Any code lines after the |\end{document}| will be ignored. The real \env{document} environment of the main file will be unaffected and will work as normal. +% +% The packages required by each sub-file can be transfered automatically to the main document preamble using the options +% listed in \autoref{sec:pkgoptions}. +% +% \subsection{Dependencies} +% The \cls{standalone} class and package require the \pkg{xkeyval} package. +% The packages \pkg{ifpdf}, \pkg{ifluatex} and \pkg{ifxetex} are loaded if available, otherwise some fall-back code is used. +% If enabled the class options \opt{varwidth}, \opt{preview} and \opt{beamer} require the package or class of the same name. +% +% The \pkg{standalone} package requires the \pkg{currfile} package (which in turn uses \pkg{filehook}) to track the correct file names of +% sub-files included using |\input|. +% For the compilation support for included standalone files the \pkg{gincltex} and \pkg{filemod} packages are also required. +% +% To compile the documentation of \cls{standalone} the \cls{ydoc} bundle is required. +% +% All of these packages are included in recent versions of the TeXLive or MikTeX distributions and are freely available on \href{http://www.ctan.org/}{CTAN}. +% +% \subsection{Bug reports, feature requests and other feedback} +% Bug reports, feature requests and other feedback about the \cls{standalone} bundle can be sent to the author +% either by email to \href{mailto:martin@scharrer-online.de?subject=standalone:%20}{martin@scharrer-online.de} +% or using the issue tracker for the bundle under \href{https://bitbucket.org/martin_scharrer/standalone/issues}. +% Bug reports should include the used version of \cls{standalone} as well as the used \LaTeX\ format (|pdflatex|, |latex|, |xelatex|, etc.) and distribution including its version. +% Usually a minimal example which recreate the issue is immensely helpful in analysing and solving any bug. +% Please look for existing related issue tickets first and check the FAQ/troubleshooting in \autoref{sec:classfaq} first. +% Issues related to the \opt{preview} class option should be compared with a direct use of the underlying \pkg{preview} package. +% +% \subsection{Version update and backwards compatibility} +% The default behaviour of v1.x of the \cls{standalone} class is slightly different as the one of v0.x, but should result in the same output for the majority of standalone files. +% In previous versions the \opt{preview} option was enabled by default, but since v1.0 the new, similar \opt{crop} option is now used. +% This change should improve several use-cases, like avoiding the creation of a paragraph due to a trailing empty line and issues with TikZ patterns under XeLaTeX. +% However, paragraph breaks are now ignored by default, which should be no issue at all for picture and similar environments which are the main target of the \cls{standalone} class. +% Additionally, the default border has been changed from the \pkg{preview} default of 0.50001bp to no border (0pt). +% Both of these settings can be changed back to the old default by adding \Macro\standaloneconfig{preview,border=0.50001bp} in the configuration file +% or explicitly stating these options as class options. +% +% One true incompatibility between v0.x and v1.x is the load point of the class configuration file. +% In v0.x the configuration file was loaded after all options where processed in order to have all if-switches their final value. +% In v1.x the configuration file is now loaded directly before the given class options are processed. This allows to easily set default options for all standalone files. +% Code which relies on if-switches (like \Macro{ifstandalone} and \Macro{ifstandalonebeamer}) should be placed inside a \Macro\AtEndOfClass{<code>} macro. +% This change might require an update of personal configuration files. +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Similar packages and classes} +% The following packages, libraries and/or classes target the same or similar applications as the \bundle{standalone} bundle and are mentioned here for easy comparison, so that the user can decide +% which suits them best. +% +% The \pkg{docmute} package is written for the same basic task as the \cls{standalone} package. However, no sub-preamble processing other than the removal is support. It also +% doesn't provide a special class or configuration file. +% +% The \pkg{subfile} package and class are written for the same application to allow subfiles to be compiled standalone. However, the \cls{class} class will import the preamble from a given main file, +% while \pkg{standalone} is designed more for the opposite direction where the preamble of subfiles can be imported to the main document. Therefore a \cls{standalone} file can be more easily included +% into several documents, like a paper (scientific publication), a corresponding presentation and then a thesis, while \cls{subfile} is designed for a one-to-one relationship. +% At the time of the writing \pkg{subfile} is not part of TeXLive due to a missing license statement. +% +% The \lib{external} library of \pkg{tikz} allows to externalize \env{tikzpictures} from an main document. Its build feature is similar to the one provided by \cls{standalone}. +% However, both work form different directions: \cls{standalone} allows to include external \env{tikzpictures} to be included in a main file while ignoring the preamble while +% \lib{external} writes them from the main file to temporary external files. The user must decide which workflow is better suited for him/her. +% Also \cls{standalone} is working independently of \pkg{tikz} and supports other picture environments like \pkg{pstricks} or any other \TeX\ material. +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \clearpage +% \section{Usage of the \cls{standalone} class} +% \subsection{Basic usage} +% Creating a basic standalone is straight-forward: Create a normal \LaTeX\ document which uses the \cls{standalone} as document class. +% The preamble should load all required packages and libraries for the content. The content, usually a single picture environment like \env{tikzpicture}, +% is placed in the \env{document} body. Empty lines before and after the picture should be avoided. +% Also the |\begin{document}| and |\end{document}| should each stand on a source line of their own. +% +% \par\noindent +% \begin{minipage}{\textwidth}\small +% \begin{lstlisting}[language={[latex]tex},gobble=4,frame=lines,caption={Basic use of the \cls{standalone} class.