<br><br>Working on a project using itextsharp and vb.net where I want to produce a partially filled out PDF with editable forms and the option to sign with a digital signature.
<br><br>I had it working just fine until last week when I started getting an error when trying to save the final document in Adobe Reader. The message says:
<br>"The document could not be saved. There was a problem reading this document (26). "
<br><br>I have a template PDF with forms and extended features enabled which I want to make an editable copy of with some of the forms filled out with data from database. The idea is to be able to take the pre-filled document out on a laptop to be filled out completely and signed offline.
<br><br>The problem seems to occur as soon as I open the document with PdfStamper, set the value of a field and then close the document, using the code below. I even tried it with a blank PDF with just one field called "test" and still get the same error.
<br>' --
<br>Dim reader As PdfReader = New PdfReader(sDocTemplate)
<br>Dim stamper As New PdfStamper(reader, New FileStream(sOutputFile, FileMode.Append))
<br>stamper.AcroFields.SetField("test", "hello")
<br>stamper.Close()
<br>' --
<br><br>When I open the produced PDF there is a small window saying something about the document being damaged and repaired, then it opens and everything seems fine. The forms contain the proper data and everything, but when trying to save it the mentioned error message is displayed.
<br><br>As I said, it was working fine right up until this error appeared out of the blue. I haven't updated any relevant software that I know of and I think I've eliminated all sources of error right down to itextsharp when testing with a blank pdf.
<br><br>Any ideas of what could be wrong would be highly appreciated!

<br><br>Using iTextSharp for C# in Visual Studio 2008 .NET is it possible to read in formatted rich text data from an external source and export the formatted data on a page within a PDF Document?
<br><br>If this is not possible are there any alternative methods to reading in rich text and exporting the data with the same formatting in a PDF Document (RTF=>XML=>PDF) ? Any additional information would be appreciated. Thanks!

<br><br>I'm having problems creating PDFA-s (but only some of them).
<br><br>I used the code from this link for creation.
<br><br><br><a href="http://blog.rubypdf.com/2007/08/10/itext-and-itextsharp-support-pdfa-1-now/" target="_top" rel="nofollow">http://blog.rubypdf.com/2007/08/10/itext-and-itextsharp-support-pdfa-1-now/</a><br><br>And it works great for most of the time. But I am experiencing some difficulties for a slightly diffrent original PDF.
<br><br>Adobe's (Professional 8 & 9) preflight gives out the same message:
<br><br>Transfer curve used:
<br><br>Transfer curves are prohibited in PDF/X files. Use Acrobat Distiller 5's "Apply transfer curves" to avoid transfer curves in PDF files without compromising page contents.
<br><br>Creating the pdfa using Adobe works ok since it automatically applies the transfer curves.
<br><br>So here is my main question: Can iTextSharp be used to apply the transfer curves.
<br><br>I would like to thank you for any reply

<br><br>I'm unable to get itextsharp.dll working on an x64 Windows Server 2003. The same binary works fine on any of our 32-bit systems.
<br><br>Details:
<br>Though the itextsharp.dll library seems to be a good assembly on 32-bit systems, on a 64-bit system it seems corrupted. I've tried to check its consistency with at least two tools,
<br><br><a href="http://checkasm.booring.net/" target="_top" rel="nofollow">http://checkasm.booring.net/</a><br><a href="http://www.assemblyinspector.com/" target="_top" rel="nofollow">http://www.assemblyinspector.com/</a><br><br>and both report the assembly has an incorrect format. I've tried building itextsharp.dll with VS2008 with all 3 possible target platforms (Any, x64, x86; all for .NET 2.0), but the result is still the same. I also downloaded the itextsharp.dll binary from sourceforge.net with the same result.
<br><br>.NET 2.0 (and now even .NET 3.5) framework is installed on the machine. All dependencies of itextsharp.dll seem to be satisfied, none is missing. It seems to me that the library is wrongly built, but I've been unable to fix it.
<br><br>Can anyone help me?
<br><br>Thank you,
<br>Martin.
<br><br>P.S. My original problem was that we have a C++/CLR COM library dependent on the itextsharp.dll. But regasm.exe refuses to register it on the 64-bit platform. The error message is:
<br><br>RegAsm : error RA0000 : Could not load file or assembly 'PdfServiceLib, Version=1.0.3568.31893, Culture=neutral, PublicKeyToken=null' or one of its dependencies. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)
<br><br>I suspect itextsharp.dll to be the main reason.

