I tried to add the wrapped the <Image with <border
I added
<Border BorderThickness="1">
And
</Border>
Then tried to wrapped the <Image like this :
<Border BorderThickness="1">
<Image x:Name="Img" HorizontalAlignment="Left" Height="233" Margin="467,54,0,0" VerticalAlignment="Top" Width="272" RenderTransformOrigin="0.5,0.5">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform AngleY="0.704"/>
<RotateTransform/>
<TranslateTransform Y="0.614"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</Border>
But it does nothing when running the application.
In the designer on the main window I have a StackPanel and then on it the other controls also Image control.
I want to show the user that there is a Image control like pictureBox the problem is when running the program and the Image is still empty there is nothing that indicate that there is a Image control. That's why I want to draw a rectangle on the Image borders.
You need to pick a brush for your Border.
<Border BorderThickness="1" BorderBrush="Black">
<Image x:Name="Img" HorizontalAlignment="Left" Height="233" Margin="467,54,0,0" VerticalAlignment="Top" Width="272" RenderTransformOrigin="0.5,0.5">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform AngleY="0.704"/>
<RotateTransform/>
<TranslateTransform Y="0.614"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</Border>
Actually, the method you applied is very close, since the picture will be in a border, it would be more logical to resize the border instead of resizing the picture. If you make an application like below, it will work for you.
<Border BorderThickness="2"
BorderBrush="Black"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Height="128"
Width="128">
<Image HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Stretch="Fill"
Source="/Images/antenna.png"/>
</Border>
It will be enough to have something like this in your application.
<Border BorderThickness="3" BorderBrush="Red" Height="233" Width="272">
<Image x:Name="Img" HorizontalAlignment="Left" Margin="467,54,0,0" VerticalAlignment="Top" RenderTransformOrigin="0.5,0.5">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform AngleY="0.704"/>
<RotateTransform/>
<TranslateTransform Y="0.614"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</Border>

Im doing a image binding with a slider and the only thing that i want to do its move the Y axis down to up, but at this moment im moving the axis up to down. What can i do to invert the moving of the angle y?
This is the code:
<Image Margin="400,0,200,37" Source="/img/santa_claus.png" Stretch="Uniform" VerticalAlignment="Bottom" Width="200" Height="195">
<Image.RenderTransform>
<TranslateTransform Y="{Binding Value, ElementName=slider}" x:Name="transform"/>
</Image.RenderTransform>
</Image>
<Slider Minimum="1" Maximum="100" x:Name="slider" Height="40" RenderTransformOrigin="0.5,0.5" Margin="226,392,200,12" >
<Slider.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform AngleY="-0.584"/>
<RotateTransform/>
<TranslateTransform Y="-1.482"/>
</TransformGroup>
</Slider.RenderTransform>
</Slider>
I tryied diferent properties and changing the slider minimum to 100 and maximum to 1 but this nullifies the effect of the slider
You may invert the direction of the translation by two "mirroring" ScaleTransforms with ScaleY="-1".
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleY="-1"/>
<TranslateTransform Y="{Binding Value, ElementName=slider}"/>
<ScaleTransform ScaleY="-1"/>
</TransformGroup>
</Image.RenderTransform>
As a general note, do not use Margins for layout. Put the two elements in two rows of a Grid:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Image Grid.Row="0" Source="/img/santa_claus.png"
VerticalAlignment="Bottom" Stretch="Uniform" Width="200" Height="195">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleY="-1"/>
<TranslateTransform Y="{Binding Value, ElementName=slider}"/>
<ScaleTransform ScaleY="-1"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
<Slider Grid.Row="1" x:Name="slider"
Minimum="0" Maximum="100" Width="200" Margin="10"/>
</Grid>
So I have successfully implemented a button click with a custom background. Here is the xaml:
<Button
HorizontalAlignment="Left"
Grid.Row="0"
Grid.Column="0"
Command="{Binding PreferencesClickedCmd}"
>
<Path
Data="..."