},numbers=none] +% \documentclass{standalone} +% \usepackage{somepackage} +% \begin{document} +% \begin{somepicture} +% \somedrawingcommands +% \end{somepicture} +% \end{document} +% \end{lstlisting} +% \end{minipage} +% +% Such a file can be compiled as normal. The \cls{standalone} class will crop the resulting output file (PDF or DVI/PS) to the content size plus a certain border. +% Page number and other header or footer material will be suppressed. +% +% For pictures drawn with TikZ a dedicated \opt{tikz} option is provided which loads the \pkg{tikz} package and also configures the \env{tikzpicture} environment to create a single cropped page. +% For PSTricks pictures an corresponding \opt{pstricks} option is provided. +% +% \par\noindent +% \begin{minipage}{\textwidth}\small +% \begin{lstlisting}[language={[latex]tex},gobble=4,frame=lines,caption={Basic use of the \cls{standalone} class.},numbers=none] +% \documentclass[tikz]{standalone} +% %\usetikzlibrary{calc} +% \begin{document} +% \begin{tikzpicture} +% \draw (0,0) rectangle (2,1) node [midway] {Example}; +% \end{tikzpicture} +% % Further 'tikzpicture' environments are possible which will create further pages. +% \end{document} +% \end{lstlisting} +% \end{minipage} +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Class options}\label{sec:classoptions} +% The \cls{standalone} class provides the following options to adjust the processing and size of the content. +% These options are removed from the normal list of class options and not passed to any loaded packages or classes like it would usually occur. +% This is also done to avoid option conflicts with identical named options of the underlying class. +% +% All boolean options take either `|true|' or `|false|' as optional values. Otherwise, if the option is used without a value, `|true|' is used. +% If not mentioned otherwise all options set to `|false|' initially. +% Options might switch other options on or off. For example, mutual exclusive options will disable each other. The order of the option is obeyed +% and later options will prevail over earlier ones. +% +% Certain class options can also be changed inside the preamble or document body using \Macro\standaloneconfig{<options>}. +% +% \DescribeKey{class}'='<class name> +% Specifies the underlying class which is loaded by the \cls{standalone} class. +% By default \cls{article} is used, which should be suitable for standalone pictures. +% In certain cases it may be from benefit to use the same class than in the targeted main document. +% For the \cls{beamer} class the special \opt{beamer} option should be used instead. +% +% \DescribeKey{crop}'=true|false' +% If enabled this option crops the content to its natural size plus a specified border. This is done by saving the content in a box register and resizing +% the page size relative to the box dimensions. +% This option is mutual exclusive with the similar \opt{preview} option and will therefore disable it. +% Also \Key{float}'=false' will be set by \Key{crop}'=true' in order to avoid issues with floating environments. +% +% \DescribeKey{preview}'=true|false' +% If enabled this option loads the \pkg{preview} package with the \opt{tightpage} option +% and wraps the content into a \env{preview} environment. This crops the content to its natural size plus a specified border. +% Issues with the \pkg{preview} options and TikZ shadings under XeLaTeX have been reported. In this cases the \opt{crop} option should be used instead. +% +% This option is mutual exclusive with the similar \opt{crop} option and will therefore disable it. +% Also \Key{float}'=false' will be set by \Key{preview}'=true' in order to avoid issues with floating environments. +% +% \DescribeKey{border}'='<length (all sides)> +% \DescribeKey{border}'='{<length (left/right)>~<length (bottom/top)>} +% \DescribeKey{border}'='{<length (left)>~<length (right)>~<length (bottom)>~<length (top)>} +% This option allows to specify the border used by the \opt{preview} and \opt{crop} options. +% The border can either be given using a single value for all sides, separately for the horizontal and vertical borders or for all sides separately. +% Multiple values are separated by spaces, which require the whole value to be wrapped in braces. +% +% This option can be changed during the document using \Macro\standaloneconfig and will affect all following pages. +% +% \DescribeKey{multi}'=true|false' +% \DescribeKey{multi}'='{<environment name>, \ldots>} +% By default the \cls{standalone} class assume that the whole content is one block which should be shown on one single page. +% If this option is activated multiple pages are supported. Each page will be cropped to its content plus the selected border (as long either \opt{preview} or \opt{crop} are enabled). +% A set of environments which hold a single