Hopefully this is the right place to ask this type of question. I am editing a digital photo (in gimp), and need to increase canvas size slightly.
At one point, I was watching a tutorial where they extended the canvas and did something to scale only the edges of the image to fill that extra canvas i.e. without distorting or scaling the main area of the image at all, and the result was almost un-detectible.
I don't remember what that feature/technique was called or how they did it. Can anyone point me in the right direction?
EDIT: I found the video I was watching where this was done. I don't have the software used in the tutorial, and I am hoping there is some way to do it in something like Gimp, etc.
