提问by Metro
How can I create a brush (DrawingBrush) for stripes as shown in the blog:

I can't use it because it uses scale transform, which means if the UI element is small, the stripes are pretty much not visible or too close together.
我不能使用它，因为它使用缩放变换，这意味着如果 UI 元素很小，条纹几乎不可见或靠得太近。
I can't use image brush because I need to bind the colors.
我不能使用图像刷，因为我需要绑定颜色。

Creates downward 45 degree angle stripe pattern. Alter viewport to change size of stripes
创建向下 45 度角条纹图案。改变视口以改变条纹的大小
<DrawingBrush Stretch="UniformToFill" ViewportUnits="Absolute" Viewport="0,0,10,10" TileMode="Tile">
<DrawingBrush.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
<GeometryDrawing Brush="Black">
<GeometryDrawing.Geometry>
<GeometryGroup FillRule="Nonzero">
<PathGeometry>
<PathFigure StartPoint="0,0">
<LineSegment Point="100,0"/>
<LineSegment Point="100,100"/>
<LineSegment Point="0,100"/>
</PathFigure>
</PathGeometry>
</GeometryGroup>
</GeometryDrawing.Geometry>
</GeometryDrawing>
<GeometryDrawing Brush="#FF404040">
<GeometryDrawing.Geometry>
<GeometryGroup FillRule="Nonzero">
<PathGeometry>
<PathFigure StartPoint="0,0">
<LineSegment Point="25,0"/>
<LineSegment Point="100,75"/>
<LineSegment Point="100,100"/>
<LineSegment Point="75,100"/>
<LineSegment Point="0,25"/>
<LineSegment Point="0,0"/>
</PathFigure>
<PathFigure StartPoint="75,0">
<LineSegment Point="100,25"/>
<LineSegment Point="100,0"/>
</PathFigure>
<PathFigure StartPoint="0,75">
<LineSegment Point="25,100"/>
<LineSegment Point="0,100"/>
</PathFigure>
</PathGeometry>
</GeometryGroup>
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingGroup.Children>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush>
Alternatively you could bind the scale transform to the height and width of the control using multibinding. Then with a converter, you alter the scale to the max of height or width, then the stripes will remain the same size.
或者，您可以使用多重绑定将缩放变换绑定到控件的高度和宽度。然后使用转换器，将比例更改为高度或宽度的最大值，然后条纹将保持相同的大小。

Just use MappingMode="Absolute":
只需使用 MappingMode="Absolute"：
<LinearGradientBrush MappingMode="Absolute" x:Key="HatchBrush" StartPoint="0,0" EndPoint="4,4" SpreadMethod="Repeat">
<GradientStop Offset="0" Color="LightCoral"/>
<GradientStop Offset="0.75" Color="LightCoral"/>
<GradientStop Offset="0.75" Color="Gray"/>
<GradientStop Offset="1" Color="Gray"/>
</LinearGradientBrush>
