PolygonDrawImp

Renders this functional immutable GraphicElem, using the imperative methods of the abstract pCanv.CanvasPlatform interface.

The centre of the bounding rectangle. consider also using cenDefault.

The height of the BoundingRect of this object.

The bounding Rectangle provides an initial exclusion test as to whether the pointer is inside the polygon / shape

The width of the BoundingRect of this object.

If the geometric element has a defined centre then the cenDefault uses that, else it defaults to the centre of the bounding rectangle.

Checks for 2 or more vertices

Checks for 3 or more vertices

Mirror, reflection transformation across the X axis upon a PolygonDraw returns a PolygonDraw.

Mirror, reflection transformation across the X axis upon a PolygonDraw returns a PolygonDraw.

Mirror, reflection transformation across the X axis upon a PolygonDraw returns a PolygonDraw.

Mirror, reflection transformation across the X axis upon a PolygonDraw returns a PolygonDraw.

Mirror, rotate(radians) transformation across the X axis upon a PolygonDraw returns a PolygonDraw.

Rotation positive or anti-clockwise 180 degrees, 2D geometric transformation on a GraphicElem, returns a GraphicElem. The return type will be narrowed in subclasses and traits.

Rotation positive or anti-clockwise 270 degrees, 2D geometric transformation on a GraphicElem, returns a GraphicElem. The return type will be narrowed in subclasses and traits.

Rotation positive or anti-clockwise 90 degrees, 2D geometric transformation on a GraphicElem, returns a GraphicElem. The return type will be narrowed in subclasses and traits.

Uniform scaling transformation a PolygonDraw, returns a PolygonDraw.

Independent X and Y dimension scaling upon a PolygonDraw returns a PolygonDraw.

Shear along the X axis upon a PolygonDraw returns a PolygonDraw.

Shear along the Y axis upon a PolygonDraw returns a PolygonDraw.
