WinAPI: Polyline - 绘制一组连续线段

//声明:
Polyline(
  DC: HDC;       {设备环境句柄}
  var Points;    {点数组}
  Count: Integer {数组元素个数}
): BOOL;

{Polyline 与 Polygon 的参数一模一样, 但 Polygon 能自动闭合}

 
 
 
 
 

 

 
  

//绘制连续直线 Polyline
procedure TForm1.FormPaint(Sender: TObject);
var
  ps: array[0..5] of TPoint;
begin
  ps[0].X := 50;
  ps[0].Y := 50;
  ps[1].X := 100;
  ps[1].Y := 50;
  ps[2].X := 125;
  ps[2].Y := 75;
  ps[3].X := 100;
  ps[3].Y := 100;
  ps[4].X := 50;
  ps[4].Y := 100;
  ps[5].X := 25;
  ps[5].Y := 75;

  Polyline(Canvas.Handle, ps, 6);
end;
