does anybody know how to get RGB values from a declared color in gd???
I know you can create a color 'object' ($col)through sending 3 RGB values to ImageColorAllocate() or whatever, but I can't figure out the 3 RGB values OUT of an allocated color once its been made with ImageColorAt() (used to get the color of a given pixel of a loaded image)
If I could do this one thing, I could create functions in PHP to adjust hue and saturation of an image, and a million other cool things pixel by pixel...But right now I'm stuck! Please help.