Stretch="Uniform"
Fill="#FF070707"
Width="16"
Height="16"
Margin="0,0,0,0"
RenderTransformOrigin="0.5,0.5"
>
<Path.RenderTransform>
<TransformGroup>
<TransformGroup.Children>
<RotateTransform Angle="0" />
<ScaleTransform ScaleX="1" ScaleY="1" />
</TransformGroup.Children>
</TransformGroup>
</Path.RenderTransform>
</Path>
</Button>
Now, is there a way to implement a click command with MVVM on Path object itself. What I am looking for to have only an icon portion to be clickable (with no help of button object). With button, the entire generated background rectangle can be clicked in order to trigger an event for the Path.
If you want only the filled Path area to be clickable, this will work (just swap in your own Path, transform, etc. stuff):
<Button
Command="{Binding PreferencesClickedCmd}"
>
<Button.Content>
<Path Data="M 8,0 L 0,16 L 16,0 Z" Fill="SlateBlue" />
</Button.Content>
<Button.Template>
<ControlTemplate TargetType="Button">
<ContentPresenter />
</ControlTemplate>
</Button.Template>
</Button>
The entire visual presentation of the button is replaced by just the content alone, and the parts of the button that aren't filled by the path are not clickable because they're transparent.
If you want the whole thing to be clickable, just give the template a background that's not quite transparent:
<ControlTemplate TargetType="Button">
<Grid Background="#01ffffff">
<ContentPresenter />
</Grid>
</ControlTemplate>
This is the MVVM Way of Doing Things: Button provides a Click event, and Command property, and some visual stuff; if all you want is the Click event and the Command Property, don't roll your own click event; use those parts of the Button while discarding the visual stuff.
As per Brandley suggestion, here is how I managed to implement it with minimal coding changes. I set the button size to match icon size, set the background to transparent and border width to 0:
<Button HorizontalAlignment="Left" Grid.Row="0" Grid.Column="0" Margin="5,0,0,0" Width="30" Height="30" BorderThickness="0" Background="Transparent" Command="{Binding PreferencesClickedCmd}">
<Path Data="..." Stretch="Uniform" Fill="#FF070707" Width="16" Height="16" Margin="0,0,0,0" RenderTransformOrigin="0.5,0.5">
<Path.RenderTransform>
<TransformGroup>
<TransformGroup.Children>
<RotateTransform Angle="0" />
<ScaleTransform ScaleX="1" ScaleY="1" />
</TransformGroup.Children>
</TransformGroup>
</Path.RenderTransform>
</Path>
</Button>
I have the below code. I am trying to place the image directly to the right of the textblock within the border, but the image is almost touching the right side of the screen. How can I allign the image to the right of the textblock
<Border BorderBrush="#FFD6D4D4" BorderThickness="0,0,0,1" Grid.Column="0" Grid.Row="1"
Height="28" VerticalAlignment="Top" Background="#FFF7F7F7"
HorizontalAlignment="Stretch">
<DockPanel LastChildFill="False">
<TextBlock DockPanel.Dock="Left"
Style="{StaticResource HeaderTextBlockStyle}"
Text="Check new items"
VerticalAlignment="Center" Margin="2" />
<Image
DockPanel.Dock="Left"
VerticalAlignment="Center"
SnapsToDevicePixels="True"
UseLayoutRounding="True"
RenderOptions.BitmapScalingMode="HighQuality"
Source="/Media/pointer.png"
RenderTransformOrigin="0.95,4.046"
HorizontalAlignment="Center" Margin="0"
Height="25.306" Width="25.008>
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="49.57"/>
<TranslateTransform X="-39.746" Y="-21.185"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</DockPanel>
</Border>
Try using the Grid control and define two columns into it
<Border BorderBrush="#FFD6D4D4" BorderThickness="0,0,0,1" Grid.Column="0" Grid.Row="1"
Height="28" VerticalAlignment="Top" Background="#FFF7F7F7"
HorizontalAlignment="Stretch">
<Grid>
<Grid.ColumnDefinitions>
<Column Definition Width="*"/>
<Column Definition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Style="{StaticResource HeaderTextBlockStyle}"
Text="Check new items"
VerticalAlignment="Center" Margin="2" />
<Image
Grid.Column="1" VerticalAlignment="Center"
SnapsToDevicePixels="True"
UseLayoutRounding="True"
RenderOptions.BitmapScalingMode="HighQuality"
Source="/Media/pointer.png"
RenderTransformOrigin="0.95,4.046"
HorizontalAlignment="Center" Margin="0"
Height="25.306" Width="25.008>
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="49.57"/>
<TranslateTransform X="-39.746" Y="-21.185"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</Grid>
</Border>
Try using a StackPanel with Orientation set to horizontal instead of the dockpanel. That should put the image right next to the textblock.
