TriangleFill

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.

Checks for 2 or more vertices

Checks for 3 or more vertices

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.

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.

Translate geometric transformation.

The number of vertices.
