If you would find chapter 8 online, then you would have found
an illegal copy of the book. Please report this, so that the
publisher can take action to remove that copy from the internet.

In other words: you've posted a request to a public mailing list
asking for something that is illegal.

The start of your code was right.
Once you have the StructTreeRoot, you need to inspect the K entry
(the Kids or children):

PdfDictionary catalog = reader.getCatalog();
PdfDictionary struct = catalog.getAsDict(PdfName.STRUCTTREEROOT);
inspectChild(struct.getDirectObject(PdfName.K));

Writing the method inspectChild is up to you (you'll use this
method recursively). Consult ISO-32000 to find out which types
of direct object can be returned.

No, that doesn't make sense.

Some images (such as WMF files) are translated into PDF syntax.
The bit and bytes of other images (such as JPEGs) are kept as-is.
And images such as GIFs and PNGs are decoded and changed into
some kind of bitmap that is zipped (see chapter 10 of the second
edition of iText in Action).

You can't just "take an Image instance" and resize it.
You need to take the bits and bytes you've been feeding to the
construct the Image instance and resize the original image.

[iText-questions] Image manipulation

If I have an instance of com.itextpdf.text.Image, how do I get the
actual bytes of the image?  

I need to take an Image instance, and resize it dynamically (which I
assume I need to do via java graphics, not iText).  Then I need to take
that resized image and convert it back to a com.itextpdf.text.Image so I
add it to a button.

Would you share example documents demonstrating the problem?

Indeed Acrobat and Reader have more requirements concerning the validity of
signatures than the mere matching of the hash value. They also allow only a
very limitted set of additions to the file after signing. These requirements
have become stricter and stricter for quite some time. And they may depend
on information in the early stage of the PDF.

[iText-questions] how do we read PdfStructureTreeRoot back from Tagged PDF

2010-03-30 Thread Chenping Ni

I have been trying to read marked content back in iText 2.1.7.

Marketcontent.pdf was written by the code in Appendix F of the first
edition Itext in Action book.

 

How do I read the PdfStructureTreeRoot back from the tagged PDF?

 

I did the following:

 

PdfReader reader = new PdfReader("marked_content.pdf");

PdfDictionary catalog = reader.getCatalog();

PRIndirectReference treeRoot =
(PRIndirectReference)catalog.get(PdfName.STRUCTTREEROOT);

(I have tried PdfDictionary treeRoot =
(PdfDictionary)catalog.get(PdfName.STRUCTTREEROOT, getting class casting
issue).

 

By looking at treeRoot, it is almost empty, cannot find the tree nodes
e1,e2,e3 and their content.

 

What is the rups?  Can I get tree structure back using rups without GUI?

Again, how do I read PdfStructureTreeRoot from a tagged pdf file?

 

Thank you very much!

 

Tom

Look at the parser package (com.itextpdf.text.pdf.parser) - you can start
with the PdfContentReaderTool as a starting point.  I think you'll find that
this will greatly simplify your efforts.

Only caveat:  I don't know if the parser has been ported to iTextSharp yet.

Subject: [iText-questions] Multiple signatures and verification by Acrobat

I am using iText to sign a document, save it to a file, read that file,
add another signature, and save it to a second file. If I read my output
files and verify the signatures with iText, they both verify. If I open
the once-signed with Adobe Acrobat, it shows the signature as valid. I
expected that if I opened the twice-signed file with Acrobat it would
show both signatures as valid, but it shows the second signature as
valid and the first as invalid.

If I view the signature properties of the first signature (in the
twice-signed file) and compute modifications, it says that there have
been no changes made since the signature was applied. If I view the
signed version, the signature shows as valid.

As expected, if I open the twice-signed file in a hex editor and
truncate everything after the \n%%EOF\n (0a 25 25 45 4f 46 0a), it is
identical to the once-signed file.

Am I doing something wrong, or am I misunderstanding how Acrobat should
work?

File sourceFile = new File( "data/source.pdf" );
File signedFile = new File( "data/signed.pdf" );
File twiceSignedFile = new File( "data/twicesigned.pdf" );

// Read from the source file and write to the signed file
PdfReader sourceReader =
  new PdfReader( new FileInputStream( sourceFile ) );
FileOutputStream signedFileOut = new FileOutputStream( signedFile );

Subject: Re: [iText-questions] how to bypass owner password of pdf

Hm and I thought that we developers are logical beings but as it seems my 
assumption was wrong.

First of all the idea behind encrypting documents is all about making the 
document not available to anyone without proper authorization, hence having a 
password to "unlock" it.

Second, if let's say there where these mechanisms to be able to bypass such 
security measures, posting these kind of information on a public mailing list 
would be, not to say, at least idiotic.

Saying that the customer has given permissions to use the documents, can't be 
proven by anyone on this list.

So to conclude this, since you say that your customer provides you with 
permissions to use his documents, he/she should also provide you the password 
to be able to process the pdf's or tell him not to apply a password in the 
first place.

Hello,

 

as of iText 5.0.1, all decrypting of encrypted PDFs can be done by the default 
password "OpenSesame".

