| '''OpenGL extension OML.resample |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.OML.resample to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension enhances the resampling capabilities of the |
| OML_subsample extension. It is loosely based on the SGIX_resample |
| extension. |
| |
| When converting data from subsampled to uniform sampling, upsampling |
| may be performed by one of three methods: component replication, |
| zero fill, or adjacent neighbor averaging. |
| |
| When converting data from uniform sampling to subsampled form, |
| downsampling may be performed only by component decimation (point |
| sampling) or averaging. |
| |
| Upsampling and downsampling filters other than those defined by this |
| extension may be performed by appropriate use of convolution and |
| other pixel transfer operations. The zero fill unpacking mode is |
| included to assist applications wanting to define their own filters. |
| |
| The official definition of this extension is available here: |
