Well, as it often happens, i was wrong..
i looked at the idea more carefully and youre friend was right shreyas.
One of the outcomes of the xor operation is that it can be inverted easily.
yes,
if x XOR y = z
then y XOR z = x
so you can decrypt z(the encryption) to get x(the original) so long as you have y (which acts as a sort of mask).
This applied to avs.
if you were to XOR blend imageA with imageB, you would get imageC
you could then XOR blend image B with imageC and you would get youre original imageA back!!! wowee...
i didnt know that untill shreyas pointed it out.. very clever, but not very useful...
