% AUTO-PST-PDF
% This is the auto-pst-pdf package, by Will Robertson.
% Proper documentation forthcoming (if ever).
%
% This document may be distributed under the terms and conditions of
% the LaTeX Project Public License, version 1.3c or later (your preference):
% <http://www.latex-project.org/lppl.txt>
%
% The package is "maintained" by Will Robertson.
% Contact: <wspr81 [at] gmail [dot] com>
% Copyright 2006 by Will Robertson
%
% BASIC USAGE
% This package provides a wrapper around pst-pdf to automatically
% accomodate for typesetting either with DVI or PDF output. With
% default package option [on], typesetting under pdfLaTeX will
% automatically initiate a LaTeX->dvips->ps2pdf->pdfcrop run to
% generate the required PDF figures for the document.
%
% After this has been done and the figures no longer need to be
% re-generated, the package can be given the [off] option to save
% compilation time.
%
% REQUIREMENTS
% pdfTeX must be called with the --shell-escape option, and Heiko
% Oberdiek's pdfcrop Perl script must be installed.
%
% Loads the following packages for convenience:
% color,graphicx,psfrag,pst-pdf
%
% Requires e-TeX because I'm lazy.
%
% ADDITIONAL USAGE
% Macros are provided to easily facilitate figures created by the
% MATLAB package laprint and the Mathematica package MathPSfrag. Also,
% a generic psfrag wrapper is provided.
%
% \mathfig{<filename>} - insert a Mathematica graphic
% (without -psfrag suffix)
% \matlabfig{<filename>} - insert a Matlab graphic
% \psfragfig{<filename>} - insert an EPS with psfrag statements
% in either or both of the files
% <document>-psfrag.tex
% <filename>-psfrag.tex
%
% The above commands also accept an optional argument
% which is passed to \includegraphics.
%% Declaration
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{auto-pst-pdf}
[2006/11/30 v0.1 Wrapper for pst-pdf]
%% Package options
\newif\if@apstpdf@off@
\@apstpdf@off@false
\DeclareOption{off}{\@apstpdf@off@true}
\DeclareOption{on}{\@apstpdf@off@false}
\ExecuteOptions{on}
\ProcessOptions
\RequirePackage{ifpdf,etex,color,graphicx,psfrag}
%%%%%%%%%%%%%%%%%%%%%%
%% Base functionality:
%
% For compilation, we use the [notightpage] pst-pdf option and the
% pdfcrop Perl script because Matlab-created EPS figures have elements
% that extend ouside their bounding boxes, and end up with clipped
% content after ps2pdf.
%
% Otherwise the script ps4pdf would be sufficient.
\ifpdf
% pdfLaTeX compilation; requires supplementary processing for psfrag to work:
\unless\if@apstpdf@off@
\immediate\write18{latex -disable-write18 "\unexpanded{\let\APPmakepictures\empty\input}{\jobname.tex}"}
\immediate\write18{dvips -o \jobname-pics.ps \jobname.dvi}
\immediate\write18{ps2pdf \jobname-pics.ps \jobname-pics-nocrop.pdf}
\immediate\write18{pdfcrop \jobname-pics-nocrop.pdf \jobname-pics.pdf}
\fi
\RequirePackage[notightpage]{pst-pdf}
\else
\ifdefined\APPmakepictures
% LaTeX compilation induced by this package:
\RequirePackage[notightpage]{pst-pdf}
\else
% LaTeX compilation from scratch (as in `latex \jobname.tex`):
\newenvironment{postscript}{}{}
\fi
\fi
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Extras for external packages:
%
% Commands are provided that mirror \includegraphics (and similarly
% accept an optional argument) for the output of different
% psfrag-related packages. This provides a consistent and easy way to
% include such figures in the document.
%
% Please suggest wrappers for other packages that output psfrag
% (for example: R, Maple, LabView, ... ?)
%% Matlab's laprint:
% We need to disable the scaling that laprint applies
% to \includegraphics in here, because otherwise labels that extend
% outside the bounding box of the generated PostScript file will
% change the intended width of the graphic.
\let\apstpdf@ig\includegraphics
\newcommand\matlabfig[2][]{%
\begin{postscript}
\renewcommand\includegraphics[2][]{\apstpdf@ig[#1]{##2}}
\input{#2}
\end{postscript}}
%% Mathematica's MathPSfrag output:
\newcommand\mathfig[2][]{%
\begin{postscript}
\input{#2-psfrag}%
\includegraphics[#1]{#2-psfrag}%
\end{postscript}}
%% Regular old EPS graphics:
% Include your psfrag commands in the files <document>-psfrag.tex
% and/or <figname>-psfrag.tex, where <document> is the filename of the
% main document and <figname> is the filename of the graphics
% inserted.
\newcommand\psfragfig[2][]{%
\begin{postscript}
\InputIfFileExists{#1-psfrag}{}{}%
\includegraphics[#1]{#2}%
\end{postscript}}
\InputIfFileExists{\jobname-psfrag}{}{}%
