This will then open the Scale Image dialog: To resize the image to new dimensions, we need only invoke the Scale Image dialog: Notice that the information at the top of the window shows the current pixel dimensions of the image (in this case, the pixel size is 1225×1280). View of the GIMP canvas, with information at the top of the window. The thing to notice for this example is that by default the window decoration at the top of GIMP will show you some information about the image.
