ALL of the PDF, except the signature itself, is signed.

Thanks Paulo for your reply...
The main objective is to get the CMYK color to be the one expected on printer...
I don´t now much about color but RGB is only for screens no?
Any pointers or directions on how to achieve this?
Thanks in advance..

The group must be added to the page. I tried adding it to the XObject and it
didn't work.

You may call PdfWriter.setRgbTransparencyBlending(true) but if you expect to
get color matches without a calibrated monitor and an icc profile you're in
for some surprises.

I use iText for fill text on an AcroField and all it´s ok unless that
when I choose an Font color his way:
new CMYKColor(0, 76, 76, 70) the result that I get is like an opaque
brown (maybe a spor color) wich is diferent from the result that I
want to obtain that can be visualized on this web page:
If the group gets added to the XObject Form as opposed to the Page object, I
think that should work fine. Then there is always one-to-one correlation
between the imported page and the XObject Form containing it. I doubt that
transparency between overlapping XObject Forms will ever be an issue.

Weblogic has some proprietary types like zip: and wsjar: that are not
recognized by iText. It will be "fixed" in the near future. Meanwhile load
the file to a byte array.

I'm afraid that this doesn't have an easy solution. If there's an RGB page
group and an CMYK page group and both pages are included in a single page,
what should be the resulting page group?

Paulo,
Enclosed are two small files that demonstrate the Transparency Group
problem. The BeforeImport.pdf shows an image in a light blue color, and the
AfterImport.pdf is the same file after being imported using PdfWriter. The
color shift should be clearly noticeable in Acrobat.

Hi All,
I was trying to open a PDF file and create fields on it.
TextField tf = new TextField(stamper.getWriter(), new Rectangle(80,50,
180,100), "field1");

writer.addAnnotation (tf.getTextField());
However, when I try to get the AcroField later, stamper.getAcroFields()
returns nothing. If

Hi Tamas,
the bouncy castle components do most of the crypto processing required to build
the signature. iText does many good things, but doesn't supply crypto functions
on its own.
Maybe you think about using a central service for signing. So you doesn't have
to bother with crypto stuff in yo

Hi Bill,
Yes, I can extract the document that you attached (test_split3.pdf).
However, if you split again, then the extraction fail in the first document

This is exactly my problem! if you know about a tool that can extract the
