[](https://gitter.im/openseadragon/openseadragon?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
|
|
|
|
An open-source, web-based viewer for zoomable images, implemented in pure JavaScript.
|
|
|
|
See it in action and get started using it at http://openseadragon.github.io/.
|
|
|
|
## Stable Builds
|
|
|
|
See the [GitHub releases page](https://github.com/openseadragon/openseadragon/releases).
|
|
|
|
## Development
|
|
|
|
If you want to use OpenSeadragon in your own projects, you can find the latest stable build, API documentation, and example code at http://openseadragon.github.io/. If you want to modify OpenSeadragon and/or contribute to its development, read on.
|
|
|
|
### First Time Setup
|
|
|
|
All command-line operations for building and testing OpenSeadragon are scripted using [Grunt](http://gruntjs.com/) which is based on [Node.js](http://nodejs.org/). To get set up:
|
|
|
|
1. Install Node, if you haven't already (available at the link above)
|
|
1. Install the Grunt command line runner (if you haven't already); on the command line, run `npm install -g grunt-cli`
|
|
1. Clone the openseadragon repository
|
|
1. On the command line, go in to the openseadragon folder
|
|
1. Run `npm install`
|
|
|
|
You're set... continue reading for build and test instructions.
|
|
|
|
### Building from Source
|
|
|
|
To build, just run (on the command line, in the openseadragon folder):
|
|
|
|
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.
|
|
|
|
If you want to build tar and zip files for distribution (they will also appear in the `build` folder), use:
|
|
|
|
grunt package
|
|
|
|
Note that the `build` folder is masked with .gitignore; it's just for your local use, and won't be checked in to the repository.
|
|
|
|
You can also publish the built version to the site-build repository. This assumes you have cloned it next to this repository. The command is:
|
|
|
|
grunt publish
|
|
|
|
... which will delete the existing openseadragon folder, along with the .zip and .tar.gz files, out of the site-build folder and replace them with newly built ones from the source in this repository; you'll then need to commit the changes to site-build.
|
|
|
|
### Testing
|
|
|
|
Our tests are based on [QUnit](http://qunitjs.com/) and [PhantomJS](http://phantomjs.org/); 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 connect watch
|
|
|
|
and open `http://localhost:8000/test/test.html` in your browser.
|
|
|
|
Another good page, if you want to interactively test out your changes, is `http://localhost:8000/test/demo/basic.html`.
|
|
|
|
You can also get a report of the tests' code coverage:
|
|
|
|
grunt coverage
|
|
|
|
The report shows up at `coverage/html/index.html` viewable in a browser.
|
|
|
|
### Contributing
