Rotate taken photo in Windows Store Universal App

Question

I have created a Universal App which has a capability of taking photos which I do like this:

var imgFormat = ImageEncodingProperties.CreateJpeg();

var file = await ApplicationData.Current.LocalFolder.CreateFileAsync(
                "photo.jpg",
                CreationCollisionOption.GenerateUniqueName);

await _captureManager.CapturePhotoToStorageFileAsync(imgFormat, file);

var photo = new  BitmapImage(new Uri(file.Path));

When I then open the photo I see it rotated by 90 degrees (only images that are taken with the phone in portrate mode!). How can I rotate it back so that it's all displayed correctly?

Answer 1

With BitmapTransform you can do some simple transformations to bitmap images. Here is a sample of how a bitmap is rotated by 90 degrees.