page must either be given as option value or declared using \Macro\standaloneenv{<environment name>, \ldots}. +% No typeset material should be used outside such environments. +% Note that this option is enabled automatically by \Macro\standaloneenv if either \opt{crop} or \opt{preview} is enabled. +% However, it needs to be set explicitly as class option if the \opt{ignorerest} option is also set. +% If environment names are provided as option values the option is set to `|true|' and the environments are passed to \Macro\standaloneenv which is executed at the begin of the +% document environment, where all mentioned environments should be already defined. +% +% \DescribeKey{ignorerest}'=true|false' +% This option is only meaningful when both \opt{multi} and \opt{crop} are enabled. +% Then it determines if all material which does not appear inside environments declared with \Macro\standalone should be ignored or not. +% This is done by boxing and discarding all outside material. Any code will be placed inside a group and therefore local settings made between environments +% will not affect later code. Code in the preamble is not affected. +% It is recommended to keep this option disabled and only use it if really required. +% It should be noted that which \opt{preview} such material is always ignored while not affecting local settings. +% Therefore the \opt{ignorrest} option can be seen as a compatibility setting to make \opt{crop} act more like \opt{preview}, if this is required by the user. +% +% \DescribeKey{varwidth}'=true|false' +% \DescribeKey{varwidth}'='<width> +% A trailing empty line between the content and \Macro\end{document}\relax will normally create a paragraph which is \Macro\linewidth wide. +% This paragraph (or any other one) will enlarge the size of smaller pictures and display itself as a large right border. +% This option uses the \pkg{varwidth} package to wrap the content into a \env{varwidth} environment, which is based on \env{minipage}, +% but will always use the natural width of the content if it is smaller than the given maximum width. +% The resulting effect is that the created paragraph will not cause any additional width and that multiple paragraphs can be included as part of the content. +% The used maximal width (which is provided to the underlying \env{minipage} environment) is \Macro\linewidth by default, but can be set +% by provided a width as value to the option. Doing so will also switch the option on. +% +% If the \opt{crop} option is used the content is placed in restricted horizontal mode which ignores paragraph breaks. +% Using the \opt{varwidth} option paragraph breaks are enabled again. +% +% A drawback of this option is that the content will be limited to the given width, i.e.\ wider picture environment will be cropped to the width at the right +% side. In such cases either a larger width should be selected, the option be switch off, any paragraph breaks should be avoided (no trailing empty lines) or one of the +% specific picture options like \opt{tikz} or \opt{pstricks} should be used instead. +% +% This option can be changed during the document using \Macro\standaloneconfig and will affect all content of the following pages. +% +% \DescribeKey{tikz}'=true|false' +% This option declares that the content contains of one or more \env{tikzpicture} environments. This sets |multi=tikzpicture,varwidth=false| and loads the \pkg{tikz} package. +% +% \DescribeKey{pstricks}'=true|false' +% This option declares that the content contains of one or more \env{pspicture} or \env{pspicture*} environments. This sets |multi=pspicture,varwidth=false| and loads the \pkg{pstricks} package. +% Because \env{pspicture*} uses \env{pspicture} internally it is also supported. Other environments which use it as well should also be supported, +% but might also declared explicitly using \Macro\standaloneenv{<environment name>, \ldots}. +% +% \DescribeKey{beamer}'=true|false' +% If set to `|true|' this option enables a special \cls{beamer} mode, where the normal cropping is disabled. +% Instead the content is shown on a blank beamer frame. +% +% \DescribeKey{float}'=true|false' +% If this option is that to `|false|' (which is the default) any floats like \env{figure} and \env{table} environments are turned into non-floating environment. +% This is required for the options \opt{crop} and \opt{preview} to work, so these will set \Key{float}'=false' when set to `|true|' itself. +% In general it is recommended to keep floating environments inside the main document and only place the content of them into standalone files. +% This also makes it simple to include the same content in different floats of different main documents. +% +% If custom floats are defined using a package like \pkg{float} are not supported yet. Dependent on the way they define floats they might still work. +% For these \Key{float}'=true' should be set as class options so that the normal definition of floats is preserved. +% Afterwards \Macro\standaloneconfig{float=false} can be used to disable floats while taking the changed float definition into account. +% +% +% \DescribeKey{convert}'='{<conversion options>} +% \DescribeKey{png}'='{<conversion options>} +% These options allow to enable and configure the conversion feature. See \autoref{sec:convert} for the full description. +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Macros and environments}\label{sec:classmacros} +% The following macros and environments can be used inside the preamble of \cls{standalone} files. Further macros are listed in \autoref{sec:common} which are +% defined by both the class and package and can be used in standalone files but also in the main document. +% +% \DescribeMacro\standaloneconfig{<options>} +% This configuration macro accepts the class options described in \autoref{sec:classoptions}. +% It can be used inside the class configuration file to set default settings used by all standalone files, as mention in \autoref{sec:configfile}. +% These settings are set just before the class options of the standalone file are processed. +% +% Certain class options (e.g.