    Following on from your previous post.
    Reading bmp file to 2d array

    You read in a BMP into a 2D array of pixels.

    You modify some of those pixels in some way.

    You write out a BMP to a new file.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Go to my website and look at the Baby X resource compiler. It contains a file called bmp.c which provides functions for loading and saving .bmp files.

    Nope, looks like a 404.
