Cropping a PDF
20180528 There are times and circumstances where it is useful to crop a pdf document. For example, when producing the pdf for my book titled The Essentials of Data Science I placed crop marks in each of the four corners. From this original version I wanted to extract just the printable page. Through experimentation I found that introducing a margin of did the trick.
$ pdfcrop --margins -50 input.pdf output.pdf $ evince output.pdf
The original and result can be seen in Figure 67.1. The original is at the top of the figure and the cropped version, using pdfcrop with -margins 50, is at the bottom. When printing, the image will generally be expanded to fit the page, though that is often a setting within the application controlling the printing.
