All code is licensed under the GPLv2. Javascript library for projecting lng/lat coordinates to x,y coordinates using the Robinson projection. See it in use on our Spin the Globe feature on the http://afar.com home page. Ported to Javascript by AFAR Media from ActionScript code written by Chris Youderian (http://www.flashmap.org/robinson-projection-in-as3-gpl/). --- Usage: myProjection = new Robinson(map_width, map_height); myProjection.project(lat, lng); // -> returns point object in the form {x:10, y:20} You can also use the projectToCSS() method in the same way to get a point which matches the CSS coordinate system.
