How to: Rotate an Image
This example shows how to rotate an image 90 degrees by using a Rotation property of a BitmapImage.
Example
<Image Width="150" Margin="5" Grid.Column="0" Grid.Row="1">
<Image.Source>
<BitmapImage UriSource="/sampleImages/watermelon.jpg" Rotation="Rotate90" />
</Image.Source>
</Image>
//Create Image element
Image rotated270 = new Image();
rotated270.Width = 150;
//Create source
BitmapImage bi = new BitmapImage();
//BitmapImage properties must be in a BeginInit/EndInit block
bi.BeginInit();
bi.UriSource = new Uri(@"pack://application:,,/sampleImages/watermelon.jpg");
//Set image rotation
bi.Rotation = Rotation.Rotate270;
bi.EndInit();
//set image source
rotated270.Source = bi;
