There is a new image file format named BPG (
"Better Portable Graphics"), developed by Fabrice Bellard (famous for QEMU amongst other things). It supports metadata, alpha channel as well as animations. Here are some infos:
Here is the spec:
Here are a few visual comparisons of the Lena and other images:

What is with the weird coloration images?
Never mind, it seems to be an issue with my Mac Snow Leopard version of Safari. Firefox and Chrome work fine.

Vote +1 for this format.
I am very curious to see it supported in ImageMagick. Every feature of it : Lossy, lossless, alpha transparency, animation, RGB, CMYK, etc.
Regards

We found the following in the README of libbpg:
Code: Select all
5) BPG decoding library
-----------------------
BPG images can be decoded in any program with the libbpg
library.
The API is not considered stable yet so that the library is only
provided as a static one.
We won't link with the library until this has been resoled. But we could use the binary for now. I will try to see if we can add that to the Windows release before the next release. I think the unix/linux release already does that.

The current release of ImageMagick can process BPG images under Linux if the BPG binaries are installed.

That was fast!
Thnk you very much
(I assume with "current release" you mean v6.9.0-5 to be released sometime soon -- not the v6.9.0-4 released 2015-01-16?)
BTW, your last couple of dates in the ChangeLog (here:
http://www.imagemagick.org/script/changelog.php) have the wrong year: they say 2014 where 2015 should be.
