           Summary: JPEG lossless cropping support
           Product: kipiplugins
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: JPEGLossLess
        AssignedTo: kde-imaging at kde.org
        ReportedBy: knizek at volny.cz


Version:            (using KDE 4.2.4)
OS:                Linux

It would be nice if JPEG Lossless plugin allowed also for cropping of JPEG
images.

I can do that with external GUI tool now (MaPiVi), but it would be easier to
have it inside of digiKam to simplify the workflow.

P.S. I am aware about the discussion in mailing list
http://mail.kde.org/pipermail/digikam-devel/2006-January/002929.html more than
two years ago and the limitation to block size.

My view is that lossless cropping is still useful: point-n-shoot cameras store
images in JPEG and I use quite often (cca 90 %) the JPEGs embedded in raw files
without any editing other than rotation and cropping.
Archiving those images in PNG would lead to significant increase of storage
requirements without other benefits and lossy re-compression leads to
unneccessary quality deterioration.
