You can go back to the first posts. Gimp is a raster editor that works in pixels. If you use the measure tool between two defined points and it is 100 pixels in first image and 120 pixels in second image then to match, one of the images has to be scaled in the ratio 100:120 Another way is adding images as layers. When you open the first image (base layer) then **open-as-layers** a second image. The second layer takes the properties of the first image. The second layer can be scaled in place. I am not sure if this is what you want but layers can be 'matched' using plugins, it is called image registration. This example uses a plugin ofn-layer-aligner.py from http://sourceforge.net/projects/gimp-tools/files/scripts/ The top layer in screenshot 1 is rotated and scaled to match the base layer as screenshot 2. Notice how the whole layer is scaled (dotted line) and could be lost if you do not resize the canvas. If you are going to put 3 images side-by-side in a jpeg obviously a bit more work is required. But the earlier comment still applies. The additional images will take the properties (ppi etc) of the first opened image. rich: www.gimp-forum.net Attachments: * http://www.gimpusers.com/system/attachments/798/original/skewed.jpg * http://www.gimpusers.com/system/attachments/799/original/scaled-rot-moved.jpg -- 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