 

Have fun,

[iText-questions] Multiple signatures and verification by Acrobat

2010-03-30 Thread Stephen Byrne

I am using iText to sign a document, save it to a file, read that file,
add another signature, and save it to a second file. If I read my output
files and verify the signatures with iText, they both verify. If I open
the once-signed with Adobe Acrobat, it shows the signature as valid. I
expected that if I opened the twice-signed file with Acrobat it would
show both signatures as valid, but it shows the second signature as
valid and the first as invalid.

If I view the signature properties of the first signature (in the
twice-signed file) and compute modifications, it says that there have
been no changes made since the signature was applied. If I view the
signed version, the signature shows as valid.

As expected, if I open the twice-signed file in a hex editor and
truncate everything after the \n%%EOF\n (0a 25 25 45 4f 46 0a), it is
identical to the once-signed file.

Am I doing something wrong, or am I misunderstanding how Acrobat should
work?



File sourceFile = new File( "data/source.pdf" );
File signedFile = new File( "data/signed.pdf" );
File twiceSignedFile = new File( "data/twicesigned.pdf" );

That's the whole point of "shared secret". So that only those who have the

No chance of any crime or anything criminal. The providers of the file have

I'm not a lawyer, but it seems to me anyone providing you with the requested

Perhaps you should ask the owner of the PDF for the password.

[iText-questions] How to align the top of two columnTexts?

2010-03-30 Thread Peter . Henningsen

Hi, 

I have been searching and experimenting for some time now, but found no 
suitable solution (I got the book!). Maybe you have? 

The problem: 
I have two columns on one page to fill with content. No problem doing 
this, but the visible top of both 
columns is not aligned consistently. 
Columns are constructed via setSimpleColumn and filled in composite mode. 
iText version is 2.1.7

Positive example: The first item in the left column is an image (scaled to 
fit), the first item in the right column is a big title text. 
Image and Text are added using seperate columntext objects for each 
column. 
The top of the image is about half the fontsize higher than the top of the 
title text's glyphs UNLESS I use ct_title.setUseAscender(true)on the left 
column. 
So I do that and problem solved. 

Negative example 1: The first item in the left column is an image (scaled 
to fit) followed by body text. The text (one font-size only) runs down the 
left column 
and is continued in the right column. Here, ct_textbody.setUseAscender(
true) has no effect on the top of the right column. 

Negative example 2: The first item in the left column is a Paragraph with 
big font followed by body text. The text (one font-size only) runs down 
the left column 
and is continued in the right column. Here again, 
ct_textbody.setUseAscender(true) has no effect. 

So, is there a way to force columntext to kind of "re-do" its "first-line 
routine" when doing setSimpleColumn() on the right, before go()? 
Calling setUseAscender(true)once more before setSimpleColumn() did not 
change a thing. 

Thanks, 
Peter--

Well, what should I make of this if part 4 is not yet

It just seems. The ID should be a (public) property of
PdfObject, imho, or at least there should be some utility
method returning it given a PdfObject instance. I've browsed
the classes for such property/method. None found, but there are
plenty of classes. Btw, I'm using iTextSharp.

[iText-questions] Sign PDF with Timestamp

2010-03-30 Thread Alex111


Hello,

I have tried to sign a pdf for several days now, but cannot get it to work.
I am using itextsharp 5.0.0.

I have code for signing a pdf with an external TSA:

In this code I get the Timestamp with the following code:

byte[] timeStampToken =X509Utils.GetTimestampToken(TsaServerUrl, null, null,
timeStampHash);


Now I want to create the timestamp myself for testing purposes, so I
replaced the above line with:

System.Security.Cryptography.X509Certificates.X509Certificate2 WinCert =  
GetCertificate();
Org.BouncyCastle.X509.X509Certificate cert =
DotNetUtilities.FromX509Certificate(WinCert);

AsymmetricKeyParameter key =
   
DotNetUtilities.GetRsaKeyPair((RSACryptoServiceProvider)WinCert.PrivateKey).Private;

TimeStampTokenGenerator TokenGen = new TimeStampTokenGenerator(
key, cert, TspAlgorithms.Sha1, "1.2");

TimeStampResponseGenerator RespGenerator =
new TimeStampResponseGenerator(TokenGen,
TspAlgorithms.Allowed);

TimeStampResponse response = RespGenerator.Generate(
request, cert.SerialNumber,
DateTime.UtcNow);
byte[] timeStampToken = response.TimeStampToken.GetEncoded();


But this does not work as expected. In the first case AdobeReader shows that
all is correct, but in the second case AdobeReader shows that there is a
problem with validating the certificate. AdobeReader also does not recognize
that there is a timestamp there.

Anybody who knows how to create the TimeStampToken correctly?

Regards,

Alex

It should works directy but you need to look at the params dictionary to
know if it's a g4 or g3 code. Note that apparently nobody knows how to
create correct G3/G4 code so you should expect errors even if other
viewers work correctly.

be proven by anyone on this list.

So to conclude this, since you say that your customer provides you with
permissions to use his documents, he/she should also provide you the
password to be able to process the pdf's or tell him not to apply a password
in the first place.
