调整形状内部路径的大小 [英] Resize of a path inside a shape

问题描述

大家好！....

 

我有一个关于调整内部路径大小的问题一个形状。我会尝试尽可能清楚。

I have a question about the resize of a path inside a shape. I'll try to be as clear as possible.

Inside Blend我在（在LayoutGrid内）绘制一个Circle。然后我绘制另一个圆圈，我使用3个点通过相交操作提取圆的一部分。

Inside Blend I draw (inside the LayoutGrid) a Circle. Then i draw another circle and i use 3 points to extract, through an Intersect operation, a section of a circle.

现在我希望此部分围绕背景中心旋转圆圈（如在雷达效果中）... 

Now i'd like this section to rotate around the center of the background circle (as in a radar effect)... 

除了我仍然必须实现的所有依赖属性。我不明白为什么，当我在应用程序中使控件更大时，扇区调整的方式与背景中的圆圈不一致....

apart from all the dependency properties that i still have to implement. I don't get why, when i make the control bigger inside an application, the sector resize in a way not consistent with the circle in background....

推荐答案

尺寸椭圆和包含路径的网格不一样，所以当你调整它们的大小时，它们在不同的尺度上。

The sizes of the ellipse and the grid containing the path aren't the same, so when you resize both of them they are on different scales.
