Polygon annotation with add/remove points

[Valentin Marteau]

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 ( https://www.pdftron.com/api/web/Annotations.PolygonAnnotation.html#getPath__anchor ).

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://www.pdftron.com/api/web/Annotations.PolygonAnnotation.html ).
