Paper sizes can be a pain: +they’re a forgotten backwater — Knuth seems not to have considered +paper size as something the TeX engine needs to know about. As a +result, there is no DVI command to specify the paper on which +the document should be printed, which has led a dichotomy where macros +shape the text according to the needs of the author’s chosen paper +size, and device drivers’ choice happens independently of the macros’ +ideas. +<p/>In practice, one usually finds that macro packages (such as Plain TeX and +LaTeX) assume American “letter” paper size, by default; and since +most distributions nowadays originate in Europe, the drivers usually +default to ISO “A4” paper size. +<p/>This is (of course) pretty unsatisfactory. Users may select a +different paper size for their document (current LaTeX offers a +range of sizes as options in the standard classes), pretty easily. +Nevertheless, the user also has to be sure that each time +<i>xdvi</i>, <i>dvips</i> (or whatever) runs, it uses the +paper size the document was designed for. +<p/>The default paper size for DVI drivers may be changed by a +distribution management command (<i>texconfig</i> for TeX Live, +the <i>Options</i> application for MiKTeX), but this still +doesn’t provide for people using the “wrong” sort of paper for some +reason. +<p/>A different issue arises for users of PDFTeX — the +PDF format <em>does</em> have the means of expressing paper size +and PDFTeX has system variables <code>\</code><code>pdfpagewidth</code> and +<code>\</code><code>pdfpageheight</code>, that are written into the output PDF file. +Unfortunately, most of the core software predates PDFTeX, so not even +PDFLaTeX sets the correct values into those variables, to match the +paper size specified in a <code>\</code><code>documentclass</code> option. +<p/>The DVI drivers <i>dvips</i> and <i>dvipdfm</i> define +<code>\</code><code>special</code> commands for the document to specify its own paper size; +so in those cases, as when PDFTeX or VTeX is being used, the +paper size can be programmed by the document. Users who wish to, may +of course consult the manuals of the various programs to write the +necessary code. +<p/>The <i>geometry</i> package (whose main business is defining +typeset page areas), also takes notice the size of the paper that the +document is going to be printed on, and can issue the commands +necessary to ensure the correct size of paper is used. If +<i>geometry</i> is used when a document is being processed by +PDFLaTeX, it can set the necessary dimensions “in the output”. +If the document is being processed by LaTeX on a TeX or e-TeX +engine, there are package options which instruct <i>geometry</i> +which <code>\</code><code>special</code> commands to use. (Note that the options are +ignored if you are using either PDFLaTeX or VTeX.) +<p/>So, the resolution of the problem is to add +<blockquote> +<pre> +\usepackage[dvixxx,...]{geometry} +</pre> +</blockquote><p> +(where <code>dvixxx</code> is your current favourite DVI +driver — <i>geometry</i> knows about <code>dvips</code> and +<code>dvipdfm</code>), and the document will run correctly with +LaTeX. If you’re using PDFLaTeX, load with +<blockquote> +<pre> +\usepackage[pdftex,...]{geometry} +</pre> +</blockquote><p> +<p/>Needless to say, both the “big” classes (<i>koma-script</i> and +<i>memoir</i>) provide their own ways to get the paper size +“right”. +<p/>The <i>typearea</i> package is the <i>Koma-script</i> +distribution’s way of providing page layout functionality. Load it +with the <code>pagesize</code> option and it will ensure the correct +paper is selected, for PDF output from PDFLaTeX, and for +PostScript output from LaTeX via <i>dvips</i>. +<p/><i>Memoir</i> has the standard classes’ paper-size selections +(<code>a4paper</code>, <code>letterpaper</code> and so on), but also +permits the user to choose an arbitrary paper size, by setting the +length registers <code>\</code><code>stockheight</code> and <code>\</code><code>stockwidth</code>. The commands +<code>\</code><code>fixdvipslayout</code> (for LaTeX processing), and <code>\</code><code>fixpdflayout</code> +(for PDFLaTeX processing) then instruct the processor to produce +output that specifies the necessary paper size. +<dl> +<dt><tt><i>geometry.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/geometry.zip">macros/latex/contrib/geometry</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/geometry.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/geometry/">browse</a>) +<dt><tt><i>memoir.cls</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/memoir.zip">macros/latex/contrib/memoir</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/memoir.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/memoir/">browse</a>) +<dt><tt><i>typearea.sty</i></tt><dd>Distributed as part of <a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/koma-script.zip">macros/latex/contrib/koma-script</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/koma-script.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/koma-script/">browse</a>) +</dl> +<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=papergeom">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=papergeom</a> +</body> |
