LibXMI is a 2D graphics library. It supports a set of more complex 2D drawing functions than the base LibGGI API does: polygons, arcs, styled drawing/filling, logical sub-visual regions and per-pixel shaders. The API is loosely based on Xlib. New: Accelerated X/Xlib display targets from Christoph. Package is available in CVS. LibGCP is a generic color and palette management extension. It supports conversion between different color spaces such as RGBA, YUV, HSV and CMYK. Furthermore it supports a generic color-blending, which can also be used for transluency effects.

Somebody for the details? .
