Hi,
I have a pdf document (created by a 3rd party using RealObjects
PDFreactor<http://www.realobjects.com/index.php?id=808&type=0>),
which is *not a form*. I'm trying to extract information from that PDF
using iTextSharp. I'm able to extract all the plain text (using
SimpleTextExtractionStrategy), but there is some information that is
represented with radio buttons, which does not come across in the plain
text extracted. I'm a complete beginner with iTextSharp, so I might be
overlooking something very simple. PdfReader.AcroForm returns null, and
PdfReader.AcroFields.Fields has 0 keys. How can I figure out the state of
radio buttons and checkboxes throughout the document? The documents all
have the same structure, so I don't really need the radio buttons &
checkboxes to be labelled; just having a list of items, and knowing whether
they are checked or not would be sufficient.
I've confirmed that the radio buttons are not just images using this
approach <http://stackoverflow.com/a/7993200/68936>.
If the radio buttons are not images, and they are not form fields, what are
they? Just special font characters? Graphic paths? Even in these two latter
cases it must be possible for software to go through the pdf document and
figure out which is checked and which is not?
Thanks
JImmy
