LEAP 15.1 Batch CROP and resize jpg images

Hi there,

I have a bunch of photos in various aspect ratios (4:3, 16:9, etc.) that I'd like to crop to 4:3 and resize to 800 x 600, to use in an oldish digital picture frame.

IINM I used to do this in gwenview with kipi-plugins installed, but for some time now this doesn't work, according to some old posts here it is a library version issue.

I also tried digikam but the bottom of wider photos (16:9) were padded with the bottom part of the previous 4:3 photos processed. A very weird behavior, or I did something very wrong.

I can batch rezise with something like
But I can't seem to find a way to batch crop the photos first.

Any suggestions?

Thanks,
