# scale(x:y:anchor:) Scales this shape without changing its bounding frame. ``` nonisolated func scale(x: CGFloat = 1, y: CGFloat = 1, anchor: UnitPoint = .center) -> ScaledShape ``` ## Parameters `x` The multiplication factor used to resize this shape along its x-axis. `y` The multiplication factor used to resize this shape along its y-axis. `anchor` The point to rotate the shape around. ## Return Value A scaled form of this shape. ## Discussion Both the `x` and `y` multiplication factors halve their respective dimension’s size when set to `0.5`, maintain their existing size when set to `1`, double their size when set to `2`, and so forth. --- Copyright © 2026 Apple Inc.
