public Rotation Rotation { get; set; }
/** @property */
public Rotation get_Rotation ()

/** @property */
public void set_Rotation (Rotation value)

public function get Rotation () : Rotation

public function set Rotation (value : Rotation)

<object Rotation="Rotation" .../>

Property Value

The rotation that is used for the BitmapImage. The default is Rotate0.

Identifier Field

RotationProperty

Metadata Flags

None

Rotation is performed after scaling. This means that an image that has a Rotation of Rotate90, a DecodePixelWidth of 10, and DecodePixelHeight of 5 will result in an image that has a width of 5 and a height of 10.

The following code example demonstrates how to rotate an image by using Extensible Application Markup Language (XAML) and code.

<Image Width="150" Margin="5" Grid.Column="0" Grid.Row="1">
  <Image.Source>
    <TransformedBitmap Source="/sampleImages/watermelon.jpg" >
      <TransformedBitmap.Transform>
        <RotateTransform Angle="90"/>
      </TransformedBitmap.Transform>
    </TransformedBitmap>
  </Image.Source>
</Image>

<Image Width="150" Margin="5" Grid.Column="0" Grid.Row="1">
  <Image.Source>
    <TransformedBitmap Source="/sampleImages/watermelon.jpg" >
      <TransformedBitmap.Transform>
        <RotateTransform Angle="90"/>
      </TransformedBitmap.Transform>
    </TransformedBitmap>
  </Image.Source>
</Image>

// Create Image element.
Image rotated90 = new Image();
rotated90.Width = 150;

// Create the TransformedBitmap to use as the Image source.
TransformedBitmap tb = new TransformedBitmap();

// Create the source to use as the tb source.
BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.UriSource = new Uri(@"sampleImages/watermelon.jpg", UriKind.RelativeOrAbsolute);
bi.EndInit();

// Properties must be set between BeginInit and EndInit calls.
tb.BeginInit();
tb.Source = bi;
// Set image rotation.
RotateTransform transform = new RotateTransform(90);
tb.Transform = transform;
tb.EndInit();
// Set the Image source.
rotated90.Source = tb;
