addEllipse(in:transform:)
Adds an ellipse that fits inside the specified rectangle to the path.
Declaration
mutating func addEllipse(in rect: CGRect, transform: CGAffineTransform = .identity)Discussion
The ellipse is approximated by a sequence of Bézier curves. Its center is the midpoint of the rectangle defined by the rect parameter. If the rectangle is square, then the ellipse is circular with a radius equal to one-half the width (or height) of the rectangle. If the rect parameter specifies a rectangular shape, then the major and minor axes of the ellipse are defined by the width and height of the rectangle.
The ellipse forms a complete subpath of the path— that is, the ellipse drawing starts with a move-to operation and ends with a close-subpath operation, with all moves oriented in the clockwise direction.
Parameter:
rect: A rectangle that defines the area for the ellipse to fit in.
transform: An affine transform to apply to the ellipse before adding to the path. Defaults to the identity transform if not specified.
