Hi there,
Just wondering if anyone knows how to probe the colour value of a pixel
in a render window? I presume it has something to do with the
'GetPixelData' function, but I don't seem to be able to get any values
back from this. I would appreciate a quick description of how to use
this function.
cheers,
Bruce Lamond
