Now color stacks can be defined and used. +% A main color stack is maintained by the driver file \xfile{pdftex.def} +% similar to dvips or dvipdfm. However the number of color stacks +% is not limited to one in \pdfTeX. Thus further color problems +% can now be solved, such as footnotes across pages or text +% that is set in parallel columns (e.g. packages \xpackage{parallel} +% or \xpackage{parcolumn}). Unlike the main color stack, +% the support by additional color stacks cannot be done in +% a transparent manner. +% +% This package \xpackage{pdfcol} provides an easier interface to +% additional color stacks without the need to use the +% low level primitives. +% +% \subsection{Requirements} +% \label{sec:req} +% +% \begin{itemize} +% \item +% \pdfTeX\ 1.40 or greater. +% \item +% \pdfTeX in PDF mode. (I don't know a DVI driver that +% support several color stacks.) +% \item +% \xfile{pdftex.def} 2007/01/02 v0.04b. +% \end{itemize} +% Package \xpackage{pdfcol} checks the requirements and +% sets switch \cs{ifpdfcolAvailable} accordingly. +% +% \subsection{Interface} +% +% \begin{declcs}{ifpdfcolAvailable} +% \end{declcs} +% If the requirements of section \ref{sec:req} are met the +% switch \cs{ifpdfcolAvailable} behaves as \cs{iftrue}. +% Otherwise the other interface macros in this section will +% be disabled with a message. Also the first use of such a +% macro will print a message. The messages are print to +% the \xext{log} file only if \pdfTeX\ is not used in PDF mode. +% +% \begin{declcs}{pdfcolErrorNoStacks} +% \end{declcs} +% The first call of \cs{pdfcolErrorNoStacks} prints an error +% message, if color stacks are not available. +% +% \begin{declcs}{pdfcolInitStack} \M{name} +% \end{declcs} +% A new color stack is initialized by \cs{pdfcolInitStack}. +% The \meta{name} is used for indentifying the stack. It usually +% consists of letters and digits. (The name must survive a \cs{csname}.) +% +% The intension of the macro is the definition of an additional +% color stack. Thus the stack is not page bounded like the +% main color stack. Black (\texttt{0 g 0 G}) is used as initial +% color value. And colors are written with modifier \texttt{direct} +% that means without setting the current transfer matrix and changing +% the current point (see documentation of \pdfTeX\ for +% |\pdfliteral direct{...}|). +% +% \begin{declcs}{pdfcolIfStackExists} \M{name} \M{then} \M{else} +% \end{declcs} +% Macro \cs{pdfcolIfStackExists} checks whether color stack \meta{name} +% exists. In case of success argument \meta{then} is executed +% and \meta{else} otherwise. +% +% \begin{declcs}{pdfcolSwitchStack} \M{name} +% \end{declcs} +% Macro \cs{pdfcolSwitchStack} switches the color stack. The color macros +% of package \xpackage{color} (or \xpackage{xcolor}) now uses the +% new color stack with name \meta{name}. +% +% \begin{declcs}{pdfcolSetCurrentColor} +% \end{declcs} +% Macro \cs{pdfcolSetCurrentColor} replaces the topmost +% entry of the stack by the current color (\cs{current@color}). +% +% \begin{declcs}{pdfcolSetCurrent} \M{name} +% \end{declcs} +% Macro \cs{pdfcolSetCurrent} sets the color that is read in +% the top-most entry of color stack \meta{name}. If \meta{name} +% is empty, the default color stack is used. +% +% \StopEventually{ +% } +% +% \section{Implementation} +% +% \begin{macrocode} +%<*package> +% \end{macrocode} +% +% \subsection{Reload

CTAN\footnote{\url{http://ctan.org/pkg/pdfcol}}: +% \begin{description} +% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcol.dtx}] The source file. +% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcol.pdf}] Documentation. +% \end{description} +% +% +% \paragraph{Bundle.} All the packages of the bundle `oberdiek' +% are also available in a TDS compliant ZIP archive. There +% the packages are already unpacked and the documentation files +% are generated. The files and directories obey the TDS standard. +% \begin{description} +% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}] +% \end{description} +% \emph{TDS} refers to the standard ``A Directory Structure +% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories +% with \xfile{texmf} in their name are usually organized this way. +% +% \subsection{Bundle installation} +% +% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the +% TDS tree (also known as \xfile{texmf} tree) of your choice. +% Example (linux): +% \begin{quote} +% |unzip oberdiek.tds.zip -d ~/texmf| +% \end{quote} +% +% \paragraph{Script installation.} +% Check the directory \xfile{TDS:scripts/oberdiek/} for +% scripts that need further installation steps. +% Package \xpackage{attachfile2} comes with the Perl script +% \xfile{pdfatfi.pl} that should be installed in such a way +% that it can be called as \texttt{pdfatfi}. +% Example (linux): +% \begin{quote} +% |chmod +x scripts/oberdiek/pdfatfi.pl|\\ +% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/| +% \end{quote} +% +% \subsection{Package installation} +% +% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting +% \docstrip\ archive. The files are extracted by running the +% \xfile{.dtx} through \plainTeX: +% \begin{quote} +% \verb|tex pdfcol.dtx| +% \end{quote} +% +% \paragraph{TDS.