HOW TO: Restrict annotations to stay within image

Attached is a very simple Visual Studio 2015 WinForms project using LEADTOOLS 19 that illustrates how to set AnnAutomationManager.RestrictDesigners property to keep annotations within the area of the image in the viewer. In addition to setting this boolean property, you also need to set the container size using the AnnContainerMapper.SizeToContainerCoordinates() method.

Note: This will only work when an image is in the viewer, so a good practice is to put this code in the ItemChanged event of the viewer so that anytime an image is loaded, it will set the container size correctly.