<br><br>I am trying to create a pdf file from an image and setting a hidden text behind the image at defined location.
<br>All things are working well but the font does not appears good.
<br><br>i am using following code:-
<br><br>FontFactory.RegisterDirectory(@"C:\WINDOWS\fonts");
<br>FontFactory.RegisterDirectory(@"C:\WINDOWS\fonts\Arial.ttf");
<br>FontFactory.RegisterDirectory(@"C:\WINDOWS\fonts\Times New Roman.ttf");
<br><br>chunk = new Chunk("New Zealand Trained Nurses' Association", FontFactory.GetFont("Times New Roman", "Cp1252", BaseFont.EMBEDDED, 20, 0, iTextSharp.text.Color.RED));
<br>chunk.SetTextRenderMode(PdfContentByte.TEXT_RENDER_MODE_FILL, 0, iTextSharp.text.Color.MAGENTA);
<br>rect = new iTextSharp.text.Rectangle(184, 1063, 376, 1063);
<br>ct.SetSimpleColumn(rect.Left, rect.Bottom, rect.Right, rect.Top, 0, 0);
<br>ct.AddText(chunk);
<br>ct.Go();
<br><br><br>The font i passed in chunk '<b>Times New Roman</b>' but when i copy the text from the pdf file and paste it in Microsoft Word it shows the font '<b>TimesNewRomanPSMT</b>' while the font size and color are same as i passed in chunk.
<br><br>Can some one tell me where i made mistake.
<br><br>Thanks in Advance

<br>there's sample how to add timestamp using certificate in file:
<br><a href="http://itextpdf.sourceforge.net/howtosign.html#signtsocspcs" target="_top" rel="nofollow">http://itextpdf.sourceforge.net/howtosign.html#signtsocspcs</a><br><br>but i can't find sample, how to add timestamp using etoken (smartcard should be pretty much the same).
<br><br>the part, that i don't know how to change is:
<br><br>Pkcs12Store ks = new Pkcs12Store(fs, CERT_PASSW.ToCharArray());
<br>ICipherParameters pk = ks.GetKey(alias).Key;
<br><br>because in Pkcs12Store constructor they are using parameter to certificate file stream, i have my certificate as X509Certificate2 object.
<br><br>If anyone done this and could help, i would be very thankfull.

<br><br>I would like to put a digital signature to an existing PDF document. In all of the IText documentation I found a desctiprion about how to sign a PDF and all of the ways use Bouncy Castle classes to encrypt the document hash.
<br><br>eg:
<br><br>PdfStamper st = PdfStamper.CreateSignature(reader, new FileStream(this.outputPDF, FileMode.Create, FileAccess.Write), '\0', null, true);
<br><br> st.MoreInfo = this.metadata.getMetaData();
<br> st.XmpMetadata = this.metadata.getStreamedMetaData();
<br> PdfSignatureAppearance sap = st.SignatureAppearance;
<br>
<br> sap.SetCrypto(this.myCert.Akp, this.myCert.Chain, null, PdfSignatureAppearance.WINCER_SIGNED);
<br>...
<br>st.Close();
<br><br> I have already had an encrypted signed hash (created from the pdf document content and a MyCert.pfx) and I'd like to insert, append (I dont know where to) this existing signature to the existing PDF.
<br><br>Does anybody know what should I use?
<br><br>Any help would be appreciated.

<br><br>What part of the pdf document is signned when I use the PdfStamper.CreateSignature and the PdfSignatureAppearance.SetCrypto method?
<br><br>My code is the folowing:
<br>PdfStamper st = PdfStamper.CreateSignature(reader, new FileStream(this.outputPDF, FileMode.Create, FileAccess.Write), '\0', null, true);
<br> st.MoreInfo = this.metadata.getMetaData();
<br> st.XmpMetadata = this.metadata.getStreamedMetaData();
<br> PdfSignatureAppearance sap = st.SignatureAppearance;
<br>
<br> sap.SetCrypto(this.myCert.Akp, this.myCert.Chain, null, PdfSignatureAppearance.WINCER_SIGNED);
<br>...
<br> st.Close();
<br><br>After I signed an existing pdf document I modified some of the bytes randomly and several times the adobe reader 9 informed me about that all of the signatures are valid. How did it happend? I looked over the pdf 1.4 documentation and I found that the whole pdf and only a part of the pdf can be signed as well. When I use the PdfStamper.CreateSignature which part of the pdf doc will be signed?
<br><br>Thanks

