Command-line cropping

[dzenanz]

I need to crop many (192) png images into left and right parts, while avoiding some object in the middle. Images are of different resolutions. I have coordinates of these objects (it is output of my program), and I can control the format of these coordinates.

What is the simplest way to do this? I am not afraid to write scripts, I just don't know XnView's syntax.

Do you have tried nconvert?

Code: Select all

nconvert -crop x y w h -out png -o out.png input.png

Yes, this is what I was looking for. Thank you and cday (who sent emails).
