WPF 用 DrawingBrush实现图形的平铺

WPF平铺图像，一般用到 DrawingBrush 来实现对图形、图形的平铺，查阅了 微软官方文档的 DrawingBrush  属性

 

 

创建一个 DrawingBrush，其中： 

TileMode="Tile"设置了改画刷为平铺的属性

<DrawingBrush x:Key="test" Stretch="None" Viewport="0,0,78,78" ViewportUnits="Absolute" TileMode="Tile">
        <DrawingBrush.Drawing>
            <DrawingGroup>
                <DrawingGroup.Children>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <RectangleGeometry Rect="0,0,78,78" />
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Pen>
                            <Pen Brush="{StaticResource GridLineBrush}" Thickness="3"/>
                        </GeometryDrawing.Pen>
                    </GeometryDrawing>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <GeometryGroup>
                                <LineGeometry StartPoint="0.5,19.5" EndPoint="77.5,19.5" />
                                <LineGeometry StartPoint="0.5,39" EndPoint="77.5,39" />
                                <LineGeometry StartPoint="0.5,58.5" EndPoint="77.5,58.5" />
                                <LineGeometry StartPoint="19.5,0.5" EndPoint="19.5,77.5" />
                                <LineGeometry StartPoint="39,0.5" EndPoint="39,77.5" />
                                <LineGeometry StartPoint="58.5,0.5" EndPoint="58.5,77.5" />
                            </GeometryGroup>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Pen>
                            <Pen Brush="{StaticResource GridLineBrush}" Thickness="1"/>
                        </GeometryDrawing.Pen>
                    </GeometryDrawing>
                </DrawingGroup.Children>
            </DrawingGroup>
        </DrawingBrush.Drawing>
    </DrawingBrush>

 

画刷会自动适应平铺到窗体一样的大小，效果图如下：
