Hi
I'm trying to figure out how to extract text from a PDF into an
accessibility tool
I've figured out how to walk the tagged structure returned by
GetStructTreeRoot, but stuck on how to get from an integer marked content
identifier (PDF 32000 14.7.2) to the actual text.
Looks like I

Only tested on Visual Studio - don't have a linux tool chain currently (but
looks correct after a quick scan of the GCC documentation).
PS Congratulations on getting the 0.8.0 release out - worked very smoothly
apart from this issue.

existing code).
The other alternative is to require apps to use the shared CRT, but that pulls
in other dependencies (e.g. installer merge modules and the broken SxS

Given that fixing this might uncover more problems, and it’s very close to
release day, I’d suggest keeping r1648 for the moment and I’ll submit a patch
after the release.
Does that sound ok?

Eliminating this will reduce memory requirements by 28%, but requires bigger
changes than just re-ordering members. I’ll look at that for next release.

The revised patch doesn’t compile because it uses:
+PODOFO_ERROR_INFO( ePdfError_ValueOutOfRange,
+"xref subsection's given entry numbers together too large" );
instead of
+PODOFO_RAISE_ERROR_INFO ( ePdfError_ValueOutOfRange,
+"xref
hes since the pObj ==
pObj->GetParent() case is probably the most common, but the depth check covers
other types of loops in the “Parent” structure and protects against deeply
nested PDFs
