It took them a long time, but the folks at MSDN finally got around to publishing the second part of my ColorPicker.NET article. In this one, I cover the implementation details for the scrolling magnifying glass control and the zoom panel that is used to magnify the captured portion of your desktop.

You can get the source code for v.0.2 from the ColorPicker.NET workspace. I haven't had the chance to recompile it in .NET v.2.0 yet, although I do have plans to continue developing the tool on that platform.
