Debugger visualizers enable advanced, customized data display while you are running your application under the Visual Studio Debugger. Today's data windows have their limitations; they are text-only, hierarchical, and spatially constrained. They are not the best way to view an image, for example.
A visualizer is associated with a particular type. Whenever a variable of that type is included in a data window like the Watch window or DataTips, a little magnifying glass will be shown next to its entry. 
Version 220.127.116.11 Alpha comes with a debugger visualizer for Visual Studio 2005 / 2008 to help you quickly debug your Image Processing application. The visualizer can be used to inspect the following data types:
- Image<TColor, TDepth>
- Matrix<T> class
- DenseHistogram class
