+incgraph provides tools for including graphics on full paper size. The graphics
+can be centered for a given paper format or the paper may be resized to the
+graphics dimensions. The main use case for the package incgraph is to transform
+one or many scans or taken pictures to a PDF document. It can also be applied
+for full paper size LaTeX created graphics. The package incgraph provides a tool
+box with basic macros and a convenience user interface which wraps the
+well-known includegraphics. Also, bookmarking is especially supported.

+  |incgraph| provides tools for including graphics on full paper size.
+  The graphics can be centered for a given paper format or the paper may be
+  resized to the graphics dimensions.
+  The main use case for the package |incgraph| is to transform one or many scans
+  or taken pictures to a PDF document. It can also be applied for full paper size
+  \LaTeX\ created graphics.
+  The package |incgraph| provides a tool box with basic macros and a
+  convenience user interface which wraps the well-known |includegraphics|.
+  Also, bookmarking is especially supported.

+\section{Introduction}
+\subsection{Motivation}
+The main purpose of this package is to include one or more graphics on full
+paper size. This means that a graphic is either centered on a blank page
+presumable of the given document paper size or the page is resized
+to the dimensions of the graphic.
+For the graphics, JPG files or PDF files or other supported formats may be
+used by inclusion. Alternatively, the graphics (or whatever) can be produced
+by \LaTeX\ code.
+An important use case for the package |incgraph| is to transform one or many scans
+or taken pictures to a PDF document. Optionally, the included graphics can
+be commented with bookmarks for the resulting PDF document.
+
+The well-known |graphicx| package \cite{carlisle:1999a} allows the inclusion
+of several types of external graphics files. The convenience user interface
+of |incgraph| described in Section \ref{sec:interface} relies on this package and adds
+assistance for the described purpose. Note that the package is designed for and
+tested with |pdflatex| to produce PDF directly. Some features like the paper
+resizing may not be applicable for other work-flows.
+
+Many of the features of the convenience user interface can be used directly
+with various basic macros. These are collected and described
+as a 'basic tool box' in Section \ref{sec:basictoolbox}.
+
+If this package does not aid your intended purpose, you may take a look
+at the |pdfpages| package \cite{matthias:2012a} which also supports the insertion of
+external multi-page PDF documents.
+
+
+\subsection{Loading the Package}
+|incgraph| is loaded in the usual manner in the preamble:
+\begin{dispListing}
+\usepackage{incgraph}
+\end{dispListing}
+
+The package |incgraph| loads the package
+|pgfkeys| \cite{tantau:2013a}. If no options are given, it also
+loads the packages |pgf|, |pgffor| \cite{tantau:2013a},
+the package |graphicx| \cite{carlisle:1999a}, and the
+package |bookmark| \cite{oberdiek:2011a}.
+
+\begin{itemize}
+\item The option |nopgf| prevents the loading of |pgf| and |pgffor|.\\
+  The opposite option |pgf| resets to loading the packages.
+\item The option |nographicx| prevents the loading of |graphicx|.\\
+  The opposite option |graphicx| resets to loading the package.
+\item The option |nobookmark| prevents the loading of |bookmark|.\\
+  The opposite option |bookmark| resets to loading the package.
+\end{itemize}
+
+So, the minimal package loading is done with the following:
+\begin{dispListing}
+\usepackage[nopgf,nographicx,nobookmark]{incgraph}
+\end{dispListing}
+
+Note that you can always load the mentioned packages yourself. This is
+intended to avoid possible option clashes the easy way.
+
+

+\section{User Interface}\label{sec:interface}
+
+\subsection{Inclusion Macros for External Graphics}
+The macros of this section rely on the |\includegraphics| command from
+the package |graphicx| \cite{carlisle:1999a}.
+%Section \ref{sec:basictoolbox} describes more basic commands.
+
+\begin{docCommand}{incgraph}{\oarg{options}\oarg{graphics options}\marg{file name}}
+  The picture file with the given \meta{file name} is included in the center
+  of a separate page. Depending on the \meta{options}, this page keeps the
+  document size or is resized to the graphics dimensions.
+  The applicable \meta{options} are listed in Section \ref{sec:keys}.
+  If \meta{graphics options} are given, these are added to the options for
+  the underlying |\includegraphics| command. See the documentation of
+  |graphicx| \cite{carlisle:1999a} for a list of applicable \meta{graphics options}.
