13  Including graphics

Beamer recognizes images in any of the pdf, png and jpg formats. (Note that PostScript is not among these.)

In the following sample we include three pictures side-by-side in a slide.

% graphics.tex 
\documentclass{beamer} 
\usetheme{Copenhagen} 
\begin{document} 
 
\begin{frame}{Graphics} 
 
Here we include three images, one each of PDF, PNG, and JPG types. 
 
\begin{center} 
  \includegraphics[width=0.3\textwidth]{image1.pdf} 
  \includegraphics[width=0.3\textwidth]{image2.png} 
  \includegraphics[width=0.3\textwidth]{image3.jpg} 
\end{center} 
 
\end{frame} 
 
\end{document} 

Here is the result:

Converting graphics

When you create an image with the intention of including it in a Beamer document, it is best if you save it in one of the pdf, png or jpg formats that are recognizable by Beamer.⁴ This is sometimes not possible. For instance, you may have downloaded the image from somewhere and it is in the gif format.

The department’s computer facilities provide a large number of utilities for converting and modifying graphical images.

eps to pdf

To convert an Encapsulated PostScript image to pdf, do:

epstopdf filename.eps 

This will produce a file named filename.pdf.⁵

All other conversions

The general-purpose convert⁶ command converts from any graphics format to any other graphics format. For instance, to convert a gif file to the png format, do:

convert filename.gif filename.png 

Similarly, to convert a tiff file to jpg, do:

convert filename.tiff filename.jpg 

In fact, we can have convert take over the job of epstopdf as well, as in:

convert filename.eps filename.pdf 

however in my experience epstopdf produces better results.
