GraphicActive

The Pointer Identity is returned to the GUI application if the user mouse (or other pointing device, clicks within the polygon or shape It is purely up to the application to encode, its response if any to this object.

The definitive test as to whether the mouse pointer is inside the polygon / shape

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.

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

Mirror, reflection 2D geometric transformation across the X axis on a GraphicElem, returns a GraphicElem. The Return type will be narrowed in sub traits / classes.

Mirror, reflection 2D geometric transformation across the X axis on a GraphicElem, returns a GraphicElem. The Return type will be narrowed in sub traits / 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.

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.

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 2D geometric transformation on a GraphicElem, returns a GraphicElem. The Return type will be narrowed in sub traits / classes. 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 on the X and Y axes.

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