simple way of generating shapes

Question

I want to generate shapes like the one following (image file e.g. PNG):

I'm looking for a c / c++ library which will allow me to realize the following algorithm:

The basic algorithm would be:

1. Make circle
2. Partition Circle randomly
3. Fill in one segement
4. Twirl whole shape (see link)
5. Save Image as PNG

I will accept the first answer which lists and links one library or more which is will enable me to implement the above algorithm with ease. The library should be light weight if possible.

Answer 1

The 'easiest' solution I can think of is to use the GraphicsMagick library - specifically, the Magick++ API. With a Magick::Image, you can use Drawable objects, flood-fills, and even a Image::swirl method. Saving as a PNG can be as simple as a call to Image::write("filename.png")
