Image Data Manipulation

[Ray Horsley]

Hi ya'all,


I've got a bunch of pictures, JPEG files actually, and they're nothing but
black figures on a blue background.  I want to display them without the blue
background.  Does anybody know how to manipulate the imageData property (or
any other way of doing this) to turn all the blue pixels, which are
0,255,25, into white ones, 255,255,255, without touching the black pixels?

Thanks!
