Description

Call this method to start a new figure without closing the

current figure. Subsequent points added to this path are
added to the new figure.



Example:

The following example creates a path and adds two figures to
that path. The first figure has three arcs, and the second
figure has two arcs. The arcs within a figure are connected
by straight lines, but there is no connecting line between
the last arc in the first figure and the first arc in the
second figure.

var
  AGraphics : IGPGraphics;
  APath : IGPGraphicsPath;

begin
  AGraphics := TGPGraphics.Create( ACanvas );
  APath := TGLPath.Create();

  APath.AddArc(0, 0, 100, 50, 0.0, 180.0);
  APath.AddArc(0, 60, 100, 50, 0.0, 180.0);
  APath.AddArc(0, 120, 100, 50, 0.0, 180.0);

  // Start a new figure (subpath).
  // Do not close the current figure.
  APath.StartFigure();
  APath.AddArc(0, 180, 100, 50, 0.0, 180.0);
  APath.AddArc(0, 240, 100, 50, 0.0, 180.0);

  AGraphics.DrawPath( TGPPen( aclRed ), APath );
end;
