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 66.1. 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.
