Hi All,

I have been following an OpenGL book which has its examples in cpp, but  
using haskell instead. I have a problem when trying to read a bitmap, I  
haven't managed to render the file to the buffer, I did a little parser  
based on the one in RWH for the bmp file, and apparently everything seems  
to work well, but when I call drawPixels I don't get a clear image. The  
code that I'm using is here :

What am I doing wrong ?

Thanks in advance for any help.
