# addEllipse(in:transform:)

Adds an ellipse that fits inside the specified rectangle to the
path.

```
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.
