I want to crop a PNG picture.
I see how to do it with ImageMagick,
once I know the pixel-positions of the corners of the rectangle.
I'm wondering if there is a way of imposing a grid to read these numbers,
either with ImageMagick or some other application that runs under Fedora
Gimp?
But I’m still not sure what the questions is. With Gimp you can use the
rulers to pull in guidelines than can be used to snap the cursor, bounding
boxes, etc..
Thanks for your response.
I'd forgotten about gimp
(which I've always found a little difficult to use,
probably because it can do so much).
But I've downloaded it, and just need to learn how to guillotine.
You can also write a little script for gimp if you don't want to do it
interactively. See:

Personally, I don't like scripting gimp, but to each his own.
