c# – WPF圆角 – 可能是拐角处的一致渐变吗？

我已经制作了一个渐变,我非常喜欢表达式混合,我正在努力研究如果我可以围绕一个角落制作渐变曲线,给我一个带渐变的圆角边框效果.

问题是我不能使用普通边框,因为渐变不一致.

我想出了以下内容,这有助于展示我的想法：

<Grid x:Name="grid" >
    <Border
        BorderThickness="0,0,40,40"
        CornerRadius="0,0,40,0"
        Padding="2" Height="60" VerticalAlignment="Bottom" Width="65" HorizontalAlignment="Right" >
        <Border.BorderBrush>
            <RadialGradientBrush>
                <RadialGradientBrush.RelativeTransform>
                    <TransformGroup>
                        <ScaleTransform CenterX="0.5" CenterY="0.5" ScaleX="2.058" ScaleY="2.177"/>
                        <SkewTransform AngleX="0" AngleY="0" CenterX="0.5" CenterY="0.5"/>
                        <RotateTransform Angle="-119.481" CenterX="0.5" CenterY="0.5"/>
                        <TranslateTransform X="0.209" Y="0.52"/>
                    </TransformGroup>
                </RadialGradientBrush.RelativeTransform>
                <GradientStop Color="#FF000000" Offset="0"/>
                <GradientStop Color="#000A0A0A" Offset="1"/>
                <GradientStop Color="#6B050505" Offset="0.829"/>
                <GradientStop Color="#BB020202" Offset="0.763"/>
            </RadialGradientBrush>
        </Border.BorderBrush>
    </Border>
    <Rectangle VerticalAlignment="Stretch" Height="100" Width="40" HorizontalAlignment="Right" Margin="0,0,0,60" StrokeThickness="0" Panel.ZIndex="0">
        <Rectangle.Fill>
            <LinearGradientBrush EndPoint="-0.025,0.5" StartPoint="1,0.5">
                <GradientStop Color="#FF000000" Offset="0"/>
                <GradientStop Color="#000A0A0A" Offset="1"/>
                <GradientStop Color="#6B050505" Offset="0.829"/>
                <GradientStop Color="#BB020202" Offset="0.763"/>
            </LinearGradientBrush>
        </Rectangle.Fill>
    </Rectangle>
    <Rectangle VerticalAlignment="Bottom" Height="40" Width="100" HorizontalAlignment="Stretch" Margin="0,0,65,0">
        <Rectangle.Fill>
            <LinearGradientBrush EndPoint="0.5,0" StartPoint="0.5,1">
                <GradientStop Color="#FF000000" Offset="0"/>
                <GradientStop Color="#000A0A0A" Offset="1"/>
                <GradientStop Color="#6B050505" Offset="0.829"/>
                <GradientStop Color="#BB020202" Offset="0.763"/>
            </LinearGradientBrush>
        </Rectangle.Fill>
    </Rectangle>
</Grid>

有没有办法像我在想的那样在拐角处弯曲？我在网上看到了一个互相嵌套边框的建议,但这对我来说也没有好处,因为渐变会让生活变得困难.

解决方法:

您可能想查看Charles Petzolds article on Graphical Paths with Gradient Colors,其中他讨论了类似的问题.
