WPF允许使用 变换 规模（的 ScaleTransform ），旋转（的 RotateTransform ），歪斜（的 SkewTransform ）等任何的 FrameworkElement的 。

WPF allows to use subclasses of Transform to scale(ScaleTransform), rotate(RotateTransform), skew (SkewTransform) and so on any FrameworkElement.

但我不能看到如何进行一些裁剪 FrameworkElement的 使用这些。有什么办法如何裁剪可以说的标签宽度30像素，因此将像它的宽度为20像素？

But I cannot see how to crop some FrameworkElement using these. Is there any way how to crop lets say a Label of width 30px so it will behave as if its width was 20px?

要更确切的说：我想这样做铺设之前，使标签将布局为如果它的宽度为20。但我希望它是呈现充分所以最后10个像素也将被渲染（可能是重叠的其他元素）。我怎样才能做到这一点？

To be more exact: I want to do this before laying out so that the Label would be laid out as if its width was 20. But I want it to be rendered fully so the last 10 pixels will be rendered too (possibly overlapping other elements). How can I do this ?

为什么我需要这个？我想打H.B.'s回答我的问题Create在WPF吉他和弦编辑，提供字距。

Why do I need this ? I want to make H.B.'s answer to my question Create guitar chords editor in WPF to work with kerning.

推荐答案

使用负保证金标签上，如保证金=0,0，-10,0使标签10像素右侧短，布局明智的。 （为prevent重叠把它放在一个容器中，并设置 ClipToBounds =真）

Use a negative Margin on the label, e.g. Margin="0,0,-10,0" makes the Label 10 pixels shorter on the right, layout-wise. (To prevent overlap put it in a container and set ClipToBounds="True")
