Function

CGPathAddPath

Appends a path to onto a mutable graphics path.

Declaration

void CGPathAddPath(CGMutablePathRef path1, const CGAffineTransform *m, CGPathRef path2);

Parameters

path1

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 path2 before it is added to path1.

path2

The path to add.

Discussion

If the source path is non-empty, then its path elements are appended in order onto the mutable path. After the call completes, the start point and current point of the path are those of the last subpath in path2.
