OpenGL.GL.EXT.texture_sRGB_decode

OpenGL extension EXT.texture_sRGB_decode

This module customises the behaviour of the OpenGL.raw.GL.EXT.texture_sRGB_decode to provide a more Python-friendly API

Overview (from the spec)

The EXT_texture_sRGB extension (promoted to core in OpenGL 2.1) provides a texture format stored in the sRGB color space. Sampling one of these textures will always return the color value decoded into a linear color space. However, an application may wish to sample and retrieve the undecoded sRGB data from the texture and manipulate that directly.

This extension adds a Texture Parameter and Sampler Object parameter to allow sRGB textures to be read directly, without decoding.

The new parameter, TEXTURE_SRGB_DECODE_EXT controls whether the decoding happens at sample time. It only applies to textures with an internal format that is sRGB and is ignored for all other textures. This value defaults to DECODE_EXT, which indicates the texture should be decoded to linear color space.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/texture_sRGB_decode.txt
