Silverlight、DeepZoom 缩放动画
当我在 Silverlight 中设置 Deepzoom 图像的 ViewportWidth 时，缩放级别变化得非常快。有没有办法可以设置这个缩放动画应该花费的时间？
谢谢
When I set the ViewportWidth of a Deepzoom image in Silverlight the zoom level changes very quickly. Is there a way I can set the time this zooming animation should take?
Thanks

唯一的方法是将
UseSprings设置为 false，并自行为ViewportWidth的值设置动画。如果您想保持平移的“弹簧”动画，这也会迫使您在执行平移操作时对ViewportOrigin进行动画处理。您需要测试其性能。 MultiscaleImage 很可能会以不同于这些属性在外部进行动画处理的方式优化其自身的动画。
The only way to do that would be to set
UseSpringsto false and animate the value ofViewportWidthyourself. This will also force you to animate the theViewportOriginas well when performing panning operations if you want to maintain the "spring" animation of panning.You would need to test the performance of this. It could well be that MultiscaleImage may optimise its own animations differently than when these properties are being animated externally.
尝试使用 MultiScaleImage.UseSprings = true 和 ZoomAboutLogicalPoint() 方法。
Try using the MultiScaleImage.UseSprings = true and the ZoomAboutLogicalPoint() method.
虽然不能直接设定时间，但每个“Spring”正好需要1.5秒。因此，如果您愿意，您可以保留弹簧，然后计算当前视口宽度与您想要的视口宽度之间的差异，并尝试以这种方式调整计时。话虽这么说，它可能看起来很尴尬，所以你必须先测试一下。
Although you cannot set the timing directly, each "Spring" takes exactly 1.5 seconds. So, if you wanted to, you could leave springs on, and then calculate the difference between the current viewportwidth, the viewport width you want to go to, and try and massage the timing this way. That being said, it may look awkward, so you'd have to test it first.
