WPF 使用 Canvas 作为 ImageSource
WPF use Canvas as ImageSource
我是 WPF 的新手，正在尝试构建一个带有工具栏和图标的基本应用程序。我正在测试来自 Infragistics 的 XamRibbon 并且功能区上显示的 ButtonTool 需要 ImageSource 来显示如下图像：
<igRibbon:ButtonTool Caption="Edit"
igRibbon:RibbonGroup.MaximumSize="ImageAndTextLarge"
LargeImage="{StaticResource stop}"
SmallImage="{StaticResource stop}" />
我的字典中定义了一个 XAML 图标，键为 'stop'，但我使用的图标都是 Canvas 形式，如下所示：

如何将 Canvas XAML 转换为可以用作 ImageSource 的内容，例如 DrawingImage？我希望这是有道理的。
我不使用 Infragistics 控件，但我相信它们遵循标准 WPF 控件。
我使用了image控件并尝试显示您的canvas路径图像。
从资源canvas路径中定义Geometry
