# CGPathAddRoundedRect

Appends a rounded rectangle to a mutable graphics path.

## Declaration

```occ
extern void CGPathAddRoundedRect(CGMutablePathRef path, const CGAffineTransform *transform, CGRect rect, CGFloat cornerWidth, CGFloat cornerHeight);
```

## Parameters

- `path`: The mutable path to change.
- `transform`: A pointer to an affine transformation matrix, or NULL if no transformation is needed. If specified, Core Graphics applies the transformation to the rectangle before adding it to the path.
- `rect`: The rectangle to add.
- `cornerWidth`: The width of the rounded corner sections.
- `cornerHeight`: The height of the rounded corner sections.

## Discussion

Discussion This is a convenience function that adds a path of an rounded rectangle. Each corner of the rounded rectangle is one-quarter of an ellipse with axes equal to the cornerWidth and cornerHeight parameters. The rounded rectangle forms a complete subpath and is oriented in the clockwise direction.
