I have a pdf file which is getting generated with Inkscape from SVG and processed with ImageMagick. Now the PDF is a perfect DINA4 @300 DPI How can I add some marks around it? My marks should look like this: http://cl.ly/033g3t2h0U0f/A4_crop.png And I need to place this over the pdf with 3mm to overlap so it’s could be correctly cut.
