I simply missed the explanation of the meaning of "*". So please ignore this.

This is not a technical requirement for the Debian package, just a general comment about the software itself (because you are also the upstream author). I would change it in the next upstream version. > About the original compression quality. I was planning the make a > comment on my site about this why i didn't implement it yet.

I'm not an export on JPEG at all, but from what I know about the general principle I would expect that certain transformation do not incur a (or only a very small) quality loss when recompressed with the same quality setting, e.g., brightness/contrast adjustments. > so we can say that we have to use higher value for > recompression than originally to get the same image quality, and this is > not so trivial.

The point why I mentioned the compression quality: I tested your software on a few of my pictures. While the contrast etc. of a few bad pictures has been clearly improved, the size of all files is now roughly twice the old size (even if there is no visible difference). I assumed that this is due to the fixed compression quality, but maybe there is a different reason. A special value "auto" or "same" for --quality would be quite handy to maintain (almost) the same quality without increased file size and/or manually adjusting the --quality value. This discussion is a bit off-topic for d-mentors. So I suggest to continue the discussion offline.
