I haven't found any solutions for this yet. My problem is this:
When I open an image with Gimp, the editor sets a fixed size for the image. For example, I open a 1920x1080 image with Gimp. Then the Borders are also set to that size. If I now import a 500x500 image, which is smaller,there is no problem.
But if I open the 500x500 image first, and then add a 1920x1080-image, that image gets cut off:
Is there a way, to tell Gimp that it needs to rescale the image to the largest layer that exists?
