OpenGL.GL.OML.resample

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: http://www.opengl.org/registry/specs/OML/resample.txt
