Deep Zoom Picture of Grant's Web Data

This project is woefully out of date and the Silverlight version it was developed for is no longer supported. Don't expect the below to work as-is.

For the past two days I've been playing with Microsoft's Silverlight. It's a really cool technology. I'm most impressed with their Deep Zoom development. I decided I wanted to be able to automatically generate Deep Zoom images without using the Deep Zoom Composer. I've created a tool which:

• Reads a text file.
• Generates images representing the text.
• Uses SparseImageTool.exe in the Deep Zoom Composer package to create the Deep Zoom image.

By combining the generated files with a Silverlight application developed in Visual Studio 2008, I was able to generate this. The pictured text is all the data files that are viewable to any user in the wiki system for this website.
