Lossless jpg rotation forgets to update width and length

Post by Markorki »

Hello

I use to "lossless rotate" my pictures as soon as I move them from card to my computer.
I used to do it with Windows version of XnView, but I recently used MP (0.39 beta, sept 5 2011) .

When a "vertical" picture is rotated so as to be correctly displayed even by stupid or old software, the orientation tag is modified, but "width" is not exchanged with "length" in EXIF metadata.
Such a bug has small or great consequences: duplicates pictures are not detected because they differ just by having 2 exif values "crossed" (yes, I used MP for a small batch of pictures already rotated on an other disk using 1.97, and the resulting files were different ) , and maybe some panorama generators could have a strange behaviour...
