AddPolyRulerAnnotInteractive Method (GdViewer)
In This Topic
Allows users to interactively add a new poly ruler 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.
A poly ruler annotation consists of several connected lines presenting its entire length. Users end every individual line with a single click, and they finish the annotation with a double-click.
The type of the newly added annotation object is GdPictureAnnotationType.AnnotationTypePolyRuler. You can change the annotation properties directly using the GdPicture14.Annotations.AnnotationPolyRuler 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.

Parameters
- BorderColor
- A color object that defines the required color of the newly added poly ruler annotation.
It is the color of the poly ruler's drawn lines and it corresponds to the AnnotationPolyRuler.StrokeColor property.
- BorderWidth
- The width of the newly added poly ruler annotation, in inches. It is the width of the poly ruler's drawn lines and it corresponds to the AnnotationPolyRuler.BorderWidth property.
- Opacity
- The opacity value of the newly added poly ruler annotation, from 0 (full transparency) to 1 (full opacity).
- MeasurementUnit
- The measurement unit of the newly added poly ruler.
The poly ruler presents its current length as the sum of the lengths of all connected lines in the defined unit at the end of the whole drawn line.
