Getting “insufficient memory to continue the execution of the program.” while saving the tiff images after rotation.

I have 10MB+ Tiff files having 50 pages, and I want to perform rotation of all the pages by 90 degree at one click only, but after performing the rotation operations for each frames in foreach loop and when it comes to the

Save(Encoder encoder)

then here,

encoder.Save(temporaryStream); // this line is giving exception.

Here, If I am doing rotation for 6 pages tiff images that time I am not getting any exception but when doing the same operation for 50 pages that time I am getting exception.

Type :	System.OutOfMemoryException
Message :	Insufficient memory to continue the execution of the program.
HResult :	0x8007000E
Source :	PresentationCore
   at System.Windows.Media.Imaging.BitmapEncoder.SaveFrame(SafeMILHandle frameEncodeHandle, SafeMILHandle encoderOptions, BitmapFrame frame)
   at System.Windows.Media.Imaging.BitmapEncoder.Save(Stream stream)

Am I wrong here while saving the images after rotation?

Any help is appreciated.

What I have tried:

RotateImagePages(IEnumerable<int> pageNumbers, Degrees degree) //here, pageNumbers is total number of pages i.e 50,degree= 90.

code snippet:

private void RotateImagePages(IEnumerable<int> pageNumbers, Degrees degree)
  {
     // create the encoder
     BitmapEncoder encoder = BitmapEncoder.Create(Decoder.CodecInfo.ContainerFormat);

     // copy the destination frames
     foreach (BitmapFrame frame in Decoder.Frames)
        encoder.Frames.Add(frame);

     double angleOfRotation = (double)degree;

		foreach (var pageNumber in pageNumbers)
         {
            BitmapFrame oldFrame = encoder.Frames[pageNumber - 1];

            // Create the TransformedBitmap to use as the Image source.
            TransformedBitmap tb = new TransformedBitmap();
            //BitmapImage bi = new BitmapImage();
            
            // Properties must be set between BeginInit and EndInit calls.
            tb.BeginInit();

            tb.Source = new CachedBitmap(oldFrame, BitmapCreateOptions.None, BitmapCacheOption.OnLoad);
            RotateTransform transform = new RotateTransform(angleOfRotation);
            tb.Transform = transform;

            tb.EndInit();

            encoder.Frames.RemoveAt(pageNumber - 1);
            encoder.Frames.Insert(pageNumber - 1, BitmapFrame.Create(tb));
         }
		 Save(encoder);
	}
private void Save(BitmapEncoder encoder)
	{
     // save to a temporary stream
     string tempFileName = Path.GetTempFileName();

     try
     {
        using (FileStream temporaryStream = new FileStream(tempFileName, FileMode.Open))
        {
           if (encoder.Frames.Count > 0)
              encoder.Save(temporaryStream);

           // write back out to permanent stream
           if (Stream.CanWrite && Stream.CanSeek)
              CopyStream(temporaryStream, Stream);
           else
              throw new UnauthorizedAccessException();
        }
     }
     finally
     {
        // Delete the temporary file
        File.Delete(tempFileName);
     }
  }
  protected static void CopyStream(Stream input, Stream output)
  {
     input.Seek(0, SeekOrigin.Begin);
     output.Seek(0, SeekOrigin.Begin);
     output.SetLength(0);

     byte[] buffer = new byte[4096];
     int read;

     while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
        output.Write(buffer, 0, read);

     output.Seek(0, SeekOrigin.Begin);
  }
