Rendering RGB buffers to X drawables.

<para>
|
|
The XlibRGB set of functions is a port of the #GdkRGB library to
|
|
use plain Xlib and X drawables. You can use these functions to
|
|
render RGB buffers into drawables very quickly with high-quality
|
|
dithering.

<!-- ##### ENUM XlibRgbDither ##### -->
|
|
<para>
|
|
These values are used to specify which dithering method should be
|
|
used. <symbol>XLIB_RGB_DITHER_NONE</symbol> will use no dithering
|
|
and simply map the colors in an RGB buffer to the closest colors
|
|
that the display can provide.
|
|
<symbol>XLIB_RGB_DITHER_NORMAL</symbol> will provide dithering
|
|
only on pseudocolor displays.
|
|
<symbol>XLIB_RGB_DITHER_MAX</symbol> will provide dithering on
|
|
pseudocolor and 16-bit truecolor or “high color”
|
|
displays.
|
|
</para>
|
|
|
|
@XLIB_RGB_DITHER_NONE: Specifies no dithering.
|
|
@XLIB_RGB_DITHER_NORMAL: Specifies dithering only on pseudocolor
|
|
displays.
|
|
@XLIB_RGB_DITHER_MAX: Specifies dithering on high color displays.
