Mirror, reflection transformation across the X axis. This method has been left abstract in GeomElemNew to allow the return type to be narrowed in sub classes.

Mirror, reflection transformation across the X axis. This method has been left abstract in GeomElemNew to allow the return type to be narrowed in sub classes.

2D geometric transformation using a ProlignMatrix on a GraphicElem, returns a GraphicElem. The Return type will be narrowed in sub traits / classes.

Reflect 2D geometric transformation across a line, line segment or ray on a GraphicElem, returns a GraphicElem. The Return type will be narrowed in sub traits / classes.

Rotation 2D geometric transformation on a GraphicElem taking the rotation as a scalar measured in radians, returns a GraphicElem. The Return type will be narrowed in sub traits / classes.

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

Uniform scaling transformation. The scale name was chosen for this operation as it is normally the desired operation and preserves Circles and Squares. Use the xyScale method for differential scaling.

XY scaling 2D geometric transformation on a GraphicElem, returns a GrpahicElem. This allows different scaling factors across X and Y dimensions. The return type will be narrowed in sub classes and traits.

Shear 2D geometric transformation along the X Axis on a GraphicElem, returns a GraphicElem. The return type will be narrowed in sub classes and traits.

Shear 2D geometric transformation along the Y Axis on a GraphicElem, returns a GraphicElem. The return type will be narrowed in sub classes and traits.

Translate geometric transformation.

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

Checks for 2 or more vertices

Checks for 3 or more vertices

The number of vertices.

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

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.

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