# contains(_:using:transform:)

Returns whether the specified point is interior to the path.

```
func contains(_ point: CGPoint, using rule: CGPathFillRule = .winding, transform: CGAffineTransform = .identity) -> Bool
```

## Parameters

`point`

The point to check.

`rule`

The rule for determining which areas to treat as the interior of the path. Defaults to the [`CGPathFillRule.winding`](/documentation/CoreGraphics/CGPathFillRule/winding) rule if not specified.

`transform`

An affine transform to apply to the point before checking for containment in the path. Defaults to the [`CGAffineTransformIdentity`](/documentation/CoreGraphics/CGAffineTransformIdentity) transform if not specified.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the point is interior to the path; otherwise, <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

A point is contained in a path if it would be inside the painted region when the path is filled.

## See Also

[`CGPathFillRule`](/documentation/CoreGraphics/CGPathFillRule)

Rules for determining which regions are interior to a path, used by the [`fillPath(using:)`](/documentation/CoreGraphics/CGContext/fillPath(using:)) and [`clip(using:)`](/documentation/CoreGraphics/CGContext/clip(using:)) methods.
