我可以为边框的移动制作动画:
private void MoveTo(Border target, double newX, double newY)
{
Vector offset = VisualTreeHelper.GetOffset(target);
var top = offset.Y;
var left = offset.X;
TranslateTransform trans = new TranslateTransform();
target.RenderTransform = trans;
DoubleAnimation anim1 = new DoubleAnimation(0, newY - top, TimeSpan.FromMilliseconds(500));
DoubleAnimation anim2 = new DoubleAnimation(0, newX - left, TimeSpan.FromMilliseconds(500));
trans.BeginAnimation(TranslateTransform.YProperty, anim1);
trans.BeginAnimation(TranslateTransform.XProperty, anim2);
}
但我希望能够设置高度和宽度的增加动画以及放置图像的位置(在我的情况和上面的示例中包含在边框中)。)
这背后有代码吗?
好的,我尝试过缩放转换,但似乎没有做任何事情 - 我需要一个故事板吗?
private void Zoom(Border target)
{
TranslateTransform trans = new TranslateTransform();
target.RenderTransform = trans;
DoubleAnimation anim1 = new DoubleAnimation(1, 2, TimeSpan.FromMilliseconds(1000));
DoubleAnimation anim2 = new DoubleAnimation(1, 2, TimeSpan.FromMilliseconds(1000));
trans.BeginAnimation(ScaleTransform.ScaleXProperty, anim1);
trans.BeginAnimation(ScaleTransform.ScaleYProperty, anim2);
}

最好使用缩放变换进行缩放,但如果您坚持使用W / H动画,则可以执行此操作,因为这些是普通DP,您可以使用标准DoubleAnimation / DoubleAnimationUsingKeyFrames为它们设置动画。 像
这样的东西DoubleAnimation doubleAnimation = new DoubleAnimation(100, 200, new Duration(TimeSpan.FromMilliseconds(500)));
this.BeginAnimation(FrameworkElement.WidthProperty, doubleAnimation);

使用ScaleTransform
,无需Height
& Width
动画,ScaleTransform
会影响您的边框VisualTree
,因此内部图像也会被拉伸。
private void Zoom(Border target)
{
ScaleTransform trans = new ScaleTransform();
target.RenderTransform = trans;
// if you use the same animation for X & Y you don't need anim1, anim2
DoubleAnimation anim = new DoubleAnimation(1, 2, TimeSpan.FromMilliseconds(1000));
trans.BeginAnimation(ScaleTransform.ScaleXProperty, anim);
trans.BeginAnimation(ScaleTransform.ScaleYProperty, anim);
}
