# addEllipse(in:)

Adds an ellipse that fits inside the specified rectangle.

## Declaration

```swift
func addEllipse(in rect: CGRect)
```

## Parameters

- `rect`: A rectangle that defines the area for the ellipse to fit in.

## Discussion

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.
