Much of the information presented in the following is not -really special to \beamer, but applies to any other document class as well. - - -\subsection{Including External Graphic Files Versus Inlines Graphics} - -There are two principal ways of creating \TeX-documents that include -graphics: Either the graphic resides in an external file that is -\emph{included} or the graphic is \emph{inlined}, which means that -\TeX-file contains a bunch commands like ``draw a red line from -here to there.'' In the following, the advantages and disadvantages of -these two approaches are discussed. - -You can use an external program, like |xfig| or the Gimp, to create a -graphic. These programs have an option to \emph{export} graphic files -in a format that can then be inserted into the presentation. - -The main advantage is: -\begin{itemize} -\item - You can use a powerful program to create a high-quality graphic. -\end{itemize} - -The main disadvantages are: -\begin{itemize} -\item - You have to worry about many files. Typically there are at least - two for each presentation, namely the program's graphic data file and the - exported graphic file in a format that can be read by \TeX. -\item - Changing the graphic using the program does not automatically change - the graphic in the presentation. Rather, you must reexport the - graphic and rerun \LaTeX. -\item - It may be difficult to get the line width, fonts, and font sizes - right. -\item - Creating formulas as part of graphics is often difficult or - impossible. -\end{itemize} - -You can use all the standard \LaTeX\ commands for inserting graphics, -like |\includegraphics| (be sure to include the package -|graphics| or |graphicx|). Also, the |pgf| package offers commands for -including graphics. Either will work fine in most situations, so -choose whichever you like. Like |\pgfdeclareimage|, -|\includegraphics| also includes an image only once in a |.pdf| file, -even if it used several times (as a matter of fact, the |graphics| -package is even a bit smarter about this than |pgf|). However, -currently only |pgf| offers the ability to include images that are -partly transparent. - -At the end of this section you will find notes on how to include -specific graphic formats like |.eps| or |.jpg|. - -\lyxnote -You can use the usual ``Insert Graphic'' command to insert a graphic. - -The commands |\includegraphics|, |\pgfuseimage|, and |\pgfimage| are -overlay-specification-aware in \beamer. If the overlay specification -does not apply, the command has no effect. This is useful for creating -a simple animation where each picture of the animation resides in a -different file: - -\begin{verbatim} -\begin{frame} - \includegraphics<1>[height=2cm]{step1.pdf}% - \includegraphics<2>[height=2cm]{step2.pdf}% - \includegraphics<3>[height=2cm]{step3.pdf}% -\end{frame} -\end{verbatim} - - -A different way of creating graphics is to insert -graphic drawing commands directly into your \LaTeX\ file. There are numerous -packages that help you do this. They have various degrees of -sophistication. Inlining graphics suffers from none of the -disadvantages mentioned above for including external graphic files, -but the main disadvantage is that it is often hard to use -these packages. In some sense, you ``program'' your graphics, which -requires a bit of practice. - -When choosing a graphic package, there are a few things to keep in -mind: -\begin{itemize} -\item - Many packages produce poor quality graphics. This is especially true - of the standard |picture| environment of \LaTeX. -\item - Powerful packages that produce high-quality graphics often do not - work together with |pdflatex|. -\item - The most powerful and easiest-to-use package around, namely - |pstricks|, does not work together with |pdflatex| and - this is a fundamental problem. Due to the fundamental differences - between \textsc{pdf} and PostScript, it is not possible to write a - ``|pdflatex| back-end for |pstricks|.'' -\end{itemize} - -A solution to the above problem (though not necessarily the best) is -to use the \textsc{pgf} package. It produces high-quality graphics and -works together with |pdflatex|, but also with normal -|latex|. It is not as powerful as |pstricks| (as pointed -out above, this is because of rather fundamental reasons) and not as -easy to use, but it should be sufficient in most cases. - -\lyxnote -Inlined graphics must currently by inserted in a large \TeX-mode -box. This is not very convenient. - - -\subsection{Including Graphic Files Ending \texttt{.eps} or \texttt{.ps}} - -External graphic files ending with the extension |.eps| (Encapsulated -PostScript) or |.ps| (PostScript) can be included if you use |latex| -and |dvips|, but \emph{not} when using |pdflatex|. This is true -both for the normal |graphics| package and for |pgf|. When using -|pgf|, do \emph{not} add the extension |.eps|. When using -|graphics|, do add the extension. - -If you have a |.eps| graphic and wish to use |pdflatex|, you can use -the program |ps2pdf| to convert the graphic to a |.pdf| file. Note, -however, that it is often a better idea to directly generate a |.pdf| -if the program that produced the |.eps| supports this. - - -\subsection{Including Graphic Files Ending \texttt{.pdf}, - \texttt{.jpg}, \texttt{.jpeg} or \texttt{.png}} - -The four formats |.pdf|, |.jpg|, |.jpeg|, and |.png| can only be -included by |pdflatex|. As before, do not add these extension when -using |pgf|, but do add them when using |graphics|. If your graphic -file has any of these formats and you wish/must you |latex| and -|dvips|, you have to convert your graphic to |.eps| first. - - -\subsection{Including Graphic Files Ending \texttt{.mps}} - -A graphic file ending |.mps| (MetaPost PostScript) is a special kind -of Encapsulated PostScript file. Files in this format are produced by -the MetaPost program. As you know, \TeX\ is a program that converts -simple plain text into beautifully typeset documents. The MetaPost -program is similar, only it converts simple plain text into beautiful -graphics. - -The MetaPost program converts a plain text file ending |.mp| -into an |.mps| file (although for some unfathomable reason the -extension is not added). The |.mp| file -must contain text written in the MetaFont programming language. Since -|.mps| files are actually also |.eps| files, you can use the normal -|\includegraphics| command to include them. - -However, as a special bonus, you can \emph{also} -include such a file when using |pdflatex|. Normally, |pdflatex| cannot -handle |.eps| files, but the |.mps| files produced by MetaPost have -such a simple and special structure that this is possible. The |graphics| -package implements some filters to convert such PostScript output to -\pdf\ on-the-fly. For this to work, the file should end |.mps| instead -of |.eps|. The following command can be used to make the |graphics| -package just \emph{assume} the extension |.mps| for any file it knows -nothing about (like files ending with |.1|, which is what MetaPost -loves to produce): -\begin{verbatim} -\DeclareGraphicsRule{*}{mps}{*}{} -\end{verbatim} - -This special feature currently only works with the |graphics| -package, not with |pgf|. - - - -\subsection{Including Graphic Files Ending \texttt{.mmp}} - -The format |.mmp| (Multi-MetaPost) is actually not format that can be -included directly in a \TeX-file. Rather, like a |.mp| file, it first -has to be converted using the MetaPost program. The crucial difference -between |.mp| and |.mmp| is that in the latter multiple graphics -can reside in a single |.mmp| file (actually, multiple graphics can -also reside in a |.mp| file, but by convention such a file is called -|.mmp|). When running MetaPost on a |.mmp| file, it will create not a -single encapsulated PostScript file, but several, ending |.0|, |.1|, -|.2|, and so on. The idea is that |.0| might contain a main graphics -and the following pictures contain overlay material that should be -incrementally added to this graphic. - -To include the series of resulting files, you can use the command -|\multiinclude| from the |mpmulti| or from the |xmpmulti| package. How -this program works is explained in Section~\ref{section-mpmulti}. - - - - - -%%% Local Variables: -%%% mode: latex -%%% TeX-master: "beameruserguide" -%%% End: |
