Syntax
Delphi:
function NextSubpath( startIndex : Integer, endIndex : Integer, isClosed : bool ) : Integer;
C++ Builder:
int __fastcall NextSubpath( int startIndex, int endIndex, bool isClosed );
Visual C++ (MFC):
NextSubpath( startIndex, endIndex, isClosed );
Summary
Returns the starting index and the ending index of the next subpath (figure) in the iterator's associated path.
Description
Call this method to get the starting index and the ending index of the next subpath (figure) in the iterator's associated path. Remarks The first time you call the NextSubpath method of an iterator, it gets the indices for the first figure (subpath) of that iterator's associated path. The second time, it gets the indices for the second figure, and so on. Each time you call NextSubpath, it returns the number of data points in the figure whose indices were retrieved. When there are no figures remaining, it returns 0.
