| | '''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: |
