RectGraphicSimple

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

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.

The centre of this geometric / graphical element. The centre will not change if the object type is capable of being rotated and is rotated. The cenDefault on other bounded elements may move relative to points on the object when the object is rotated.

The default centre of this object is the centre. The centre will not change if the object type is capable of being rotated and is rotated.

The X component of the centre.

The Y component of the centre.

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.

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

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.

Rotate 180 degrees 2D geometric transformation on a ShapeGraphicSimple, returns a ShapeGraphicSimple. The return type will be narrowed in sub traits / classes.

Rotate 270 degrees anti clockwise or rotate 90 degrees clockwise 2D geometric transformation on a ShapeGraphicSimple, returns a ShapeGraphicSimple. The return type will be narrowed in sub traits / classes.

Rotate 90 degrees anti clockwise or rotate 270 degrees clockwise 2D geometric transformation on a ShapeGraphicSimple, returns a ShapeGraphicSimple. The return type will be narrowed in sub traits / 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.

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.
