PDF SaveAsTIFF Not working

Aspose.PDF Product Family

I have a PDF file that works fine in reader, I can send it as an email attachment, save it to disk reads fine. When I try to save it as TIFF it bombs.

Error: Object reference not set to an instance of an object.

Here is the code used:

public static bool PDFtoTIFList(string rmolid, string inPDF, Dictionary<string, string> Settings) {
  int fid = 0;
  var retData = new List<string>();
  Aspose.Imaging.Cache.CacheType = CacheType.CacheOnDiskOnly;
  Aspose.Imaging.Cache.CacheFolder = Settings["RMOLTemp"];
  try {
    var outTIF = string.Format("{0}{1}_{2:D2}.tif", Settings["RMOLTemp"], rmolid, ++fid);
    using (Aspose.Pdf.Facades.PdfConverter pdfC = new Aspose.Pdf.Facades.PdfConverter()) {
      Resolution res = new Resolution(300, 300);
      pdfC.Resolution = res;
      pdfC.BindPdf(inPDF);
      TiffSettings ts = new TiffSettings();
      ts.Depth = ColorDepth.Format1bpp;
      ts.Compression = CompressionType.CCITT4;
      pdfC.SaveAsTIFF(outTIF, Aspose.Pdf.PageSize.A4, ts);
      //pdfC.SaveAsTIFF(outTIF);
    }
  } catch (Exception ex) {
    ex = ex;
  }
  return true;
}

}

Hello,

My supervisor asked me to clarify. When you pay the yearly subscription is there no “Paid Support” included? We have had 2 issues in the 3 years we have been using and both issues turned out to be real issues that only helps Aspose to fix.

Thanks,
Taylor
