'''OpenGL extension SGIX.blend_alpha_minmax This module customises the behaviour of the OpenGL.raw.GL.SGIX.blend_alpha_minmax to provide a more Python-friendly API Overview (from the spec) Two additional blending equations are specified using the interface defined by EXT_blend_minmax. These equations are similar to the MIN_EXT and MAX_EXT blending equations, but the outcome for all four color components is determined by a comparison of just the alpha component's source and destination values. These equations are useful in image processing and advanced shading algorithms. The official definition of this extension is available here: http://www.opengl.org/registry/specs/SGIX/blend_alpha_minmax.txt ''' from OpenGL import platform, constant, arrays from OpenGL import extensions, wrapper import ctypes from OpenGL.raw.GL import _types, _glgets from OpenGL.raw.GL.SGIX.blend_alpha_minmax import * from OpenGL.raw.GL.SGIX.blend_alpha_minmax import _EXTENSION_NAME def glInitBlendAlphaMinmaxSGIX(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
