We have released a beta of the VG.net vector graphics system containing fast scrolling enhancments. Click on the image above to run the Scrolling Scalability sample, to see the difference in performance. This demo is built with the 2.0 .net framework.
The new ScrollingMode property on Picture allows you to control the behavior. Using Accurate in the demo will show you the old performance. If you are a current VG.net 4.0/3.0 customer (full version), and your application should scroll faster, please email us for the beta download information, as well as the source code for the sample above. The source code contains a useful optimization technique for Pictures containing thousands of Elements, such as mapping applications.
