Supported formats
Zoomable image viewers are built from a handful of underlying formats. Dezoomify understands the ones below, and picks the right one automatically from the address you give it, so you normally never need to choose. The list matters when automatic selection fails or when you want to check whether a site can be supported at all.
Most of these formats are named after the software that serves them. To use one by hand, paste the address of the page or of the small description file listed below; see finding the image address for how to find that file.
| Format | Used by | What you can paste |
|---|---|---|
| Zoomify | Many museums and libraries | The viewer page, ImageProperties.xml, or any tile address |
| Deep Zoom (Seadragon) | Microsoft-style viewers, many digital libraries | The viewer page or the .dzi file |
| IIIF | Widely used by national and university libraries | A viewer page, an info.json file, or a presentation manifest for whole books |
| Arts & Culture | Google Arts & Culture | The artwork page |
| IIPImage | Image servers recognizable by FIF= in addresses |
Any address containing FIF= |
| TopViewer (Memorix) | Dutch archive portals | The viewer page or a media metadata address |
| krpano | Panoramas and virtual tours | The viewer page or the tour's XML file |
| FSI Viewer | Neptune Labs image servers | The viewer page or the server metadata address |
| LizardTech ImageServer | ImageServer services | A calcrgn metadata address |
| Visual Library Server (VLS) | Semantics-based library portals | A zoom, pageview, or thumbview page |
| XLimage | Italian image servers | An .imgf or .imgi metadata address |
| Hungaricana | Hungarian Cultural Heritage Portal | A gallery page |
| ArcGIS MapServer | Cached map services | The MapServer address |
| WMTS | Geographic map tile services | The capabilities document address |
| pnav | Crop-based image services | An entity page |
| Generic | Any site whose tile addresses follow a simple pattern | A tile address with the two coordinates replaced by -- |
Generic
The generic format is the fallback when no named format matches. It needs
tile addresses that differ only by two numbers, the column and the row of
each piece. Paste one tile's address with both numbers replaced by --, as
described in finding the image address.
Is my site supported?
The fastest check is to try it. If it fails, the troubleshooting guide and finding the image address cover the common cases. Sites that need a brand-new recipe can be requested by opening an issue.
