Enumeration Type Documentation

enum VisualType
 

A set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display.

Enumeration values:
VISUAL_STATIC_GRAY  Each pixel value indexes a grayscale value directly.
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).
VISUAL_STATIC_COLOR  Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.
VISUAL_PSUEDO_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).
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).
VISUAL_DIRECT_COLOR  Each pixel value contains red, green, and blue components as for GDK_TRUE_COLOR, but the components are mapped via a color table into the final output table instead of being converted directly.
