I'm running Debian 12.8.
I have a 100+ page PDF document.
I wish to extract 2 of those pages, each to their own PDF file for later editing.

I'm focusing on poppler-utils as it appears to offer tools for current
and future goals.

Doing "pdftotext -layout -f 116 -l 116 TFP2021.pdf jul24-a.txt" comes
very close to what I want.

Having been surrounded by TECO-buffs in the 70's, comparing the output
of "pdftotext -f 116 -l 116 TFP2021.pdf jul24-b.txt" to the above
suggests an approach to resolving.

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?

TIA

*A postscript

I had originally composed this message before discovering "pdfseparate"
had created output files that that appear to be what I intended.

I'm still interested in the meaning of the error messages as it may hint
as why ""pdftotext" wasn't *exactly* what I hoped for.

I think the PDF is malformed, although not necessarily fatally so.

Why not use pdfseparate to extract the two pages you want, and then use pdftotext on each of the two pages?

Interesting read as is manpage for mutool {just installed}.

I have no control of the source document[1] as it a USDA publication.
Is there an independent site, which when given a URL will evaluate
structural correctness [esp one whose evaluation would be worth
reporting to USDA]?

That's what I'd done.

Just tried mutool for the first time.
Got an interesting permutation of warnings, errors, and post-processing
of the result(s) ;}!
Is there a good newbie intro to mutool somewhere?
TIA

Yes. If I open the pdf in Chrome, I can go to page 116 and print it to
pdf without trouble. Similarly with xpdf. However okular uses the
document's page numbr instead on the numer as the page location. (Thus
you have to go to page 106 in okular to get to the Market Basket page).

If I try pdfseparate, I also get that whole list of

Missing 'endstream' or incorrect stream length

error messages, but the correct single page is created (Ie, those error messages
appear to be warnings, and can be ignored.) And they do not appear to
slow things down (it takes much less than a second to create that output
page).
