我们如何在 WPF 中为圆弧段设置动画。下面是附上的代码。
PathGeometry pg = new PathGeometry();
PathFigure pf = new PathFigure();
LineSegment ls1 = new LineSegment();
LineSegment ls2 = new LineSegment();
ArcSegment arc = new ArcSegment();
double xc = canvas.Width / 2 - 50 + dx;
double yc = canvas.Height / 2 + dy;
double r = 0.7 * xc; // To control the Explosion generally for all the slices
pf.IsClosed = true;
pf.StartPoint = new Point(xc, yc);
pf.Segments.Add(ls1);
pf.Segments.Add(arc);
pf.Segments.Add(ls2);
pg.Figures.Add(pf);
path.Data = pg;
arc.IsLargeArc = isLargArc;
ls1.Point = new Point(xc + r * Math.Cos(startAngle), yc + r * Math.Sin(startAngle));
arc.SweepDirection = SweepDirection.Clockwise;
arc.Point = new Point(xc + r * Math.Cos(endAngle), yc + r * Math.Sin(endAngle));
arc.Size = new Size(r, r);
ls2.Point = new Point(xc + r * Math.Cos(endAngle), yc + r * Math.Sin(endAngle));
Duration duration = new Duration(TimeSpan.FromSeconds(5));
pau = new PointAnimationUsingPath();
pau.PathGeometry = pg;
pau.FillBehavior = FillBehavior.Stop;
pau.Duration = new Duration(TimeSpan.FromSeconds(5));
我试图让圆弧段从一个位置到另一个位置进行动画处理。有一个弧段列表，它们一个接一个地动画。
