Bezier curves Kurven f\u00fcllen von Polygonen<\/p>\n
When I try this…<\/p>\n
[code lang=”delphi”]var
\np: array[0..20] of TPoint;
\nbegin
\ncanvas.MoveTo(50, 10);
\np[0].x := 10;
\np[0].y := 10;
\np[1].x := 50;
\np[1].y := 100;
\np[2].x := 10;
\np[2].y := 100;
\ncanvas.Brush.Style := bsSolid;
\ncanvas.brush.color := clBlack;
\ncanvas.PolyBezierTo(slice(p, 3));
\nend;
\n[\/code]<\/p>\n
it draws an bezier line (like method TCanvas.polyline), but i want a solid
\nobject (like TCanvas.polygon), without afterwards filling it. Is that
\npossible?
\n
\nWell, the code you posted doesn’t create a closed path, so I’m not
\nsure how you want it to be “filled.” In general, you can do this:<\/p>\n
1) Before drawing your curve:<\/p>\n
BeginPath(Canvas.Handle);<\/p>\n
2) After drawing your curve:<\/p>\n
CloseFigure(Canvas.Handle);
\nEndPath(Canvas.Handle);
\nStrokeAndFillPath(Canvas.Handle);<\/p>\n
