All to do with anti-aliasing. Assuming you are using Windows and Gimp 2.10 You have an alpha channel on your xcf but only one layer. Since B & W line art assuming a colour select on the white and a delete might give something like screenshot 1 You can mess around with the threshold value but the usual way is grow the selection by 1 (or 2) pixel(s) to include the semi-transparent pixels before deleting. Select menu -> Grow. screenshot 2 With Gimp 2.10 the color 2 alpha tool Color menu -> Color to Alpha is adjustable and should give a good result. screenshot 3 A more comprehensive description here: https://www.gimp-forum.net/Thread-Background-removal-or-replacement-on-text-logos-and-other-computer-graphics Attachments: * https://www.gimpusers.com/system/attachments/1210/original/01-remove.jpg * https://www.gimpusers.com/system/attachments/1211/original/02-remove.jpg * https://www.gimpusers.com/system/attachments/1212/original/03-remove.jpg -- rich404 (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
