full Black/blank Pages on colored pages

[Jorge Lucio]

With the following code, I create a PDF document from a tif file, if necessary, but when I save the file and some of its pages have color like ink, image or something, the pages turn out completely black. Am I doing something wrong?

 public PdfLoadedDocument GetPDF(FileInfo FOrigen, String tempfile = "", bool EliminaORigen = false)

        {

            PdfLoadedDocument _pdfloadedDocument;

            try

            {

                if(FOrigen.Extension.ToLower() == ".pdf")

                    System.IO.File.Copy(FOrigen.FullName, tempfile);

                else

                {

                    PdfDocument _pdfDocument = new PdfDocument();

                    _pdfDocument.PageSettings.Margins.All = 0;

                    //Get the image stream and draw frame by frame

                    using (var tiffImage = new PdfBitmap(FOrigen.FullName))

                    {

                        int frameCount = tiffImage.FrameCount;

                        for (int i = 0; i < frameCount; i++)

                        {

                            //Add pages to the document

                            var page = _pdfDocument.Pages.Add();

                            //Getting page size to fit the image within the page

                            SizeF pageSize = page.GetClientSize();

                            //Selecting frame in TIFF

                            tiffImage.ActiveFrame = i;

                            //Draw TIFF frame

                            page.Graphics.DrawImage(tiffImage, 0, 0, pageSize.Width, pageSize.Height);

                        }

                        tiffImage.Dispose();

                    }

                    _pdfDocument.Compression = PdfCompressionLevel.Best;

                    _pdfDocument.Save(tempfile);

                    _pdfDocument.Close();

                }

                _pdfloadedDocument = new PdfLoadedDocument(tempfile);

                if (EliminaORigen && File.Exists(FOrigen.FullName))

                    File.Delete(FOrigen.FullName);

                return _pdfloadedDocument;

            }

            catch(Exception)

            {

                if (EliminaORigen && File.Exists(FOrigen.FullName))

                    File.Delete(FOrigen.FullName);

                throw;

            }

        }

-----------------------------------

private static void SaveOpenpdf(PdfLoadedDocument _pdfloadedDocument, String temppdf)

        {

            _pdfloadedDocument.Compression = PdfCompressionLevel.Best;

            PdfCompressionOptions options = new PdfCompressionOptions

            {

                OptimizeFont = true,

                OptimizePageContents = true,

                CompressImages = true,

                ImageQuality = 10

            };

            _pdfloadedDocument.CompressionOptions = options;

            _pdfloadedDocument.Save(temppdf);

            _pdfloadedDocument?.Close();

        }
