here I have an image (I want to display it as an icon in my list).
and I have to change its color when it's selected.
I tried this solution before:
https://stackoverflow.com/a/42794551/14564778
With this codes:
<Grid Margin="5,0,0,0">
<Image Height="25" Width="25" Source="{Binding ItemImageSource}" RenderOptions.BitmapScalingMode="Fant"/>
<Rectangle Height="25" Width="25" Fill="{StaticResource orangePink}" RenderOptions.BitmapScalingMode="Fant">
<Rectangle.OpacityMask>
<ImageBrush ImageSource="{Binding ItemImageSource}"/>
</Rectangle.OpacityMask>
</Rectangle>
</Grid>
The problem I got is the shape of the image is not consistent when I apply the new color
Note that the images that I use are high resolution images.
so, If anyone can help me with codes or third-party library or another way.
I will be happy for this.
thx...

Hi I'm struggling with rotation in XAML. I found a solution that LayoutTransform should solve this issue, but on Windows Universal Plattform this option isn't available!
This is my Code:
<StackPanel Orientation="Horizontal" VerticalAlignment="Center"
HorizontalAlignment="Center">
<Rectangle Fill="Red" Height="100" Width="100" />
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center"
Text="long long long long long long long long text"
RenderTransformOrigin="0.5,0.5" >
<TextBlock.RenderTransform>
<CompositeTransform Rotation="90"/>
</TextBlock.RenderTransform>
</TextBlock>
<Rectangle Fill="Green" Height="100" Width="100" />
</StackPanel>
But as you can see there are an huge margin between the colored boxes and the textblock as you can see here:
So my first guess was to add an Width="30" property to the textblock, but this isn't working as you can see here (not only the offset is the problem, but the cropping is the problem):
Any suggestions?
Try the LayoutTransform control of the WinRTXamlToolkit. Following links should help.

Currently i am designing WPF application using MahApps.Metro style UI.
Tile control which provided by MahApps can not showing icon in center of tile
I saw example in MahApps website where it could show image as tile background, but I couldn't figure out how to show icon instead of image (icon such as IE logo, people logo, maps logo, etc)
I appreciated if someone can show me how to do this
Thank you
i figure it out
use icons.xaml as resource, and add rectangle control inside tile, here is the example on how to show character inside tile control
<Controls:Tile x:Name="mahTileExit" Background="Green" Foreground="Yellow" Title="Exit" Width="100" Height="100" TiltFactor ="4" Margin="936,404,0,0" VerticalAlignment="Top" HorizontalAlignment="Left">
<Rectangle Fill="White" Height="45" Width="45">
<Rectangle.OpacityMask>
<VisualBrush Visual="{StaticResource appbar_door_leave}" Stretch="Fill" />
</Rectangle.OpacityMask>
</Rectangle>
</Controls:Tile>
thank you if anyone notice about this, hope can help to contribute
You can use FontAwesome.Wpf which has more icons and requires less code.
<Controls:Tile Width="300" Height="150" Grid.Column="0" Grid.Row="1" Title="Hello!">
<Grid Width="50" Height="50">
<fa:ImageAwesome Icon="Flag" Foreground="#FFFFFF"/>
</Grid>
</Controls:Tile>
Don't forget to call the namespace
xmlns:fa="http://schemas.fontawesome.io/icons/"
I am trying to rotate an image and want to use a storyboard as in the next phases i need to add multiple animations running to time.
my code is inside a click event of a button as follows:
//start the animation
DoubleAnimation animationRotation = new DoubleAnimation();
animationRotation.From = -17;
animationRotation.To = 17;
animationRotation.Duration = new Duration(TimeSpan.FromMilliseconds(NumericDisplay.Milliseconds));
animationRotation.RepeatBehavior = RepeatBehavior.Forever;
animationRotation.AccelerationRatio = 0.3;
animationRotation.DecelerationRatio = 0.3;
animationRotation.AutoReverse = true;
Storyboard storyboard = new Storyboard();
Storyboard.SetTarget(animationRotation, Arm);
Storyboard.SetTargetProperty(animationRotation,
new PropertyPath("(UIElement.RenderTransform).(TransformGroup.Children)[0].(RotateTransform.Angle)"));
storyboard.Children.Add(animationRotation);
// Add the storyboard to the tracking collection.
//this.Stostoryboards.Add(bomb, storyboard);
// Configure and start the storyboard.
this.BeginStoryboard(storyboard);
the code compiles without warning yet the click event does not start the animation,
EDIT
One of the proposed answers asked me to check the XAML included a definition for rotatetransform ... the XAML below is what I am using