\ \opt{border}, \opt{varwidth}) which do not have a global effect can also be changed using this macro later in the preamble or even inside the document body +% between different content if the \opt{multi} option is enabled. +% +% \DescribeMacro\standaloneenv{<environment>', '<environment>', '\ldots} +% If the \opt{multi} option is in effect this macro should be used to declare all environments which produce content. +% Common examples of such environments are \env{tikzpicture}, \env{pspicture} and other picture environments. +% This macro must only be used inside the preamble. +% Every use of such an environment in the document body will produce a new page. +% An exception are nested appearances of such environments, e.g.\ a \env{tikzpicture} inside a node of another \env{tikzpicture}. +% The environments must be previously defined and must not be redefined afterwards. Multiple appearances of the same environment name +% inside one or multiple \Macro\standalonenv should be avoided. +% +% This macro uses \Macro\PreviewEnvironment internally if the \opt{preview} option is active. Own code is used with the alternative \opt{crop} option. +% If none of these options are enabled this macro will have not effect and will be silently ignored. +% +% \DescribeMacro{\standaloneignore} +% In rare cases some code must be placed before the |\documentclass| of a sub-file (e.g.\ |\PassOptionsToPackage|). +% Because the main document will only skip code between |\documentclass| and |\begin{document}| this code will be executed by it. +% In order to avoid this the macro \cs{standaloneignore} can be used at the very beginning of a sub-file to skip over this code. +% However it must be written as |\csname standaloneignore\endcsname| to avoid a `Undefined control sequence' error when compiled standalone. +% After all the class is not loaded at this point, therefore no \cls{standalone} macros are yet defined. +% The |\csname|\,\ldots|\endcsname| construct will simple make it equal to |\relax| in this case. +% +% Please note that all code before |\documentclass| is not processed by any of the \opt{subpreamble} options but always simply removed. +% This macro was inspired by the similar macro |\docmute| of the |docmute| package. % -% When the sub-file is compiled on its own the |\documentclass| and |document| environment will be active as normal. The main file, however, -% will skip everything from the |\documentclass| till the |\begin{document}|. The (now fake) |document| environment is redefined to be a simple -% TeX-group. Any code after the |\end{document}| will be ignored. The real |document| environment of the main file will be unaffected and will work as normal. +% \DescribeEnv[<sub-file content>]{standalone} +% The \env{standalone} environment is automatically wrapped around the content of standalone files. +% If the \opt{multi} option is enabled it is wrapped around every page, i.e.\ every environment declared with \Macro\standaloneenv. +% The definition of this environment depends on options like \opt{crop} and \opt{preview}. +% It is possible to redefine this environment in the configuration file or the document preamble to adjust the processing of the content, but this is not recommended. +% If done most content related options will stop work and/or cause errors. +% +% The beamer specific macros and environments are described in \autoref{sec:beamer}. % -% Instead of transferring the packages required by each sub-file manually to the main document preamble, this task can be automatised using -% the options listed in section~\ref{sec:pkgoptions} % -% \subsection{Class Options} -% The |standalone| class will load a real document class.\optpar{class} By default this is |article|. The document class normally has not much -% influence on sub-files like pictures, especially when the \pkg{preview} package is active. However, the used class can be adjusted by the user -% with the |class=|\meta{class name} option. +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Support for Beamer Presentations}\label{sec:beamer} +% Presentation can be written in \LaTeX\ using the \cls{beamer} class. Each presentation frame is wrapped in a \env{frame} environment. Overlay effects +% can be added using special macros. This effects result in multiple pages per frame. Pictures with such overlay effects can not be +% compiled standalone using the normal settings. Instead the \cls{standalone} class must load the |beamer| class and wrap the content also in +% a \env{frame} environment while skipping the \env{preview} environment. To activate this settings load the \cls{standalone} class with the |beamer| option. +% Because the \env{frame} environment is quite special (it normally collects all it's content and calls the \cs{frame}) and must also support +% verbatim content it is not easily possible to redefined the |document| environment to include \env{frame}. Also \env{frame} accepts options which |document| doesn't. +% Therefore a second environment called \env{standaloneframe} is used in the beamer picture files. It will be equal to \env{frame} in standalone mode, but +% without effect otherwise. % -% The boolean \opt{preview}\optpar{preview} option can be used to disable the use of the \pkg{review} package. The