WPF中的模式画笔

Question

我正在努力创造各种画笔来填充各种形状或作为背景.以下是我正在努力创建的一些模式:

1. <<<< >>>>
2. <| <| <| <|> |> |> |>
3. ////////
4. \\\\
5. ||||||||

我已经能够创建\\\,//////和|||||| 线性渐变,但前两个是导致我的问题.顺便说一句,第二个是三角形.

任何建议或帮助将不胜感激.

Answer 1

你需要使用一个TileBrush.用一个Drawing或一个图像定义一个图块的图案,并用DrawingBrush或重复它ImageBrush.关于这个主题的文档相当广泛,这些例子应该给你一些想法

Answer 2

您可以使用绘图笔刷创建复合渐变.例如,这里是一个菱形渐变,您可以将其粘贴到窗口中进行测试:

<Window.Background>
    <DrawingBrush>
        <DrawingBrush.Drawing>
            <DrawingGroup>
                <DrawingGroup.Children>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <RectangleGeometry Rect="0,0,100,100"/>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Brush>
                            <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                                <GradientStop Offset="0.0" Color="Black" />
                                <GradientStop Offset="1.0" Color="White" />
                            </LinearGradientBrush>
                        </GeometryDrawing.Brush>
                    </GeometryDrawing>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <RectangleGeometry Rect="100,0,100,100"/>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Brush>
                            <LinearGradientBrush StartPoint="1,0" EndPoint="0,1">
                                <GradientStop Offset="0.0" Color="Black" />
                                <GradientStop Offset="1.0" Color="White" />
                            </LinearGradientBrush>
                        </GeometryDrawing.Brush>
                    </GeometryDrawing>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <RectangleGeometry Rect="0,100,100,100"/>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Brush>
                            <LinearGradientBrush StartPoint="0,1" EndPoint="1,0">
                                <GradientStop Offset="0.0" Color="Black" />
                                <GradientStop Offset="1.0" Color="White" />
                            </LinearGradientBrush>
                        </GeometryDrawing.Brush>
                    </GeometryDrawing>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <RectangleGeometry Rect="100,100,100,100"/>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Brush>
                            <LinearGradientBrush StartPoint="1,1" EndPoint="0,0">
                                <GradientStop Offset="0.0" Color="Black" />
                                <GradientStop Offset="1.0" Color="White" />
                            </LinearGradientBrush>
                        </GeometryDrawing.Brush>
                    </GeometryDrawing>
                </DrawingGroup.Children>
            </DrawingGroup>
        </DrawingBrush.Drawing>
    </DrawingBrush>
</Window.Background>

ASCII图形表达不够,但也许这就是你所说的<<< >>>:
