Rotate bitmapImage in windows store app

Question

trying to rotate a bitmapImage 90 degrees but have been unable so far.

this: http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapimage.rotation(v=vs.110).aspx#feedback

doesn't actually work. TransformedBitmap type does not exist and and BitmapImage has no .beginInit() and .EndInit() methods

I already have added

using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Media.Imaging;

have MS forgot to update their documentation, am I doing something wrong or is this actually not meant for Windows 8?

http://msdn.microsoft.com/en-us/library/windows/apps/windows.graphics.imaging.bitmaptransform.aspx I also found this but were unable to find an example of using it.

this as suggested by Mihai Hantea ended up doing the trick. Turns out I was missing an Await command on a .FlushAsync(). After addding the await it suddenly came together and worked brilliantly.

The TransformedBitmap type does exist. But you have to add a reference to you project to PresentationCore.dll

Then follow this example: http://msdn.microsoft.com/en-us/library/aa970271(v=vs.110).aspx

(Stolen from the link)

BitmapImage myBitmapImage = new BitmapImage();

myBitmapImage.BeginInit();
myBitmapImage.UriSource = new Uri(@"C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water Lilies.jpg");

myBitmapImage.DecodePixelWidth = 200;
myBitmapImage.EndInit();

TransformedBitmap myRotatedBitmapSource = new TransformedBitmap();

myRotatedBitmapSource.BeginInit();

myRotatedBitmapSource.Source = myBitmapImage;

myRotatedBitmapSource.Transform = new RotateTransform(90);
myRotatedBitmapSource.EndInit()

Maybe this can help in your situation:

Code-Behind:

var image = new Image
                    { 
                        Height = 50,
                        Width = 50,
                        RenderTransform = new RotateTransform() 
                        { 
                        Angle = 90, 
                        CenterX = 25, //The prop name maybe mistyped 
                        CenterY =25 //The prop name maybe mistyped 
                        },
                        Source = new BitmapImage(new Uri("MyImageSoruce"))
                    };

MainGrid.Children.Add(image);
