  • 黑色方框背景色代码:

灰色方格背景DrawingBrush作为Bord贴图填充
ps:其中Stretch默认为Fill,所有AlignmentX/Y值无用,当Stretch为None,ViewBox和Viewport具有不同带大小及Stretch为Uniform或UniformToFill,而纵横比不同时将使用AlignmentX/Y。

<DrawingBrush x:Key="MyGridBrushResource"
  Viewport="0,0,10,10" ViewportUnits="Absolute"
  TileMode="Tile" Opacity="0.5"
  AlignmentX="Left" AlignmentY="Top"
  presentationOptions:Freeze="True">
        <DrawingBrush.Drawing>
            <DrawingGroup>
                <GeometryDrawing Geometry="M0,0 L1,1" Brush="#44CCCCFF" />
                <GeometryDrawing Geometry="M0,0 L1,0 1,0.05 0.05,0.05 0.05,1 0,1Z" 
       Brush="Gray" />
            </DrawingGroup>
        </DrawingBrush.Drawing>
    </DrawingBrush>

箭头绘图代码:

  1. 设置Marin的不同值,使箭头方框X轴不同位置
  2. 使用DrawingBursh里的3个Geometry组成箭头形状,贴图填充方框区域
<DrawingBrush x:Key="ArrowBackgroundBrush" Opacity="0.5"
  Viewbox="0,0,1,1" Viewport="0,0,10,20" ViewportUnits="Absolute"
  TileMode="Tile" presentationOptions:Freeze="True">
    <DrawingBrush.Drawing>
        <DrawingGroup>
            <GeometryDrawing Geometry="M0,0 L1,0, 1,0.5" Brush="#9999FF" />
            <GeometryDrawing Geometry="M0,0 L1,0.5, 0,1">
                <GeometryDrawing.Brush>
                    <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
                        <GradientStop Offset="0.0" Color="#9999FF" />
                        <GradientStop Offset="1.0" Color="Transparent" />
                    </LinearGradientBrush>
                </GeometryDrawing.Brush>
            </GeometryDrawing>
            <GeometryDrawing Geometry="M0,1 L1,1, 1,0.5" Brush="#9999FF" />
        </DrawingGroup>
    </DrawingBrush.Drawing>
</DrawingBrush>

Button点击事件触发右侧方框动画代码:
简单的故事版动画目标元素、目标属性、持续时间、From、By、To等组合构成了不同的动画效果
