Here we will see that how to rotate an image to a certain angle around a central point in WPF using XAML.

Rotate Transform

Rotate Transform is used for the process of rotating an element to a certain angle around a central point. The below example shows image rotating according to a angle.

Example

Creating a Image control and three Button control on the window form.

XAML code

<Window x:Class="MainWindow"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="MainWindow" Height="350" Width="525">

   <Grid>

        <Button Content="LeftRotate" Height="23" HorizontalAlignment="Left" Margin="386,12,0,0" Name="Button1" VerticalAlignment="Top" Width="75" />

        <Image Height="150" HorizontalAlignment="Left" Margin="134,40,0,0" Name="Image1" Stretch="Fill" VerticalAlignment="Top" Width="200" Source="/WpfApplication76;component/Images/image1.jpg.gif" />

        <Button Content="RightRotate" Height="23" HorizontalAlignment="Left" Margin="386,49,0,0" Name="Button2" VerticalAlignment="Top" Width="75" />

        <Button Content="Same" Height="23" HorizontalAlignment="Right" Margin="0,87,42,0" Name="Button3" VerticalAlignment="Top" Width="75" />

    </Grid>

</Window>

 

The window form looks like this.

Now double click on the each Button control and add the following code.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click

        Dim rotateTransform1 As New RotateTransform()

        rotateTransform1.Angle = 30

        Image1.RenderTransform = rotateTransform1

    End Sub

 

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button2.Click

        Dim rotateTransform1 As New RotateTransform()

        rotateTransform1.Angle = 60

        Image1.RenderTransform = rotateTransform1

    End Sub

 

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button3.Click

        Dim rotateTransform1 As New RotateTransform()

        Image1.RenderTransform = rotateTransform1

    End Sub

 

Now run the application.
