[SDL] showing bitmaps

[Ken Rogoway]

If I understand you correctly you want multiple bmps on the screen at the
same time and your screen resolution is 8bpp?  If that is the case you will
need to pre-process your bmp files so they all have a common palette.

Hello,

I have a question for all you graphics programmers out there:

Situation:
Linux OS with framebuffer device - 320x240 8bpp. Console application (no SDL
yet:() tries to draw two bitmap images pixel by pixel to the framebuffer.
The final result is that colors on first image are corrupt, when I write the
colors from second image to the framebuffer palette.

Procedure:
read bmp1
set color palette from bmp1
draw bmp1
read bmp2
set color palette from bmp2
draw bmp2

How can one display several 8 bpp BMP images on screen so that they all
retain its correct colors?


Thank you,
Hinko
