<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>
|

<p>
|

These features are generally controlled through various combinations of

the options: <ul>

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

ensure that you cannot pan the image far enough to fill the viewport with

<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.
|
||||
</p>
|
||||
|
||||
|
||||
|
||||
|
||||
<div class="description">
|
||||
<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.
