creating Bitmap from multi-page TIFF

I have a multipage TIFF I create on the fly, which needs to be broken up into two page TIFFs and serialized to a MemoryStream. In addition, I am converting the compression from LZW to Group IV. I am using .NET 3.5 with LeadTools version 17.0.

Perhaps I'm making this more difficult than it should be, but I'm not sure the best way to do it. Here's whats I currently have:

                RasterCodecs codecs = new RasterCodecs();
                CodecsImageInfo info = codecs.GetInformation( file, true );
                RasterImage image = codecs.Load( file, 0, CodecsLoadByteOrder.RgbOrGray, currentPage, currentPage + (detail.Pages - 1) );
               Image newImage = RasterImageConverter.ConvertToImage( image, ConvertToImageOptions.None );
               MemoryStream memStream = new MemoryStream();
                  newImage.Save( memStream, System.Drawing.Imaging.ImageFormat.Tiff );

               ImageCodecInfo encoderInfo = GetEncoderInfo(  );

                  EncoderParameters encoderParams = new EncoderParameters( 2 );
                  EncoderParameter parameter = new EncoderParameter( System.Drawing.Imaging.Encoder.Compression, (long)EncoderValue.CompressionCCITT4 ); //change compression
                  encoderParams.Param[0] = parameter;
                  EncoderParameter param2 = new EncoderParameter( System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.MultiFrame );
                  encoderParams.Param[1] = param2;
                  newImage.Save(memStream, encoderInfo , encoderParams); //save first page to stream

                  if (detail.Pages == 2)
                  {
                     encoderParams.Param[1] = new EncoderParameter( System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.FrameDimensionPage );
                     image.Page = 2; //move image to the next page
                     newImage.SaveAdd( RasterImageConverter.ConvertToImage( image, ConvertToImageOptions.None ), encoderParams );

                     encoderParams.Param[1] = new EncoderParameter( System.Drawing.Imaging.Encoder.SaveFlag, (long)EncoderValue.Flush );
                     newImage.SaveAdd( encoderParams );

                  }

All you need is:
1. Load the image using RasterCodecs.Load(
   string fileName,
   int bitsPerPixel,
   CodecsLoadByteOrder order,
   int firstPage,
   int lastPage)

2. Save the image using RasterCodecs.Save(
   RasterImage image,
   string fileName,
   RasterImageFormat.CcittGroup4,
   1,
   int firstPage,
   int lastPage,
   int firstSavePageNumber,
   CodecsSavePageMode pageMode)

You can either use the CodecsSavePageMode.Overwrite to create new file (Overwrite the entire file), or CodecsSavePageMode.Append Append the page to the end of the file.

You don't need to worry about any encoder objects.
