CircleGraphicSimple

The most narrow type preserved in some 2d geometric transformations.

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.

Mirror, reflection 2D geometric transformation across the Y axis by negating X. The return type will be narrowed in sub traits / classes.

Mirror, reflection 2D geometric transformation across the X axis by negating y. The return type will be narrowed in sub traits / classes.

2D Transformation using a ProlignMatrix. The return type will be narrowed in sub classes / traits.

A method to perform all the ProlignPreserve transformations with a function from PT2 => PT2.

Reflect 2D geometric transformation across a line, line segment or ray on a GeomElem. The return type will be narrowed in sub classes and traits.

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

Rotation 2D geometric transformation on a GeomElem. The return type will be narrowed in sub classes and traits.

Rotation of 180 degrees, 2D geometric transformation on a GeomElem, returns a GeomElem. The return type will be narrowed in sub classes and traits.

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

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

Uniform 2D geometric 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. The Return type will be narrowed in sub traits / classes.

Scaling X and Y axes independently, 2D geometric transformation on this GeomElem, returns a new GeomElem. This allows different scaling factors across X and Y dimensions. The return type will be narrowed in sub classes and traits. This is an affine transformation but it is not a similar transformation.

Shear 2D geometric transformation along the X Axis on a GeomElem. The return type will be narrowed in sub classes and traits. This is an affine transformation but it is not a similar transformation.

Shear 2D geometric transformation along the Y Axis on a GeomElem. The return type will be narrowed in sub classes and traits. This is an affine transformation but it is not a similar transformation.

Translate 2D geometric transformation, taking the xOffset and yOffset as parameters on this GeomElem returning a GeomElem. The Return type will be narrowed in sub traits. End users will often want to use the slate method taking a Pt2 or Vec2 as a parameter, the slateX or the slateY methods. These methods will be offered as extension methods using this method for their implementations.
