| | '''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: |
