Description Philippe 2009-01-03 01:27:11 UTC
Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    Fedora RPMs

When you do a lossless transformation like a rotation or a flip on a jpg file, the internal thumbnail is not processed to. So the thumbnail doesn't represent the image anymore.

That's not very important into digikam because this internal thumbnail is not used at all by digikam but other software using this thumbnail (gwenview, dolphin and surely others) display a wrong one.

Bug detected on a fedora 10 with digikam 0.10 beta 7

I cannot confirm that for Rotate and flip. code is here :

http://lxr.kde.org/source/extragear/graphics/kipi-plugins/jpeglossless/jpegtransform.cpp#348

The only action where Exif thumbnail is not updated is to convert to grayscale

Sound like a cache problem in konqueror, dolphin and gwenview. Please clean your ~./thumbnails after a rotation/flip and try again...
