How can I edit a large image file on Linux?
I have a high-res scan of an image, and I'd like to select parts of it and save them individually to be able to manipulate them.
I used GIMP to place markers on the image, and then tried using Web → Slice to autoslice the image, but it comes up with an error after a while and it only saves the first image.
edit: The image is 10208x14032 pixels, 140Mb in size. The testing computer has 3Gb of RAM
