[WPF C#} Polygon filled with video

[James Rose]

Hello gang,

I am in need to make a polygon object that I will with a video. I have this working fine, however the fill of the video using the

<VisualBrush Stretch="UniformToFill">

including "None", "Fill", "Uniform" or "UniformToFill" is not filling the polygon as I would like.

Here is the XAML code for creating the polygon

        <Polygon Name="vlcPolygon" Points="500,300, 500,250, 770,200 770,440" Stroke="Black" StrokeThickness="4" >
            <Polygon.Fill>
                <VisualBrush Stretch="UniformToFill">
                    <VisualBrush.Visual>
                        <Image Source="{Binding VideoSource, ElementName=vlcPlayer}" />
                    </VisualBrush.Visual>
                </VisualBrush>
            </Polygon.Fill>
        </Polygon>

Any thoughts?

Hi James.

Saw your 2011 post while searching for wpf polygon fill video ....
You've probably moved on to other things.
Thought I'd share my experience and ask what your experience was and is.

Are you still working with video for apps/web/games/ just fun?

 

I experimented with it in 2009 (using F# and WPF no XAML) --

Recently trying to get "replay" or "loop"  found this MSDN XAML and hacked .mp4
