Creating and Importing Tiled Images

Below you'll find step-by-step instructions for creating and importing tiled images into your Scalar project.

Tiled Images

Scalar supports the use of DZI files (.dzi), or Deep Zoom image files. The Deep Zoom file format functions in a manner similar to Google Maps images whereby large, high-resolution images are broken into smaller tiles which are then displayed individually only as needed, that is, only when that region of the overall image is being viewed.

Scalar users will need to create their DZI files using third party conversion tools (a list of converters can be found here). Because Deep Zoom images, and tiled images in general, require a number of associated files, Scalar users will need to find a place to host those files. Once the files have been hosted somewhere online, users can simply import the DZI file (.dzi) into their Scalar project using the internet URL importer.

See an example of a DZI file in Scalar.


DZI files are displayed in Scalar via OpenSeaDragon, an open-source, web-based viewer for zoomable images.
