%  This package allows to adjust general \LATeX\ material in several ways using a key=value interface.

% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \clearpage\section{Introduction} ^^A (((
% The standard \LaTeX{} package \pkg{graphicx} (the extended version of \pkg{graphics}) provides the macro
% \Macro\includegraphics[<options>]{<file name>} which can be used to include graphic files. Several options can be used
% to scale, resize, rotate, trim and/or clip the graphic.
% The macros \Macro\scalebox, \Macro\resizebox and \Macro\rotatebox are also provided to apply the corresponding
% operation on \LATeX{} material, which is subsequently placed inside a \Macro\hbox.
% However no macros are provided to trim or clip \LATeX{} material, most likely because this operations
% are not done by \TeX{} but by the output format, i.e.\ using PostScript (PS) or PDF operations.
%
% This package started by providing the missing macros \Macro\clipbox and \Macro\trimbox.
% Then a general \Macro\adjustbox macro which allows to combine many operations using a key=value syntax was added and
% further extended until it represented the main feature of this package.  Newly added keys are also provided as
% dedicated macros and corresponding environments.
% The \Macro\clipbox and \Macro\trimbox macros were then moved together with the required output driver code to a
% dedicated package \pkg{trimclip}. This allows documents and other packages to use these basic features without
% loading the full \pkg{adjustbox} package.
%
%
% ^^A )))2
% \subsection{Dependencies} ^^A (((2
% The \pkg{adjustbox} package and its \pkg{trimclip} sub-package require the author's other packages \pkg{adjcalc}
% (bundled with \pkg{adjustbox}) and \pkg{collectbox}, as well as the packages \pkg{xkeyval}, \pkg{graphicx} and \pkg{ifpdf}.
% The \pkg{varwidth} package is automatically loaded if installed, otherwise the \Key{varwidth} and \Key{stack} keys are
% disables as well as \Macro\stackbox and the \env{stackbox} environment.
% The \pkg{ifoddpage} package is automatically loaded if installed, otherwise the \Key{outer} and \Key{inner} keys are
% disables as well as \Macro\outersidebox and \Macro\innersidebox macros and corresponding environments.
% For features which use colors the \pkg{xcolor} package must also be loaded manually (the \pkg{color} package is fine, too).
% The experimental |split| and |pagebreak| features also require the \pkg{storebox} package to be loaded manually.
%
% ^^A )))2
% \subsection{Verbatim Support}\label{sec:verbatim} ^^A (((2
% The macros provided by \pkg{adjustbox} and \pkg{trimclip} read the content as a horizontal \TeX{} box and not as an
% macro argument in order to support verbatim content.
% This means that the braces around the content can also be written as \Macro\bgroup and \Macro\egroup:
% \begin{macroquote}
%   \adjustbox{key=value,\ldots}\AlsoMacro\bgroup~<content>\AlsoMacro\egroup
% \end{macroquote}
% Special care is taken to allow the \meta{content} to be a single macro (except \Macro\bgroup) without any braces:
% \begin{macroquote}
%   \adjustbox{key=value,\ldots}\AlsoMacro\somemacro
% \end{macroquote}
% This is to support the habit of some \LaTeX{} users to drop the braces for single token arguments.
% All environments support verbatim content.
% Note that the plain\TeX{} syntax for environments (\Macro\adjustbox\ldots\Macro\endadjustbox) can not be used
% because it will trigger \Macro\adjustbox as a macro. However, the braces around the content can be replaced
% by \Macro\bgroup and \Macro\egroup.

% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \clearpage\section{Package Options}\label{sec:options} ^^A (((
% This package accepts the following options:
%
% \begin{description}\def\oitem#1{\item[{\normalfont\opt{#1}}]}
%   \oitem{export} Exports the keys of \Macro\adjustbox to \Macro\includegraphics so that they can be used with this
%                  macro as well. Note that not all keys will works properly with \Macro\includegraphics as its internal
%                  code does not support all features. If problems occur the option |Export| should be used.
%                  For new documents it is recommended to use the macro \Macro\adjustimage{<keys>}{<filename>} instead.
%   \oitem{Export} Sets \Macro\includegraphics to be identical to \Macro\adjincludegraphics, which also allows the usage
%                  of all \Macro\adjustbox keys.
%   \oitem{pgf} This option is passed to \pkg{trimclip} and makes it to use the \pkg{pgf} package for all clip operations.
%               This overrides all automatically detected drivers.
%   \oitem{PGF} This option will pass the \opt{pgf} to \pkg{trimclip} and enable the \opt{pgfmath} option of
%               \pkg{adjcalc}, i.e.\ the \pkg{pgf}
%               package is used for clip operations and the \pkg{pgfmath} pacakge is used to parse length arguments.
%   \oitem{minimal} Only load a minimal set of code, i.e.\ \pkg{trimclip} and \Macro\adjustbox/\env{adjustbox}
%               but no additional keys and macros.
%  \end{description}
%
% \noindent
% The following options define the way length values are processed by the provided macros.
% They are passed to the \Macro\adjcalcset macro of the \pkg{adjcalc} package and load any required packages.
% These options can also be used as local keys on \Macro\adjustbox. See the \pkg{adjcalc} manual for more details on
% them.
%
% \begin{description}\def\oitem#1{\item[{\normalfont\opt{#1}}]}
%   \oitem{etex} Uses the $\epsilon$-\TeX\ primitive \Macro\glueexpr to parse length values.
%   \oitem{calc} Uses the \pkg{calc} package to parse length values.
%   \oitem{pgfmath} Uses the \pkg{pgfmath} package of the \pkg{pgf} bundle to parse length values.
%   \oitem{defaultunit}\MacroArgs!{\hspace*{-1ex}}!'='<unit>\relax
%      This sets the default unit used for values which accept length without units, e.g.\ \Key{trim}.
% \end{description}
%
% \noindent
% In addition, all driver options of the \pkg{trimclip} package are also accepted and passed to it.
% All unknown options are passed to the \pkg{graphicx} package, which might pass them down to the \pkg{graphics}
% package.

