    TIFF: Как преобразовать TIFF файл в BigTIFF файл?
    В этом разделе
    Вот C#/VB.NET код, который демонстрирует, как преобразовать TIFF файл в BigTIFF файл:
    /// <summary>
    /// Converts standard TIFF file to a big TIFF file (TIFF file which can be bigger than 4Gb).
    /// </summary>
    public void ConvertTiffToBigTiff(string tiffFileName, string bigTiffFileName)
    {
        // open standard TIFF file
        using (Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFile tiffFile = 
            new Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFile(tiffFileName))
        {
            // create big TiffFile
            using (Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFile bigTiffFile = 
                new Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFile(
                    Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFileFormat.LittleEndian, 
                    Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffFileVersion.BigTIFF))
            {
                // for each page of standard TIFF file
                foreach (Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffPage page in tiffFile.Pages)
                    // add page to a big TIFF file
                    bigTiffFile.Pages.Add(page);
    
                // save big TIFF file to a disk
                bigTiffFile.Save(bigTiffFileName);
            }
        }
    }
