Using visual classes
A visual class (or visual) is the X Window System™ terminology
to describe the characteristics of a display. X defines the visual
classes listed in this table.
Static classes do not support the use of a modifiable colormap,
but the corresponding dynamic classes do.
PseudoColor
is the most common visual type. Some
applications run only on displays with a
PseudoColor
default visual class. When the Md5/DFP board is connected
to a grayscale display, you can configure it to emulate
PseudoColor
for applications by invoking the X Window
System with
PseudoColor
as the default visual class.
Static Class Dynamic Class