% ^^A )))
% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \clearpage\section{Main Macros}^^A (((
% The following macros and environments represent the main functionality of this package.
% Special care is taken so that the macros and the environments can have the same name.
% For starred environments the star can be either part of the name or an optional argument.
%
% \subsection{Adjust Box Content} ^^A (((2
% \vskip-\lastskip
% \DescribeMacro\adjustbox{<key=value, \ldots>}{<content>}
% The \Macro\adjustbox macro allows the modification of general \LATeX\ content using a key=value syntax.
% This can be seen as an extension of the \Macro\includegraphics macro from images to any \LATeX{} material.
% The macro supports the all \Macro\includegraphics keys and many more.
% However, they are provided as a mandatory not as an optional argument, because an \Macro\adjustbox without options
% would not make sense and can be replaced by a simple \Macro\mbox.
% As already stated the content is read as a box, not as a macro argument, therefore verbatim or other special
% content is supported and the braces can also be replaced by \Macro\bgroup and \Macro\egroup.
% There is no starred version of this macro.
%
% \DescribeEnv[<content>]{adjustbox}{<key=value, \ldots>}
% The environment version of \Macro\adjustbox. A difference to the macro is that it includes \Macro\noindent
% to suppress paragraph indention.
%
% \Needspace*{5\baselineskip}
% \clearpage\subsection{Adjust Images}
% \vskip-\lastskip
% \DescribeMacro\adjustimage{<key=value, \ldots>}{<image filename>}
% This macro can be used as an extension of \Macro\includegraphics.
% While \Macro\adjustbox is based on the same interface as \Macro\includegraphics it provides more keys and allows
% global keys set by \Macro\adjustboxset. Most keys can be exported to \Macro\includegraphics using the \opt{export}
% option, but there is no support for global keys\footnote{However some keys, but not all, can be set globally using
% \Macro\setkeys{Gin}{<includegraphic key=value pairs>}}.  Therefore it can make sense to use
% \Macro\adjustbox{<key/value pairs>}{\AlsoMacro\includegraphics{<filename>}}, which is the definition of
% \Macro\adjustimage.
% However, it does not use \Macro\includegraphics directly, but an internal macro, to allow the redefinition of
% \Macro\includegraphics.
% This macro does not require the \opt{export} option and therefore helps to avoid option clashes
% if \pkg{adjustbox} is loaded at several places.
%
%
% \DescribeMacro\adjincludegraphics[<key/value pairs>]{<image filename>}
% Like \Macro\adjustimage but in the same format as \Macro\includegraphics, i.e.\ with an optional argument.  This macro
% allows to use all features of \Macro\adjustbox on images, however special care must be taken if the values include
% `|[ ]|'.  In this case either the whole value or the while optional argument must be wrapped in `|{ }|':
% \Macro\adjincludegraphics['key='{[..]},...]{..} or \\\Macro\adjincludegraphics[{key=[..],...}]{..}. \\
% It is possible to redefine \Macro\includegraphics to \Macro\adjincludegraphics and this is done by
% the \opt{Export} option (not to be confused with the \opt{export} option).
%
% ^^A )))2
% \clearpage\subsection{Defining custom environments and macros} ^^A (((2
% After \pkg{adjustbox} is used to define custom environments to format specific content.
% If an environment contains other environments these are often written in the plain form \Macro\foo \ldots
% \Macro\endfoo to avoid the overhead of \Macro\begin and \Macro\end and to keep the outer environment name for
% meaningful error messages. As mentioned, the dual nature of \Macro\adjustbox which will detect if it is used
% as environment of macro does not permit this plain form, which can be a pitfall for custom environment definitions.
% Instead the macro form \Macro\adjustbox{<key=value>}\AlsoMacro\bgroup \ldots \Macro\egroup should be used.
% To simplify custom environment definitions based on \Macro\adjustbox/\env{adjustbox} the following macros are
% provided.
%
%
% \DescribeMacro\newadjustboxenv{<name>}[<num>][<default>]{<key=value,\ldots>}
% This declaration defines an environment and macro with the given name which will apply the given \pkg{adjustbox} keys
% to its content. The environment/macro can also posses arguments, including one leading optional argument, which can be
% used inside the key=value pairs. It is recommended to wrap the arguments into braces, e.g.\ use `|{#1}|' instead of
% `|#1|' etc., to avoid issues with potentially included commas and equal signs.
% The number and type of arguments are defined using two optional arguments in the same
% way as for \Macro\newcommand and \Macro\newenvironment.
%
%
% \DescribeMacro\newadjustboxenv*{<name>}[<num>][<default>]{<key=value,\ldots>}
% This declaration works similar to the unstarred version but only defines an environment.
% This environment can therefore be used like any other normal \LaTeX\ environment, including in its plain
% form {\macrodescstyle\textbackslash\meta{name}} \ldots {\macrodescstyle{\textbackslash end\meta{name}}}.
%
%
% \DescribeMacro\renewadjustboxenv{<name>}[<num>][<default>]{<key=value,\ldots>}
% \DescribeMacro\renewadjustboxenv*{<name>}[<num>][<default>]{<key=value,\ldots>}
% Like \Macro\newadjustboxenv and \Macro\newadjustboxenv* but will redefine an existing macro/environment and cause an
% error if it was not yet defined.
%
%
% \DescribeMacro\provideadjustboxenv{<name>}[<num>][<default>]{<key=value,\ldots>}
% \DescribeMacro\provideadjustboxenv*{<name>}[<num>][<default>]{<key=value,\ldots>}
% Like \Macro\newadjustboxenv and \Macro\newadjustboxenv* but will define a macro/environment only if it does not exists
% yet.
%
%
% \DescribeMacro\declareadjustboxenv{<name>}[<num>][<default>]{<key=value,\ldots>}
% \DescribeMacro\declareadjustboxenv*{<name>}[<num>][<default>]{<key=value,\ldots>}
% Like \Macro\newadjustboxenv and \Macro\newadjustboxenv* but will always define a macro/environment even if it does already exist.