<br> X509Certificate[] chain = new X509Certificate[x.Length];
<br> for (int k = 0; k < x.Length; ++k)
<br> {
<br> chain[k] = x[k].Certificate;

<br><br>This code work fine. But when I use X509Certificate2 from certificate store I can't convert its private key to ICipherParameters.
<br><br>Is it possible? Can I use X509Certificate2 for signing with timestamp?
<br><br>I get certificate and certificate chain with:
<br><br>//get certificate from certificate store, this certificate has exportable private key
<br>X509Certificate2 certificate = GetCertificate();
<br>X509CertificateParser cp = new X509CertificateParser();
<br>X509Certificate[] chain = new[] { cp.ReadCertificate(certificate.RawData) };

<br><br>After analyzing the questions posted in this mailing list I came to the conclusion that most of them are not specifically .Net related and could be answered in a C# or Java environment. To avoid dispersing the know-how and to increase the chance of getting an answer I'm closing this mailing list and ask you to post your iTextSharp questions in the iText mailing list.
<br><br>You can subscribe to the iText mailing list at <a href="https://lists.sourceforge.net/lists/listinfo/itext-questions" target="_top" rel="nofollow">https://lists.sourceforge.net/lists/listinfo/itext-questions</a>.

<br><br>Here are some fixes to embedded attachment handling.
<br><br>PdfEncodings.cs: Changed behavior of loading attachment object names.
<br>Might have side effects elsewhere. In my opinion Unicode should be used
<br>internally to process all strings. Raw version can be kept handy if needed.
<br><br>Anyway. This was needed when embedded attachment object name was in
<br>Unicode and iTextSharp saved new attachment with Ascii version. Now
<br>Acrobat Reader 9.1 failed to handle files properly.
<br><br>PdfFileSpecification.cs: Contains bugfixes to wrapper functions. Also
<br>removes the need to make indirect object for data. Generates smaller PDF
<br>file and smaller catalog.
<br><br>PdfName.cs: Couple of new tokens.
<br><br>PdfStamperImp.cs: If attachments were added, it would generate new
<br>EmbeddedFiles entry in the written PDF file. This fixes it so that
<br>previous EmbeddedFiles entry is removed.
<br><br>PdfStream.cs: Keeps track of original attachment size in DL.
<br>Documentation fixes.
<br><br>PdfSignatureAppearance.cs: Documentation fixes.
<br><br>Thanks,
<br>Vesa Jääskeläinen

<br>In Acrobat 9 only the last signature is marked as valid but the other ones

<br>Subject: [itextsharp-questions] Transparency Groups
<br><br><br>Paulo,
<br><br>I've come across a case where we import a page from an existing PDF document
<br>and the color of an image does not match the original after the import.
<br>Basically, all we're doing is
<br><br>PdfImportedPage page = writer.GetImportedPage(reader, pageNumber);
<br>writer.DirectContent.AddTemplate(page, scaleX, 0, 0, scaleY, translateX,
<br>translateY);
<br><br>where the writer is a PdfWriter. If I use PdfCopy, the color will match.
<br>Upon examining the generated PDFs, I found that the images are indeed
<br>identical, but the Page object is missing a Group dictionary when I use
<br>PdfWriter. There is no Group dictionary in the XObject Form either. In the
<br>original file, the Group in the Page dictionary is like this:
<br><br>/Group<</CS/DeviceRGB/S/Transparency/Type/Group>>
<br><br>This is preserved when I use PdfCopy and, as far as I can tell, is the only
<br>thing that can explain the color difference.
<br><br>Is this perhaps a bug? The Group dictionary is a 1.4 feature according to
<br>Adobe so I would think it should be supported when generating 1.4 or 1.5
<br>files. Is there a way for me to set something in the PdfWriter to insure
<br>this gets included?
<br><br>Thanks - Gylfi
