AnnTextPointerObject Class

Summary

This class provides support for creating and managing text pointer objects.

Remarks

The text pointer annotation object extends the AnnTextObject class by providing an extra line that starts from one of the four corners of the bounding rectangle, around the text. The other endpoint of the line can be moved to point to anything on the underlying image. This extra endpoint may or may not be fixed, depending on the IsFixedPointer value. For more information, refer to Using Text in WPF Annotation Objects. For more information about the text pointer annotation object refer to AnnTextPointerObject for WPF. For more information about the automated text pointer annotation object, refer to WPF Annotation Objects - Automated Features.

Example

For XAML example, refer to AnnGroupObject.

This example creates a new text pointer object.
