HOW TO: Keep track of regions you've created and select which ones to show

This C# 2005 demo uses the LEADTOOLS v15 .NET libraries to show how to:

1.
Add Rectangle, Ellipse, and Freehand regions with the RasterImageViewer's Interactive mode functionality
2.
Create your own data structure class and use the Windows System.Generic.Collections.LinkedList to keep track of the interactive regions you've added
3.
Use a CheckedListBox to select which regions you want to display.

The attached project has been updated to use the LEADTOOLS v17.5 in C# using Visual Studio 2008.

Note:
LEADTOOLS v15 did not contain the LeadRect or the LeadPoint data types, so the old implementation used Rectangle and RasterCollection of Point. But in LEADTOOLS v17.5, it is implemented using LeadRect and RasterCollection of LeadPoint. This project shows how to convert from Rectangle to LeadRect and from RasterCollection of Point to RasterCollection of LeadPoint.
