| | '''OpenGL extension EXT.abgr |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.EXT.abgr to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | EXT_abgr extends the list of host-memory color formats. Specifically, |
| | it provides a reverse-order alternative to image format RGBA. The ABGR |
| | component order matches the cpack Iris GL format on big-endian machines. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/EXT/abgr.txt |
