Version: (using KDE Devel) Installed from: Compiled sources OS: Linux Recent discussion on digikam-devel showed that JPEG export isn't so simple as it seems. I think specialised plugin for export to JPEG could be good thing. Such plugin should allow: - very detailed control of export settings (sampling, quality, etc.) - preview of effects for interesting details of image - to view size of image after export In future even more advanced feature would be interesting: fake zones of compression. Scenario: 1. User selects interesting area and calls plugin 2. Digikam creates two images and user can choose compression and other settings for each image separately. 3. At the end image with selected area is superimposed on image with unselected area. In this way user can minimize final size of image without losing important details.
Another interesting feature would be the ability to detect and reuse the original JPG quality settings, like Gimp.
Andre, yes, this would be good, as "Trying to improve the appearance of a Jpeg image by re-compressing at a higher quality setting achieves very little (except an increase in file-size)." http://photo.net/learn/jpeg/ This was discussed in the (closed) bug http://bugs.kde.org/show_bug.cgi?id=149578#c15 but never got implemented.
