Obama to JFK Deep ZoomAll Silverlight Examples, Deep Zoom, Silverlight 3 tutorials, Silverlight Effects, by Gavin Wignall.
Click or use the mouse wheel to zoom into the picture frames to take a journey through the last 10 Presidents of the United States.
This example was put together with Deep Zoom Composer.
I hit a problem with hitting over 4 billion pixels in Deep Zoom Composer, to avoid this I found I could only go 6 pictures in depth.
To get the full 10 pictures working I used the following work around. First off the application won’t let you export a project when you hit over 4 billion pixels, but it will let you run a preview. By running a preview the program will create a .xap file and a Generate Images folder. The preview will open up, but the files it creates don’t seem to work once accessing them after the preview is closed. By changing the .xap to a .zip you can access the contents inside, of which one file is the .xaml file. I copied this across into the exported project (the one containing 6 images deep) and then changed the file extension back to .xap. Then I copied across the Generated Images folder and hey presto I got 10 working. I couldn’t get any more than 10 working, I would have loved to of gone through all 44 Presidents.
