Can anyone explain to me the BMP file format? I need some sort of reader to return the rgb values of each pixel so that I can use it for matrix heightmaps, alphamaps, etc. Does anyone know of a tutorial or something?

if you just want to get the colour values of each pixel
use load bitmap "filename",0 to load it to the screen
and then use point(x,y),rgbr(),rgbb() and rgbg() to extract the value, theres a very good tutorial on it for dbpro.

I have a website!!!
So go there:
