Version: 20160803
Prerequisites: pmwiki2.2.58
Status: Obsolete  use MathJax
Maintainer:
Ben Woodruff  You should consider using
MathJax instead. MathJax is the new jsMath.

Questions answered by this recipe
Notice that you can double click on images to see the LaTeX code.
 Can I get mathematical formulas to change size as the text changes size? (Yes. You can either install the TeX fonts, adjust the options in the jsMath control panel, or reload your page once you get to the desired size, and the images will download correctly.)
 Is there a way to print crisp clean mathematics directly from the webpage?
Description
Embed scalable mathematics in webpages with high print quality.
Notes
You can download jsMath from the author's website at http://www.math.union.edu/locate/jsMath. It is a javascript method of embedding mathematics into webpages. Users can either view mathematics output using precompiled images on the server, or users can download and install TeX fonts on their computer which speed up the view experience and increase the quality printing.
 Download jsMath.phpΔ and put it in the
cookbook/
directory
 Download and install the latest jsMath archive from Sourceforge into your PmWiki's
pub/
directory, as pub/jsMath/
. Or, you can install jsMath wherever you wish, and edit config.php
to set $JSMathUrl
to the url of the jsMath directory.
 Download and install the appropriate fonts from the author's website here
 Add the following line to a local customization file:
include_once('cookbook/jsMath.php');
That's it! The script adds {$$ ... $$} and {$...$} markups that
display LaTeXstyle math equations, the first form centers the
equation, while the second generates the equation "inline".
 You will find your experience to be better if you actually download
and install the jsMath fonts, but the site can be viewed just the
same without.
 The math graphic for the GUI toolbar is available at .
Using jsMath without ~80 MB of fonts
You can force jsMath to work without with font files. This only works if users are willing to download the font files to their computers. I modified the jsmath.php file as follows (not sure if some of this is redundant):
$HTMLHeaderFmt
['jsMath'] = '
<script> jsMath = {Controls: {cookie: {scale: 120}}} </script>
<script src="$JSMathUrl/plugins/noImageFonts.js"></script>
<script src="$JSMathUrl/plugins/autoload.js"></script>
';
$HTMLFooterFmt
['jsMath'] = '
<script src="$JSMathUrl/plugins/noImageFonts.js"></script>
<script>
jsMath.Autoload.Check();
jsMath.Process(document);
</script>
';

Comments
See Discussion at JsMathTalk
Disable message "No jsMath TeX fonts found"
I'm not sure what the newest developments of this recipe are, but I didn't care about font quality as long as one could read the formula on the screen. So I simply disabled the red message box above by adding the following line to config.php
before (!) the include_once
statement of this recipe (my reference):
$HTMLStylesFmt[] = "#jsMath_Warning {display: none}";
