Andi, Marcel,

Sound like releavant of thumbs DB...

Note: others suggestion : I thinking to strap definitively JPEGLossLess
kipi-plugin. We can reproduce easily this tool with digiKam core (JpegUtils +
DImg). This will give a better integration in digiKam GUI. Your viewpoints ?

Gilles: There is some matrix multiplication code in JPEGlossless that combines
the current EXIF flag with the wished behavior - you see the image exif-rotated
in portrait mode and rotate by 90°, the actual rotation is either 0° or 180°
and resetting the exif flag. This code must not be lost.
Generally I would agree to putting this into BQM for ex.

Short amendment to my comment #3:
The matrix multiplication code is available from libkexiv2 now.

I seems this bug shows it's ugly face again. The thumbnail does rotate, but not
the picture nor in slideview. Using the Gimp and open it, save it, then the
picture is correct in all views. The same problem in Gwenview. Are they using
the same library?

If you use JPEG file, yes, libjpeg is common library

yes, Exiv2 is common to gwenview and digiKam, but Gwenview do not use
libkexiv2.

I will be interesting to see which file format is relevant of this problem...

hmm if I'm not wrong Tom (comment #7) experienced the opposite problem, e.g.
thumbnail ok but the picture is not really rotated.
I believe it's more like mandriva bug
