libtholoura

libtholoura is a text-image distortion library, which is useful for sites that want to ensure that a human (and not a bot) is viewing pages. It is optimized to produce images of strings distorted in a way that makes it impossible for an OCR to read, but humans can. The library takes a string (preferably ASCII) string and is able to dynamically produce PNG indexed images. The distortion filters are external plugins.
