PDF file can also optionally contain a \textit{crop box} for each page,

A crop box can be set, changed and removed, without affecting the underlying

A hard box (one which clips its contents by inserting a clipping rectangle) may be created with the \texttt{-hard-box} operation:
\begin{framed}
\small\verb!cpdf -hard-box /TrimBox in.pdf -o out.pdf!
\end{framed}
This means the resultant file may be used as a stamp without contents outside the given box reappearing.
\section{Showing Boxes and Printer's Marks}
The \texttt{-show-boxes} operation displays the boxes present on each page as method of debugging. Since boxes may be coincident, they are shown in differing colours and dash patterns so they may be identified even where they overlap. The colours are:
\medskip
\begin{tabular}{ll}
Media box & Red \\
Crop box & Green \\
Art box & Blue \\
Trim box & Orange \\
Bleed box & Pink
\end{tabular}
\medskip
The \texttt{-trim-marks} operation adds trim marks to a PDF file. The bleed and trim boxes must both be present.
