This forum is for people who want to share ideas about using CodeWarrior development tools.
Of course, you are welcome to participate in this forum, but please stay within its intended scope. Is there some other forum to which your question relates better?
Also, you might get a better response if you offer clearer details. For what platform and version are you programming? What libraries are you using? Have you searched the web for FAQs on graphics, PNG, or framebuffer programming?
I hope this helps. And thanks for your cooperation.
