As with the CYMK extension, conversion to RGBA takes place immediately following the unpack pixel store, and preceding the pack pixel store operations, and is only available on transfers to and from memory. The algorithms that convert between YCRCB and RGBA are "black-box" in nature, and left undefined by the extension, however it is recommended that conversion comply with the CCIR standard. This extension specifies the format of a pixel rectangle independent of component subsampling. Component subsampling is specified using a separate extension. Two new formats are added, YCRCB_SGIX and YCRCBA_SGIX. YCRCB_SGIX is defined as a 3 component format representing the Cb, Y, and Cr values per pixel. YCRCBA_SGIX is defined as a 4 component format representing Cb, Y, Cr, and A values per pixel. As with the CMYK extension, this extension doesn't preclude the possibility of other higher quality conversion methods.
