I don't understand the paragraph above, and especially what the mention of TECO infers? > It involves being able to edit a *SINGLE* rather than all 100+ > companion pages. > > I tried "pdfseparate -f 116 -l 116 TFP2021.pdf dianostic.pdf" and got > > Syntax Error (3868069): Missing 'endstream' or incorrect stream > > length Syntax Error (3557294): Missing 'endstream' or incorrect > > stream length [multiple repetitions of those 2 lines > > Syntax Error (3556857): Bad FCHECK in flate stream > > Syntax Error (3868069): Missing 'endstream' or incorrect stream > > length Syntax Error (3866517): Bad FCHECK in flate stream > > How/where do I find interpretation of those? Good question that I'm not able to help answer, I'm afraid. But looking at the messages suggests that you PDF file may not be perfectly formed, so I suggest trying to validate it. There seems to be no shortage of PDF validators online! Another approach might be to try using one of the other tools that were suggested rather than poppler. They may produce clearer error messages.
