方格效果:

WPF Geometry="M0,0 L1,0 1,0.1, 0,0.1Z" 画方格背景图-LMLPHP

前端代码如下:

<Window x:Class="WpfApp1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApp1"
mc:Ignorable="d"
Title="MainWindow" Height="" Width="">
<Window.Resources>
<!--自定义格式的背景的具体定义-->
<!--Viewport="0,0,50,50" 起点坐标为0, 长为50宽为50像素的矩形-->
<DrawingBrush x:Key="MyGridBrushResource" Viewport="0,0,50,50" ViewportUnits ="Absolute" TileMode="Tile">
<DrawingBrush.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
<!--画横线-->
<GeometryDrawing Geometry="M0,0 L1,0 1,0.1, 0,0.1Z" Brush="#CCCCFF" />
<!--画竖线-->
<GeometryDrawing Geometry="M0,0 L0,1 0.1,1, 0.1,0Z" Brush="#CCCCFF" />
</DrawingGroup.Children>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush> <Style x:Key="MyCanvasStyle">
<!--自定义格式的背景为 MyGridBrushResource-->
<Setter Property="Canvas.Background" Value="{StaticResource MyGridBrushResource}"/>
</Style>
</Window.Resources> <Grid>
<!--放置一个画布 Canvas 格式为自定义格式MyCanvasStyle -->
<Canvas Name="_myCanvas" Style="{StaticResource MyCanvasStyle}" />
</Grid>
</Window>
Geometry="M0,0 L1,0 1,0.1, 0,0.1Z" 此语法中M是移动命令,L是直线命令,Z是结束命令,详细资料参考官网https://docs.microsoft.com/zh-cn/dotnet/framework/wpf/graphics-multimedia/path-markup-syntax#the-close-command
M0,0 L1,0 1,0.1, 0,0.1Z此语法中的数值都是比例的意思,(0,0)->(1,0)->(1,0.1)->(0,0.1)画了一个矩形,横坐标的1是1*50 = 50,0是0*50 = 0,0.1就是0.1*50 = 5纵坐标以此类推。(矩形 Viewport="0,0,50,50")

<!--画横矩形-->
<GeometryDrawing Geometry="M0,0 L1,0 1,0.1, 0,0.1Z" Brush="#CCCCFF" />
<!--画竖矩形-->
<GeometryDrawing Geometry="M0,0 L0,1 0.1,1, 0.1,0Z" Brush="#CCCCFF" />

效果图

WPF Geometry=&quot;M0,0 L1,0 1,0.1, 0,0.1Z&quot; 画方格背景图-LMLPHP

TileMode="Tile" Tile是瓦片的意思,把TileMode设为None就是上图效果,设为Tile瓦片模式,就会横向纵向像瓦片一样展开,就是第一张图的效果。

我们把第三个点(0,0)->(1,0)->(1,0.1)->(0,0.1)纵坐标的0.1改成0.5比例的话(0,0)->(1,0)->(1,0.5)->(0,0.1)单个效果如下:

WPF Geometry=&quot;M0,0 L1,0 1,0.1, 0,0.1Z&quot; 画方格背景图-LMLPHP

TileMode="Tile"瓦片模式效果

WPF Geometry=&quot;M0,0 L1,0 1,0.1, 0,0.1Z&quot; 画方格背景图-LMLPHP

以上纯属个人理解,如有错误,望请更正!
