DescriptionDiva.js is an open-source document image viewer, especially suited for use in archival book digitization initiatives where viewing high-resolution images is a crucial part of the user experience. Using Diva, libraries, archives, and museums can present high-resolution document page images in a user-friendly “instant-on” interface that has been optimized for speed and flexibility.
Version 6.0 contains many new features and improvements:
- Compatibility with IIIF Presentation API version 2.1 and 3.
- Small footprint, zero dependencies. Can be deployed with just a JavaScript and a CSS file.
- Rewritten in ES6 for compatibility with the new JavaScript module system.
- New plugins: Metadata, Image Manipulation
To browse through the pages within a document, simply scroll through the document panel using the scroll wheel, the scrollbar or the arrow keys. To zoom in, either click the plus button or double-click the page you are viewing. To zoom out, click the minus button or hold control while double-clicking the current page. Note that on a touch screen, the usual touch gestures will work to zoom-in, zoom-out and scroll. Change views and enter fullscreen mode by clicking the icons above the viewer pane on the upper right.
There are two main components to a Diva.js install:
- A IIIF-compatible image server to host the IIIF manifests to be displayed.
- The Diva.js viewer itself. Diva is embedded in your web page and displays the images.
