1. Negative Images
Hi,
I was wondering if anyone had a routine for finding the negative of an image?
The source will be a Jpeg.
Chers,
Alex

Isn't a negative just an complete inverse of a color image? If so,
then load it into Paint and click Image > Invert Colors...
If you want to do it code-wise, just or_bits() the color with whatever
White is (255, #FFFFFF, etc.)

Hi Greg,
Not to be nit-picking or anything, but didnt you mean xor_bits()
instead of or_bits() ?
Take care,

Probably. I usually play around with and_bits(), or_bits() and
xor_bits() until I get the desired result. :)
