# `GSPath ellipseWithCenter:radius1:radius2:angle:`

*Initializer*

Creates a closed cubic path approximating an ellipse.

## Declaration

```swift
convenience init?(ellipseAt center: NSPoint, radius1 a: CGFloat, radius2 b: CGFloat, transform theta: CGFloat)
```

```objc
+ (instancetype) ellipseWithCenter:(NSPoint) center radius1:(CGFloat) a radius2:(CGFloat) b angle:(CGFloat) theta;
```

```python
ellipseWithCenter_radius1_radius2_angle_(center: NSPoint, a: float, b: float, theta: float) -> GSPath
```

## Discussion

The angle is measured in radians.

Returns `nil` when both radii are zero.
