Greetings, I am writing a graphical routine for a screen saver and need
a little advice. What I would like to do is to draw a bmp picture on
the screen pixel by pixel (in some attractive fashion). This is a Windows
screen saver and would like to be a 256 colour bmp file.

If I put the bitmap on the form as a picture how to I just turn on the
required pixels on at a time ? (this would be the prefered solution as
it would not require an external file).

If I read in an external bmp file how do I set the windows palette and
then plot the pixels ? (I presume this is done my some windows calls?)

Any advice or sample code (VB/Pascal or C would be great) anyone ?

Thanks, Simon