% \DescribeMacro\newadjustboxcmd{<\textbackslash macro>}[<num>][<default>]{<key=value,\ldots>}
% This declaration defines a macro which applies the given \pkg{adjustbox} keys to its content.
% As with \Macro\adjustbox the content is read as box, not as macro argument.
% The macro arguments (if any) are defined in the same way as with \Macro\newcommand.
% The arguments can then be used inside the key=value pairs. The number of arguments does not
% include the content.
% This declaration is intended if no environment form is required and is more efficient than the dual declaration.

% These macros allow to define new versions of \Macro\adjustimage with predefined key lists.
% The new define image macros can also have arguments which can be used in the predefined key list to

%
% They work like \Macro\newcommand, \Macro\renewcommand and \Macro\providecommand, respectively, where
% \meta{num} is the number of arguments and \meta{default} provides a default value for the then optional
% first argument. However, instead of a macro content a \meta{key=value} list must be present, which can
% contain the arguments (|#1|, |#2|, etc). If arguments are used as values they should be wrapped in braces.
% If there are only part of a value the whole value should be wrapped in braces. This is to avoid causes commas
% inside the arguments to cause issues with the key=value list.

% argument of \Macro\adjustbox\ / \env{adjustbox}, while the starred version will place them afterwards.
%
% If these macros are used several times there keys are accumulated. This happens in the given order for the normal
% version and in reversed order for the starred version, i.e.\ the keys of further \Macro\adjustboxset or
% \Macro\adjustboxset* are always added so they face inwards.  If used without any keys but an empty argument, all keys
% previously set with the same macro are removed (from the current \TeX\ scope).  This means \Macro\adjustboxset{}
% clears all keys set be previously usages of \Macro\adjustboxset{<keys>} and \Macro\adjustboxset*{} clears all set by

% All length values given in the arguments of all macros and keys provided by this package are parsed
% by and advanced version of \Macro\setlength\relax (called \Macro\adjsetlength) which uses either $\epsilon$-\TeX\
% expressions (default), the \pkg{calc} package (default fall-back) or the \Macro\pgfmathparse of the \pkg{pgf} package.
% This allows for arithmetic expressions in these arguments. See the package options in \autoref{sec:options} to learn
% how to change the used length parser.  Note that early versions of this package used \Macro\pgfmathparse by default.
% Older documents therefore might need now use the \opt{pgfmath} option to compile correctly.
%
% Note that the four values for \Macro\trimbox and \Macro\clipbox as well as for the

% If no unit is provided for of the bounding box coordinates (left, bottom, right, top) in the trim and clip features then

% the \Key{trim} and \Key{viewport} options of \pkg{graphicx}'s \Macro\includegraphics. Note that \pkg{graphicx}
% converts all values, independent if a unit is provided or not, internally to bp, because graphics where traditionally
% stored in Encapsulated PostScript (EPS) files. The more modern PDF files also use bp instead of pt.  Because the
% \pkg{adjustbox} package macros target \LATeX{} material and users will mostly use pt values this internal conversion
% to bp got disabled for them to avoid unnecessary rounding errors. Since v0.5 the default unit can be changed using the

