Requirements

Usage

bundle exec ./dzi-dl.rb 'http://example.com/dzi-viewer/viewer.ashx?zoom=image.xml'

To find a .dzi/.xml URL for a given Deep Zoom image viewer, you may need to open your web browser's Developer Tools and go to e.g. the "Network" pane, then reload the page and see what resources are loaded via AJAX.

Alternately, if you have PhantomJS installed, you can use dzixmlreqs.js to list all URLs ending in .dzi/.xml requested by a given webpage URL:

phantomjs dzixmlreqs.js 'http://example.com/viewer.asp?manuscript=shelfmark'

Docker Usage

There's also an automated build for this repository on Docker Hub at ryanfb/dzi-dl. It defines an ENTRYPOINT which will start dzi-dl.rb and pass any other arguments or environment variables to it, as well as defining a /data volume which you can map to your host to store manifests and images. For example, to download an image into the current directory:

docker run -t -v $(pwd):/data ryanfb/dzi-dl 'http://example.com/dzi-viewer/viewer.ashx?zoom=image.xml'
