| | '''OpenGL extension EXT.visual_info |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GLX.EXT.visual_info to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension allows the user to request a particular X visual |
| | type to be associated with a GLX visual, and allows the user |
| | to query the X visual type underlying a GLX visual. |
| | |
| | In addition, this extension provides a means to request a visual |
| | with a transparent pixel and to query whether a visual supports a |
| | transparent pixel value and the value of the transparent pixel. |
| | Note that the notion of level and transparent pixels are orthogonal as |
| | both layer 1 and layer 0 visuals may or may not have a transparent pixel |
| | value. |
| | |
| | The official definition of this extension is available here: |