% \clearpage\section{Adjustbox Keys} ^^A (((
% This packages provides the following \Macro\adjustbox keys with matching macros and environments.
%
%
% \subsection{Trimming and Clipping} ^^A (((2
% The following keys allow content to be trimmed (i.e.\ the official size is made smaller, so the remaining material
% laps over the official boundaries) or clipped (overlapping material is not displayed).
% These keys come in different variants, where the lower-case keys represent the behavior of
% the corresponding \Macro\includegraphics keys. The corresponding macros (\Macro\trimbox, \Macro\clipbox, etc.)
% and environments (\env{trimbox}, \env{clipbox}, etc.) are included in the
% accompanying \pkg{trimclip} package and are explained in its manual.
%
% \DescribeKey{trim}'='<all sites>
% \DescribeKey{trim}'='<left/right>~<top/bottom>
% \DescribeKey{trim}'='<left>~<bottom>~<right>~<top>
% This key represents the original \Key{trim} key of \Macro\includegraphics but accepts its value in different forms.
% Unlike most other keys it always acts on the original content independent in which order it is used with other keys.
% If only one value is given it will be used for all four sites.
% If only two values are given, seperated by a space, the first one will be used for the left and right side and the second for the
% bottom and top side.
%
%
% \DescribeKey{viewport}'='<left>~<bottom>~<right>~<top>
% This key represents the original \Key{viewport} key of \Macro\includegraphics.
% It always trims the original content to the given view port independent from its position.
%
% \DescribeKey{clip}
% \DescribeKey{clip}'=true|false'
% This boolean key represents the original \Key{clip} key of \Macro\includegraphics.
% It is intended to be used to make \Key{trim} or \Key{viewport} clip the trimmed material.
% Note that the material will still be part of the output file but is simply not shown.
% It might be exported from the output file using special tools, so using it to censor classified information is a
% bad idea.
%
%
% \DescribeKey{Trim}'='<all sites>
% \DescribeKey{Trim}'='<left/right>~<top/bottom>
% \DescribeKey{Trim}'='<left>~<bottom>~<right>~<top>
% \DescribeKey{Viewport}'='<left>~<bottom>~<right>~<top>
% The normal \Key{trim} and \Key{viewport} keys are applied on the original content before any resizing or (most) other
% keys take effect.  This is because for \Macro\includegraphics the trimming is done by the internal graphic driver,
% while the effects can be applied later (but can also be driver dependent).
% If the \Key{trim} and \Key{viewport} keys are used multiple times only the last values will be used for the trimming,
% i.e. the content is only trimmed once. The upper case variants \Key{Trim} and \Key{Viewport} will wrap the content
% internally in a \Macro\trimbox or \Macro\trimbox*\relax macro which can be applied multiple times, e.g.\ before and
% after the content is rotated.  These two keys awaits the same format as the original keys. However, the \Key{clip} key
% has no effect on them.
%
%
% \DescribeKey{Clip}'='<all sites>
% \DescribeKey{Clip}'='<left/right>~<top/bottom>
% \DescribeKey{Clip}'='<left>~<bottom>~<right>~<top>
% \DescribeKey{Clip*}'='<left>~<bottom>~<right>~<top>
% The \Key{Clip} key will clip the given amounts from the current content and can be used several times if required.
% The starred version will use the given coordinates as \Key{viewport}.
% These keys work by wrapping the content internally in a \Macro\clipbox or \Macro\clipbox*\relax macro.
%
%
% \DescribeKey{rndcorners}'='<radius for all four corners>
% \DescribeKey{rndcorners}'='<left corners>~<right corners>
% \DescribeKey{rndcorners}'='<upper left>~<upper right>~<lower left>~<lower right>
% This key produces round corners by clipping the content. This is done using the same way as the
% above clipping keys but instead of a rectangle clipping path one with quarter circles is used.
% The radius of the every round corner can be given separately if wanted. If only one value is given
% it is used for all four corners. If only two values are given they will be used for the left and right side, respectively.
% A value of 0pt will produce a normal rectangular corner.
% No radius should be larger than half the smallest side (minimum of \Macro\width and \Macro\totalheight).
%
% Please see also the related keys \Key{rndfbox} and \Key{rndframe}, which allow to add a rounded frame around the content as well.

