PCX or BMP 640x480x16 ... Help!

Hi I am Jimmy.

Could someone please help me...
I managed to code a unit to read a PCX (640x480x256) in.

But I need to know how to read a PCX 640X480X16 FILE
It's for my final computer study project!!
I'll give some of my source coding for the one that could give me
info.

E-mail me at Jim...@iafrica.com

Thanx
Jimmy
