Polyline

The returned pixel size of the graphics object generally applies applies to the outside border (bounding box). For polygons a higher value than the actually visible size is returned due to the presentation of the angles (PenJoin/PenCap). The returned value is typically 4 pixels bigger. A bigger value is also returned when the line width is set to 1 or the border is set to transparent.

The corner points of polygon sides can be "over" configured. This means that you can add a polygon side reference to a panel and change the size of the corner points.
