About Rotation image in any Angle

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);

}

You could use a professional toolkit like LEADTOOLS which has a wide range of image processing classes and methods, including rotation of images with high resolution.
For example, to load an image, rotate 45 degrees with bicubic interpolation and white fill color, then save back, the code will look like this:
RasterCodecs codecs = new RasterCodecs();
RasterImage image = codecs.Load("inputimage.tif");
float rotationAngle = 45; //degrees
RotateCommand command = new RotateCommand(rotationAngle * 100, RotateCommandFlags.Bicubic, new RasterColor(255, 255, 255));
command.Run(image);
image = codecs.Save(image, "outputimage.tif", RasterImageFormat.TifLzw, 24);

Try like this, this may help, thanks in advance

// Define a BitmapImage.
Image myImage = new Image();
BitmapImage bi = new BitmapImage();
// Begin initialization.
bi.BeginInit();
// Set properties.
bi.CacheOption = BitmapCacheOption.OnDemand;
bi.CreateOptions = BitmapCreateOptions.DelayCreation;
bi.DecodePixelHeight = 125;
bi.DecodePixelWidth = 125;
bi.Rotation = Rotation.Rotate90;
MessageBox.Show(bi.IsDownloading.ToString());
bi.UriSource = new Uri("smiley.png", UriKind.Relative);
// End initialization.
bi.EndInit();
myImage.Source = bi;
myImage.Stretch = Stretch.None;
myImage.Margin = new Thickness(5);
