<h2>
|

example: iiif tiles support
|
||||
</h2>
|
||||
<p>
|
||||
The International Image Interoperability Format is described formally here
|
||||
<a href='http://library.stanford.edu/iiif/image-api/'
|
||||
>http://library.stanford.edu/iiif/image-api/</a>.
|
||||
</p>
|
||||
<p>
|
||||
The IIIF API specifies a web service that returns an image in response to a standard http or https request.
|
||||
The URL can specify the region, size, rotation, quality characteristics and format of the requested image. A
|
||||
URL can also be constructed to request basic technical information about the image to support client
|
||||
applications. The IIIF API was conceived of to facilitate systematic reuse of image resources in digital
|
||||
image repositories maintained by cultural heritage organizations. The API could be adopted by any image
|
||||
repository or service, and can be used to retrieve static images in response to a properly constructed URL.
|
||||
</p>
|
||||
<p>
|
||||
OpenSeadragon has added support for IIIF thanks to several of its specifications authors
|
||||
as well as the gist provided by <a href='http://github.com/jstroop'>Jon Stroop</a> at
|
||||
<a href='https://gist.github.com/jpstroop/4624253'>this gist</a>.

<h3>Inline Configuration for IIIF tile sources.</h3>
|
||||
<p>
|
||||
Inline configuration is very straight forward. The tile source type is
|
||||
identified by it's <strong>profile</strong> attribute an must specify the
|
||||
url of the tile service with the <strong>tilesUrl</strong> attribute.
