Re: Mac OS image editors?
The halves are the same size, but the problem with a program like Mac's Preview or Paintbrush is that there doesn't seem to be a way to make the canvas bigger, thus creating space to paste the second half and line it up seamlessly. That's how I used to do it in Paint, but there doesn't seem to be an option for doing so with an existing image in those programs. Unless I've missed something, which isn't entirely out of the question.
