* extensions/boldsymbol.js
|
|
*
|
|
* Part of the jsMath package for mathematics on the web.
|
|
*
|
|
* This file implements the \boldsymbol macro. You can activate it
|
|
* by calling
|
|
*
|
|
* jsMath.Extension.Macro('boldsymbol');
|
|
*
|
|
* which will cause the extension to be loaded only when it is
|
|
* needed, or you can force it to be loaded via
|
|
*
|
|
* jsMath.Extension.Require('boldsymbol');
|
|
*
|
|
* once jsMath.js has been loaded.
|
|
*
|
|
* Note that you will need to install the cmmib10 and cmbsy10 fonts
|
|
* that are available from the jsMath extra font page at
|
|
*
|
|
* http://www.math.union.edu/locate/jsMath/download/extra-fonts/
|
|
*
|
|
* to make this work in image mode. Note that there is no unicode
|
|
* fallback for these fonts at the moment.
