<h2>example: zoom and pan options</h2>
|

<p>

A deep zoom viewport allows several options to be set in order to constrain

the minimum and maximum zoom range as well as the range of panning.

</p>
|

|
<strong>panHorizontal</strong><em>(default:) true</em>

<h2>

example: deep zoom image support
|

|
</h2>
|
||||||
|
<p>
|
||||||
|
The DZI (Deep Zoom Image) format is an
|
||||||
|
xml specification maintained by Microsoft and described <a
|
||||||
|
href='http://msdn.microsoft.com/en-us/library/cc645077(v=vs.95).aspx'>here</a>.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
OpenSeadragon has added supports for DZI format via AJAX ( XML/JSON ), JSONP,
|
||||||
|
and as inline configuration ( using the json format ). The DZI specification
|
||||||
|
does not officially describe a JSON format however the
|
||||||
|
examples below illustrate how DZI xml is mapped to json following some
|
||||||
|
simple conventions.

<h3>Inline Configuration for DZI</h3>
|
||||||
|
<p>
|
||||||
|
Inline configuration is convenient as well because it avoids a potentially
|
||||||
|
complicated JSON/XML Ajax request over the network. Just plop the equivalent
|
||||||
|
json directly into 'tileSources' option.

Configuration is done via the 'tileSources' option ( or programatically ).
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Note however the non-standard dzi property 'Url' which we must supply
|
||||||
|
explicitly since this is normally inferred by the path specified
|
||||||
|
for the dzi XML/JSON/JSONP.