%
% \DescribeKey{margin}'='<all sites>
% \DescribeKey{margin}'='<left/right>~<top/bottom>
% \DescribeKey{margin}'='<left>~<bottom>~<right>~<top>
% This key can be used to add a margin (white space) around the content. It can be seen as the opposite of \Key{Trim}.
% The original baseline of the content is preserved because \meta{bottom} is added to the depth.
% It is also available under the alternative name \Key{padding}, which can be used to more visually distinguish an inner
% margin from an outer margin e.g.\ if a frame is added.
%
% \begin{example}
%   \begin{examplecode}
%   Before \adjustbox{padding=1ex 2ex 3ex 4ex,frame,margin=1ex 2ex 3ex 4ex}{Text} After
%   \end{examplecode}
% \end{example}
%
% \DescribeKey{margin*}'='<all sites>
% \DescribeKey{margin*}'='<left/right>~<top/bottom>
% \DescribeKey{margin*}'='<left>~<bottom>~<right>~<top>
% This starred version is almost identical to the normal \Key{margin} key, but also raises the content by the \MacroArgs<bottom>
% amount, so that the original depth is preserved instead of the original baseline.
% Note that while \Key{margin} is basically the opposite of \Key{Trim}, \Key{margin*} is not the opposite of \Key{Trim*}.
% Instead it also takes the same values as the unstarred key and not viewport values like \Key{Trim*}.
% An alternative name of \Key{margin*} is \Key{padding*}.
%
% \begin{example}
%   \begin{examplecode}
%   Before \adjustbox{padding*=1ex 2ex 3ex 4ex,frame,margin*=1ex 2ex 3ex 4ex}{Text} After
%   \end{examplecode}
% \end{example}
%
%
% \DescribeKey{vspace}'='<above/below>
% \DescribeKey{vspace}'='<above>~<below>
% The \Key{vspace} key adds a vertical space before and after the content.
% This is done by adding paragraph breaks and \Macro\vspace macros, which will yield better spacing between
% paragraphs then when using the \Key{margin} key.
% However \Key{vspace} forces vertical mode around the content. Adding further keys after \Key{vspace} will force
% restricted horizontal mode again and the vertical space will be ignored. For this situation the \Key{margin} key is
% better suited.
%
% \DescribeKey{vspace*}'='<above/below>
% \DescribeKey{vspace*}'='<above>~<below>
% Identical to \Key{vspace} but uses \Macro\vspace'*' instead.
% The difference is that the vertical space is not ignored at page breaks, but its full amount is always forced.

% \DescribeKey{min height}'='<height>
% \DescribeKey{max height}'='<height>
% \DescribeKey{min totalheight}'='<total height>
% \DescribeKey{max totalheight}'='<total height>
% These keys allow to set the minimum and maximum width, height or totalheight of the content.
% The current size of the content is measured and the content is resized if the constraint is not already met,
% otherwise the content is unchanged. Multiple usages of these keys are checked one after each other, and therefore
% it is possible that a later one is undoing the size changes of an earlier one.
% A good example is \Key{max width}'='\AlsoMacro\textwidth which will limit large content to the text width but will not affect smaller
% content.

% \DescribeKey{max size}'='{<width>}{<height>}
% \DescribeKey{min totalsize}'='{<width>}{<total height>}

%
% \DescribeMacro\minsizebox{<width>}{<height>}{<content>}
% \DescribeMacro\minsizebox'*'{<width>}{<totalheight>}{<content>}
% This macro is like \Macro\resizebox of the \pkg{graphics/x} package, but only resizes the content if its natural size is smaller
% than the given \meta{width} or \meta{height}.
% If only one value should be set the other one can be replaced by "!".
% If required the content is scaled up so that the width and height is equal or larger than the given values, but does not change
% the aspect ratio.
% The star variant uses the total height instead of only the height.
% This macro is used internally for the \Key{min width}, \Key{min height}, \Key{min totalheight} and \Key{min totalsize} keys.

% The following keys can be used to adjust the vertical alignment and size of the content.
%
% \DescribeKey{valign}'='<letter>
% This key allows to vertically align the content to the top, middle and bottom.  The uppercase letters |T|, |M| and |B|
% align to the content top (i.e. all depth, no height), the geometric, vertical center (equal height and depth) and to
% the bottom (all height, no depth), respectively.  This allows the alignment of content of different size, but will not
% result in good alignment with text.  The lowercase letters |t|, |m| and |b| are aligning the content again to the top,
% center and bottom but take the current text size in account.
% The |t| letter leaves a certain height given by the macro\footnote{A macro and not a length is used to allow for
% font size relative values like \texttt{1ex}.} \Macro\adjboxvtop\relax
% (by default set to the height of \Macro\strut\relax, i.e.\ |\ht\strutbox|, which is |.7\baselineskip|),
% while |b| sets a certain depth given (as negative length) by the macro \Macro\adjboxvbottom\relax
% (by default equal to the (negated) \Macro\strut depth, i.e.\ |-\dp\strutbox|, which is |.3\baselineskip|).
% The |m| letter will center towards the vertical center of the text line which is determined by the macro
% \Macro\adjboxvcenter\relax (by default \texttt{1ex}).

