Syntax
Visual Basic (Declaration)
Public Property Rotation As Rotation
Dim instance As BitmapImage
Dim value As Rotation
value = instance.Rotation
instance.Rotation = value
public Rotation Rotation { get; set; }
public:
property Rotation Rotation {
Rotation get ();
void set (Rotation value);
}
public function get Rotation () : Rotation
public function set Rotation (value : Rotation)
<object Rotation="Rotation" .../>
Dependency Property Information
Remarks
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.
Examples
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>
' 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
// 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;
