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 |
| Â Â 0 | Gdk::VISUAL_STATIC_GRAY | Each pixel value indexes a grayscale value directly. |
| Â Â 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. |
| Â Â 2 | Gdk::VISUAL_STATIC_COLOR | Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values. |
| Â Â 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. |
| Â Â 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. |
| Â Â 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. |
