.NET Windows Forms in a Nutshell

Name

GraphicsPathIterator

Synopsis

This class is used to iterate the subpaths in a GraphicsPath object.

It can be constructed from a GraphicsPath object, and you can then step through the markers, subpaths, or connected line segments of the same type using the NextMarker(), NextSubpath(), and NextPathType() methods.

The Enumerate() function copies the path data into the specified arrays, and the CopyData() method allows you to copy just the path segments in a particular range (as retrieved from the enumeration methods mentioned above).
