GdkVisualType

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

Values

ValueMeaning
STATIC_GRAY0

Each pixel value indexes a grayscale value directly.

GRAYSCALE1

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.

STATIC_COLOR2

Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.

PSEUDO_COLOR3

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.

TRUE_COLOR4

Each pixel value directly contains red, green, and blue components. Use Visual.getRedPixelDetails, etc, to obtain information about how the components are assembled into a pixel value.

DIRECT_COLOR5

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.
