How it works

The algorithm

The format

Problems

• The quality is pretty bad and the size of the file is not that small. By choosing an accuracy tolerance of 2.5 or lower the ipf file might be greater then an lossless compressed PNG file which is pretty bad.
• The spereate compression of the color channels does not work well near color gradients. (fixed in v0.2)
