Visual C++ (MFC):
Reverse();
Summary
Reverses the order of the points that define this path's lines and curves.
Description
Call this method to reverse the order of the points that
define this path's lines and curves. Example: The following example creates a TGPGraphicsPath object path, adds two lines to path, calls the Reverse method, and then draws path.
var AGraphics : IGPGraphics; APath : IGPGraphicsPath; begin AGraphics := TGPGraphics.Create( ACanvas ); APath := TGLPath.Create(); // Set up and call Reverse.
APath.AddLines( [ MakePoint(10, 60), MakePoint(50, 110), MakePoint(90, 60) ] );
APath.Reverse();
// Draw the path.
AGraphics.DrawPath( TGPPen( aclRed ), APath );
end;
Remarks A TGPGraphicsPath object has an array of points and an array of types. Each element in the array of types is a byte that specifies the point type and a set of flags for the corresponding element in the array of points. Possible point types and flags are listed in the TGPPathPointType enumeration.
This method reverses the order of the elements in the array of points and in the array of types.
