This question is similar to that one, but I'd like to execute pdfcrop when including a PDF.

When the shell escape feature (--shell-escape or --enable-write18 (MiKTeX)) is enabled, the conversion can be called via \immediate\write18{...}:

\immediate\write18{pdfcrop image.pdf}%
\includegraphics{image-crop}

The conversion can be limited to the cases, where the cropped image file not yet exists:

\IfFileExists{image-crop.pdf}{}{\immediate\write18{pdfcrop image.pdf}}%
\includegraphics{image-crop}

  • You might mention the shellesc package, which will be particularly handy when LuaTeX 0.90 will be included in TeX Live 2016 and won't support \write18.

Based on Heiko Oberdiek's answer I wrote a command to crop all included PDFs

\usepackage{xstring}
\let\oldincludegraphics\includegraphics
\renewcommand{\includegraphics}[2][width=\textwidth]{%
    \immediate\write18{pdfcrop #2}%
    \StrSubstitute{#2}{.pdf}{-crop.pdf}[\temp]%
    \oldincludegraphics[#1]{\temp}%
    }

Issues:

  • it doesn't check if the graphic is a PDF
  • it should be optional

    this is missing % at ends of lines so will add three inter-word spaces before the image, and one after. Apr 4, 2016 at 9:37
