GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It has many capabilities. It can ... [More] be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X. [Less]

I wanted to enlarge a sprite that I found at www.spriters-resource.com into something that would look good when enlarged. Basically this code does the following: Fills the background with ... [More] transparency. I assume that the image given has the background around it and that some of that background at 0, 0 (top-left). Antialiases the edges. Scales the image 3 times with cubic interpolation. Runs the cartoon filter to get the edges out. Runs a sharpening filter. Runs the cartoon filter again with different parameters. Adds a dropshadow (as a separate undo). Before: After: Before 8x: After 2.6x: As a comparison, this is the normal gimp scaling: Linear: Cubic: And uh, Sinc (Lanczos3): You may be more interested in the code which breaks each step into a separate function.
