How to Render a Path using Geometry

02 Nov 2015, 21:19

The following renders fine in visual studio with the [Has Geometry Here] filled in utilizing a rectangle to contain the resource. How can I modify this code to render using Noesis?

I am attempting to use a icon library that is formatted with the following objects as a static resource for each icon.
    <Canvas x:Key="IconGlobe" >
        <Path Fill="#FFFFFFFF">
            <Path.Data>
                                    <Geometry>[Has Geometry Here]</Geometry>
            </Path.Data>
        </Path>
    </Canvas>
The icons would then be included as a rectangle in the application as follows.
 <Rectangle Style="{StaticResource MediumContent}"  Margin="0,0,10,0">
                    <Rectangle.Fill>
                        <VisualBrush Visual="{StaticResource IconGlobe}"/>
                    </Rectangle.Fill>
                </Rectangle>
This has no issue rendering in Visual Studio or WPF Applications. How can I get the included static resource to render in noesis/what do I need to change tom make them render.

Below is a full example without using static resources for testing purposes.
       
            <Rectangle Width="30" Height="30">
                <Rectangle.Fill>
                    <VisualBrush >
                        <VisualBrush.Visual>
                            <Path Fill="#FFFFFFFF">
                                <Path.Data>

Re: How to Render a Path using Geometry

03 Nov 2015, 10:30

Hi,

Using VisualBrush.Visual with a new visual tree is not supported and it's a known issue. Right now VisualBrush can only be used if you reference a visual that is part of the UI logical tree that is being rendered. For example, the Reflections.xaml we provide in our SDK:
<Grid x:Name="Src" Margin="0,-60,0,0">
...
</Grid>
<Rectangle Height="100" Grid.Row="1">
  <Rectangle.Fill>
    <VisualBrush Visual="{Binding ElementName=Src}".../>
  </Rectangle.Fill>
</Rectangle>
 
I can think of two options to accomplish what you want:

1) If the geometry can be combined into a single StreamGeometry (because only 1 brush is used to draw it), the best option is to share the icon geometries as resources, and then use them directly in a Path:
<Grid>
  <Grid.Resources>
    <Geometry x:Key="IconGlobe">
      m 4.05467 1039.4287 c 0.85504 -5.7384 1.88225 -11.1531 2.28265 -12.0328 0.54267 ...
    </Geometry>
    <Geometry x:Key="IconWorker">
      ...
    </Geometry>
    ...
  </Grid.Resources>

  <StackPanel x:Name="IconBar" Orientation="Horizontal">
    <Path Data="{StaticResource IconGlobe}" Fill="White" Width="30" Height="30" Margin="1"/>
    <Path Data="{StaticResource IconWorker}" Fill="White" Width="30" Height="30" Margin="1"/>
    ...
  </StackPanel>
  ...
</Grid>
2) If the icon uses different paths and brushes, the best option is to use templates, and apply them to simple control elements:
<Grid>
  <Grid.Resources>
    <ControlTemplate x:Key="IconGlobe" TargetType="Control">
      <Viewbox>
        <Canvas Width="64" Height="64">
          <Path Data="m 4.05467 1039.4287 c 0.85504 -5.7384 1.88225 -11.1531 2.28265..." Fill="White" .../>
          <Path Data="..." Fill="Silver" .../>
          ...
        </Canvas>
      </Viewbox>
    </ControlTemplate>
    <ControlTemplate x:Key="IconWorker" TargetType="Control">
      ...
    </ControlTemplate>
    ...
  </Grid.Resources>

  <StackPanel x:Name="IconBar" Orientation="Horizontal">
    <Control Template="{StaticResource IconGlobe}" Width="30" Height="30" Margin="1"/>
    <Control Template="{StaticResource IconWorker}" Width="30" Height="30" Margin="1"/>
    ...
  </StackPanel>
  ...
</Grid> 
Hope this helps ;)

Re: How to Render a Path using Geometry

Is this planned to be resolved? I am for whatever reason unable to get my icons to render using the other methods given. Here is the exact code I am using.

When using the rectangle and visual brush I am getting my icon in visual studio and a xaml page.

When using the control template with a canvas I am not getting it to render in either case.

            <Control Template="{StaticResource IconGlobeMedium}" Width="100" Height="100" Margin="1"/>
            <Control Template="{StaticResource IconGlobeMedium2}" Width="100" Height="100" Margin="1"/>

    <ControlTemplate x:Key="IconGlobeMedium2" TargetType="Control">
        <Viewbox>
            <Canvas Width="100" Height="100">
                <Path Fill="#FFFFFFFF">

Re: How to Render a Path using Geometry

10 Nov 2015, 10:48

Hi,

ControlTemplate objects must be defined inside a ResourceDictionary (or inside the Resources property of an element). And if you are referencing to them as a StaticResource, then you have to define the templates before using them, just as I explained in my previous answer. The following renders perfectly in Blend/VS/Kaxaml:
<Grid
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  Background="Black">

    <Grid.Resources>
        <ControlTemplate x:Key="IconGlobeMedium2" TargetType="Control">
            <Viewbox>
                <Canvas Height="78" Width="78">
                    <Path Canvas.Left="-1" Canvas.Top="-973" Fill="White"

In the previous post I used a Canvas of 100x100 just as an example, because usually when importing a vector geometry to Blend it comes wrapped on a Canvas. But in order to work correctly its size must be set accordingly to Path dimensions, and also set the correct Left and Top properties in the Path.
