[PLUG] Cropping .pdf using imagemagick's crop

I need to cut out a specific area in a PDF image document. I know the crop command and want to learn if there's a way to identify the corners of the cropped image other than by trial-and-error using the original image. Is there a tool that will provide x-y coordinates at the cursor location on a
