From the user's point of view, the % package allows to insert in an comfortable way any \TeX{} material % into separate layer in PDF document and insert links which toggle % this layer on/off. Hence parts of PDF document like formatted text, % tables, math formulas or graphics can be turned to visible or % invisible state by clicking active links or buttons. % % Similar packages are |cooltooltips|, |pdfcomment|, |AcroTeX| and % |fancytooltips|. In contrast to |cooltooltips| and |pdfcomment|, we % can work with any \TeX{} material, not only plain text. In contrast % to |fancytooltips|, no external file is necessary and more % minilayers (see below) can be opened simultaneously on one % page. However, |fancytooltips| and |ocgtools| can be combined in the % same document, even on the same page. |AcroTeX| has far more % possibilities than |ocgtools|, but has three disadvantages: (1) % limited support for |pdftex| (no layers with |pdftex| driver) (2) % PDF file needs postprocessing (3) for the post-processing the non-free % Adobe Acrobat Professional is necessary. However, the user of % |ocgtools| must have |AcroTeX| installed, since we use its % capability to insert buttons and JavaScripts into document (|eforms| % and |insdljs| packages). % % Two types of OCG objects can be inserted % \begin{itemize} % \item \textit{layers}: OCG's which span across the whole size of paper % (scaled if necessary) % \item \textit{minilayers}: OCG's which have their natural size and % are placed somewhere close to the link which toggles them on/off. % \end{itemize} % % The user should use viewer which allows to hide/reveal layers by % JavaScript. This includes especially Adobe Reader. Some limited % functionality is also in Foxit Reader (see the option |nobutton| % below). In some other viewers (like |xpdf|) users see red warning on % the first page (see |\ocgtools@msg|), all layers are visible and % cannot be hidden. % % \marginpar{\texttt{Important comment!}}\textbf{\color{red} Big % warning:} Unfortunately, with this package you may make your PDF % files \textbf{less portable} even if you use Adobe Reader! Till now, % we observed the following problems: % \begin{itemize} % \item jpg pictures may look darker when using \texttt{transparent} % option and \textbf{Linux} version of Adobe Reader -- Adobe Reader % switches to different rendering method which seems to be system % dependent. Hope, Adobe fixes this problem soon. % \item The layer with initial message on the first page which should % be hidden to the users of Adobe Reader is sometimes still visible, % if the PDF file is opened in Internet browser. From this reason, % layer \texttt{ocgtools0} is switched on and then off when % initializing PDF document. Hope, this workaround solves the % problem. If not, report the problem with a minimal example, please. % \end{itemize} % % \section{Examples} Several examples are distributed with the % package. We have one minimal example, one example which shows % cooperation with |preview.sty| and mainly -- examples which show % cooperation with three most popular packages to build % presentations. This includes |web.sty|, |pdfscreen.sty| and % |beamer.cls|. We have three demo files for each -- with no panel, % with panel on the right and with panel on the left. All examples can % be recompiled by running |ocgtools-test.bat| on Windows and % |ocgtools-test.sh| on Linux. % % \section{Usage} % % All the packages we use are on CTAN or in \TeX live2009. The file % |ocg.sty| is a part of |asymptote| package\footnote{Do not % interchange with the |ocg.sty| provided by \"Osterreichische % Computer Geselshafft. The correct file |ocg.sty| is at % \url{http://www.tug.org/svn/texlive/trunk/Master/texmf/tex/latex/asymptote/ocg.sty}}. % |AcroTeX| is quite old on CTAN but the version on CTAN works well. % New version of |AcroTeX| is at |www.acrotex.net|, if necessary. % % \bigskip \textbf{Prerequisities}: Only |pdflatex| is supported. The % route via |dvips| or |dvipdfm| is not (yet?) supported (this % restriction follows from |ocg.sty| and |transparent.sty| % packages). To work with the package load |color.sty| and % |hyperref.sty| packages. (This is usually done automatically by most % packages which are used to build PDF presentations. If not, these % packages are loaded by |ocgtools| automatically as soon as % |\definecolor| and |\href| remain undefined, respectively.) You may % use also |xcolor.sty|, but