% \clearpage\subsection{Horizontal Alignment} ^^A (((2
% The following keys can be used to adjust the horizontal alignment and size of the content.
%
% \DescribeKey{center}
% \DescribeKey{center}'='<width>
% This key places
% the content in a horizontal box which is by default \Macro\linewidth wide (i.e.\ as wide as a normal text paragraph)
% and centers it in it. The effect is very similar to \Macro\centerline. The original content is unchanged, but simply identical
% white space is added as a left and right margin. This is useful if the content is a figure or table and can be used as a replacement
% for \Macro\centering. One important difference is that the content will then have the given width which might influence (sub-)caption
% placement.
% If the content is wider than the available width it will stick out on both sides equally without causing an overfull hbox warning.
% Note that when \Macro\adjustbox paragraph is used at the beginning of a paragraph the normal paragraph indention is added, which
% will push the while box to the right and might cause an overfull line. In such cases a \Macro\noindent must be added beforehand.
% The \env{adjustbox} environment already uses this macro.
%
% \begin{examples}
%   \begin{examplecode}
%   \adjustbox{center}{Some content}
%   \end{examplecode}
%   \begin{examplecode}
%   \adjustbox{center=5cm}{Some content}
%   \end{examplecode}
% \end{examples}
%
%
% \DescribeKey{right}
% \DescribeKey{right}'='<width>
% Like \Key{center} this key
% places the content in a box with the given width (by default \Macro\linewidth) but right aligns it.
% If the content is wider than the available width it will stick out into the left side without causing an overfull hbox warning.
%
% \begin{examples}
%   \begin{examplecode}
%   \adjustbox{right}{Some content}
%   \end{examplecode}
%   \begin{examplecode}
%   \adjustbox{right=5cm}{Some content}
%   \end{examplecode}
% \end{examples}
%
%
% \DescribeKey{left}
% \DescribeKey{left}'='<width>
% Like \Key{center} this key
% places the content in a box with the given width (by default \Macro\linewidth) but left aligns it.
% If the content is wider than the available width it will stick out into the right side without causing an overfull hbox warning.
%
% \begin{examples}
%   \begin{examplecode}
%   \adjustbox{left}{Some content}

%   \begin{examplecode}
%   \adjustbox{left=5cm}{Some content}
%   \end{examplecode}
% \end{examples}
%
%
% \DescribeKey{inner}
% \DescribeKey{inner}'='<width>
% Like \Key{center}, \Key{left} and \Key{right} this key
% places the content in a box with the given width (by default \Macro\linewidth) but aligns it towards the inner margin.
% If the content is wider than the available width it will stick into the outer margin without causing an overfull hbox warning.
% In |twoside| mode this key is equal to \Key{left} for odd pages and equal to \Key{right} for even pages.
% For |oneside| mode it is equal to \Key{left}.
% Note that the page-is-odd test might not always lead to correct results for some material close to a page boundary, because \TeX\
% might not have decided on which page it will be placed. This can be improved by loading the \pkg{changepage} package with the
% \opt{strict} option, which uses a reference to determine the correct page number (and requires the usual additional compiler run).
%
%
% \DescribeKey{outer}
% \DescribeKey{outer}'='<width>
% Identical to \Key{inner} but aligns the content towards the outer margin.
% For |oneside| mode it is equal to \Key{right}.
% If the content is wider than the available width it will stick into the outer inner without causing an overfull hbox warning.
%
%
% \DescribeKey{pagecenter}
% \DescribeKey{pagecenter}'='<width>
% This key centers the content relative to the page and independent from the text area. Afterwards the content has the same distance to the
% left and right page borders. It differs from the \Key{center} key when the left and right page margins are different which is the case in
% |twoside| documents or in environments which change the margins.
%
% Note that the content will look misalign to the text paragraphs before and afterwards and is therefore only
% pleasing for overwide images or similar content.
%
% The optional width defaults to \Macro\linewidth and determines the official width of the content. If a smaller value is selected
% following material will be placed on the same line while maybe overlapping the content.
% Larger values will cause an |Overfull \hbox| warning.
%
% \DescribeKey{pageleftalign}
% \DescribeKey{pageleftalign}'='<width>

% This key centers the content on the text area (the box with size \Macro\textwidth$\times$\Macro\textheight containing the text on a page)
% even if the box is inside an indending environment like \env{enumerate}. For this it is assumed that the adjusted box is on the start
% of a line or paragraph. If this is not the case the content will be overlapping the material on its left side.

