SYNOPSIS

10       #include <glitz.h>
11

DESCRIPTION

13       Glitz   is   an   OpenGL  image  compositing  library.  Glitz  provides
14       Porter/Duff compositing of images and implicit mask generation for geo‐
15       metric primitives including trapezoids, triangles, and rectangles.
16
17       The  semantics  of glitz are designed to precisely match the specifica‐
18       tion of the X Render extension. Glitz does not only implement X  Render
19       features  like component alpha and image transformations, but also sup‐
20       port for additional features like convolution filters and color  gradi‐
21       ents, which are not currently part of the X Render specification.
22
23       The  performance and capabilities of glitz are much dependent on graph‐
24       ics hardware. Glitz does not in any way handle software fall-backs when
25       graphics  hardware  is  insufficient. However, glitz will report if any
26       requested operation cannot be carried out by graphics  hardware,  hence
27       making  a  higher  level  software  layer  responsible  for appropriate
28       actions.
