public final class ANGLEPackReverseRowOrder extends java.lang.Object
Native bindings to the ANGLE_pack_reverse_row_order extension.This extension introduces a mechanism to allow reversing the order in which image rows are written into a pack destination. This effectively allows an application to flip the results of a ReadPixels in the y direction operation without having to render upside down.
The coordinate system of OpenGL is vertically reversed in comparison to a number of other graphics systems such as native windowing APIs. Applications that perform ReadPixels may have to either render to an intermediate color buffer before calling ReadPixels or perform a flip in software after ReadPixels. In some systems the GL can perform the row reversal during ReadPixels without incurring additional cost.
