Rotate the image -- the easiest and fastest way is to use tool options, turn on reverse/corrective mode, and turn on a grid "number of lines", and change the number of lines until one lines up with the a vertical edge in the border; drag the lines to rotate them a little and get the grid line to match as well as possible, and then in case the image isn't actually perfectly square, repeat for the top and bottom inner border edges, then finally press Enter to do the rotation. Then crop the iamge with the crop tool to get rid of the border, if that's what you want, or to keep it, image->flatten image, then use rectangle select to select the inner pictiure, select->invert to change it to select the border, select->feather by 5px or so to make the edge soft, and drag the white swatch from the toolbox into the selection (if you don't have the default black and white, press d or click the black/white icon that's near the swatch). slave PS: clean the prints with a microfibre cloth, and the top of the scanner with that and eyeglass cleaner )spray onto the cloth of course, notthe scanner, and not the same cloth you use for prints; you can also use a special Japanese roller that was made for cleaning gramaphone records, https://amzn.to/2U9jN3R - but i worry that it may lift the surface of the print. -- Liam Quin - web slave for https://www.fromoldbooks.org/ with fabulous vintage art and fascinating texts to read.
