JS9 brings our Desktop DS9 image display to your browser: - display FITS images and tables in a web page - display FITS data cubes and multi-extension files - drag and drop FITS images and tables - retrieve FITS files from data archives - change the colormap and scale - image pan, zoom and blink, table binning - image arithmetic, Gaussian smoothing - blend images and apply RGB image filters - configure mouse movements and touch events - create and manipulate regions of interest - extend JS9 using plugins and the public API - perform data analysis (local and server-side) - configure and control JS9 from within a web page - control JS9 from a command shell or Python - print images, save images, etc ... The JS9 Website contains on-line documentation, demos, and downloads: http://js9.si.edu Of course, JS9 also is available on GitHub: https://github.com/ericmandel/js9 JS9 is changing how we think about image display and analysis, moving beyond the Desktop into the Web. You can simply drag and drop a FITS image from your computer onto the JS9 display. All of basic JS9/DS9 functionality is immediately available: zoom, pan, colormaps, scaling, regions, WCS, etc. For full installation instructions, start with help/install.html. But really, just clone or download the JS9 source, display the js9.html page in your browser, and drag and drop a FITS file onto the JS9 display. You can extend JS9 using the Plugin facility in combination with the JS9 Public API. For example, you can perform browser-based analysis on the displayed image. On the JS9 Website, click the Plugins tab, create a region, and move it around ... In addition, URL-based data files support server-side analysis (using the original data files on the back-end server). Server-side analysis can be run, for example, in response to region changes, with the results displayed back in your browser. On the JS9 Website, click the Analysis tab, choose a task, create a region, and move it around ... We are very interested in exploring new uses for JS9 as we evolve its functionality in response to community needs. If you would like to join the fun, please contact us at: saord@cfa.harvard.edu.
