I am writing a plug-in for a image viewer with the library.
The origin, LOCO library have a support for Color Transforming.
It is a pre-transforming before compressing.
So that makes images to compress deeper 3-8% than normals.
The Photoshop JPEG-LS library by LOCO supports the issues.
But opensource libraries are not support that(includes CharLS).

So I made a patch for this.

Hi kanryu,

Thanks for sharing that code with us. I will consider adding this to the library. I got the suggestion for supporting color transforms support earlier this week!

By the way: could you share with us how you are using the library?
Such as:
- typical image size
- interleave mode (planar, line, sample interleaved)
- lossless/near-lossles
