Examples & Features

• Basics

  • Creating Zooming Images
  • Viewport Coordinates

• 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.

  • Legacy Image Pyramids
  • IIIF (International Image Interoperability Framework)
  • DZI (Deep Zoom Images)
  • OSM (Open Street Maps)
  • TMS (Tiled Map Service)
  • Zoomify
  • Custom Tile Sources
  • Simple Image

  In addition to the tile sources that are included in the core OpenSeadragon code, plugins are available that extend the default functionality. These may depend on external libraries, or can't be included in the main project for other reasons.

  • GeoTIFFTileSource - view TIFF-compatible files via geotiff.js

• 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.

  • Zoom and Pan
  • Overlays
  • Viewport Navigator
  • Rotation
  • Toolbar
  • Binding Custom Buttons
  • Keyboard Navigation
  • Customize Tooltips (I18n)
  • Crop TiledImage with Polygons

• Multi-Image Features

  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.

  • Sequence Mode
  • Image Reference Strip
  • Collection Mode
  • Full Multi-Image

• Advanced data model in OpenSeadragon with custom TileSource

  From custom caching to client-side generated image data.

  • Advanced data model with TileSource

• Developer Tools

  These settings can be useful for developers who are trying to add features to OpenSeadragon or when troubleshooting.

  • Debug Mode