default is |preview=true|. The package is not loaded if |preview=false| is set. -% The preview border can be set using the \opt{border}\optpar{border} option. This border will be added to the file content. -% The usage is either \MacroArgs'border='{<left>~<lower>~<right>~<upper>}, \MacroArgs'border='{<left/right>~<lower/upper>} or \MacroArgs'border='<all sides>. -% The default unit is |bp| (big points) which is the unit used by the PostScript and PDF formats. If |preview=false| is set this option will be ignored. +% \DescribeMacro{\ifstandalonebeamer} +% Both the class and the package provide the if-switch \cs{ifstandalonebeamer}, which can be used to only include code if the file is +% compiled standalone with the |beamer| class option set. +% The switch is set to \cs{iftrue} by the class when loaded with the \opt{beamer} option and always to \cs{iffalse} by the package. +% It can be used to place beamer specific options in the configuration files, which should be skipped for non-beamer standalone files. +% If used inside the configuration file this switch must be placed inside \Macro\AtEndOfClass{\ldots}, because the \opt{beamer} option is not yet processed % -% A special \opt{beamer}\optpar{beamer} option is provided to handle beamer frames and overlays correctly.

Because this file will be overwritten every time the bundle is updated, users +% should create an own configuration file in the local TEXMF tree or the document directory. In order to keep the default behaviour this file should either contain the content of the bundle configuration file +% or load it. +% Because it can be assumed that the bundle configuration file resides inside a \file{standalone} directory, therefore it can be loaded from a user configuration file using +% \Macro\input{standalone/standalone.cfg}. +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Conversion to images}\label{sec:convert} +% Using the \opt{convert} class option the standalone file can be easily converted to an raster image.

By default the two following tools are supported and either of them must be installed in order to use the conversion feature. +% In order for an external program to be executed the \texttt{-shell-escape} option\footnote{Maybe named differently depending on the used \LaTeX\ distribution} must be used for the +% compiler executable, e.g.\ \texttt{pdflatex -shell-escape filename}. Without this option no conversion is possible. +% +% By default the conversion program of \href{http://www.imagemagick.org/}{Image Magick} is used for PDF \LaTeX\ files, which is freely available for Unix/Linux, Mac and MS Windows. +% Under Ubuntu Linux it can be installed using the shell command `\texttt{sudo apt-get install imagemagick}'. +% The conversion executable is simply called `|convert|'. However, there is another program with the same name provided by MS Windows itself which +% converts old FAT filesystems to NTFS! It has been suggested to rename the Image Magick executable to `|imgconvert|' instead. +% By default \cls{standalone} uses `|imgconvert|' as executable if MS Windows is detected and `|convert|' otherwise. +% The executable name can be change manually using the `|convertexe|' conversion option or by using +% \codeline{\AlsoMacro\standaloneconfig{'convert='{'convertexe='{convert}}}} +% in the configuration file `|standalone.cfg|'. +% +% Another conversion program is \href{http://pages.cs.wisc.edu/~ghost/}{Ghostscript} which is a very common PostScript interpreter which also supports PDF. +% It is used by default for DVI/PS files. +% Under Ubuntu Linux it is most likely already installed but otherwise can be installed using `|sudo apt-get install ghostscript|' or +% `|sudo apt-get install gs|'. +% It can convert both to various output formats and is freely available for Unix/Linux, Max OS X and MS Windows. +% It requires to set the correct output device which is not always fully identical to the output format (e.g.\ `|png16m|' for a PNG (with 16 million colors)). +% The devices for PNG and JPG are already configured. +% Other devices can be configured using the \Key{defgsdevice}'='{<.extension>}{<device>} conversion setting. +% The Ghostscript executable is usually named `|gs|' under Linux/Unix and `|gswin32c|' under MS Windows and configured this way by default, +% but this may be changed using the |gsexe| setting. +% +% +% \subsubsection{Conversion process} +% The conversion process is currently implemented in the following way to allow the normal compilation and subsequent conversion using only one (manual) compiler run. +% Because the document must be fully compiled before the conversation can occur the \cls{standalone} executes the same \LaTeX\ compiler (e.g.\ texttt{pdflatex}) again as +% a sub-process which compiles the current document fully. This is done when the \cls{standalone} class is loaded, so that the main compiler instance is still at \Macro\documentclass +% and has not yet itself opened the output file for writing. After the document got compiled using the sub-process the external conversion tool will be executed. +% If required intermediate conversions like \texttt{dvips} are also executed beforehand. +% Finally the main compiler run is terminated without producing any output, keeping the output file generated by the sub-process intact. +% A drawback of this implementation is that the log file created by the sub-process is overwritten by the main process and does not hold meaningful information. +% This can be compensated by setting a different jobname for the sub-process using the \Key{subjobname} conversion setting. +% +% \subsubsection{Conversion examples} +% +% PDF/PS is rastered with 600x100dpi and then converted