However, for practical -purposes for the rest of us, virtual fonts date from when Knuth -specified a format and wrote some support software, in 1989 (he -published an article in <i>TUGboat</i> at the time, and a plain text -copy is available on CTAN). -<p/>Virtual fonts provide a way of telling TeX about something more -complicated than just a one-to-one character mapping. The entities you -define in a virtual font look like characters to TeX (they appear -with their sizes in a TFM file), but the DVI processor may -expand them to something quite different. -<p/>From the virtual font file, the DVI processor learns -details of what is in the virtual font, so as to know “what to draw, -where”. The virtual font may contain commands: -<ul> -<li> just to remap the glyphs of a single font, -<li> to make a composite font with glyphs drawn from several - different fonts, or -<li> to build up an effect in arbitrarily complicated ways (since a - virtual font may contain anything which is legal in a DVI - file). -</ul> -<p/> - -In practice, the most common use of virtual fonts is to remap -Adobe Type 1 fonts (see <a href="FAQ-metrics.html">font metrics</a>), -though there has also been useful useful work building ‘fake’ maths -fonts (by bundling glyphs from several fonts into a single virtual -font). Virtual Computer Modern fonts, making a -<a href="FAQ-ECfonts.html">Cork encoded</a> font from Knuth’s originals by using -remapping and fragments of DVI for single-glyph ‘accented -characters’, were the first “Type 1 format” Cork-encoded Computer -Modern fonts available. -<p/>Virtual fonts are normally created in a single ASCII -VPL (Virtual Property List) file, which includes both sets of -information. The <i>vptovf</i> program is then used to the create -the binary TFM and VF files. -<p/>A “how-to” document, explaining how to generate a VPL, -describes the endless hours of fun that may be had, doing the job by -hand. Despite the pleasures to be had of the manual method, the -commonest way (nowadays) of generating VPL files is to use the -<i>fontinst</i> package, which is described in detail -together with the discussion of -<a href="FAQ-metrics.html">PostScript font metrics</a>. -<i>Qdtexvpl</i> is another utility for creating ad-hoc virtual -fonts (it uses TeX to parse a description of the virtual font, and -<i>qdtexvpl</i> itself processes the resulting DVI file). -<dl> -<dt><tt><i>fontinst</i></tt><dd><a href="http://mirror.ctan.org/fonts/utilities/fontinst.zip">fonts/utilities/fontinst</a> (or <a href="http://mirror.ctan.org/fonts/utilities/fontinst/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/fontinst.html">catalogue entry</a> -<dt><tt><i>Knuth on virtual fonts</i></tt><dd><a href="http://mirror.ctan.org/info/knuth/virtual-fonts">info/knuth/virtual-fonts</a>; <a href="http://mirror.ctan.org//help/Catalogue/entries/vf-knuth.html">catalogue entry</a> -<dt><tt><i>Virtual fonts “how to”</i></tt><dd><a href="http://mirror.ctan.org/info/virtualfontshowto/virtualfontshowto.txt">info/virtualfontshowto/virtualfontshowto.txt</a> -<dt><tt><i>qdtexvpl</i></tt><dd><a href="http://mirror.ctan.org/fonts/utilities/qdtexvpl.zip">fonts/utilities/qdtexvpl</a> (or <a href="http://mirror.ctan.org/fonts/utilities/qdtexvpl/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/qdtexvpl.html">catalogue entry</a> -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=virtualfonts">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=virtualfonts</a> -</body> |
