I've got a PDF that is automatically generated from a certain piece of software, that I want to include in the report I'm writing. I'm using pdfpages which gets the job done elegantly, but the problem is, the PDF has a lot of white space around the actual content (which is a graphics) and I always have to do some tedious post-processing of the automatically generated document so that it fits well in my report. Changing the output of the software to eliminate the white space is not an option (or at least, would be much more trouble than it's worth).

I checked the pdfpages manual, but wasn't able to find an option that does that. Ideally, I'd like to be able to set margins from each direction, and the PDF is then cropped accordingly and included.

What other options do I have to control what portion of the included PDF is visible in the final document?

run pdfcrop on the whole document, then every page is cropped and you can input it as usual with pdfpages or alternatively with inlcudegraphics[page=...]{<image>}. I always use the pdfcrop from Heiko Oberdiek which is already part of every TeX distribution. And, of course, Windows user need an installed Perl, eg http://www.activestate.com/perl

You can crop/trim a pdf when including it using the trim=left botm right top.

Full example:

begin{figure}[htbp]

    centering

        includegraphics[clip, trim=0.5cm 11cm 0.5cm 11cm, width=1.00textwidth]{gfx/BI-yourfile.pdf}

    caption{Title}

    label{fig:somthing}

end{figure}

Note:
Figuring out how far to trim can take time. To speed things up a bit it helps to draw a box around the image:

   fbox{includegraphics[trim=0.5cm 11cm 0.5cm 11cm]{gfx/BI-yourfile.pdf}}

If the coordinates of the valuable parts in your PDF images is fixed,
then the following method can be automated.

Use the following template to trim or crop images and compile it with xelatex. You will get 2 pages, one for navigation and the other one is the cropped image.

% cropping.tex

documentclass{article}

usepackage{pstricks}

usepackage{graphicx}





usepackage[active,tightpage]{preview}

PreviewEnvironment{pspicture}



% Set the border to 0pt if you don't like paddings.

PreviewBorder=1cmrelax





% If you need 4 colored paddings, uncomment the following.

% But  remmember that PreviewBorder=0 will ignore it.

%pagecolor{yellow!10}



newsaveboxIBox

saveboxIBox{includegraphics[width=linewidth]{leibniz.jpg}}



defN{15}% columns

defM{15}% rows



psset

{

   xunit=dimexprwdIBox/Nrelax,

   yunit=dimexprhtIBox/Mrelax

}





begin{document}

    % First page for navigation

    begin{pspicture}(N,M)

        rput[bl](0,0){useboxIBox}

        psgrid[style=gridstyle]

    end{pspicture}



    % Second page for the final output

    % Cropping coordinates

    defLeft{6}

    defBottom{8}

    defRight{10}

    defTop{13}

    begin{pspicture}(Left,Bottom)(Right,Top)

        begin{psclip}{psframe[linestyle=none](Left,Bottom)(Right,Top)}

            rput[bl](0,0){useboxIBox}

        end{psclip}

    end{pspicture}

end{document}

From within your main TeX document, you can import the second page of cropping.pdf simply by using includegraphics[page=2,scale=<number>]{cropping.pdf}.

Please read the comments in the source file to modify the padding thickness or padding color.

Note: This example uses Gottfried Leibniz's picture.

Since you'd like to "...set margins from each direction, and the PDF is then cropped accordingly..." in order to "...control what portion of the included PDF is visible in the final document..." I would suggest you try Briss. It's easy to use and gives you much more control than pdfcrop.

You can do this with pdfpages. The following example takes a two-up scan of a book, and crops and collates it to a one-up document.

documentclass[letterpaper]{minimal}

usepackage[pdftex,letterpaper]{geometry}

usepackage{pdfpages}

usepackage{ifthen}



newcounter{pg}

begin{document}

setcounter{pg}{1}

%% my pdf file has 132 pages:

%% my pdf file has size 780 x 610 points

whiledo{value{pg}<133}{%

includepdf[pages=thepg,viewport=0 0 390 610]{scan.pdf}

includepdf[pages=thepg,viewport=390 0 780 610]{scan.pdf}

addtocounter{pg}{1}

}%

end{document}

On Mac OS-X you can use Skim or the built-in Preview to crop PDFs: Just open the PDF, select the crop area and choose Tools->Crop (⌘+K).

If you need to keep the original, just copy the selection (⌘+C) and choose File->New from Clipboard (⌘+N).

If you want to use one of the LaTeX-based methods, Skim might still be helpful to determine the bounding box coordinates (it prints them in the status bar when selecting an area).
