How to mask a square image into an image with round corners?

How do I want to implement a Rounded Cornered Mask for my image control . I created a control like this

    <Border x:Name="Border1"  CornerRadius="{Binding CornerRadius,Mode=TwoWay}"  >
            <Image  x:Name="ImageSource1" Background="Transparent" >
            </Image>
    </Border> 
<Border x:Name="MaskBorder1"  BorderBrush="White"  CornerRadius="{Binding CornerRadius,Mode=TwoWay}" BorderThickness="3" />

But I get Control with.

enter image description here

Anyone have an idea to fill the corners with Border color ?

Just pin the image, here is the snippet I'm using

 <Image                               
                            Width="96"
                            Height="96"
                            Stretch="UniformToFill"
                            HorizontalAlignment="Left"
                            VerticalAlignment="Top">
                            <Image.Clip>
                                <EllipseGeometry
                                    Center="48,48"
                                    RadiusX="48"
                                    RadiusY="48" />
                            </Image.Clip>
                        </Image>


For it to work, you need to set Center, RadiusX and RadiusY to half the image size.

I don’t know if this could help? But for image manipulation, I always find the Writeablebitmapex library ! And a good example of masking images can be found here ...



Hope it helps

Not sure what you are using CornerRadius="{Binding CornerRadius,Mode=TwoWay}"

, but I would be interested to see your implementation, after checking the Stecya post here , if this turns out to be what you are looking for.
