'''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. |
|
