           Summary: JPEG Rotations: Give a warning when doing Lossy
                    rotations (and offer to do lossless when applicable)
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: ari.reads gmail com


Version:            (using KDE KDE 3.5.5)
Installed from:    Compiled From Sources
OS:                Linux

I'm using Digikam 0.9.0 RC2. There are multiple ways to do image rotations: from the Album GUI, from the Editor (two entries in the menu), possibly more. (not counting free rotation, which is always lossy for jpeg)

I heard one of kipilugins does lossless rotations. I have compiled and installed kipiplugins SVN, but as a newbie user, I have no idea when (and if) this kipiplugin is being used when I rotate the image inside digikam.

I'd like Digikam to clearly tell me, when I rotate a jpeg, if the rotation is Lossy or Lossless. And of course I'd prefer it to do lossless whenever possible.

GThumb tells me this (I'm using Edgy official version), when chose rotate and select the angle, the dialog clearly tells me my rotation is lossless. So for now I am using GThumb to do rotations of 45degree multiples, because I am not sure what DigiKam is doing, which is cumbersome.

Thanks!
