Class EXTBlendSubtract

java.lang.Object
org.lwjgl.opengl.EXTBlendSubtract

public final class EXTBlendSubtract extends Object
Native bindings to the EXT_blend_subtract extension.

Two additional blending equations are specified using the interface defined by EXT_blend_minmax. These equations are similar to the default blending equation, but produce the difference of its left and right hand sides, rather than the sum. Image differences are useful in many image processing applications.

Promoted to core in OpenGL 1.4.
