Palette based images store the index of the palette entry in the image
arrays (one per channel). Truecolor images have the color values
stored directly in the buffer. The format is 31bit RGBA, 8 bit for R,
G or B and 7 for the alpha. You can see the exact mask in gd.h. The
size of the buffer is width * eight * sizeof(int).

ok, I will give it a try this week or early next week.
