This would be an extremely useful feature and reasonably easy to add in order to save a lot of time and hassle with having to alternate with having to check and manually setting the width or height of each individual image depending on whether it’s in landscape or portrait orientation. Lightroom has this precise “longest edge” option selection when exporting images which makes changing the dimensions of images on export a one click solution.
BTW I think Gigapixel has made huge bounds in the improvement of the interface and upscaling quality. Keep up the great work.