} Now the different files must be moved into +% the different directories in your installation TDS tree +% (also known as \xfile{texmf} tree): +% \begin{quote} +% \def\t{^^A +% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}} +% pdfcol.sty & tex/generic/oberdiek/pdfcol.sty\\ +% pdfcol.pdf & doc/latex/oberdiek/pdfcol.pdf\\ +% test/pdfcol-test1.tex & doc/latex/oberdiek/test/pdfcol-test1.tex\\ +% test/pdfcol-test2.tex & doc/latex/oberdiek/test/pdfcol-test2.tex\\ +% test/pdfcol-test3.tex & doc/latex/oberdiek/test/pdfcol-test3.tex\\ +% test/pdfcol-test4.tex & doc/latex/oberdiek/test/pdfcol-test4.tex\\ +% pdfcol.dtx & source/latex/oberdiek/pdfcol.dtx\\ +% \end{tabular}^^A +% }^^A +% \sbox0{\t}^^A +% \ifdim\wd0>\linewidth +% \begingroup +% \advance\linewidth by\leftmargin +% \advance\linewidth by\rightmargin +% \edef\x{\endgroup +% \def\noexpand\lw{\the\linewidth}^^A +% }\x +% \def\lwbox{^^A +% \leavevmode +% \hbox to \linewidth{^^A +% \kern-\leftmargin\relax +% \hss +% \usebox0 +% \hss +% \kern-\rightmargin\relax +% }^^A +% }^^A +% \ifdim\wd0>\lw +% \sbox0{\small\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\footnotesize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\scriptsize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\tiny\t}^^A +% \ifdim\wd0>\linewidth +% \lwbox +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \end{quote} +% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's +% TDS installing feature, then some files can already be in the right +% place, see the documentation of \docstrip. +% +% \subsection{Refresh file name databases} +% +% If your \TeX~distribution +% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh +% these. For example, \teTeX\ users run \verb|texhash| or +% \verb|mktexlsr|. +% +% \subsection{Some details for the interested} +% +% \paragraph{Attached source.} +% +% The PDF documentation on CTAN also includes the +% \xfile{.dtx} source file. It can be extracted by +% AcrobatReader 6 or higher. Another option is \textsf{pdftk}, +% e.g. unpack the file into the current directory: +% \begin{quote} +% \verb|pdftk pdfcol.pdf unpack_files output .| +% \end{quote} +% +% \paragraph{Unpacking with \LaTeX.} +% The \xfile{.dtx} chooses its action depending on the format: +% \begin{description} +% \item[\plainTeX:] Run \docstrip\ and extract the files. +% \item[\LaTeX:] Generate the documentation. +% \end{description} +% If you insist on using \LaTeX\ for \docstrip\ (really, +% \docstrip\ does not need \LaTeX), then inform the autodetect routine +% about your intention: +% \begin{quote} +% \verb|latex \let\install=y\input{pdfcol.dtx}| +% \end{quote} +% Do not forget to quote the argument according to the demands +% of your shell. +% +% \paragraph{Generating the documentation.} +% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate +% the documentation. The process can be configured by the +% configuration file \xfile{ltxdoc.cfg}. For instance, put this +% line into this file, if you want to have A4 as paper format: +% \begin{quote} +% \verb|\PassOptionsToClass{a4paper}{article}| +% \end{quote} +% An example follows how to generate the +% documentation with pdf\LaTeX: +% \begin{quote} +%\begin{verbatim} +%pdflatex pdfcol.dtx +%makeindex -s gind.ist pdfcol.idx +%pdflatex pdfcol.dtx +%makeindex -s gind.ist pdfcol.idx +%pdflatex pdfcol.dtx +%\end{verbatim} +% \end{quote} +% +% \section{Catalogue} +% +% The following XML file can be used as source for the +% \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}. +% The elements \texttt{caption} and \texttt{description} are imported +% from the original XML file from the Catalogue. +% The name of the XML file in the Catalogue is \xfile{pdfcol.xml}. +% \begin{macrocode} +%<*catalogue> +<?xml version='1.0' encoding='us-ascii'?> +<!DOCTYPE entry SYSTEM 'catalogue.dtd'> +<entry datestamp='$Date$' modifier='$Author$' id='pdfcol'> + <name>pdfcol</name> + <caption>Defines macros fpr maintaining color stacks under pdfTeX.</caption> + <authorref id='auth:oberdiek'/> + <copyright owner='Heiko Oberdiek' year='2007'/> + <license type='lppl1.3'/> + <version number='1.5'/> + <description> + Since version 1.40 pdfTeX supports color stacks. + The driver file <tt>pdftex.def</tt> for package + <xref refid='color'>color</xref> defines and uses a main color + stack since version v0.04b. + <p/> + This package is intended for package writers. + It defines macros for setting and maintaining new color stacks. + <p/> + The package is part of the <xref refid='oberdiek'>oberdiek</xref> + bundle. + </description> + <documentation details='Package documentation' + href='ctan:/macros/latex/contrib/oberdiek/pdfcol.pdf'/> + <ctan file='true' path='/macros/latex/contrib/oberdiek/pdfcol.dtx'/> + <miktex location='oberdiek'/> + <texlive location='oberdiek'/> + <install path='/macros/latex/contrib/oberdiek/oberdiek.tds.zip'/> +</entry> +%</catalogue> +% \end{macrocode} +% +% \begin{History} +% \begin{Version}{2007/09/09 v1.0} +% \item +% First version. +% \end{Version} +% \begin{Version}{2007/12/09 v1.1} +% \item +% \cs{pdfcolSetCurrentColor} added. +% \end{Version} +% \begin{Version}{2007/12/12 v1.2} +% \item +% Detection for package \xpackage{luacolor} added. +% \end{Version} +% \begin{Version}{2016/05/16 v1.3} +% \item +% Documentation updates. +% \end{Version} +% \begin{Version}{2016/05/17 v1.4} +% \item +% Use luatex85 package for new luatex compatibility +% \end{Version} +% \begin{Version}{2018/11/01 v1.5} +% \item +% Remove luatex85 dependency +% \end{Version} +% \end{History} +% +% \PrintIndex +% +% \Finale +\endinput |
