Iterated Function System (IFS)

This IFS plugin does exactly what it says - applies an iterated function system over an image, finitely, making it fractal-like. Since images are worth a thousand words:

The above image was created from this one:

Then, by navigating to Filters, Misc, IFS, we get the following dialog:

Increasing the number of iterations, while taking more processing time, does make images pretty close to real fractals, and we still see small Wilber's when zooming in:

Features:

• Choose from many IFS's, including Sierpinsky Triangle, Pythagoras Tree, Hex Flake, Cantor Dust, and more;
• Option to enable or disable supersampling (makes resized images nicer);
• Modifiable number of iterations (and of course, you can re-apply the filter for some more iterations);
• Combinable fractals: run the plugin with a IFS for a few iterations, and then again with another IFS;
• Choose target image size so that if you want a big image, calculations will be made to optimize the image quality.

I had originally planned many more features for the plug-in (such as a preview and more IFS's to choose from), but honestly I grew bored of programming it, so there it is. There are probably a few bugs (notably, the target size is always an estimation and is sometimes plainly incorrect, for example when used with the Pythagoras Tree IFS), and there are a few console warnings I couldn't get rid of. However, it is still very much usable.

Included as attachments:

• IFS.c - C source code (custom license is basically: use as you please but give credit)
• IFS.tar.gz - Linux binary, compiled on Ubuntu
• IFS.zip - Windows binary, just extract to your GIMP plug-ins directory to install.

Thanks for reading! :)
