Description pveax 2020-10-21 13:58:51 UTC
Hi!
Thank you for the product!

SUMMARY
Regression: lost ability to choose jpeg quality while saving.

STEPS TO REPRODUCE
1. open a jpeg file (my example of a file attached)
2. click Menu `File` -> `Save As...`
3. choose `jpeg` format and any quality (tested 100%, 99, 98, 95, 90, 85, 70, 60)

OBSERVED RESULT
The file size is the same as origin file, so looks like no re-save/re-compression was made.

EXPECTED RESULT
The file size should be different from the origin file, cause re-save/re-compression should be made.


SOFTWARE/OS VERSIONS
Operating System: Manjaro Linux
KDE Plasma Version: 5.20.1
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
Kernel Version: 5.8.16-2-MANJARO
OS Type: 64-bit

ADDITIONAL INFORMATION
No matter of jpeg quality choice the file size is the same as origin.

Not absolutely sure then it start to happens.

Thank you!

Initial file taken from camera app and saved with `70` jpeg quality via `kolourpaint` app: re-encoding works.

Second file is saved with q60 via `gwenview` and has the same size, which means that output could be simple copy of input, no matter of encoding settings in `Save As` dialog window.
