[details](https://help.ctrader.com/ctrader-algo/references/Controls/Layout/Shapes/Polygon/Constructor/index.md) ## Properties - `public FillRule FillRule {get; set;}` — Gets or sets a FillRule enumeration that specifies how the interior fill of the shape is determined. [details](https://help.ctrader.com/ctrader-algo/references/Controls/Layout/Shapes/Polygon/FillRule/index.md) - `public Point[] Points {get; set;}` — Gets or sets a collection that contains the vertex points of the polygon.
