SaveAsTIFF move annotation object on output

Aspose.PDF Product Family
1

Hello,

We built an application to process PDF files and convert them to TIFF for storage in our Document Management System. The PDF files come from multiple sources, and we encountered an issue where the PDF would not convert to a TIFF correctly. On some occasions, if the PDF contains annotations, the annotation object will appear in a different location on the TIFF file.

This has been tested using Aspose.Pdf.Kit.dll, Version 5.8.0.0, as well as the latest version 6.0.0.0.

Here’s a sample code we used for the conversion:

private void ConvertPdfToTiff(string sourceFileNameIncludingPath, string destinationFileNameIncludingPath)
{
    string compressionTypeName = Enum.GetName(typeof(TiffCompressionType), tiffSettings.CompressionType);
    compressionTypeName = compressionTypeName.Remove(0, "Compression".Length);

    CompressionType compressionType = (CompressionType)Enum.Parse(typeof(CompressionType), compressionTypeName, true);

    PdfConverter pdfConverter = new PdfConverter();
    try
    {
        pdfConverter.BindPdf(sourceFileNameIncludingPath);
        pdfConverter.Resolution = tiffSettings.Resolution;
        pdfConverter.SaveAsTIFF(destinationFileNameIncludingPath, tiffSettings.Resolution, tiffSettings.Resolution, compressionType);
    }
    finally
    {
        pdfConverter.Close();
    }
}

I have attached two files to this thread:

  1. Sample.pdf: the source PDF
  2. Sample.tiff: the output of the SaveAsTIFF call

You can see in these 2 files an illustration of the issue we’re facing.

Please advise.

Thanks,
Jm

Hi Jm,

I have tested the scenario and have managed to reproduce the same problem that annotations are being displayed over different location when PDF file is converted into TIFF format. For the sake of correction, I have logged this problem as PDFNEWNET-31275 in our issue tracking system. We will further look into the details of this problem and will keep you updated on the status of correction. We are sorry for your inconvenience.
