Analyzing PDF document objects - Could not able to uncompress the pdf text stream

Hi,

 

I am working on the trial version of ABBYY FineReader. I usually try to uncompress pdf objects using QPDF to inspect objects/dictionaries. I never had issues earlier while inspecting pdf objects.

 

But now when I try to convert pdf document to tagged-pdf/non-tagged (just running through ABBYY finereader), I could not able to uncompress the text stream using qpdf. I think this may be issue with the ABBYY want to check with your team.

 

I am curious to know if we create a pdf document with ABBYY it can’t be uncompressed to see the text content?

 

Attached file –

1.        taggedpdf-with paragraphs-t-qpdf.pdf– I manually converted from word to pdf and if you edit this pdf in text editor I can able to see the content

2.       This is the scenario with the ABBYY – I tried to run this  document through ABBYY to see if I still can able to edit the objects

a.       Converted document from ‘taggedpdf-with paragraphs-t.pdf’ to ‘taggedpdf-with paragraphs-t_ABBYY.pdf’

b.       Then with qpdf I tryied to convert to see the pdf objects but I could not able to view the content on this file ‘taggedpdf-with paragraphs-t_ABBYY-qpdf.pdf’

 

 

 

Here is the additional code I added to the existing sample code.

 

FREngine.PDFExportParams pdfParams = engineLoader.Engine.CreatePDFExportParams();

pdfParams.PDFFeatures.WriteTaggedPDFMode = FREngine.WriteTaggedPDFModeEnum.WTM_Write;

document.Export(System.IO.Path.Combine(FreConfig.GetSamplesFolder(), txtFileLocation),

 

                             FREngine.FileExportFormatEnum.FEF_PDF, pdfParams);