if you still want to use the dock panel try setting the margin you want, on the image like margin="0,0,100,0"
how "Stretch" property of Image in WPF effects Transforms ?
I found that Stretch property of image effets the transforms applied to it.
When stretch=fill, then everything is fine but if stretch=uniform, the transforms are chaged.
I not getting why this happening. Plz explain.
CODE:
<Canvas Height="200" Width="200">
<Image Height="50" Width="50" RenderTransformOrigin="0.5,0.5" Source="Image.jpg" Stretch="Fill">
<Image.RenderTransform>
<TransformGroup>
<RotateTransform Angle="200" />
<TranslateTransform X="100" Y="100"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
<Rectangle Height="50" Width="50" RenderTransformOrigin="0.5,0.5" Fill="RoyalBlue" Opacity="0.5">
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="200" />
<TranslateTransform X="100" Y="100"/>
</TransformGroup>
</Image.RenderTransform>
</Rectangle>
</Canvas>
<Canvas Height="200" Width="200">
<Image Height="50" Width="50" RenderTransformOrigin="0.5,0.5" Source="Image.jpg" Stretch="Uniform">
<Image.RenderTransform>
<TransformGroup>
<RotateTransform Angle="200" />
<TranslateTransform X="100" Y="100"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
<Rectangle Height="50" Width="50" RenderTransformOrigin="0.5,0.5" Fill="RoyalBlue" Opacity="0.5">
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="200" />
<TranslateTransform X="100" Y="100"/>
</TransformGroup>
</Rectangle.RenderTransform>
</Rectangle>
</Canvas>
From my testing, it appears that this is just a bug in the way the Visual Studio designer previews this XAML.
I've taken your code and loaded it in both Visual Studio 2010 and in Expression Blend 4. In Visual Studio's designer, I see what you're talking about. In Expression Blend, the preview is correct.
Most importantly, when I run the application, it is rendered correctly. So I think you're ok. Just pretend like its not doing that or use Expression Blend when you have to work with this control.
In the following:
<Rectangle Height="60" HorizontalAlignment="Left" Margin="50,100,0,0" Name="rectangle2" Stroke="Black" VerticalAlignment="Top" Width="60" >
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="45" CenterX="30" CenterY="30"/>
</TransformGroup>
</Rectangle.RenderTransform>
To rotate the rectangle on its centre I have to set the CenterX and Y to half of the Rectangle's size. Is there a way to do that in markup?
Something like CenterX="{Binding Path=Width\2}" ?
You can set RenderTrasformOrigin property on the Rectangle itself:
<Rectangle Height="60" HorizontalAlignment="Left" Margin="50,100,0,0" Name="rectangle2"
Stroke="Black" VerticalAlignment="Top" Width="60"
RenderTrasformOrigin="0.5,0.5">
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="45" />
</TransformGroup>
</Rectangle.RenderTransform>
