GdkVisualType

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. Use gdk_visual_get_red_pixel_details(), etc, to obtain information about 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.
