AddRectangleHighlighterAnnotInteractive Method (GdViewer)

In This Topic
Allows users to interactively add a new rectangle highlighter annotation using the mouse on the current page of the document displayed in the GdViewer control. The annotation object is added following all the parameters you have specified and respecting the dimensions users will define using the mouse as well.

This annotation enables users to highlight a required area by adjusting the height and the width of the rectangle highlighter continuously using the mouse.

The type of the newly added annotation object is GdPictureAnnotationType.AnnotationTypeRectangleHighlighter. You can change the annotation properties directly using the GdPicture14.Annotations.AnnotationRectangleHighlighter class before or after the successful creation of the annotation object. Please refer to both the BeforeAnnotationAddedByUser and the AnnotationAddedByUser events for how to achieve this.

Be aware that the editing mode for annotations must be enabled using the SetAnnotationEditorMode method, otherwise this method will fail.
