/* Sampling values from RF 5371 for JPEG 2000 over RTP : https://datatracker.ietf.org/doc/rfc5371/C
RGB: standard Red, Green, Blue color space.
BGR: standard Blue, Green, Red color space.
RGBA: standard Red, Green, Blue, Alpha color space.
BGRA: standard Blue, Green, Red, Alpha color space.
YCbCr-4:4:4: standard YCbCr color space; no subsampling.
YCbCr-4:2:2: standard YCbCr color space; Cb and Cr are subsampled horizontally by 1/2.
YCbCr-4:2:0: standard YCbCr color space; Cb and Cr are subsampled horizontally and vertically by 1/2.
YCbCr-4:1:1: standard YCbCr color space; Cb and Cr are subsampled vertically by 1/4.
GRAYSCALE: basically, a single component image of just multilevels of grey.
