| '''OpenGL extension EXT.packed_pixels |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.EXT.packed_pixels to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension provides support for packed pixels in host memory. A |
| packed pixel is represented entirely by one unsigned byte, one |
| unsigned short, or one unsigned integer. The fields with the packed |
| pixel are not proper machine types, but the pixel as a whole is. Thus |
| the pixel storage modes, including PACK_SKIP_PIXELS, PACK_ROW_LENGTH, |
| PACK_SKIP_ROWS, PACK_IMAGE_HEIGHT_EXT, PACK_SKIP_IMAGES_EXT, |
| PACK_SWAP_BYTES, PACK_ALIGNMENT, and their unpacking counterparts all |
| work correctly with packed pixels. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/EXT/packed_pixels.txt |
