We have a copy of ISO 32000-1:2008 but still cannot figure out what iText
commands to use in order to get at the data.
Is what we are asking too difficult?
I'm just wondering, because I do not understand why someone more
experienced/knowledgeable in iText cannot simple post a snippet of code showing
us how to get at this data?
Regards
William

You need a copy of ISO 32000-1:2008, the PDF standard. That will tell you
where
everything you need is in the PDF, how to determine if a given font is embedded
(and/or subset and/or ….)

Hi,
Many thanks for your reply.
1. We have found the following:
ViewerPreferences -- property in both PdfWriter & PdfReader but this only
has a Set
AddViewerPreferences() -- again in both but this sets the preferences
SimpleViewerPreferences -- property in PdfReader only
Unfortunately, I can find no information on SimpleViewerPreferences in either
theiText in Action book on or the web.
Can anyone provide information on this property?
2. I appreciate viewer preferences are stored in the Catalog. But that was my
question - do we have to code the examination of the catalog ourselves?
Our expectation from an API is that it provides functions or similar, which
perform the actual work and which provide a simple call type interface. For
example:
string getPagelayout() -- which performs all the interrogation work and
returns the set value eg: Single page
Nevertheless, if we are to code ourselves there seems to be no documentation to
show how to do this. We'd appreciate it if someone could simple show us how to
get at the information we require. For example:
a). On the Fonts tab we can list font names - but what code do we need to test
whether any given font is embedded?
b). On the Initial View tab we need to test all fields - could someone provide
the code needed to retrieve the (say) Page layout value?
Hopefully, if someone can provide code snippets for the 2 above examples, we
will be able to develop the rest ourselves (we just need a kick-start!).
Thanks in advance.
Regards
William

I wondered why nobody else was answering this question.
Then I saw it was sent to the wrong address: to ONE and only ONE inbox,
instead of to the list.
Please make sure you always use the correct address.

What we call "setters" in Java are often translated to "properties" in
C#.
Look for a property ViewerPreferences in PdfWriter instead of for a
setter.

Viewer preferences are stored in the Catalog (the root object of the
PDF).
You'll have to examine that dictionary.
Note that the method "setViewerPreferences()" which takes an int value
is
only a shortcut provided by iText.
Viewer preferences aren't stored as integers inside a PDF.
