I have been using GIMP to resize photos one by one, to say 800px-width while keeping aspect ratio. I downloaded the David Batch Processor plugin and everything looks fine, except it isn't able to resize to a predetermined width or height whilst keeping the aspect ratio.
- Relative: I can resize by % and keep aspect ratio, but the photos are of different sizes and orientation, so no one % works.
- Absolute: There isn't an option to keep aspect ratio, and no one height works for all photos.
Can someone please advise if there is a way to batch-resize photos of different original sizes using GIMP's dbp or there is some other plugin that can work?
