Summary
Adds a Bézier spline to the current figure of this path.
Description
Call this method to add a Bézier spline to the current figure of this path.
Example:
The following example creates a TGPGraphicsPath object path, adds a Bézier spline to path, closes the current figure (the only figure in this case), and then draws path.
var AGraphics : IGPGraphics; APath : IGPGraphicsPath; begin AGraphics := TGPGraphics.Create( ACanvas ); APath := TGLPath.Create(); APath.AddBezier( MakePoint(50, 50), MakePoint(60, 20), MakePoint(70, 100), MakePoint(80, 50)); APath.CloseFigure(); // Draw the path. graphics.DrawPath( TGPPen.Create( aclRed ), APath ); end;
