Using Imported Graphics in L A T E X2 ε Keith Reckdahl [email protected] Version 2.0 December 15, 1997 Summary This document explains how to use imported graphics in L A T E X 2 ε documents. While reading the entire document is certainly worthwhile, most users should be able to locate the necessary information by browsing the table of contents on pages 3-5 or the index on pages 84-86. While L A T E X can import virtually any graphics format, Encapsulated PostScript ( eps ) is the easiest graphics format to import into L A T E X. For example, eps files are inserted by specifying \usepackage{graphicx} in the document’s preamble and then using the command \includegraphics{file.eps} Optionally, the graphic can be scaled to a specified height or width \includegraphics[height=4cm]{file.eps} \includegraphics[width=3in]{file.eps} Additionally, the angle option rotates the included graphic \includegraphics[angle=45]{file.eps} The \includegraphics command and the rest of the L A T E X 2 ε graphics bundle are covered in Part II of this document. This document is divided into the following four parts Part I: Background Information This part provides historical information and describes basic L A T E X terminol- ogy. It also describes the Encapsulated PostScript ( eps ) format, differences between eps and ps files, and methods for converting non- eps graphics to eps . Part II: The L A T E X Graphics Bundle This part describes the commands in the graphics bundle which import, scale, and rotate graphics. This part covers much of the information in the graphics bundle documentation (reference [5]). Part III: Using Graphics Inclusion Commands This part describes how the graphics bundle commands are used to import, rotate, and scale graphics. Three situations where graphics inclusion is mod- ified are also covered: Compressed eps files and non- eps graphic formats ( tiff , gif , jpeg , pict , etc.) can also be inserted on-the-fly when dvips is used with an operating system which supports pipes (such as Unix). When using other operating systems, the non- eps graphics must be converted to eps beforehand. Since neither L A T E X nor dvips has any built-in decompression or graphics- conversion capabilities, that software must be provided by the user. c Copyright 1995-97 by Keith Reckdahl.

Since many graphics applications support only ascii text, the ps frag system allows text in eps files to be replaced with L A T E X symbols or mathematical expressions. When an eps graphic is inserted multiple times (such as a logo behind the text or in the page header) the final PostScript includes multiple copies of the graphics. When the graphics are not bitmapped, a smaller final PostScript file can be obtained by defining a PostScript command for the graphics.
