[poppler] Extract pdf

[Leonard Rosenthol]

Poppler doesn't expose the necessary "low level" APIs that you would need to get access to them, if present.  You'll need to get down to the original Xpdf Object classes - and to use them properly you will also need an indepth understanding of the PDF format and the relevant sections of the documention.

But yes, it is possible.

PDF DOES support rich semantic structure including all of things listed below (ISO 32000-1:2008, 14.7, 14.8 and 14.9). HOWEVER, it is optional and therefore many PDF documents do not contain the necessary elements.   And, as pointed out, without the presence of such elements already in the PDF - the best you can do is GUESS.

Hi,

I think PDF is a page description language and defines
nothing for semantic structure; how to store the titles
of section, subsection, figure and tables. Therfore, I
guess, poppler cannot extract - because, PDF does not have.

Is there any reliable framework defining such and your
target documentations follow?
