# 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.

```
enum CGPathFillRule
```

## Overview

When filling a path, regions that a fill rule defines as interior to the path are painted. When clipping with a path, regions interior to the path remain visible after clipping.

## Topics

### Enumeration Cases

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

A rule that considers a region to be interior to a path based on the number of times it is enclosed by path elements.

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

A rule that considers a region to be interior to a path if the winding number for that region is nonzero.
