转BitmapImage

{encoder.Save(memoryStream);memoryStream.Seek(0, SeekOrigin.Begin);bitmapImage.BeginInit();bitmapImage.CacheOption = BitmapCacheOption.OnLoad;bitmapImage.StreamSource = memoryStream;bitmapImage.EndInit();
}
转System.Drawing.Image
MemoryStream memoryStream = new MemoryStream(); encoder.Save(memoryStream); System.Drawing.Image img = System.Drawing.Image.FromStream(memoryStream);
