Package org.lwjgl.opengl

Class EXTBlendColor

java.lang.Object

org.lwjgl.opengl.EXTBlendColor

public class EXTBlendColor
extends Object

Native bindings to the EXT_blend_color extension.

Blending capability is extended by defining a constant color that can be included in blending equations. A typical usage is blending two RGB images. Without the constant blend factor, one image must have an alpha channel with each pixel set to the desired blend factor.

Promoted to core in OpenGL 1.4.
