Function

CGPathAddRoundedRect

Appends a rounded rectangle to a mutable graphics path.

Declaration

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

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.
