How to read/write into the external bmp or any pictures format / pixel?

Previous topic - Next topic



This is something I posted here a while back. It takes an image, loads it into memory, resizes it based on screen size and then saves it back as a new image. It's better than a straight sprite grab because it retains all the alpha values so full transparency settings are kept.

It manipulates an image completely (by removing pixels from it) so you should be able to change the code for what you want to do.
