Convert ARGB to GRGB Converts a 4-plane char ARGB (alpha, red, green, blue) matrix into a 4-plane char GRGB (green left, red, green right, blue) matrix. Alpha channel is lost and horizontal dimension is halved to support this half red and blue chroma, macro pixel output format. The GRGB format is typically useful for conserving memory and/or bandwidth for continuous tone images with less expense than colorspace conversion.
