在WPF MVVM中预览PathGeometry的实际图像

Question

在我的应用程序中有一个常见的Icon.xaml文件，其中包含许多具有唯一键名的PathGeometry数字，如下所示。

<PathGeometry x:Key="CloseGeometry" Figures="m 357.0883 499.0572 12.62375 12.6275 5.31375 -5.31625 -12.62625 -12.62625 12.62625 -12.61875 -5.31375 -5.3125 -12.62375 12.62 -12.6325 -12.62 -5.30375 5.3125 12.6175 12.61875 -12.6175 12.62625 5.30375 5.31625 12.6325 -12.6275 z"/>

<PathGeometry x:Key="MinimiseGeometry" Figures="M 0 1, 1 1 "/>

.....

但我的问题是大约有300到400种不同的PathGeometries，很难检查特定类型的Image是否存在。

示例：

如果新的WPF表格由程序员开发，其中s \他需要使用删除图标然后s \他将首先检查Icon.xaml文件是否已经存在，如果没有那么它将被添加。但是这种检查需要手动完成，这很痛苦。

有没有最简单的方法来预览或检查是否存在特定的iamge。

目前，我知道有两个工具可以帮助您预览PathGeometry xaml的数据。

1. XamlPadX

下载：XamlPadX v4.0。

然后将PathGeometry数据（节点“ Figures”的字符串）放入“ Data”内部的值： 接下来，您需要单击左上角的“自动解析”按钮，您可以查看渲染结果（屏幕截图中的红色边框区域）。如下所示，我只是使用您数据中的第二个数据。

1. WPF几何转换工具

下载：WPF Geometry Transformation Tool。 将节点“ Figures”的字符串放入Input Geometry的文本区域中，然后您可以看到结果（屏幕截图中的红色边框区域）。
