How can i set the GrayScale for an XAML- Vector Graphic

Hi @all,

i develop a WPF Application with many controls, the have images as content.
The images i have exportet from Expression Graphic Designer as XAML in a
resource dictionary. This resource dictionary i have bind as new resource in
my window. For example:
<Window.Resources>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Icons.xaml"/>
</ResourceDictionary.MergedDictionaries>
</Window.Resources>

OK. For my button i use one of the many ControlTemplates with x:Key. this is
in the Icons.xaml file contained. For example:

<Button>
<StackPanel>
<ContentControl Template ="{StaticResource MyOpenImage}"
Width="20" Height="20"/>
</StackPanel>
</Button>

My goal is it to format the colored resource vector image to an grayscale.
so i think it look disabled.

How can i do this?

Thank you all for help

best greedings and a nice day

Hi people,


i think i found a solution. ok, at hard work i have change the type from my
vector- graphic in the resource dictionary file.

For example:

OLD Version ResourceDictionary:

<ControlTemplate x:Key="MyOpenImage">
<Viewbox Stretch="Uniform" >
<Canvas Width="10.719238" Height="10.718750">
<Canvas>
......
</ControlTemplate>

I can use that only with a content control. That is not which I needs.

NEW Version ResourceDictionary:

<DrawingImage x:Key="MyOpenImage">
<DrawingImage.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
....
</DrawingImage>

Now i can use this with an image control. For example:
.....
<Window.Resources>
<!-- that is the external resource dictionary file -->
<ResourceDictionary Source ="CircleII.xaml" />
</Window.Resources>
<Grid>
<Button>
<Image Width="200" Source="{StaticResource Circle}">
</Image>
</Button>
</Grid>
......

That is which i need. cool. now i have the problem with the GrayScale for a
Image. How can i set or use the GrayScale for my Image without
"FormatConvertedBitmap"? Is it possible? I think i have no chance to set the
Source property from "FormatConvertedBitmap" to my Circle resource. Or is it
possible to set the Source property to my Circle resource?

My goal is it, that the Image is disabled.

Thank you for all help
