% \begin{abstract}
% The PDF format has some graphics parameter like
% line width or text rendering mode. This package
% provides an interface for setting these parameters.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% This package \xpackage{pdfrender} defines an interface for
% PDF specific parameters that affects the rendering of
% graphics or text. The interface and its implementation
% uses the same technique as package \xpackage{color}
% for color settings. Therefore this package is loaded to
% enable \LaTeX's color interface.
%
% At different places \LaTeX\ uses \cs{normalcolor} to avoid that
% header, footer or floats are print in the current color of the
% main text. \cs{setgroup@color} is used to start a save box
% with the color that is set at box saving time.
% Package \xpackage{pdfrender} extends these macros to
% add its own hooks of its parameters. Therefore \LaTeX3 should
% generalize \LaTeXe's color interface.
%
% \subsection{Usage}
%
% In \LaTeX\ the package is loaded as normal package. Options
% are not defined for this package.
% \begin{quote}
% |\usepackage{pdfrender}|
% \end{quote}
%
% This package can also be used in \plainTeX\ and even ini\TeX:
% \begin{quote}
% |input pdfrender.sty|
% \end{quote}
%
% \subsection{Macros}
%
% \begin{declcs}{pdfrender} \M{key value list}
% \end{declcs}
% The first parameter \meta{key value list} contains a
% list of parameter settings. The key entry is the parameter name.
% The macro works like
% \cs{color} (without optional argument) for color setting.
%
% \begin{declcs}{textpdfrender} \M{key value list} \M{text}
% \end{declcs}
% In the same way as \cs{pdfrender} the first argument
% specifies the parameters that should be set. This parameter
% setting affects \meta{text} only. Basically it works
% the same way as \cs{textcolor} (without optional argument).
%
% \subsection{Parameters}
%
% The following table shows an overview for the supported
% parameters and values:
%
% \begin{longtable}{@{}l|l|l@{}}
% \bfseries Parameter & \bfseries Value & \bfseries Alias\\*

%
% \subsubsection{Details}
%
% The description and specification of these parameters
% are available in the PDF specification \cite{pdf-spec}.
% Therefore they are not repeated here.
%
% \begin{description}
% \item[Value:]
%   The values in the second column lists or describe
%   the values that are specified by the PDF specification.
% \item[Alias:] Instead of magic numbers the package also
%   defines some aliases that can be given as value.
%   Example: |LineCapStyle=Round| has the same effect as
%   |LineCapStyle=1|.
% \item[Number:] The term \emph{number} means an integer
%   or real number. The real number is given as plain
%   decimal number without exponent. The decimal separator is a period.
%   At least one digit must be present.
% \item[\xoption{LineWidth}:] As alias a \TeX\ dimen specification
%   can be given. This includes explicit specifications with number
%   and unit, e.g. |LineWidth=0.5pt|. Also \LaTeX\ length registers
%   may be used. If \eTeX's \cs{dimexpr} is available, then it is
%   automatically added. However package \xpackage{calc} is not
%   supported.
% \item[\xoption{FillColor}, \xoption{StrokeColor}:]
%   Package \xpackage{color} or \xpackage{xcolor} must be loaded
%   before these options can be used (since version 1.2).
%   \LaTeX's color support sets both colors at the same time
%   to the same value. However parameter \xoption{TextRenderingMode}
%   offers the value \texttt{FillStroke} that makes only sense, if
%   the two color types can be set separately.
%   If one of the options \xoption{FillColor} or \xoption{StrokeColor}
%   is specified, then also the color is set. For compatibility
%   with the \LaTeX\ color packages (\xpackage{color} or \xpackage{xcolor}),
%   always both colors must be set. Thus if one of them is not specified,
%   it is taken from the current color.
%
%   Both options \xoption{FillColor} and \xoption{StrokeColor}
%   expect a \LaTeX\ color specification as value.
%   Also the optional color model argument is supported.
%   Example:
%   \begin{quote}
%     |FillColor=yellow|,\\
%     |StrokeColor=[cmyk]{1,.5,0,0}|\\
%   \end{quote}
% \end{description}
%
% \subsection{Color stack}
%
% If the \pdfTeX\ version provides color stacks, then each
% parameter is assigned a page based color stack. The assignment
% of a stack takes place, when its parameter is set the first time.
% This avoids the use of color stacks that are not needed.

% \subsection{Hook into \cs{normalcolor}}
%
%    The problem is that packages \xpackage{color} and \xpackage{xcolor}
%    each overwrite \cs{normalcolor}. For example, after the package
%    loading order \xpackage{color}, \xpackage{pdfrender} and \xpackage{xcolor}
%    the patched version of \cs{normalcolor} is overwritten by
%    package \xpackage{xcolor}. Also using \cs{AtBeginDocument} for
%    patching is not enough. If package \xpackage{hyperref} is loaded
%    later, it might load package \xpackage{color} using \cs{AtBeginDocument}.

%% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{pdfrender}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/pdfrender.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/pdfrender.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[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTANpkg{tds}). 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}
%
% \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 pdfrender.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):

% 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
% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \TeX\,Live\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \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{pdfrender.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 pdfrender.dtx
%makeindex -s gind.ist pdfrender.idx
%pdflatex pdfrender.dtx
%makeindex -s gind.ist pdfrender.idx
%pdflatex pdfrender.dtx
%\end{verbatim}
% \end{quote}
