Extraction of Type 3 fonts

[Jinder Aujla <ji...@gmail.com>]

Hi

Apologies if this is the wrong email to use. I am trying to understand if
and how well PDFBox supports extraction of text from a pdf document that
contains type 3 fonts. It's taken a while to understand the reason behind
the apparent failure in parsing.

Before I go further I thought it would be better to ask, in addition I did
find this ticket in JIRA but I wasn't sure if it was still relevant.

https://issues.apache.org/jira/browse/PDFBOX-124

I can use pdftotext it's not completely successful but it does extract to
some degree. Any guidance is greatly appreciated.

Thanks
Jinder

It depends on the pdf, but most likely those pdfs don't provide a mapping so
that the text of type 3 fonts can't be extracted.

It is quite easy to determine if the text of a pdf could be extracted or not.
Just perform the adobe test [1]. If adobe can't extract the text, PDFBox won't
be able to do it neither.
