Give this a go:

Code: Select all

convert img1.jpeg -crop 480x480+160+160 +repage img2.jpeg
I would have thought you could probably use -gravity center but I am not sure how.

Better to do a centered crop...

Code: Select all

convert img1.jpeg -gravity center -crop 480x480+0+0 +repage img2.jpeg
If on the other hand you are resizing the image to size a 480x480 box with edges clipped then you can use the formulas given in IM Examples
