Wpf 是否将几何图形/路径转换为小型语言字符串？

跟踪如何在WPF中以编程方式将路径字符串转换为路径对象并不困难，但是是否有一个内置函数可以将几何体或路径转换回mini语言中的字符串？

编辑：刚才我想应该有一个名为，确实有。只需创建其中一个，并在要转换的几何体上使用

您可以使用该类将对象输出为XAML，几何体将自动简化为迷你语言

e、 g.如果这是您的输入：

<DrawingImage x:Name="segmentsDrawing">
    <DrawingImage.Drawing>
        <DrawingGroup>

            <GeometryDrawing Brush="Red">
                <GeometryDrawing.Pen>
                    <Pen Brush="Black" />
                </GeometryDrawing.Pen>
                <GeometryDrawing.Geometry>
                    <PathGeometry>
                        <PathFigure StartPoint="100,100">
                            <PathFigure.Segments>
                                <LineSegment Point="100,0"/>
                                <ArcSegment Point="186.6,150"  SweepDirection="Clockwise" Size="100,100"/>
                                <LineSegment Point="100,100"/>
                            </PathFigure.Segments>
                        </PathFigure>
                    </PathGeometry>
                </GeometryDrawing.Geometry>
            </GeometryDrawing>

            <GeometryDrawing Brush="Blue">
                <GeometryDrawing.Pen>
                    <Pen Brush="Black"/>
                </GeometryDrawing.Pen>
                <GeometryDrawing.Geometry>
                    <PathGeometry>
                        <PathFigure StartPoint="100,100">
                            <PathFigure.Segments>
                                <LineSegment Point="186.6,150"/>
                                <ArcSegment Point="13.4,150" SweepDirection="Clockwise" Size="100,100"/>
                                <LineSegment Point="100,100"/>
                            </PathFigure.Segments>
                        </PathFigure>
                    </PathGeometry>
                </GeometryDrawing.Geometry>
            </GeometryDrawing>

            <GeometryDrawing Brush="Green">
                <GeometryDrawing.Pen>
                    <Pen Brush="Black"/>
                </GeometryDrawing.Pen>
                <GeometryDrawing.Geometry>
                    <PathGeometry>
                        <PathFigure StartPoint="100,100">
                            <PathFigure.Segments>
                                <LineSegment Point="13.4,150"/>
                                <ArcSegment Point="100,0" SweepDirection="Clockwise" Size="100,100"/>
                                <LineSegment Point="100,100"/>
                            </PathFigure.Segments>
                        </PathFigure>
                    </PathGeometry>
                </GeometryDrawing.Geometry>
            </GeometryDrawing>
        </DrawingGroup>
    </DrawingImage.Drawing>
</DrawingImage>

…您将获得以下信息：

                    </GeometryDrawing.Pen>
                    <GeometryDrawing.Geometry>
                        <PathGeometry Figures="M100,100L100,0A100,100,0,0,1,186.6,150L100,100" />
                    </GeometryDrawing.Geometry>
                </GeometryDrawing>
                <GeometryDrawing Brush="#FF0000FF">
                    <GeometryDrawing.Pen>

所有的

PathGeometry

现在都是迷你语言。如果您想在应用程序中立即使用它，我想您可以将它写入

MemoryStream

，然后通过从中创建

XmlDocument

来获取数据。

我想不会，因为这是另一种方式：迷你语言被解析到几何体中。“了解如何在WPF中以编程方式将路径字符串转换为路径对象并不难”是否要共享一些资源？当然！
