Description Martin Stjernholm 2006-03-02 09:12:08 UTC 
When I rotate an image, the resulting EXIF tag is not completely updated with the new orientation. EXIF dump before rotation:

> exiftran -d foo.jpg
foo.jpg
   ifd 0
      0x010f  Manufacturer                   FUJIFILM

Notice the two places where the orientation is stored. gthumb only updates the first, so this is what I get after rotation:

> exiftran -d foo.jpg
foo.jpg
   ifd 0

This bug causes problems with e.g. gimp that apparently favors the orientation setting in ifd 1, whereas most other programs I've tried uses the one in ifd 0.

fixed in current CVS, thanks.
