OpenGL.GL.EXT.blend_logic_op
OpenGL extension EXT.blend_logic_op
This module customises the behaviour of the
OpenGL.raw.GL.EXT.blend_logic_op to provide a more
Python-friendly API
Overview (from the spec)
A single additional blending equation is specified using the interface
defined by EXT_blend_minmax. This equation is a simple logical
combination of the source and destination colors, where the specific
logical operation is as specified by LogicOp. While only the XOR
operation may find wide application, the generality of full logical
operations is allowed.
The official definition of this extension is available here:
