He reasoned that this state could not persist for ever, -but that it would be foolish for him to define TeX primitives that -allowed the import of graphical image definitions. He therefore -deferred the specification of the use of graphics to the writers of -DVI drivers; TeX documents would control the drivers by -means of -<a href="FAQ-specials.html"><code>\</code><code>special</code> commands</a>. -<p/>There is therefore a straightforward way for anyone to import graphics -into their document: read the specification of the <code>\</code><code>special</code> -commands your driver uses, and ‘just’ code them. This is the -hair-shirt approach: it definitely works, but it’s not for everyone. -<p/>Over the years, therefore, “graphics inclusion” packages have sprung -up; most were designed for inclusion of - -<a href="FAQ-eps.html">Encapsulated PostScript graphics</a> — -which has become the <em>lingua franca</em> of graphics inclusion over -the last decade or so. -<p/>Notable examples are the <i>epsf</i> package (distributed with -<i>dvips</i>) and the <i>psfig</i> package. (Both of these -packages were designed to work well with both Plain TeX and -LaTeX 2.09; they are both still available.) All such packages were -tied to a particular DVI driver (<i>dvips</i>, in -the above two cases), but their code could be configured for others. -<p/>The obvious next step was to make the code configurable dynamically. -The LaTeX standard <i>graphics</i> package and its derivatives -made this step: it is strongly preferred for all current work. -<p/>Users of Plain TeX have two options allowing them to use -<i>graphicx</i>: the <i>miniltx</i> “LaTeX emulator” and -the <i>graphicx.tex</i> front-end allow you to load -<i>graphicx</i>, and <a href="FAQ-eplain.html">\Eplain</a> allows you to load -it (using the full LaTeX syntax) direct. -<p/>The <i>graphics</i> package takes a variety of “driver -options” — package options that select code to generate the -commands appropriate to the DVI driver in use. In most cases, -your (La)TeX distribution will provide a <i>graphics.cfg</i> file -that will select the correct driver for what you’re doing (for -example, a distribution that provides both LaTeX and PDFLaTeX -will usually provide a configuration file that determines whether -PDFLaTeX is running, and selects the definitions for it if so). -<p/>The <i>graphics</i> package provides a toolkit of commands (insert -graphics, scale a box, rotate a box), which may be composed to provide -most facilities you need; the basic command, <code>\</code><code>includegraphics</code>, -takes one optional argument, which specifies the bounding box of the -graphics to be included. -<p/>The <i>graphicx</i> package uses the facilities of of -<i>graphics</i> behind a rather more sophisticated command syntax -to provide a very powerful version of the <code>\</code><code>includegraphics</code> -command. <i>graphicx</i>’s version can combine scaling and -rotation, viewporting and clipping, and many other things. While this -is all a convenience (at some cost of syntax), it is also capable of -producing noticeably more efficient PostScript, and some of its -combinations are simply not possible with the <i>graphics</i> -package version. -<p/>The <i>epsfig</i> package provides the same facilities as -<i>graphicx</i>, but via a <code>\</code><code>psfig</code> command (also known as -<code>\</code><code>epsfig</code>), capable of emulating -the behaviour (if not the bugs) the old <i>psfig</i> package. -<i>Epsfig</i> also supplies homely support for former users of the -<i>epsf</i> package. However, there’s a support issue: if you -declare you’re using <i>epsfig</i>, any potential mailing list or -usenet helper has to clear out of the equation the possibility that -you’re using “old” <i>epsfig</i>, so that support is slower -coming than it would otherwise be. -<p/>There is no rational reason to stick with the old packages, which have -never been entirely satisfactory in the LaTeX context. (One -irrational reason to leave them behind is that their replacement’s -name tends not to imply that it’s exclusively related to PostScript -graphics. The reasoning also excludes <i>epsfig</i>, of course.) -<p/>A wide variety of detailed techniques and tricks have been developed -over the years, and Keith Reckdahl’s <i>epslatex</i> outlines them -in compendious detail: this highly recommendable document is available -from CTAN. An invaluable review of the practicalities of -exchanging graphics between sites, - -“<a href="http://silas.psfc.mit.edu/elec_fig/elec_figures.pdf">Graphics for Inclusion in Electronic Documents</a>” - -has been written by Ian Hutchinson; the document isn’t on CTAN, -but may also be - -<a href="http://silas.psfc.mit.edu/elec_fig/">browsed on the Web</a>. -<dl> -<dt><tt><i>epsf.tex</i></tt><dd><a href="http://mirror.ctan.org/macros/generic/epsf/epsf.tex">macros/generic/epsf/epsf.tex</a>; <a href="http://mirror.ctan.org//help/Catalogue/entries/epsf.html">catalogue entry</a> -<dt><tt><i>epsfig.sty</i></tt><dd>Part of the <a href="http://mirror.ctan.org/macros/latex/required/graphics.zip">macros/latex/required/graphics</a> (or <a href="http://mirror.ctan.org/macros/latex/required/graphics/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/graphics.html">catalogue entry</a> bundle -<dt><tt><i>epslatex.pdf</i></tt><dd><a href="http://mirror.ctan.org/info/epslatex.zip">info/epslatex</a> (or <a href="http://mirror.ctan.org/info/epslatex/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/epslatex.html">catalogue entry</a> -<dt><tt><i>graphics.sty</i></tt><dd><a href="http://mirror.ctan.org/macros/latex/required/graphics.zip">macros/latex/required/graphics</a> (or <a href="http://mirror.ctan.org/macros/latex/required/graphics/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/graphics.html">catalogue entry</a> -<dt><tt><i>graphicx.sty</i></tt><dd>Part of the <a href="http://mirror.ctan.org/macros/latex/required/graphics.zip">macros/latex/required/graphics</a> (or <a href="http://mirror.ctan.org/macros/latex/required/graphics/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/graphics.html">catalogue entry</a> bundle -<dt><tt><i>miniltx.tex</i></tt><dd><a href="http://mirror.ctan.org/macros/plain/graphics.zip">macros/plain/graphics</a> (or <a href="http://mirror.ctan.org/macros/plain/graphics/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/graphics-pln.html">catalogue entry</a> -<dt><tt><i>psfig.sty</i></tt><dd><a href="http://mirror.ctan.org/graphics/psfig.zip">graphics/psfig</a> (or <a href="http://mirror.ctan.org/graphics/psfig/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/psfig.html">catalogue entry</a> -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=impgraph">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=impgraph</a> -</body> |