+
+
+\begin{texexptitled}[listing only,before={\par\medskip}]%
+  {The hand-drawn example (centered); see page~\pageref{exacenter}}{exacenter.listing}
+\incgraph[paper=current,label={exacenter},overlay page number at bottom,
+  bookmark={The hand-drawn example (centered)}]{example.jpg}
+\end{texexptitled}
+
+\begin{texexptitled}[listing only,before={\par\medskip}]%
+  {The hand-drawn example (resized page); see page~\pageref{exaresized}}{exaresized.listing}
+\incgraph[paper=graphics,label={exaresized},
+  bookmark={The hand-drawn example (resized page)}]{example.jpg}
+\end{texexptitled}
+
+\begin{texexptitled}[listing only,before={\par\medskip}]%
+  {The hand-drawn example (rotated and oversized); see page~\pageref{exarotated}}{exarotated.listing}
+\incgraph[paper=current,label={exarotated},target=oversized,
+  bookmark={The hand-drawn example (rotated and oversized)}]%
+  [angle=30,scale=3]{example.jpg}
+\end{texexptitled}
+\end{docCommand}
+
+\enlargethispage*{1cm}
+\begin{docCommand}{incmultigraph}{\oarg{options}\oarg{graphics options}\marg{file name pattern}\marg{list}}
+  All picture files matching the given \meta{file name pattern} where some
+  parts are substituted by elements of the \meta{list}
+  are included in the center of a separate page. Depending on the \meta{options}, the pages keep the
+  document size or are resized to the graphics dimensions.
+  The applicable \meta{options} are listed in Section \ref{sec:keys}.
+  If \meta{graphics options} are given, these are added to the options for
+  the underlying |\includegraphics| command. See the documentation of
+  |graphicx| \cite{carlisle:1999a} for a list of applicable \meta{graphics options}.\\
+  The \meta{list} may contain any construction allowed for the |\foreach| statement \cite{tantau:2013a},
+  especially a list of numbers.
+  The elements of the list can be used inside the \meta{file name pattern}
+  with the following macros:
+  \begin{itemize}
+  \item\docAuxCommand{n}: The current element of the list (may be a number).
+  \item\docAuxCommand{ni}: The position of the current element inside the list, i.\,e.\ |\ni|
+    counts from 1 to the size of the list.
+  \item\docAuxCommand{nn}: The zero-filled |\n|, if |\n| is a number. The digit
+    number of |\nn| is determined by \refKey{/igr/zerofill}.
+  \end{itemize}
+  The resolved \meta{file name pattern} is stored inside the macro:
+  \begin{itemize}
+  \item\docAuxCommand{nt}: This file name may be used for bookmarking.
+  \end{itemize}
+  In the default behavior, non existing files are ignored.
+
+\begin{texexptitled}[listing only,before={\par\medskip}]%
+  {A series of pictures; see from page~\pageref{exaseries.1}. The image files
+    exaimage-0001.png to exaimage-0150.png are included but only three
+    of them exist.}{exaseries.listing}
+\incmultigraph[zerofill=4,bookmark={A series of pictures: \nt},
+  paper=current,label={exaseries.\n}]{exaimage-\nn.png}{1,...,150}
+\end{texexptitled}
+\end{docCommand}
+
+\subsection{Inclusion Macro for Internal Graphics}
+
+\begin{docEnvironment}{inctext}{\oarg{options}}
+  The environment content is included in the center
+  of a separate page. Depending on the \meta{options}, this page keeps the
+  document size or is resized to the content dimensions.
+  The applicable \meta{options} are listed in Section \ref{sec:keys}.
+
+

+\section{Examples}
+
+\subsection{Including some Scans to Standard Paper}
+In this scenario, we have some scans (or images from whatever source) which
+should be combined to a PDF document for our paperless office.
+The paper size of the PDF document is set to a standard paper (here: letter size)
+to allow the document to be printed.
+
+The following Example \ref{somescans} is a complete template for such a document.
+Here, the images |example.jpg|,
+|exaimage-0001.png|,
+|exaimage-0037.png|, and
+|exaimage-0123.png| are used for the resulting document.
+All included images are automatically bookmarked with the page number and
+the file name of the source image.
+
+\def\thecurrentexample{\jobname-example-a.tex}
+\tcbinputlisting{listing file=\thecurrentexample,listing only,
+  example={\texttt{\thecurrentexample}}{somescans}}
+
+The compiled result of this stand-alone source code is not found in this document but as
+a separate file in the documentation directory of the package.
+
+
+
+\clearpage
+\subsection{Creating a Picture Book}
+For this example, we assume again that a bunch of image files is to be
+combined to a PDF document. This time, the target document should be read or
+displayed mainly on computer screens and may never be printed. Therefore,
+the paper size is set flexible for the current image.
