Summary: Batch Queue Manager watermark reduces file size
Product: digikam
Version: 4.2.0
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Batch Queue Manager

When adding a watermark to a jpeg image using Batch Queue Manager and saving
the file results in a very much reduced file size. A 6.7MB original jpeg image
processed in this way ends up being saved as a 1.2MB image even with a jpeg
compression value of 100%.The process using BQM should result in an image of
about 6.2MB (which is what imagemagick and GIMP achieve).
Reproducible: Always
Steps to Reproduce:
1. Select a jpeg image
2.Enter BQM and select watermark
3. Select to save as a new file name
4. Run queue
Actual Results:
Original image was 6.7mb Resulting image saved is 1.2MB
Expected Results:
If the same watermark operation is done manually in edit within digikam the
resulting file size is 6.2MB.
This is 100% repeatable and effectively means the BQM is unusable for
watermarking images and maintaining quality of image.
