A set of values that describe the manner in which the
pixel values for a visual are converted into RGB
values for display.
GDK_VISUAL_STATIC_GRAY
Each pixel value indexes a grayscale value directly.
GDK_VISUAL_GRAYSCALE
Each pixel is an index into a color map that maps pixel
values into grayscale values. The color map can be changed by an application.
GDK_VISUAL_STATIC_COLOR
Each pixel value is an index into a predefined,
unmodifiable color map that maps pixel values into RGB values.
GDK_VISUAL_PSEUDO_COLOR
Each pixel is an index into a color map that maps
pixel values into rgb values. The color map can be changed by an application.
GDK_VISUAL_TRUE_COLOR
Each pixel value directly contains red, green,
and blue components. The red_mask,
green_mask, and
blue_mask fields of the GdkVisual
structure describe how the components are assembled into a pixel value.
GDK_VISUAL_DIRECT_COLOR
Each pixel value contains red, green, and blue
components as for GDK_VISUAL_TRUE_COLOR, but the components are mapped via a
color table into the final output table instead of being converted directly.
