Examples & Features
Supported Tile Sources
OpenSeadragon supports several image serving protocols out of
the box and is actively adding support for more. If the image
serving protocol you need is not supported, you can always
add support for yours using a custom tile source. (Please help
us add built-in support for your required image serving
protocol.) Each supported protocol aims to allow configuration
via XMLHTTPRequest, JSONP, as well as direct inline configuration.
Interface Elements and UI Customization
OpenSeadragon provides many optional interface elements which
can be easily enabled via simple configuration settings.
Additionally, OpenSeadragon aims to enable you to bind its
controls to entirely custom interfaces.
It's very common that sets of related images are required to be presented in a way that allows a user to easily navigate through them. OpenSeadragon provides simple options for this, as well as full multi-image support with complete control.
Advanced data model in OpenSeadragon with custom TileSource
From custom caching to client-side generated image data.

to add features to OpenSeadragon or when troubleshooting.
