Most often, the requirement is for -something that can be included in HTML generated from (La)TeX -source — not everything that you can write in (La)TeX can be -translated to HTML (at least, portable HTML that may be -viewed in ‘most’ browsers), so the commonest avoiding action is to -generate a bitmap of the missing bit. Examples are maths (a maths -extension to the ‘<code>*</code>ML’ family is available but not -universally supported by browsers), and ‘exotic’ typescripts (ones -that you cannot guarantee your readers will have available). Other -common examples are generation of -sample bitmaps, and generation for insertion into some other -application’s display — to insert equations into Microsoft -PowerPoint, or to support the enhanced-<i>emacs</i> setup called -<a href="FAQ-WYGexpts.html"><i>preview</i>-<i>latex</i></a>. -<p/>In the past, the commonest way of generating bitmaps was to generate a -PostScript file of the DVI and then use <i>ghostscript</i> to -produce the required bitmap format (possibly by way of PNM -format or something similar). This is an undesirable procedure (it is -very slow, and requires two or three steps) but it has served for a -long time. -<p/>(La)TeX users may now take advantage of two bitmap ‘drivers’. The -longer-established, <i>dvi2bitmap</i>, will generate XBM and -XPM formats, the long-deprecated GIF format (which is -now obsolescent, but has finally been relieved of the patent -protection of the LZW compression it uses), and also -the modern (ISO-standardised) PNG format. -<p/>Dvipng started out as a PNG renderer; from version 1.2 it can also -render to the GIF format. It is designed for speed, in environments that -generate large numbers of PNG files: the <i>README</i> mentions -<i>preview</i>-<i>latex</i>, <i>LyX</i>, and a few -web-oriented environments. Note that <i>dvipng</i> gives -high-quality output even though its internal operations are optimised -for speed. -<dl> -<dt><tt><i>dvi2bitmap</i></tt><dd><a href="http://mirror.ctan.org/dviware/dvi2bitmap.zip">dviware/dvi2bitmap</a> (or <a href="http://mirror.ctan.org/dviware/dvi2bitmap/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/dvi2bitmap.html">catalogue entry</a> -<dt><tt><i>dvipng</i></tt><dd><a href="http://mirror.ctan.org/dviware/dvipng.zip">dviware/dvipng</a> (or <a href="http://mirror.ctan.org/dviware/dvipng/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/dvipng.html">catalogue entry</a> -</dl> -<p/> -<p/><p/><p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=dvi-bmp">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=dvi-bmp</a> -</body> |
