Assuming that your image file is a bitmap, you can load it into a memory DC and draw onto it. Once ytou've update the DC, you can save it by using the method mentioned in this article (http://www.codeguru.com/cpp/g-m/bitmap/article.php/c1697/). For more info on working with image files, consult the bitmaps and palettes (http://www.codeguru.com/cpp/g-m/bitmap/) section on CodeGuru.

You would need to convert it to a bitmap first. Something like this (http://www.codeguru.com/cpp/g-m/bitmap/article.php/c4935/), or, this (http://www.paintlib.de/paintlib/) should help.
