Using a XAML Image as a WPF Window background

background, image, window, wpf, xaml

Solution

Try this

<Window.Resources>
    <Canvas x:Key="Background2">
        <!-- Ebene 1/<Path> -->
        <Path Fill="#ff000000" Data="F1 M 841.890,595.275 L 0.000,595.275 L 0.000,0.000 L 841.890,0.000 L 841.890,595.275 Z"/>
        <!-- Ebene 1/<Path> -->
        <Path Data="F1 M 265.910,218.277 C 265.910,169.332 223.865,129.655 172.000,129.655 C 120.135,129.655 78.090,169.332 78.090,218.277 C 78.090,267.222 120.135,306.898 172.000,306.898 C 223.865,306.898 265.910,267.222 265.910,218.277 Z">
            <Path.Fill>
                <RadialGradientBrush MappingMode="Absolute"
                           GradientOrigin="172.733,217.234"
                           Center="172.733,217.234"
                           RadiusX="81.912" RadiusY="81.912">
                    <RadialGradientBrush.GradientStops>
                        <GradientStop Offset="0.00" Color="#ff0d4976"/>
                        <GradientStop Offset="0.41" Color="#ff06243b"/>
                        <GradientStop Offset="1.00" Color="#ff000000"/>
                    </RadialGradientBrush.GradientStops>
                    <RadialGradientBrush.Transform>
                        <MatrixTransform 
                             Matrix="1.146,0.000,0.000,1.082,-26.038,-16.750" />
                    </RadialGradientBrush.Transform>
                </RadialGradientBrush>
            </Path.Fill>
        </Path>
    </Canvas>
</Window.Resources>

<Grid >
    <Grid.Background>
        <VisualBrush Stretch="Fill" Visual="{StaticResource Background2}" />
    </Grid.Background>
</Grid>

You will just have to make a couple of changes to move the resource to your resource dictionary if absolutely necessary.

Problem

Any suggestions how to go about having a XAML vector image as a Window background? There's plenty of code showing this with jpg's but I'd prefer a vector based image. Having it as a resource would be a bonus too but I'm stumped as to the best approach. ``` <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Viewbox x:Key="Background2" Stretch="Fill"> <Canvas >  <Path Fill="#ff000000" Data="F1 M 841.890,595.275 L 0.000,595.275 L 0.000,0.000 L 841.890,0.000 L 841.890,595.275 Z"/>  <Path Data="F1 M 265.910,218.277 C 265.910,169.332 223.865,129.655 172.000,129.655 C 120.135,129.655 78.090,169.332 78.090,218.277 C 78.090,267.222 120.135,306.898 172.000,306.898 C 223.865,306.898 265.910,267.222 265.910,218.277 Z"> <Path.Fill> <RadialGradientBrush MappingMode="Absolute" GradientOrigin="172.733,217.234" Center="172.733,217.234" RadiusX="81.912" RadiusY="81.912"> <RadialGradientBrush.GradientStops> <GradientStop Offset="0.00" Color="#ff0d4976"/> <GradientStop Offset="0.41" Color="#ff06243b"/> <GradientStop Offset="1.00" Color="#ff000000"/> </RadialGradientBrush.GradientStops> <RadialGradientBrush.Transform> <MatrixTransform Matrix="1.146,0.000,0.000,1.082,-26.038,-16.750" /> </RadialGradientBrush.Transform> </RadialGradientBrush> </Path.Fill> </Path> </Canvas> </Viewbox> </ResourceDictionary> ``` The Resource code above works fine if you remove the Viewbox. The code for the window is :- ``` <Window x:Class="Window2" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window2" Height="700" Width="800"> <Window.Resources> <ResourceDictionary Source="Resources/Dictionary2.xaml" /> </Window.Resources> <Grid> <StaticResource ResourceKey="Background2"/> </Grid> </Window> ```
