[comp.graphics] VGA Graphics Help

Hi,  I've got another question...

I have written a program that creates an image in VGA Hi res mode and then
save the bitmap to a disk...

Now later on before I re-load the image,  I change the color palette.

I would assume that this would automatically change the colors when re-loading
the previously created bitmap..  But it doesn't...

Any help would be appreciated..

  I am not *that* knoledgable on this subject, but I would assume that
the bitmap image also stores the pallete information also. Not that there
is some type of header, but that each "pixel" representation also holds it's
own color characteristics, regardless of the current pallete during
load time.
