如何在WPF中获得围绕多个形状的单个边界矩形 [英] How to get a single Bounding rectangle around multiple shapes in WPF

问题描述

我在画布上有多个形状.我需要围绕所有选定的形状生成一个边界矩形，而无需更改它们的现有位置.而且我也应该能够调整大小和旋转它们.当我调整整个组的大小时，比例应适用于内部的所有形状.现在，我无法选择多个形状，也可以一次调整它们的大小，但是对于这些选定的形状，我没有公共的边界矩形.
我是WPF的初学者.请发布有关此问题的任何想法.提前谢谢.

Hi, I have multiple shapes on canvas. I need to generate a bounding rectangle around all the selected shapes without altering their existing positions. And I should be able resize and rotate them as well. When i resize the whole group the scale should apply to all the shapes inside. Right now Im able to select multiple shapes and able to resize them at a time as well, but i dont have common bounding rectangle for those selected shapes.
Im a beginner for WPF.Kindly post any ideas regarding the issue. Thanks in advance.

推荐答案

请查看这是否适合您的解决方案:

<边框
BorderThickness ="2"
BorderBrush ="Black">
<画布>
您的形状
</画布>
</Border>

在边界上使用ScaleTransform.

(如果打算使用ScaleTransform + LinearTransform，请将它们包装在TransformGroup中)

示例:
< Border BorderBrush ="Black" BorderThickness ="2" Height ="200" Width ="200">
<画布>
< Ellipse Width ="150" Height ="150" StrokeThickness ="2" Stroke ="Black"/>
</画布>
< Border.RenderTransform>
< ScaleTransform ScaleX ="0.5" ScaleY ="0.5"/>
</Border.RenderTransform>
</Border>

让我知道是否需要进一步的澄清，将很乐意为您提供帮助！

如果解决，请标记为答案！ :)

谢谢！

Please see if this suits your solution:

<Border
BorderThickness="2"
BorderBrush="Black">
<Canvas>
Your shapes
</Canvas>
</Border>

Use ScaleTransform on your border.

(If you intend to use ScaleTransform + LinearTransform, wrap them in TransformGroup)

Example:
<Border BorderBrush="Black" BorderThickness="2" Height="200" Width="200">
<Canvas>
<Ellipse Width="150" Height="150" StrokeThickness="2" Stroke="Black"/>
</Canvas>
<Border.RenderTransform>
<ScaleTransform ScaleX="0.5" ScaleY="0.5"/>
</Border.RenderTransform>
</Border>

Let me know if you need any more clarifications, will be happy to help!

Mark as answer if this solves! :)

Thanks guys for your replies..... Anyways I got the solution for my problem. I got code for grouping and rotation and resize separately. I did some work and able to mix them both into one. And trying to make the code more fool proof. Here are the links that helped me. Thanks once again.
