|
||
|
|
*
|
||
|
|
* This file implements an XSLT transform to convert Content-MathML to
|
||
|
|
* Presentation MathML for processing by MathJax. The transform is
|
||
|
|
* performed in a pre-filter for the MathML input jax, so that the
|
||
|
|
* Show Math As menu will still show the Original MathML as Content MathML,
|
||
|
|
* but the Presentation MathML can be obtained from the main MathML menu.
|
||
|
|
*
|
||
|
|
* To load it, include
|
||
|
|
*
|
||
|
|
* MathML: {
|
||
|
|
* extensions: ["content-mathml.js"]
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* in your configuration.