this package is not compatible with % |transparent| option. \bigskip % % You have to compile your |.tex| file \textit{three times} (!). If % you change your document and create new layer, you have to compile % three times again. After most changes (which include change in % position of but not the number of layers) you have to compile twice % to put layers on correct position. If you change the content of text % layers or minilayers, one compilation is sufficient. % % \bigskip % Load package |ocgtools.sty| as usual: % \cs{usepackage}\oarg{options}|{ocgtools}|. Options include: % \begin{description} % \item[\texttt{transparent}] Layers in fact do not span over the % whole page, but the material of layer is scaled to some reasonable % size (we keep aspect ratio). If the layer is activated, the page % is covered by a uniform color |ocgbg| and the layer is placed on % the top. The options |transparent| makes the color |ocgbg| % transparent. Looks cool, but it could be slow and could change % some colors of bitmap pictures (and this behavior seems to be % system dependent -- looks differently on Linux and differently on % Windows). The transparency is achieved by putting the command % |\ocgtools@transparent| on appropriate place. The default setting % is |\def\ocgtools@transparent{\transparent{0.4}}|. Use something % like % like the following three lines to override:\\ % |\makeatletter|\\ % |\def\ocgtools@transparent{\transparent{0.6}}|\\ % |\makeeatother| % \item[\texttt{nobutton}] The pages with active layers have a % transparent button which can be used to hide this layer. The user % simply clicks anywhere and the layers become hidden. In some % viewers (like Foxit Reader) the button is not 100\% transparent. % This option allows not to include the big button to hide layers. % The layers can be closed by clicking the red cross % below. % \item[\texttt{insertvisible}] In some rare cases problems with OCG's % occur on Windows installation of \TeX. Temporary (I hope) % workaround is to use this option, which inserts OCG's as visible. % The visibility is turned off when the PDF is opened on the first % page. % \item[\texttt{mouseover}] Layers can be opened by MouseOver action. % The corresponding active area is an invisible square with side 8pt % placed on the right bottom corner of the text or picture which % opens the layer. More details: MouseOver opens the layer and % MouseExit hides this layer again. If mouse button is clicked, the % layer remains opened after exiting the button. % \item[\texttt{minimouseover}] As mouseover, but restricted to % minilayers. % \item[\texttt{noocg}] The package and its commands are ignored. % \item[\texttt{noprogressmsg}] Opening PDF on the first page show the % message related to initial processing layers. This option turns % the message off. % \item[\texttt{nopageclose}] By default, all layers become off and % all buttons become hidden if the page is changed. The option % \texttt{nopageclose} suppresses this behavior. % \end{description} % % The macro |\ocgtext|\oarg{width}\marg{text1}\marg{text2} % \DescribeMacro{\ocgtext} is used to create layer which contains any % \LaTeX{} material. \meta{text1} is a text which is written in an % ``usual'' way (in blue color which indicates that this text can be % used to hide/unhide another object) and this text is used to % hide/unhide layer with \meta{text2} (which could be text divided % into more than one paragraph, figure created by |mfpic| or any % \LaTeX{} material). \meta{text2} is either placed into |\hbox| (if % \meta{width} is 0\,pt, which is default) or wrapped by |\vbox| with |\hsize| % equal to \meta{width} (in the opposite case). % % % % \DescribeMacro{\ocgpicture} The macro % |\ocgpicture|\oarg{params}\marg{picture} is used to insert a picture % which is used as a link to layer with bigger version of this % picture. The optional parameter \meta{params} is used by % |\includegraphics| command to draw picture in text. The layer % contains scaled version of the picture (aspect ratio is preserved). % % \DescribeMacro{\ocgminitext} The macro % |\ocgminitext|\oarg{width}\marg{text1}\marg{text2} is used to create % layer containing \meta{text2} which is placed near the right top % corner of \meta{text1}. \meta{text2} is placed into |\hbox| or % |vbox| with given |hsize| according to the value of \meta{width}, % as has been explained at |\ocgtext| macro. Macros |\ocgminitextrb|, % |\ocgminitextlt| and |\ocgminitextlb| can be used to place the % minilayer to the right bottom, left to and left bottom corner. % % \DescribeMacro{\ocgtextstart}\DescribeMacro{\ocgtextend} Macros % |\ocgtextstart| and |\ocgtextend| are used to denote the start and % the end of hyperlink which is used to hide/reveal layers. Default % setting is |\def\ocgtextstart{\color{blue}}| and |\def\ocgtextend{}| % and hence, the links are blue and there is no mark at the end of the % link. % % \DescribeMacro{ocgpaper}\DescribeMacro{ocgbg} The colors |ocgbg| and % |ocgpaper| are used to set the colors which are used to hide page % and color which is used as background for text produced by % |\ocgtext| and |\ocgminitext| commands. The default setting is % |\definecolor{ocgpaper}{rgb}{1,1,0.2}| and % |\definecolor{ocgbg}{rgb}{0,0,0}|. % % \DescribeMacro{\layerHshift} \DescribeMacro{\layerVshift} The % dimensions |\layerHshift| and |\layerVshift| are used to place % layers exactly on the top of the page. If presentation packages % |web|, |beamer| or |pdfscreen| are used, then the length is set % automatically. % % \DescribeMacro{\ocgtools@shipoutstart@hook} % \DescribeMacro{\ocgtools@shipoutend@hook} Commands % |\ocgtools@shipoutstart@hook| and |\ocgtools@shipoutend@hook| are % introduced to insert some material at the begin and at the end of % the box with the page contents. Can be used for example to put % background to the presentation. Both commands should produce boxes % of zero dimensions, i.e. use something like \begin{verbatim} % \makeatletter \def\ocgtools@shipoutstart@hook{\hbox to 0 pt{\kern % -1in \Huge A\hss}} \makeatother \end{verbatim} to insert letter "A" % into the left bottom corner. Note that you will see this letter only % if the background of the presentation is transparent. See also the % files |ocgtools-example-web*.tex| and |ocgtools-example-web*.pdf| % for slightly more complicated background. % % \DescribeMacro{\ocgclosechar} \DescribeMacro{\ocgtools@msg} Macro % |\ocgclosechar| is used to print mark which is used to close layers % and minilayers and |\ocgtools@msg| contains string for users of % viewers which do not support layers (see the first few lines of the % code for default settings). % % \section{Possible future development and known problems} % \begin{enumerate} % \item Test and support more packages for slides than current % web.sty, pdfscreen.sty and beamer.sty? Which ones? % \item Using |preview| package it is possible to extract equations % and figures from the document and redefine |\ref| and |\eqref| % commands in such a way that clicking (or mouseover) opens on the % current page the layer with this equation (figure) and shift % clicking moves the user to the page with this equation % (figure). Or would |fancytooltips| produce better results in this % case (smaller PDF file)? See also the paper by Ross More at % \url{http://www.tug.org/TUGboat/Articles/tb29-3/tb93moore.pdf}. See % the |ocgtools-preview.*| files for some initial attempts in this % direction. % \item Introduce draft mode, which prints all layers at the end of % document with links there and back? % \item Improve placement of minitextlayers. Currently we have one the % reference point for both minitextlayers aligned to top and % bottom, which is far from optimal. % \item In some rare cases the layers may be not inserted properly % when the \LaTeX{} file is compiled on \textbf{Windows} -- see the % option \texttt{insertvisible} which solves this problems in most % cases. Since the author has limited access to \TeX{} % installations on Windows and hence reporting of problems with a % minimal example is highly appreciated. % \item The package cannot be used to hide 3D graphics inserted by % |movie15| package. However, you can put this graphics into % floating window or full-screen using capabilities of Acrobat Reader % 9. % \item If you open and close layer and then use "Back" % (Alt+LeftArrow), the layer opens again, but the button to hide % this layer becomes unavailable. Possible solution is to define % open action and close action for each layer (is it possible in % current PDF specification?). % \end{enumerate} % % \StopEventually{} % % \section{Implementation} % Initial settings % \begin{macrocode} %<*package> \def\ocgtools@msg{If message does not disappear after a short time, the author either did not compile the \LaTeX{} file three times, or your PDF viewer does not support OCG.