+
+The following Example \ref{picturebook} is a complete template for such a document.
+All included images are resized to a common width, but this is not necessary.
+The resulting document is considered as an e-book where the bookmarks are the
+most important navigation accessory.
+Single page inclusions with \refCom{incgraph} are bookmarked directly, but
+multi-page inclusions with \refCom{incmultigraph} can be bookmarked using the
+map-and-match feature of the package.
+The example shows a mixed usage of the macros.
+Note that the bookmarks of the multi-page part are matched with the numbers
+contained in the file names of |exaimage-0001.png| to |exaimage-0150.png|.
+
+\def\thecurrentexample{\jobname-example-b.tex}
+\tcbinputlisting{listing file=\thecurrentexample,listing only,
+  example={\texttt{\thecurrentexample}}{picturebook}}
+
+The compiled result of this stand-alone source code is not found in this document but as
+a separate file in the documentation directory of the package.
+
+
+\clearpage
+\subsection{Reformatting from Letter to DIN A4 (and vice versa)}
+In this scenario, we assume to have a PDF document with the 'wrong' paper size.
+Here, |incgraph-example-a.pdf| has the letter format, but DIN A4 paper
+is needed. |incgraph| is used to reformat to the desired paper size.
+Of course, it also works the other way around.
+
+The following Example \ref{reformatting} is a complete template for such a document.
+The document gets the desired paper size with the \refKey{/igr/paper} option.
+Then, all four pages of the original document are imported to the new paper
+size. Note that the actual document content itself is not resized because
+letter and DIN A4 are not so very different. If needed, the content could be
+shrunk or enlarged easily by adding a |scale| option for the underlying
+|\includegraphics| macro.
+
+
+\def\thecurrentexample{\jobname-example-c.tex}
+\tcbinputlisting{listing file=\thecurrentexample,listing only,
+ example={\texttt{\thecurrentexample}}{reformatting}}
+
+The compiled result of this stand-alone source code is not found in this document but as
+a separate file in the documentation directory of the package.
+
+
+
+
+\clearpage
+\subsection{Drawing on Full Paper Size}
+
+
+
+In the following examples, no external image is included to the document.
+Instead, the image (or whatever) is created inside the document and put
+on a separate page which could be resized or take the original document
+paper size.
+
+In Example \ref{fullpaperdrawing1}, a |tikzpicture| is drawn. The whole
+picture is put inside an \refEnv{inctext} environment which puts the drawing
+on a separate page which gets the dimensions of the drawing.
+
+\begin{texexptitled}[listing only]{Creation of a special text page (resized)}{fullpaperdrawing1}

+See the result on the following page.

+\section{Basic Tool Box}\label{sec:basictoolbox}
+In this section, some basic macros of the package are documented.
+It is assumed that most users will only need the macros from the
+user interface described in Section \ref{sec:interface} and Section \ref{sec:keys}.
+
+
+\subsection{Full Page Commands}
+
+\begin{docCommand}{igrpage}{\marg{text}}
+  The \meta{text} is put on a separate page which is resized to fit the
+  dimensions of the \meta{text}. \meta{text} may be single letter, an
+  included picture, or any \LaTeX\ code.
+  The page number is stored into \docAuxCommand{theigrpage} and
+  \docAuxCommand{igrAutoTarget} holds a hyper target value for bookmarking.
+  The style of the separate page is set to
+  the content of the macro
+  \docAuxCommand{igrpagestyle} which defaults to 'empty' but can be
+  redefined.
+\end{docCommand}
+
+\begin{docCommand}{igrcenter}{\marg{text}}
+  The \meta{text} is put in the center of a separate page which has the
+  current document dimensions. \meta{text} may be single letter, an
+  included picture or any \LaTeX\ code.
+  The page number is stored into \docAuxCommand{theigrpage} and
+  \docAuxCommand{igrAutoTarget} holds a hyper target value for bookmarking.
+  The style of the separate page is set to
+  the content of the macro
+  \docAuxCommand{igrpagestyle} which defaults to 'empty' but can be
+  redefined.
+\end{docCommand}
+
+\begin{docCommand}{igrcenterfit}{\marg{width}\marg{height}\marg{text}}
+  The \meta{text} is put in the center of a separate page which
+  is resized to the given \meta{width} and \meta{height}.
+  \meta{text} may be single letter, an
+  included picture or any \LaTeX\ code.
