Glitz is an OpenGL image compositing library. 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 for 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.
|
|
|
|
Glitz can be used as a stand-alone layer above OpenGL but is also
|
|
designed to act as a backend for cairo, providing it with OpenGL
|
|
accelerated output.
