Nice post about Deep Zoom positioning

From the Silverlight SDK:

Although we’ve all got this worked out already, there’s some good illustrations, which always help to visualise how it works.

It’s a pity that they don’t go further into collection handling – that adds a further layer to the way the geometry is handled, as each subimage has its own ViewportWidth and ViewportOrigin and the way these interact with the parent image isn’t always obvious. I certainly had to work it all out by trial and error.
