You could try this plugin StraightCrop. Comes from the now defunct gimp-plugin-registry site. Tried in Kubuntu 16.04 Gimp 2.10.8 flatpak so should work on your 18.04 installation. The plugin attached, unzip and put in your Gimp user profile ~/.config/GIMP/2.10/plug-ins The permissions should already be set but check for executable anyway. In action, make a straight path then menu Image -> Transform -> Straighten & Crop rich: www.gimp-forum.net Attachments: * http://www.gimpusers.com/system/attachments/1062/original/03-crop.jpg * http://www.gimpusers.com/system/attachments/1063/original/StraightenCrop_0.py.zip -- rich404 (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: [email protected] List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
