Function

CGContextClosePath

Closes and terminates the current path’s subpath.

Declaration

void CGContextClosePath(CGContextRef c);

Parameters

c

A graphics context.

Discussion

Appends a line from the current point to the starting point of the current subpath and ends the subpath.

After closing the subpath, your application can begin a new subpath without first calling CGContextMoveToPoint. In this case, a new subpath is implicitly created with a starting and current point equal to the previous subpath’s starting point.

If the current path is empty or the current subpath is already closed, this function does nothing.