what am I doing wrong?
The code you've posted seems to be ok, however, the path refers to an existing element, so make sure you've included appropriate nodes in xaml, where Arm control is defined.
Let's say Arm is a Rectangle control. Your xaml should then look more or less like this:
...
<Rectangle x:Name="Arm" Fill="Aqua" Width="100" Height="100" Canvas.Left="100" Canvas.Top="100">
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform />
</TransformGroup>
</Rectangle.RenderTransform>
</Rectangle>
...
Arm can be another type of control, but the important thing is that RenderTransform, TransformGroup and RotateTransform nodes are defined, so animation has some existing elements to change as specified in the PropertyPath in your code.
after much messing around with new projects and much simplified code I asked the question slightly differently in another thread and someone posted working code.
on investigation that reason my animation was not working was that I had provided a duration to the animation but not the storyboard itself !! doh.

How do I create a rotate animation on an image object using c# code only (inside a WPF window)
Lucas, thanks to you for your patience and assistance on this question.

I have a StackPanel containing five images and I want to put a black border around each image.
The XAML I have at the moment is:
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top" />
I thought I would be just able to put a one-unit margin or padding on the image and set a background color to 000000 but Padding and Background are both invalid for images.
What is an easy way to do this in XAML? Do I really have to put each image inside another control to get a border around it or is there some other trickery I can use?
Simply wrap the Image in a Border control
<Border BorderThickness="1">
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top" />
</Border>
You could also provide a style you apply to images that does this if you don't want to do it around every image
Final solution from answer and comments added by Pax:
<Border BorderThickness="1"
BorderBrush="#FF000000"
VerticalAlignment="Top">
<Image Name="imgPic1"
Width="100"
Height="75"
Stretch="Fill"
VerticalAlignment="Top"/>
</Border>
The accepted answer will not work because of the problem described here
https://wpf.2000things.com/2011/04/17/279-adding-a-border-around-an-image-control/
I solved it this way.
<Viewbox>
<Border BorderThickness="3" BorderBrush="Red">
<Image Stretch="None" ></Image>
</Border>
</Viewbox>
I just stumbled upon this post and the other answer did not work right. Maybe because I now use framework 4 and this post is old?
In any case - if someone will see this by chance in the future - here is my answer:
<Border Name="brdSiteLogo"
BorderThickness="2"
BorderBrush="#FF000000"
VerticalAlignment="Top"
HorizontalAlignment="Left"
Margin="12,112,0,0"
Height="128"
Width="128">
<Image Name="imgSiteLogo"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Stretch="Fill"/>
</Border>
The border thickness and brush are important (if you wont choose a color - you will not see the border!!!)
Also, the border should be aligned on your window. The image is "inside" the border, so you can use margins or just stretch it like I did.
In my project I want to display a small logo on the side of a custom control. Since I have no canvas I thought maybe a Visual Brush would be a good Idea to place the logo in the background.
<VisualBrush>
<VisualBrush.Visual>
<Rectangle Width="200" Height="200" Fill="Red" />
</VisualBrush.Visual>
</VisualBrush>
But the Rectangle I am using right now is not 200x200. It takes the complete available space. Thats not what I want. I also tried a Viewbox and set the stretch property but the result is the same because in the end I don't need a simple Rectangle but a canvas with many path objects as children. A Viewbox supports only one child.
This there any way to get around this problem?
You need to set TileMode, Stretch, AlignmentX and AlignmentY properties on your VisualBrush:
<VisualBrush TileMode="None" Stretch="None" AlignmentX="Left" AlignmentY="Top">
<VisualBrush.Visual>
<Rectangle Height="200" Width="200" Fill="Red"></Rectangle>
</VisualBrush.Visual>
</VisualBrush>
Add Grid and this Set Vertical alligment to Top and Horizontal alignment to Right
Sample code
<VisualBrush x:Key="myVisual">
<VisualBrush.Visual>
<Grid>
<Rectangle Height="200" Width="200" Fill="Red" HorizontalAlignment="Right" VerticalAlignment="Top" ></Rectangle>
</Grid>
</VisualBrush.Visual>
</VisualBrush>
For me, I set the following attribute on the VisualBrush, and the VisualBrush now looks exactly like a MediaElement:
Stretch="Uniform"
