5 Rendering RGB buffers to X drawables.
7 <!-- ##### SECTION Long_Description ##### -->
9 The XlibRGB set of functions is a port of the #GdkRGB library to
10 use plain Xlib and X drawables. You can use these functions to
11 render RGB buffers into drawables very quickly with high-quality

36 These values are used to specify which dithering method should be
37 used. <symbol>XLIB_RGB_DITHER_NONE</symbol> will use no dithering
38 and simply map the colors in an RGB buffer to the closest colors
39 that the display can provide.
40 <symbol>XLIB_RGB_DITHER_NORMAL</symbol> will provide dithering
41 only on pseudocolor displays.
42 <symbol>XLIB_RGB_DITHER_MAX</symbol> will provide dithering on
43 pseudocolor and 16-bit truecolor or “high color”
47 @XLIB_RGB_DITHER_NONE: Specifies no dithering.
48 @XLIB_RGB_DITHER_NORMAL: Specifies dithering only on pseudocolor
50 @XLIB_RGB_DITHER_MAX: Specifies dithering on high color displays.