+  The page number is stored into \docAuxCommand{theigrpage} and
+  \docAuxCommand{igrAutoTarget} holds a hyper target value for bookmarking.
+  The style of the separate page is set to
+  the content of the macro
+  \docAuxCommand{igrpagestyle} which defaults to 'empty' but can be
+  redefined.
+\end{docCommand}
+
+
+\begin{docCommand}{igrtargetset}{\marg{anchor}}
+  The next value for \docAuxCommand{igrAutoTarget} is set to \meta{anchor}.
+  This can be used for hand-made hyperlinks or bookmarks.
+  An application for |igrtargetset| is found in Example~\ref{fullpaperdrawing2}
+  on page~\pageref{fullpaperdrawing2}.
+\end{docCommand}
+
+\clearpage
+\subsection{Box Commands}
+
+\begin{docCommand}{igrboxset}{\marg{text}}
+  The \meta{text} is put into a \TeX\ box named \docAuxCommand{igrbox}.
+  Additionally, some auxiliary macros are defined:
+  \begin{itemize}
+  \item\docAuxCommand{igrAutoTarget}: unique value for a hyper target.
+  \item\docAuxCommand{igrBoxWidth}: width of the |\igrbox|.
+  \item\docAuxCommand{igrBoxHeight}: total height of the |\igrbox|.
+  \item\docAuxCommand{igrBoxht}: height of the |\igrbox|.
+  \item\docAuxCommand{igrBoxdp}: depth of the |\igrbox|.
+  \end{itemize}
+\begin{dispExample}
+  \igrboxset{This is an example}
+  |\igrAutoTarget| = \igrAutoTarget, |\igrBoxWidth| = \igrBoxWidth,
+  |\igrBoxHeight| = \igrBoxHeight,\\
+  |\igrBoxht| = \igrBoxht, |\igrBoxdp| = \igrBoxdp;
+\end{dispExample}
+\end{docCommand}
+
+\begin{docCommand}{igrboxcenter}{}
+  The current content of the |\igrbox|
+  is put in the center of a separate page which has the
+  current |pdfpage| dimensions.\\ 
+  The style of the separate page is set to
+  the content of the macro
+  \docAuxCommand{igrpagestyle} which defaults to 'empty' but can be
+  redefined.
+  Note that a |\clearpage| or similar has to be inserted before this command.
+\end{docCommand}
+
+\clearpage
+\begin{docCommand}{igrboxtikz}{}
+  The current content of the |\igrbox| is embedded into a |\node| command
+  from the |tikz| package \cite{tantau:2013a} which has to be loaded separately.
+  Also, the bounding box is adjusted to the |\igrbox|.\\
+  To support positioning inside the picture, two |tikz| nodes named
+  |box| and |page| are defined which both take the dimensions of the |\igrbox|.
+\begin{dispExample}
+\igrboxset{\includegraphics{example.jpg}}%
+\begin{tikzpicture}%
+  \igrboxtikz%
+  \draw[blue,very thick] (0,0) rectangle (\igrBoxWidth,\igrBoxHeight);
+  \draw[red] (0,0) grid (\igrBoxWidth,\igrBoxHeight);
+  \draw[black] ([xshift=-1cm,yshift=-1cm]page.north east) circle (1cm);
+\end{tikzpicture}
+\end{dispExample}
+
+The boxing macros can also be used nested (see the result on the following page):
+\begin{dispListing}
+\igrpage{\igrboxset{\includegraphics{example.jpg}}%
+  \begin{tikzpicture}%
+  \igrboxtikz%
+  \draw[blue,very thick] (0,0) rectangle (\igrBoxWidth,\igrBoxHeight);
+  \draw[red] (0,0) grid (\igrBoxWidth,\igrBoxHeight);
+  \draw[black] ([xshift=1cm,yshift=-1cm]page.north west) circle (1cm);
+\end{tikzpicture}}
+\end{dispListing}
+\tcbusetemp
+\end{docCommand}
+
+
+\begin{docCommand}{igrboxtikzpage}{}
+  This is an alias for \refCom{igrboxtikz}.
+\end{docCommand}
+
+
+\begin{docCommand}{igrboxtikzcenter}{}
+  The current content of the |\igrbox| is embedded into a |\node| command
+  from the |tikz| package \cite{tantau:2013a} which has to be loaded separately.
+  This node is placed in the center of a bounding box which takes the current
+  page dimensions. Afterwards, |\igrBoxWidth| and |\igrBoxHeight| are
+  redefined to the dimensions of the total page.\\
+  To support positioning inside the picture, two |tikz| nodes named
+  |box| and |page| are defined. |box| takes the dimensions of the |\igrbox|
+  and |page| takes the dimensions of the |tikzpicture|.
