'Declaration
Public Property Rotation As Rotation
'Usage
Dim instance As BitmapImage
Dim value As Rotation

value = instance.Rotation

instance.Rotation = value
/** @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.
Dim rotated90 As New Image()
rotated90.Width = 150

' Create the TransformedBitmap to use as the Image source.
Dim tb As New TransformedBitmap()

' Create the source to use as the tb source.
Dim bi As 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.
Dim transform As New RotateTransform(90)
tb.Transform = transform
tb.EndInit()
' Set the Image source.
rotated90.Source = tb
