Glitz provides +Porter/Duff compositing of images and implicit mask generation for +geometric primitives including trapezoids, triangles, and rectangles. + +The semantics of glitz are designed to precisely match the +specification of the X Render extension. Glitz does not only implement +X Render features like component alpha and image transformations, but +also support additional features like convolution filters and color +gradients, which are not currently part of the X Render specification. + +The performance and capabilities of glitz are much dependent on +graphics hardware. Glitz does not in any way handle software +fall-backs when graphics hardware is insufficient. However, glitz +will report if any requested operation cannot be carried out by +graphics hardware, hence making a higher level software layer +responsible for appropriate actions. + +David Reveman +c99drn@cs.umu.se |