to JPG:\\*[\smallskipamount] +% | \documentclass[convert={density=600x100,outext=.jpg}]{standalone}| +% +% \par\medskip\noindent +% Produces BMP with 400x400px (one side might be meder if content is not quadratic in shape):\\*[\smallskipamount] +% | \documentclass[convert={outext=.bmp,size=400}]{standalone}| +% +% \par\medskip\noindent +% Produces TIFF G4 output file using Ghostscript with a density of 72dpi:\\*[\smallskipamount] +% | \documentclass[convert={ghostscript,gsdevice=tiffg4,|\\* +% | outext=.tiff,density=72}]{standalone}| +% +% \par\medskip\noindent +% Produces PNG (default) with a size of 640px (suitable to be uploaded on StackExchange sites without the image getting downscaled):\\*[\smallskipamount] +% | \documentclass[convert={size=640}]{standalone}| +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% +% \subsection{Simple TeX File} +% A simple \file{standalone.tex} file is provided together with the bundle, which may be useful in special occasions. +% It will set the \cs{ifstandalone} switch to \emph{true} when compiled standalone but to \emph{false} +% when loaded after any |\documentclass| macro, as long the switch isn't defined yet. +% It must be used if this switch is required before the |\documentclass| of a standalone file. +% +% \noindent +% \begin{minipage}{\textwidth}\noindent\small +% \begin{lstlisting}[language={[latex]tex},gobble=4,frame=lines,numbers=none,caption={Usage of 'standalone.tex'.}] +% \input{standalone} % use before any '\documentclass' +% \ifstandalone +% % Used only if compiled standalone +% \fi +% \end{lstlisting} +% \end{minipage} +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{FAQ / Troubleshooting}\label{sec:classfaq} +% This section expands some issues and their solution which can arise with the \cls{standalone} class. +% +% \subsubsection*{Large white space / border at the right side} +% A large white space / border on the right side occurs when the content is placed inside a paragraph. +% This causes the content to be \Macro\linewidth wide and so smaller pictures will contain now a white space at the right. +% A common cause for this is that there was is a empty line between the content and \Macro\end{document} which causes a paragraph break. +% +% This issue can be solved by either removing any trailing lines or other paragraph breaks, or by using the \opt{varwidth} option which suppresses the extra added width. +% It is also possible to use the \opt{multi} option and \Macro\standaloneenv{<environment name>} to declare certain environments as page content. +% The \opt{tikz} option does this for \env{tikzpictures} and the \opt{pstricks} option for \env{pspicture}. See the descriptions of these options for more details. +% +% \subsubsection*{Some amount of the content on the right side is missing} +% If the content is cropped to much on the right side, check if the \opt{varwidth} option is used. In this case the used maximum width (\Macro\linewidth by default) is too small. +% A larger width can be set using \hbox{\opt{varwidth}\MacroArgs'='<length>} or the option can be disabled altogether using \hbox{\opt{varwidth}|=false|}. +% The largest width possible is given by \Macro\maxdimen, which however might cause internal overflows. +% +% This can also be caused with \cls{beamer} content (i.e.\ when the \opt{beamer} option is used). In this case no cropping or \env{varwidth} environment is used at all, +% but the content is simply to large to fit on a \cls{beamer} \env{frame}. To avoid this rescale the content to do fit. This can be realised by either using +% scaling facilities of the used picture environment (like |scale| with \env{environment}, but this only scales coordinates) or using \Macro\scalebox or \Macro\resizebox from \pkg{graphicx}. +% For complicated code which contains verbatim or other catcode changing code either the \Macro\Resizebox from the \pkg{realboxes} package +% or the \MacroArgs{adjustbox}{scale=<factor>} environment from the \pkg{adjustbox} package should be used. +% +% \subsubsection*{A multi-page document contains some pages with unwanted content} +% This is caused while \opt{multi}|=true| and \opt{crop}|=true| are set but \opt{ignorerest}|=false| \emph{and} the document contains +% typeset material outside of environments declared with \Macro\standaloneenv. To avoid that this extra material should be removed or \opt{ignorerest} should be set to |true|. +% This will also ignore all settings inside the document body which are not inside a declared environment. These can be moved to the preamble instead. +% See the description of the \opt{ignorerest} option for more details. +% +% \subsubsection*{In a multi-page document using DVI/PS mode all pages except the first have a vertical offset} +% The vertical reference points in PostScript could does not change when the pages are resized to fit the individual content of every page. +% Therefore an offset is added to compensate for this, which shifts the content to the appropriate vertical position. +% Should this not work as expected please inform the package author and provide a small example which causes this issue, together with the version number of the used |latex| compiler and tools (like |dvips|, |ps2pdf|) +% as well as the used \cls{standalone} bundle. +% +% \subsubsection*{Issues with cropped files in DVI mode} +% The \opt{crop} option uses PostScript commans in DVI mode, i.e.