jit.op @op ~

~ is the bitwise complement operator meaning that it will take 255 and make it 0 or for the 8-bit color value 00011100 it will produce 11100011.

Yes, that's probably the fastest, but just for reference of other ways to handle color processing check out the following.

or jit.op @op !- @val 1. or jit.scalebias @bias 1. @scale -1. or jit.charmap

Thanks Wes for the quick reply, knew it would be something straight forward!

Cheers also Joshua for the pointers. I've got a deadline in a few weeks, and am on a steep learning curve with this stuff...expect a few more newb questions in the near future! ;-)
