Hi. Thanks. You (and Jernej) wrote it very clear!
Can any recommend such an editor for lossless cropping & rotating,
better even lossless resizing, if possible. Cropping, rotating and
resizing are the only feature my user (not me) uses and my user wanted
to have a GUI tool. If there isn't one but only commandline tools, then
I'd see if I can re-use my tcl/tk skill to make an opensource tool for this.
