The MathZoom extension

**********************
|
|
|
|
The options below control the operation of the Math-Zoom feature that
|
|
allows users to see an enlarged version of the mathematics when they
|
|
click or hover over typeset mathematics. They are listed with their
|
|
default values. To set any of these options, include a ``MathZoom``
|
|
section in your :meth:`MathJax.Hub.Config()` call. For example
|
|
|
|
.. code-block:: javascript
|
|
|
|
MathJax.Hub.Config({
|
|
MathZoom: {
|
|
delay: 600
|
|
}
|
|
});
|
|
|
|
would set the ``delay`` option to 600 milliseconds.
|
|
|
|
Mathematics is zoomed when the user "triggers" the zoom by an action,
|
|
either clicking on the mathematics, double-clicking on it, or holding
|
|
the mouse still over it (i.e., "hovering"). Which trigger is used is
|
|
set by the user via the math contextual menu (or by the author using
|
|
the ``menuSettings`` configuration section).
|
|
|
|
.. describe:: delay: 400
|
|
|
|
This the time (in milliseconds) that the mouse must be still over a
|
|
typeset mathematical formula before the zoomed version is displayed
|
|
(when the zoom trigger is set to `Hover`).
|
|
|
|
.. describe:: styles: {}

|
This is a list of CSS declarations for styling the zoomed
|
|
mathematics. See the definitions in ``extensions/MathZoom.js``
|
|
for details of what are defined by default. See :ref:`CSS Style
|
|
Objects <css-style-objects>` for details on how to specify CSS
|
|
style in a JavaScript object.