\ when |latex| not |pdflatex| (or others) is used as a compiler. +% This PostScript commands will only work once the DVI is converted to PS or EPS. +% Currently this cropping code is experimental and might not produce a full (E)PS standard compatible file. +% This can lead to wrong bounding boxes and wrong orientations or, dependent on the used PostScript tool, even to PostScript compiler errors. +% Some issues can be overcome by converting the the (E)PS file to a (more) standard compatible version using tools like |eps2eps| or Ghostscript. +% +% \subsubsection*{Errors ``Float(s) lost'' or ``not in outer par mode''} +% Floating environments like \env{figure} or \env{table} can not be used while \Key{float}'=true' and either \Key{crop}'=true' or \Key{preview}'=true' is set. +% The last two options will try to store the float into a box which is not allowed (because it can't the float any longer). +% Usually \Key{float}'=false' will solve this error, because it turns these environments into non-floating alternatives. +% Because both the \Key{crop} and \Key{preview} option will set \Key{float}'=false' themselves, this issue can only arise when the \Key{float} option is manually set afterwards. +% +% \subsubsection*{Image conversion does not work} +% In order for the image conversion to work an external conversion software must be installed. By default either Image Magkick or GhostScript is used. Please insure that either or both of these softwares are installed. +% Installation guide for your operating system should be easily available on the Internet. The \LaTeX\ compiler option |-shell-escape| must be used to allow this external software to be executed from within the \LaTeX\ code. +% If this two points are fulfilled but the conversion does still not work, please check the log file. The lines in question start with `|runsystem|' (at least with \TeX\ Live 2011). +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \clearpage +% \section{Usage of the \pkg{standalone} package} +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Basic usage} +% The \pkg{standalone} package needs simply be loaded using \Macro\usepackage in a main document. It redefines the \Macro\documentclass macro, which can occur in sub-files, +% so that it ignores anything till the next \Macro\begin{document} and then takes the \env{document} environment as a simple group. The real \env{document} environment in the main file is not +% affected. Sub-files can then be included in the main document body using \Macro\input{<filename>}. +% +% The \pkg{standalone} package must not be loaded before the document class using \Macro\RequirePackage, because this will cause issues. +% Also it is not possible to \Macro\input\relax standalone files inside the preamble, e.g.\ as part of a \Macro\savebox assignment. +% +% It is possible to cascade \cls{standalone} files, i.e. \Macro\input\relax a \cls{standalone} file from within a \cls{standalone} file. Then both the \cls{standalone} class and the \pkg{standalone} +% package must be loaded by the any parent \cls{standalone} file. These parent files can still be used inside other \LaTeX\ documents if these load the \pkg{standalone} package themselves. +% +% See \autoref{sec:pkgoptions} for a list of package options which enable further features. +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Package options}\label{sec:pkgoptions} +% The following options are supported by the \pkg{standalone} package. +% Most of them are boolean options which take either `|true|' or `|false|' as optional values. If such an option is used without a value, `|true|' is used. +% If not mentioned otherwise all options set to `|false|' initially. +% Options might switch other options on or off. The order of the option is obeyed and later options will prevail over earlier ones. +% Note that some older versions of the \pkg{standalone} package only take the option without any value. +% +% \DescribeKey{subpreambles}'=true|false' +% The \cls{standalone} package removes all sub-file preambles (``sub-preambles'') by default when loaded. +% However, if the package is loaded with the \opt{subpreambles} options, all sub-preambles are stored in an auxiliary file with the name `\meta{main tex file name}|.sta|' (for \emph{sta}ndalone). +% This file is then loaded or processed at the beginning of the next \LaTeX\ run (i.e.\ at the place in the preamble where the \cls{standalone} package is loaded). % The way how the \opt{subpreambles} option works can be controlled by the options \opt{sort}, \opt{print} and \opt{comments}/\opt{nocomments}. % Please note that the \opt{sort} and \opt{print} options require of course the \opt{subpreambles} option and will enable it if not already done so. % +% \DescribeKey{sort}'=true|false' % With only the \opt{subpreambles} option set, the sub-preambles are simple read and executed unchanged.

Further macros are listed in \autoref{sec:common} which are +% defined by both the class and package and can be used in standalone files but also in the main document. +% +% \DescribeMacro\standaloneconfig{<options>} +% This configuration macro accepts some of the package options described in \autoref{sec:pkgoptions}. These options are \opt{group}, \opt{mode}, \opt{extension} and \opt{build}, +% which can be changed for different included standalone files. +% +% If both the \pkg{standalone} class and package is used together this macro can also be used to set the class options as described in \autoref{sec:classmacros}. +% +% \DescribeMacro\includestandalone[<options>]{<file>} +% This sophisticated macro can be used instead of \Macro\input\relax to include standalone files. Its behaviour is controlled by the \opt{mode} package option. +% This macro can either include the source code in the same way as \Macro\input\relax (\Key{mode}'=tex'), include the output file (PDF, EPS) using \Macro\includegraphics\relax +% (\Key{mode}'=image'), try first the output file and use the source file if it is available (\Key{mode}'=image|tex'), +% build the output file from the source file either always (\Key{mode}'=build'), only if the image files does not exist (\Key{mode}'=buildmissing') +% or only if the source file is newer (\Key{mode}'=buildnew'). +% See also the \autoref{sec:build} for further details. +% +% The \meta{file} argument must be the file name of the standalone source file \emph{without} the extension. The macro accepts the same \meta{options} as \Macro\includegraphics as well +% as any options suitable for \Macro\standaloneconfig. This means that the source file can also be resized and rotated in `|tex|' mode like an image. +% TODO: In this mode the package also tries to extract and apply the class options from the standalone file and apply these to the included source. +% Unfortunately, it can not be fully guaranteed that the standalone content will be displayed identical in source code and image mode. Some settings might not be applied +% in the same way and rounding differences may occur. +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Building images from standalone files}\label{sec:build} +% Using the \Macro\includestandalone macro standalone files can be either included directly as source files or as vector graphic images which are build from these. +% The \pkg{standalone} package provides the feature to automatically build image files from given standalone source files. +% This is controlled by the \opt{mode} options. This was already described in \autoref{sec:pkgoptions} and~\ref{sec:pkgmacros}. +% +% This enables the user to switch easily between including source code or images, either globally or only for selected standalone files. +% Using images has the benefit that the included material, often complicated pictures, does not have to be recompiled every time with the main document. +% This leads to significant speed improvements. The drawback is a slight increase in file size, because the material will have its own file headers. +% Also any settings done in the main document which would affects the source code will not have an effect on the image. This can be positive or negative dependent on the case. +% +% An extended feature is the automatic building of images from the standalone files, either always or only if the source files are newer than the existing image files. +% In this cases the \Macro\includestandlone macro will call the \LaTeX\ compiler on the standalone files in question to produce the images, then include these using \Macro\includegraphics. +% This requires the `|-shell-escape|' compiler option to be set, otherwise the execution of shell commands is disabled for security reasons. +% +% The image files will normally be created in the current directory of the main document, which is not necessarily the same directory where the source files are located. +% Dependent on the used compiler settings, files in the current directory will be found first before other directories are searched. +% Using \Key{mode}'=buildnew' newly build image files placed in the current directory will therefore taken before older images files potentially located in the directory of +% the standalone files. Because the exact directory of source files is not accessible within \LaTeX\ documents, it is not possible to create the images files always in the same directories +% as the source files. Compiler options like `|-output-directory|' can be useful to influence the output directory of the build images. However, these options must be used with the +% internal compiler run, i.e.\ by setting \Key{build}'='{'latexoptions='<...>} appropriately, not (only) on the main \LaTeX\ compiler run. +% +% If the build process fails a warning is issued and the source code will be included instead. It should be noted that failure detection is not perfect and might lead to false positives or negatives. +% +% \begin{table} +% \makeatletter +% \def\showbuildvar#1{{% +% \expandafter\let\expandafter\@tempa\csname sa@build@#1\endcsname +% \@onelevel@sanitize\@tempa +% \texttt{\@tempa} +% }}% +% \makeatother +% \belowcaptionskip=\abovecaptionskip +% \caption{Build settings}\label{tab:buildsettings} +% \hbox to \textwidth{\hss% +% \begin{tabular}{>{\ttfamily}lp{\dimexpr.45\textwidth\relax}l} +% \toprule +% \multicolumn{1}{l}{Build setting} & Description & Default value \\ +% \midrule +% latex & \LaTeX\ compiler to be used & Same as main compiler \\ +% latexoptions & Command line options for compiler & \scriptsize\showbuildvar{latexoptions} \\ +% jobname & Jobname for build compiler run & \scriptsize\showbuildvar{jobname} \\ +% command & Full build shell command & \scriptsize\showbuildvar{command} \\ +% postcommand & Command executed after main command, to produce final output file & \scriptsize\texttt{dvips -o '\textbackslash file.eps' '\textbackslash file.dvi'} \normalsize (DVI mode only)\\ +% \bottomrule\noalign{\smallskip} +% \multicolumn{3}{l}{% +% \strut Note: the settings (except `\texttt{command}' and `\texttt{postcommand}') can also be used as macros in other settings. +% }\\% +% \multicolumn{3}{l}{% +% \strut The given file name is available (without extension) as \texttt{\textbackslash file}. +% }% +% \end{tabular} +% \hss} +% \end{table} +% +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \section{Common macros}\label{sec:common} +% The following conditional macros are defined by both the \cls{standalone} class and package, but react differently when the code is compiled standalone or as part of a main document. % -% \bigskip % \DescribeMacro{\ifstandalone} % Both the class and the package provide the if-switch \cs{ifstandalone}, which can be used to only include code if the file is % compiled standalone.
