--- Comment #36 from Gilles Caulier <caulier.gilles at gmail.com> ---
Thanks Christoph for this benchmark.

>From my side, i have experimented some format. To compress image the best ratio
will be given by Wavelets algorithm in lossless :

- PGF : need to be improved around OpenMP support. Good candidate (GPL)
- Jasper : JPEG 2000 : good but very time consuming due to floating
computation. Not optimized and now, not maintained (GPL). Don't use...
- OpenJPEG : another JPEG 2000 implementation. Very well maintained, but not
yet optimized. In progress. (GPL).
- WebP : from Google, to replace JPEG on web. fast and Open-Source like
compatible, but patents still active ?
- JPEG_XR : from Microsoft. fast and optimized, but not open source compatible.
Re-usable only. 20 active patents... Note that it's have been selected by "JPEG
organization" to replace current JPEG in digital still cameras. The war is open
(:=)))... In all case, to ignore here...
