GdkVisualType
A set of values that describe the manner in which the pixel
values for a visual are converted into RGB values for display.
Value | Symbolic name | Description | | 0 | Gdk::VISUAL_STATIC_GRAY |
Each pixel value indexes a grayscale value directly.
| | 1 | 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.
| | 2 | Gdk::VISUAL_STATIC_COLOR |
Each pixel value is an index into a predefined,
unmodifiable color map that maps pixel values into RGB values.
| | 3 | 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.
| | 4 | 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 visual structure describe
how the components are assembled into a pixel value.
| | 5 | Gdk::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.
