在动画中使用时，模糊的TextBlocks [英] Blurred textblocks when used in animations
问题描述
我在模拟使用两个画布之间的动画在Windows商店应用语义变焦效果。然而，当我缩小的的TextBlock 出现在画布上，表现为非常模糊，直到动画完成。
I am simulating the semantic zoom effect in a Windows Store app using animations between two canvas'. However when I "zoom out" the TextBlock that appear on the canvas, appear as VERY blurry until the animation completes.
这只是发生在第一个动画后，该文本是所有后续动画清晰。
This only happens for the first animation, after that the text is clear on all subsequent animations.
我怀疑一个位图缓存类型的问题，但无论是设置 CacheMode参数为位图或空没什么区别。
I suspecting a bitmap caching type issue but either setting the CacheMode to Bitmap or null makes no difference.
是否有可能控制或改变这种任何设置
Are there any settings that can control or change this?
用于动画的XAML是相当简单的，肘节能见度，然后使用一个简单DoubleAnimation是改变X - 放大器的规模;在电网包含了各种图像的Y值。每个电网是视框键，里面是一个自定义的控制（而不是 TemplatedControl - 只是一个普通的老式自定义的）
The XAML used for the animation is fairly straight forward, toggle visibility and then uses a simple DoubleAnimation to change the scale of the X & Y values of the Grid which contain the various images. Inside each Grid is a ViewBox and inside that is a custom control (not a TemplatedControl - just a plain old custom one).

我有一个更简单的场景重现了类似的问题，代码可以从的 GitHub上并看到问题存在这里是一个的视频，注意模糊的文本，当我们从缩小恢复到正常的状态去
I have recreated a similar issue in a much simpler scenario, the code can be obtained from GitHub and to see the issue there here is a video, note the blurry text when we go from zoomed out back to normal state.

推荐答案
这是由设计。文本不中动画/变焦完全呈现。一旦完成，全面渲染调用。这是常见的几乎每一个平台上。如果这是杀了你，你可以动画的图像（这基本上是Direct3D是做）。合理？我希望这回答了你的问题。
This is by design. Text is not full rendered during animations/zooms. Once complete, the comprehensive rendering is invoked. This is common on almost every platform. If this is killing you, you can animate an image (which is basically what Direct3D is doing). Make sense? I hope this answers your question.
