GetPixel()

Hi -

I'm currently trying to read a bmp file with a specified x,y location. I found the function GetPixel which seems to do this for me:

ColorRef GetPixel(h, x, y);

But alas I'm not clever enough to know how to use it properly. What format does it return the pixel data? is h the filename?

Sorry if this is pretty basic stuff but any help would be much appreciated.

Cheers,

HH

I guess I'd start here.
