description

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

The 16/8-bit and 24/8-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, Tarantella 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 multiple color depths

Use the 16/8-bit and 24/8-bit settings if you need to run 8-bit applications in a 16 or 24-bit high color X application session, for example from a CDE desktop. These settings allow you to support multiple color depths.

These settings:

• will increase the amount of memory used on the Tarantella server:
  • 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).
