This is whats wanted for the blue channel. The red needs to be shifted 4 left, so multiply by (1024+4)*16 for red. Alpha Green Alpha and Green are already in the high bits so vpand can zero out the other bits, keeping just 2 upper bits of alpha and 8 bit green. The same multiplier could be used for Green - (1024+4) putting the 10 bit green in the lsb. Alpha would be a simple multiplier to shift it into position. It wants a gap of 10 above the green. Green is 10 bits, so there are 6 bits in the low short. 4 more are needed, so a multiplier of 4 gets the 2 bits into the upper 16 bits, and then a shift of 4 is a multiply of 16, so (4*16) = 64. Then shift the result left 10 to position the A and G channels. */ // Shuffle table for converting RAW to RGB24.
