Extends the Vector class with support for elliptical path generation.

The VectorEllipse class provides the necessary functionality for elliptical path generation.

Structure

The VectorEllipse class consists of the following fields:

Access	Name	Type	Comment
	CX	UNIT	The horizontal center of the ellipse. Expressed as a fixed or scaled coordinate.
The horizontal center of the ellipse is defined here as either a fixed or scaled value.
	CY	UNIT	The vertical center of the ellipse. Expressed as a fixed or scaled coordinate.
The vertical center of the ellipse is defined here as either a fixed or scaled value.
	Height	UNIT	The height (vertical diameter) of the ellipse.
The height of the ellipse is defined here as the equivalent of `RadiusY * 2.0`.
	Radius	UNIT	The radius of the ellipse. Expressed as a fixed or scaled coordinate.
The radius of the ellipse is defined here as either a fixed or scaled value. Updating the radius will set both the RadiusX and RadiusY values simultaneously.
	RadiusX	UNIT	The horizontal radius of the ellipse.
The horizontal radius of the ellipse is defined here as either a fixed or scaled value.
	RadiusY	UNIT	The vertical radius of the ellipse.
The vertical radius of the ellipse is defined here as either a fixed or scaled value.
	Vertices	INT	Limits the total number of vertices generated for the ellipse.
Setting a value in Vertices will limit the total number of vertices that are generated for the ellipse. This feature is useful for generating common convex geometrical shapes such as triangles, polygons, hexagons and so forth; because their vertices will always touch the sides of an elliptical area. Please note that this feature is not part of the SVG standard.
	Width	UNIT	The width (horizontal diameter) of the ellipse.
The width of the ellipse is defined here as the equivalent of `RadiusX * 2.0`.

Actions

The following actions are currently supported:

Move

Moves the center of the ellipse by a relative distance.

ERR acMove(*Object, DOUBLE DeltaX, DOUBLE DeltaY, DOUBLE DeltaZ)

Parameter	Description
DeltaX	The number of units to move along the X axis.
DeltaY	The number of units to move along the Y axis.
DeltaZ	The number of units to move along the Z axis.

MoveToPoint

Moves the center of the ellipse to a new position.

ERR acMoveToPoint(*Object, DOUBLE X, DOUBLE Y, DOUBLE Z, MTF Flags)

Parameter	Description
X	The new X position to move the object to.
Y	The new Y position to move the object to.
Z	The new Z position to move the object to.
Flags	Set the relevant MTF flag for each provided parameter.