% It is also possible to use lap amount which absolute values are larger than the original width. In this case the resulting
% official width will be zero by default and the content will padded with the required white space.

% This macro boxes the given content and splits it in multiple fragments of the given width and height.
% This is done row by row starting from the upper left corner. The last column and row can have a smaller size than requested.
% Every fragment is placed using \Macro\splitboxcmd{<fragment box>} which is empty by default but can be redefined to e.g.\ draw
% a frame around each fragment. After every row except the last the macro \Macro\splitboxnewline is inserted which defaults to |\\|,
% but can also be redefined freely. After the last row the macro \Macro\splitboxlastnewline is inserted which defaults to \Macro\splitboxnewline.
%
% The \Macro\splitbox content is stored using \Macro\storebox from the \pkg{storebox} package and therefore the whole content should only
% be stored once in the output file if the format is supported by that package (currently only PDF).

% \DescribeEnv[<content>]{splitbox}{<split width>}{<split height>}
% Environment version of \Macro\splitbox.

% \DescribeKey{split}'='{<split width>}{<split height>}
% The \Key{split} key can be used with \Macro\adjustbox and uses \Macro\splitbox internally.

% \DescribeMacro\pagebreakbox{<content>}
% The \Macro\pagebreakbox macro will split the content into multiple parts so that if fits on the current page.
% If it is larger than the rest of the current page and the full next page it is broken again until the last part fits on a page.
% This doesn't take any baselines into account and text line in the content may be split in two.
% This might be compensated manually by redefining the \Macro\pagebreakboxoffset macro (default: `|\ht\strutbox|'), which adjust the vertical offset
% of the first part.

% The following macros can be used to define own keys or redefine existing ones.
%
% \DescribeMacro\newadjustboxkey{<key>}[<default value>]{<code>}
% \DescribeMacro\newadjustboxkey*{<key>}[<default value>]{<code>}
% Defines the new \env{adjustbox} key with the given default value if no value is provided.
% The value can be accessed inside the code as |#1|
% Without a default value an error is raised if the value is missing.
% An error is raised if the key is already defined.
%
% The normal form will add the code to the internal token register just before the previous content which is
% wrapped inside braces: \MacroArgs<code>{<previous content>}. Subsequent keys will receive this as content.
% The code can therefore read the content as macro argument. If the dimension of the content need to be accessed
% it should be boxed first using \Macro\collectbox{<code>}. Then the dimension are available using the usual
% macros and the content can be typeset using \Macro\BOXCONTENT. See the \pkg{collectbox} for additional information.
%
% The starred form simply executes the given code in the internal group without changing the token register.
% In this case the content is not directly accessible and all subsequent keys are not yet processed.
% This form is useful to locally change settings for the current \Macro\adjustbox macro or \env{adjustbox} environment.
%
%
% \DescribeMacro\renewadjustboxkey{<key>}[<default value>]{<code>}
% \DescribeMacro\renewadjustboxkey*{<key>}[<default value>]{<code>}
% Like \Macro\newadjustboxkey but will redefine an existing key.
% An error is raised if the key is not already defined.
%
%
% \DescribeMacro\provideadjustboxkey{<key>}[<default value>]{<code>}
% \DescribeMacro\provideadjustboxkey*{<key>}[<default value>]{<code>}
% Like \Macro\newadjustboxkey but will define the key only if it is not already defined.
%
%
% \DescribeMacro\defadjustboxkey{<key>}[<default value>]{<code>}
% \DescribeMacro\defadjustboxkey*{<key>}[<default value>]{<code>}

% the internal form of \Macro\resizebox. In \emph{internal} mode, i.e.\ resizing is done by the graphic driver,
% the same code is added around the inner macro. This ensures the same behaviour as \Macro\includegraphics.
