Function

CGPathAddRect

Appends a rectangle to a mutable graphics path.

Declaration

void CGPathAddRect(CGMutablePathRef path, const CGAffineTransform *m, CGRect rect);

Parameters

path

The mutable path to change.

m

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.

Discussion

This is a convenience function that adds a rectangle to a path. Calling this function is equivalent to using CGRectGetMinX and related functions to find the corners of the rectangle, then using the CGPathMoveToPoint, CGPathAddLineToPoint, and CGPathCloseSubpath functions to add each line segment of the rectangle.
