In the Color tab, you can configure a default visual, color database and other color options.
Choose Default Visual
Select a default visual which the root window of Xmanager will use.
A visual is a device-independent color system and it defines the color format and the number of colors supported by Xmanager. Xmanager supports the 6 standard visuals defined in the X Window standard: PseudoColor, StaticColor, DirectColor, TrueColor, GrayScale and StaticGray.
If the Default Visual is set to Auto Detect, Xmanager will find and set up a proper default visual for the video device. In a 256 (8 bits) colors video mode in Windows, Xmanager will set it to PseudoColor. And in a true-color (16 bits and above) video device, Xmanager will set it to TrueColor.
Most X applications works well in any type of visual. However, some old CAD programs can run only in the PseudoColor visual and you should set the default visual to PseudoColor to run those programs successfully.Automatic Color Substitution for PseudoColor
Substitutes a requested color for a similar one in PseudoColor.
In PseudoColor visual, there are only 256 colors for all X applications and sometimes an application may fail to run due to a lack of color cells. This option allows the application to work well even when all the color cells are already allocated to other applications.Preserve System Colors (20 Colors)
Preserves 20 system colors for Windows applications in PseudoColor visual.
In a 256 colors video mode, MS Windows uses 20 system colors for title bar, window border, icons, and so on. Some X applications may use the entire palette of 256 colors in order to display correct colors. In this situation, the colors of the Windows background and icons will flash. You can prevent this by selecting this option.Exact StoreColor for PseudoColor
Processes the StoreColor request exactly as defined in an X protocol standard.
When Windows is in a true-color video mode, the StoreColor request for a PseudoColor visual may affect the overall performance of Xmanager.Reverse RGB Order for TrueColor
Sets the Red, Green, and Blue value of a color pixel in reverse order.By default, the Blue bits are the least significant bits in the TrueColor visual. If you select this option, the Red bits becomes the least significant bits. It is useful when an X application requires a specific format for the RGB bits.Filename
Shows the color database file. A color database maps red, green, and blue values to a readable color name.Change
