I don't know imagemagic but there is the commandline imagestack tool which can crop images

imagestack -load inputfilename.jpg -crop startx starty width height -save outputfilename.jpg

If you can get the coordinates out of the other app you can write a script to pass them on the commandline to imagestack - details depends on your OS
