Hi,

my problem is, that I have a lot of scanned images and most of them need cropping in order to save space on the page (some of them are printed later). I use digikam to manage my images and I love the batch processor, but it doesent support batch cropping. It would be very helpful to make it an easy process. Juts like in gwenview (select the area with a rectangle) but this time in digikam.

I'm not a programmer (if I were, I'd produced a patch already ;) ) but maybe its possible to borrow some code from gwenview to do it faster and with more code reuse? Maybe go further: give the user a way to check if the selected area is ok for all of the images before doing any changes?

It would be a life saver for all hard working students collecting scanned documents for their papers :)

Thanks in advance!

Reproducible: Didn't try

The question of Batch crop processing is recurrent in bugzilla.

It's possible to make easily a tool to crop an image. But the problem is how to provide a way to see the crop result. BQM is not image editor, and do not include preview (and it's not planed to do it). Don't forget that BQM apply change to multiple items, which can have different size...

So to setup crop properties, only region crop information can be hosted tin tool settings, without to have any visual feedback of the crop.

This is why, i think a crop tool in BQM is not very suitable as well... But it's my viewpoint...
