Polygon annotation with add/remove points

Hello,

Is there a possibility to add / remove points once a polygon annotation has been drawn?

Thanks and best regards,
Valentin

Hi Valentin,

You can use the “getPath” API on the annotation to get the array of points ( Apryse WebViewer Class: IPathAnnotation).
If you modify the array ( push, slice, etc), it will affect the annotation.

Alternatively, you can also use the “addPoint” , “popPath”, and “setPathPoint” to manipulate the path https://docs.apryse.com/api/web/Core.Annotations.PolygonAnnotation.html#main.
