So, the previous example of using the DeepZoom feature of Silverlight 2.0 wasn't exactly great and didn't show the potential of the function. But now.. here's a better example. First of all if you don't have Silverlight 2.0 installed yet.. go install it first cause Silverlight Streaming doesn't yet properly automated the Beta's installation.
The demo is here, it'll open up in a new window. Controls are still simple cause I have no time to change the previous code, so.. Click and Drag to move around the picture, Left Click to Zoom In, Shift + Left Click to Zoom Out.
