With your permission, I will e-mail you a program that reads a whole
bunch of bitmap recourses and displays it to the screen. If you look at
my website, it is the Set game. Each card is a separate bitmap resouse.
I will e-mail you the source code if you ask.

Hi everyone,
wouldn't it be nice if some of who have already solved the bitmap
processing problem to give us newbies a bit of help and show use
some sample code that:
1) gets the ENTIRE header
2) the BITMAP bits
3) show the BITMAP on the device.
4) differences between low res and hi res bitmaps....
the OS has been deemed as a deas OS and we're still asking for help on
how to display BITMAPS....
searching the web is no help.....
anywho, just a thought....
