Parasol Framework Manual

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

CenterX DOUBLE 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.

CenterY DOUBLE 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.

Dimensions INT Dimension flags define whether individual dimension fields contain fixed or relative values.

The following dimension flags are supported:

Name	Description
FIXED_RADIUS_X	The RadiusX value is a fixed coordinate.
FIXED_RADIUS_Y	The RadiusY value is a fixed coordinate.
FIXED_CENTER_X	The CenterX value is a fixed coordinate.
FIXED_CENTER_Y	The CenterY value is a fixed coordinate.
SCALED_RADIUS_X	The RadiusX value is a scaled coordinate.
SCALED_RADIUS_Y	The RadiusY value is a scaled coordinate.
SCALED_CENTER_X	The CenterX value is a scaled coordinate.
SCALED_CENTER_Y	The CenterY value is a scaled coordinate.

Height DOUBLE The height (vertical diameter) of the ellipse.

The height of the ellipse is defined here as the equivalent of RadiusY * 2.0.

Radius DOUBLE 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 DOUBLE The horizontal radius of the ellipse.

The horizontal radius of the ellipse is defined here as either a fixed or scaled value.

RadiusY DOUBLE 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 DOUBLE The width (horizontal diameter) of the ellipse.

The width of the ellipse is defined here as the equivalent of RadiusX * 2.0.
