T.E. Andersen asks: : Hi all, : : I have a large number of scanned images with black borders. The images : are also not perfectly aligned in the frame. Could anyone suggest a way : to automatically rotate and crop the images to leave only (but all of) : the image area? Assuming a windows OS (apologies if this is wrong) firstly I'd rotate them all, and for this I'd use irfanview (surprise! ;) a bit of organization first - I'd create 2 folders called 'rr' and 'rl' (rotate right and rotate left respectively) as subfolders to where your images are. open Ifanview, press T (thumbnails) then navigate to the folder where the images are stored. hold down the control button and click each image that is to be rotated left then right click, select 'move images' , navigate to rl (maybe select button 1 for this) then press 1 on the keyboard repeat for those to be rotated right etc.. close thumbnail view navigate to the appropriate folder, open an image in irfanview then press B (batch) head to the advanced options and select rotate & hit OK repeat for the other folder then just cut and paste all the rotated images back where they came from (you can actually write a BAT file - I have - to automate almost all of that!) ok, so that's blown off three minutes or so.. now to the borders.. I found that a search led to a lot of pages using The GImp (cross platform) - google autocrop for more such as: http://docs.gimp.org/en/gimp-image-autocrop.html regards Karl (THIS was what I was fiddling with when I hit reply to the wrong email!)
