About Rotation image in any Angle

Question

Hello,

 

I am dealing with images in my project. I am giving some angle and my Image should rotate in that angle. But It only rotate in multiples of 90 as I am using TransformedBitmap.

 

So please help me for rotating image in any angle and after rotation new image will be saved.

 

thanks in advanced. 

 

Source code is:-

 

Image image = new Image();

BitmapImage bitmapImage = new BitmapImage();

bitmapImage.BeginInit();

bitmapImage.CacheOption = BitmapCacheOption.OnLoad;

bitmapImage.UriSource = new Uri(_DataSource.BackgroundImageFullPath);

bitmapImage.EndInit();

image.Source = bitmapImage;

BitmapSource img = (BitmapSource)(image.Source);

//rotate tif and save

CachedBitmap cache = new CachedBitmap(img, BitmapCreateOptions.None, BitmapCacheOption.OnLoad);

TransformedBitmap tb = new TransformedBitmap(cache, new RotateTransform(imgAngle));

TiffBitmapEncoder encoder = new TiffBitmapEncoder();

encoder.Frames.Add(BitmapFrame.Create(tb));

using (FileStream file = File.OpenWrite(_DataSource.BackgroundImageFullPath))

{

encoder.Save(file);

}
