}
Build, and Run the program to test it.
Click the "Load From URL" button to load an image from a URL.
Click the "Load From Library" button to load an image from the Windows Phone photo library.
Click the various buttons to draw annotations.
NOTE: This tutorial demonstrates how to implement basic annotation features in LEADTOOLS. It does not include all annotation features. For a complete demo, see the "AutomationDemo" located in the LEADTOOLS 18\Examples\SilverlightPhone\CS directory.
