Package org.lwjgl.opengl

Class EXT422Pixels

java.lang.Object
org.lwjgl.opengl.EXT422Pixels
public final class EXT422Pixels extends Object
Native bindings to the EXT_422_pixels extension.

This extension provides support for converting 422 pixels in host memory to 444 pixels as part of the pixel storage operation.

The pixel unpack storage operation treats a 422 pixel as a 2 element format where the first element is C (chrominance) and the second element is L (luminance). Luminance is present on all pixels; a full chrominance value requires two pixels.

The pixel pack storage operation converts RGB to a 422 pixel defined as a 2 element format where the first element stored is C (chrominance) and the second element stored is L (luminance). Luminance is present on all pixels; a full chrominance value requires two pixels.

Both averaging and non-averaging is supported for green and blue assignments for pack and unpack operations.
