Drawing Cross Browser Vector Graphics

Our new Drawing Module was created to answer a simple question:

How do I draw in the browser?

If you’ve ever wanted to draw and modify non-rectilinear, browser-native shapes in your web applications, then our new Drawing Module was designed with you in mind. Create, manipulate, and edit arbitrary shapes and styles within your applications without the hassle of cross-browser incompatibility. The Drawing Module allows easy creation of interactive diagrams, flowcharts, custom charts or other data visualizations and interfaces.  This new cross-browser vector graphics package and more are coming soon in Smart GWT 3.0 and SmartClient 8.2.

Works everywhere. No plug-ins required.

We’ve used native browser drawing capabilities to provide a consistent interface requiring no plug-ins or third party software when using commonly used browsers. As with our HTML5 charting feature, the Drawing module utilizes Scalable Vector Graphics (SVG) or <canvas> in modern browsers, and Vector Markup Language (VML) in Internet Explorer 6-8 to ensure cross-platform compatibility.  In addition, the Drawing Module works in mobile WebKit for integrated mobile device support (iOS and Android). The result is a flexible vector graphics library that works everywhere you need it.
