Question

YO，我有一个长图像（125x8000像素），我正在向下翻译，一旦它到达某一点，我想使用相同的图像，并将其直接放在翻译图像的顶部，所以它似乎是一个连续的流，永远向下。所以就像翻译的中途一样，我在第一张图片的顶部添加了一个图像副本。并重复。

或者，如果我可以以某种方式使用一个图像并循环它，就好像它是圆形或轮子。这是老虎机。我没有给出代码，因为它的最高机密（不是真的），但到目前为止这是我的xaml：

任何有关如何使其显示为连续性的想法或建议都会很棒。

这样的事情应该有效：

<Rectangle>
    <Rectangle.Fill>
        <ImageBrush
            ImageSource="E:/fruit_roll.png" TileMode="Tile"
            Viewport="0,0,125,8000" ViewportUnits="Absolute">
            <ImageBrush.Transform>
                <TranslateTransform/>
            </ImageBrush.Transform>
        </ImageBrush>
    </Rectangle.Fill>
    <Rectangle.Triggers>
        <EventTrigger RoutedEvent="Loaded">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation
                        Storyboard.TargetProperty="Fill.Transform.Y"
                        To="-8000" Duration="0:0:5"
                        RepeatBehavior="Forever"/>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Rectangle.Triggers>
</Rectangle>

WPF重新使用\替换图像;动画
