The correct title of this article is glitz. The initial letter is shown capitalized due to technical restrictions.
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. Wikipedia does not have an article with this exact name. ... Wiktionary is a multilingual, Web-based project to create a free content dictionary, available in over 150 languages. ... OpenGL (Open Graphics Library) is a standard specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). ... In computer graphics, alpha compositing is often useful to render image elements in separate passes, and then combine the resulting multiple 2D images into a single, final image in a process called compositing. ...
The semantics of glitz are designed to precisely match the specification of the X Rendering Extension. Glitz implements not only X Render features like component alpha and image transformations, but also additional features like convolution filters and color gradients, which are not currently part of the X Render specification. Xrender (aka X Rendering Extension) introduces digital image composition as the foundation of a new rendering model within the X Window System. ...
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. Cairo is a free software graphics library with multiple backends that provides a vector-based device-independent API for software developers. ...
Glitz was developed as part of a Master's thesis called "Hardware accelerated image compositing using OpenGL" by Peter Nilsson and David Reveman. David Reveman is a software developer. ...
