Bug 511797

SUMMARY

The Export to local storage tool offers some options that do not seem to work.

My library is set up such that raw files and jpg files get xmp sidecar files. 
Those raw files and jpg files are read-only.
Whenever I edit tags/captions, those are stored in the xmp file of the raw file and in the xmp file of the jpg.
The motivation for this workflow is that my jpg files remain untouched and do not need to be backed up again after editing tags/captions.

Sometimes I do wish to share jpg files with friends and I may then want to include data from the .jpg.xmp file in the exported jpg file.
This is where I intend to use the "Export to local storage" tool.

STEPS TO REPRODUCE
1. Select a jpg file that has an accompanying xmp file where tags/captions are stored
2. Open Tools / Export to local storage
2.a Choose "Copy files", tick "Write sidecar metadata to the items", export
2.b Same as 2.a, but "Adjust image properties" ticked as well.
2.c Enter Image length 7000

OBSERVED RESULT
2.a The exported jpg file is simply a copy of the original one. Additional data from the sidecar file is not written into the exported jpg file.
2.b The exported jpg file has additional metadata embedded.
2.c Image length value stuck at 700

EXPECTED RESULT
2.a The exported jpg file has additional metadata embedded.
2.b The exported jpg file has additional metadata embedded.
2.c Image length value is 7000

Additionally, it would be nice to be able to enable jpg compression at a desired image quality level without resizing the images.
The jpg files in my library were usually exported at 100% jpg quality setting, but when exporting them from digikam for sharing them with friends I would want, say, 95%.
Maybe allow the imale length to be left blank and default to the dimensions of the original image?
