When I edit a photo, I can adjust levels, color, saturation, etc. That would be great if we could do the same as a batch process. I have a camera that gives me photo where I have to adjust levels almost always the same way.

BatchColorImage kipi-plugin use ImageMagick for all image manipulations.

In Digikam Image Editor, the Auto-levels algo in implementated like an internal library and cannot be used in this kipi-plugin dirrectly.

I want lets BatchProcessImages kipi plugins running with IM and without embedded filter implementations.

ImageMagick do not provide Auto-Levels option. Look this url :


So you can try to use Normalise option available in BatchColorImage plugin.
Certainly in the future, IM will add an auto-levels technic (perhaps it's already available in 6.1.0 release !). In this case i will added a new option with this feature in the plugin.

Yes, IM 6.1.1 provide auto-levels :


Questions opened :

-Witch IM release you use ? 
-This option is available on your system ? If true, It's work fine (like in Image Editor) ?
-Since witch IM release this option is available ?

i'm still using version 5.5.7. I think I should be able to install latest version but I'll try 'normalize' before for some tests :)

what about the color balance, saturation, etc. can they be 'batched' ? In fact, that would be great to modify levels when editing an image then apply the same modifications to other images I have choosen. mays be it should not be done in batch process ? but as an option when editing an image ?

digiKam 0.11 will have Batch Queue Manager tool. Batch AutoLevels is already implemented.

Look here for more info :


I close this file now.