+\begin{dispListing}
+\igrcenter{\igrboxset{\includegraphics{example.jpg}}%
+  \begin{tikzpicture}%
+  \igrboxtikzcenter%
+  \draw[help lines] (0,0) grid (\igrBoxWidth,\igrBoxHeight);
+  \draw[dashed] (box.south west) rectangle (box.north east);
+
+  \draw[very thick,<->] (page.north west)--(box.north west);
+  \draw[very thick,<->] (page.north east)--(box.north east);
+  \draw[very thick,<->] (page.south west)--(box.south west);
+  \draw[very thick,<->] (page.south east)--(box.south east);
+\end{tikzpicture}}
+\end{dispListing}
+See the result on the following page.
+\tcbusetemp
+\end{docCommand}
+
+
+\subsection{Map and Match Commands}
+
+
+\begin{docCommand}{igrsetmatchvalue}{\marg{key}\marg{value}}
+  The given \meta{key} is mapped to the given \meta{value}. Later, this
+  \meta{value} can be retrieved by \refCom{igrifmatch}.
+\begin{dispExample}
+\igrsetmatchvalue{my key A}{my value A}
+\def\keytester#1{\igrifmatch{#1}{Hurray: '\igrmatchvalue'}{'#1' unknown}}
+
+\keytester{foo}\\
+\keytester{my key A}
+\end{dispExample}
+\end{docCommand}
+
+
+\begin{docCommand}{igrsetmatches}{\marg{list}}
+  The \meta{list} is a comma separated list of \meta{key}=\meta{value} pairs.
+  On every pair, the \refCom{igrsetmatchvalue} macro is applied.
+\begin{dispExample}
+\igrsetmatches{my key A = my value A, bar = Shakespeare}
+\def\keytester#1{\igrifmatch{#1}{Hurray: '\igrmatchvalue'}{'#1' unknown}}
+
+\keytester{foo}\\
+\keytester{bar}\\
+\keytester{my key A}
+\end{dispExample}
+\end{docCommand}
+
+
+\begin{docCommand}{igrifmatch}{\marg{key}\marg{then}\marg{else}}
+  If a \meta{key} was defined by \refCom{igrsetmatchvalue} or
+  \refCom{igrsetmatches}, the corresponding value is put in the
+  macro \docAuxCommand{igrmatchvalue} and the \meta{then} code is
+  executed. If the \meta{key} is unknown, the \meta{else} code is
+  executed.
+\begin{dispExample}
+\igrsetmatches{1 = January, 2 = February, 3 = March, apr = April}
+\def\monthname#1{\igrifmatch{#1}{The name of month #1\ is \igrmatchvalue.}{%
+  You are kidding.}}
+
+\monthname{1} \monthname{foo} \monthname{2}\\
+\monthname{3} \monthname{apr} \monthname{35}
+\end{dispExample}
+\end{docCommand}
+
+
+\clearpage
+\subsection{Zero Filling Commands}
+
+\begin{docCommand}{igrmakezerofill}{\marg{macro}\marg{digits}}
+  With this command, a new \meta{macro} can be defined which takes a
+  non negative number as parameter.
+  This number is filled up with leading zeros until the
+  \meta{digits} count is reached.
+  If \meta{digits} is 0 or 1, nothing is added. A \meta{digits} value
+  greater than 10 is treated as 10 which is the maximum number of
+  possible digits.
+\begin{dispExample}
+\igrmakezerofill{\myfill}{0}
+\myfill{7}, \myfill{12}, \myfill{934}, \myfill{665234}.\\
+\igrmakezerofill{\myfill}{3}
+\myfill{7}, \myfill{12}, \myfill{934}, \myfill{665234}.\\
+\igrmakezerofill{\myfill}{5}
+\myfill{7}, \myfill{12}, \myfill{934}, \myfill{665234}.\\
+\igrmakezerofill{\myfill}{9}
+\myfill{7}, \myfill{12}, \myfill{934}, \myfill{665234}.\\
+\igrmakezerofill{\myfill}{30}
+\myfill{7}, \myfill{12}, \myfill{934}, \myfill{665234}.
+\end{dispExample}
+\begin{dispExample}
+\igrmakezerofill{\threedigits}{3}
+\threedigits{1}%
+\foreach \n in {2,...,100} {, \threedigits{\n}}.
+\end{dispExample}
+\end{docCommand}
