Graphics colorspace type

• argb8888 - ARGB 32 bits per pixel, high-byte is Alpha, accessed one 32bit word at a time.
• ycbcr422p601_pl - YCbCr 4:2:2 Planar, ITU.BT-601 specifications. The data pointed to is just an array of row pointer, pointing to the Y rows, then the Cb, then Cr rows.
• ycbcr422p709_pl - YCbCr 4:2:2 Planar, ITU.BT-709 specifications. The data pointed to is just an array of row pointer, pointing to the Y rows, then the Cb, then Cr rows.
• rgb565_a5p - 16bit rgb565 + Alpha plane at end - 5 bits of the 8 being used per alpha byte.
• gry8 - 8-bit gray image, or alpha only.
• ycbcr422601_pl - YCbCr 4:2:2, ITU.BT-601 specifications. The data pointed to is just an array of row pointer, pointing to line of Y,Cb,Y,Cr bytes.
• ycbcr420nv12601_pl - YCbCr 4:2:0, ITU.BT-601 specifications. The data pointed to is just an array of row pointer, pointing to the Y rows, then the Cb,Cr rows..
• ycbcr420tm12601_pl - YCbCr 4:2:0, ITU.BT-601 specifications. The data pointed to is just an array of tiled row pointer, pointing to the Y rows, then the Cb,Cr rows..
