addRoundedRect(in:cornerRadii:style:transform:)

Declaration

mutating func addRoundedRect(in rect: CGRect, cornerRadii: RectangleCornerRadii, style: RoundedCornerStyle = .continuous, transform: CGAffineTransform = .identity)

Parameters

• rect:

  A rectangle, specified in user space coordinates.

• cornerRadii:

  The radius of each corner of the rectangle, specified in user space coordinates.

• style:

  The corner style. Defaults to the continous style if not specified.

• transform:

  An affine transform to apply to the rectangle before adding to the path. Defaults to the identity transform if not specified.

Discussion

This is a convenience function that adds a rounded rectangle to a path, starting by moving to the center of the right edge and then adding lines and curves counter-clockwise to create a rounded rectangle, closing the subpath.
