           Summary: Thumbnails blurry (when scaling) on PowerPC platform
                    (big-endian)
           Product: digikam
           Version: 1.2.0
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: rechner at vlado-do.de


Version:           1.2.0 (using KDE 4.3.4)
Compiler:          GCC 4.4.3 
OS:                Linux
Installed from:    Debian testing/unstable Packages

This problem was already partly discussed in #224999 "Thumbnails blury after
upgrade to 1.0.0 from 0.10" (starting with comment no 24), and I suspect it
might be related to #210580 "digiKam crashes on PPC Linux when changing
thumbnail size".

The problem with digiKam 1.2.0 on my PowerPC Debian system is that thumbnails
appear extremely blurry as soon is I scale them down a little.

As described in my comments to #224999 thumbnails are always blurry when
generated in Ubuntu 10.04 on the same PowerPC computer.

I get clear, scalable thumbnails, when I compile digiKam with
"-DENABLE_THUMBS_DB=no" - but (re)-loading of thumbnails, also when I change
their size or just change a picture's rating, is a lot faster with the new
Thumbs DB method. So having this thumbnail sharpness problem fixed properly
would probably make digiKam usage a lot more convenient for me (and maybe some
others too)!
