images several bug fixes and enhancements. legacy tile source issue discovered and corrected for images with width greater than height. adding basic support for sequenced tile sources including previous and next buttons. added mouse drag and scroll interactions for viewport navigator. 2012-04-03 03:08:27 -04:00
licenses Adding ability to bind to buttons to custom interface elements, also use screen size detection to avoid using canvas on small devices since is more cpu intensive. Added version check for IE specific implementations to avoid using them for IE 9 and made most IE implementation differences a one-time process instead of an if/else which is evaulated on every call to the function. 2012-04-10 17:02:24 -04:00

OpenSeadragon

This project is a fork of the OpenSeadragon project at http://openseadragon.codeplex.com/

Building from Source

All command-line operations are scripted using Grunt which is based on Node.js. After installing Node, you will need to run this command once to install the required packages:

npm install

... then whenever you want to build, just run:

grunt

If you want Grunt to watch your source files and rebuild every time you change one, use:

grunt watch

The built files appear in the build folder.

Testing

Our tests are based on QUnit and PhantomJS; they're both installed when you run npm install. At the moment we don't have much in the way of tests, but we're working to fix that. To run on the command line:

grunt test

If you wish to work interactively with the tests or test your changes:

grunt server watch

and open http://localhost:8000/ in your browser
