The naming scheme is a bit out of the line when compared to their usual meaning in color science. The number usually means the number of bits for each color channel. So, ARGB8 would mean 4 channels where each has 8 bits, while RGB8 would be 3 channels of 8 bits.
If I understand the code correctly, the
rgb6
andargb8
in the code store channels as Lua numbers, so doubles. I believe it would be a bit more consistent with some established conventions to drop the number and only specify the channel names.Some references:
