Error in siging a pdf filled using itext

I am using iText to fill a pdf. This pdf contains a xfa from, I fill this form through a xml file . After filling the form user need to download it and sign it manually. So far so good everything works fine every field in form filled properly. If user sign the file adobe reader make a new copy of file with signature.
But when user try to sign that pdf it gives following error and the newly generated file with signature doesn't save data, It make all field blank.
At least one signature has problems
When user sign pdf adobe reader also give a popup on signature verification
But if i fill the same pdf manually without using itext it allow me to sign pdf successfully
this is the code that i am using to fill pdf with xml data :
public static byte[] FillXfaForm(byte[] byteArray, String xmlFilePath)
{
PdfReader reader = new PdfReader(byteArray);
using (MemoryStream ms = new MemoryStream())
{
using (PdfStamper stamper = new PdfStamper(reader, ms,'\0',true))
{
stamper.Writer.CloseStream = false;
stamper.AcroFields.Xfa.FillXfaForm(xmlFilePath);
}
if(File.Exists(xmlFilePath))
{
File.Delete(xmlFilePath);
}
return ms.ToArray();
}
}
And here is the screen shot of error message
Please help me to solve this issue.

Finally I fix this problem
The cause of this problem is that i update whole xml document to fill xfa from but when i only update the data part not the whole xml it works without any error.
I don't know what is the difference it really create as in this similar question "Bruno Lowagie" state that you can either use full xml replace or you can change data part only.
How can I set XFA data in a static XFA form in iTextSharp and get it to save?
But for me it allow me to sign the document only if I replace data part not the whole xml data.
I hope it will help someone facing similar problem.

iText GetTextFromPage exception with inline image

I have the same problem as was discussed here, which was not solved. My objective is to extract the text from an existing pdf file. I get the error message Could not find image data or EI for a certain pdf, which I cannot share as a sample. It works for other pdfs, with the following code
string fileURI = "C:\\Test\\Sample.pdf";
PdfReader reader = new PdfReader(fileURI);
ITextExtractionStrategy strategy = new LocationTextExtractionStrategy();
string s = PdfTextExtractor.GetTextFromPage(reader, 1, strategy);
Debug.WriteLine(s);
I am using iTextSharp 5.5.0 and tried changing found == 1 to found <= 1 as suggested in other posts. It does not help.
Would it help to remove all images in the pdf? I really just need the text. Which commands from iText could help me with this?

I downloaded the trial version of Acrobat to create a version of the pdf file, that I could share. After opening the file and saving it again as "Optimized PDF" over the Acrobat, the code was working and I could extract the text.
So the solution to the problem is probably opening each file in Acrobat and saving it again with the right settings using the Acrobat reference and then extracting the text.

How to convert docx to html file using open xml with formatting

I know there are lot of question having same title but I am currently having some issue for them I didn't get the correct way to go.
I am using Open xml sdk 2.5 along with Power tool to convert .docx file to .html file which uses HtmlConverter class for conversion.
I am successfully able to convert the docx file into the Html file but the problem is, html file doesn't retain the original formatting of the document file. eg. Font-size,color,underline,bold etc doesn't reflect into the html file.
Here is my existing code:
public void ConvertDocxToHtml(string fileName)
{
byte[] byteArray = File.ReadAllBytes(fileName);
using (MemoryStream memoryStream = new MemoryStream())
{
memoryStream.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument doc = WordprocessingDocument.Open(memoryStream, true))
{
HtmlConverterSettings settings = new HtmlConverterSettings()
{
PageTitle = "My Page Title"
};
XElement html = HtmlConverter.ConvertToHtml(doc, settings);
File.WriteAllText(#"E:\Test.html", html.ToStringNewLineOnAttributes());
}
}
}
So I just want to know if is there any way by which I can retain the formatting in converted HTML file.
I know about some third party APIs which does the same thing. But I would prefer if there any way using open xml or any other open source to do this.

PowerTools for Open XML just released a new HtmlConverter module. It now contains an open source, free implementation of a conversion from DOCX to HTML formatted with CSS. The module HtmlConverter.cs supports all paragraph, character, and table styles, fonts and text formatting, numbered and bulleted lists, images, and more. See https://openxmldeveloper.org/

Your end result will not look exactly the way your Word Document turns out, but this link might help.

You might want to find an external tool to help you do this, like Aspose Words

You can use OpenXML Viewer extension for Firefox for Converting with formatting.

This works for me. Hope this helps.

Creating report with Aspose.Word without losing formatting

I am using Aspose.Words to create reports from a template file (.docx filetype).
After using Aspose.Words to modify the template file and saving it into a new file, the formatting of the template file were lost (such as bold text, comments, etc).
I have tried:
Aspose.Words.Document doc = new Document(inputStream);
var outputStream = new MemoryStream();
doc.Save(outputStream, SaveFormat.docx);
What I did not expect is that outputStream is much less bytes than inputStream although I have yet to make any modification on doc. It may the reason why the report file lose their formatting.
What should I try now?

Ok, the problem is because the current version of Aspose.Words I'm using does not support docx filetype. But it still can read text of a .docx file, and only text(without any associated formatting).

Can I fill in an encrypted PDF with iTextSharp?

I have a fillable, saveable PDF file that has an owner password (that I don't have access to). I can fill it out in Adobe reader, export the FDF file, modify the FDF file, and then import it.
Then I tried to do it with iText for .NET. I can't create a PdfStamper from my PdfReader because I didn't provide the owner password to the reader. Is there any way to do this programmatically or must I recreate the document?
Even using FdfReader requires a PdfStamper. Am I missing anything? Anything legal that is - I'm pretty sure I could hack the document, but I can't. Ironically, recreating it would probably be ok.

This line will bypass edit password checking in iTextSharp:
PdfReader.unethicalreading = true;

[I found this question several months after it was posted and I'm posting this solution now for anyone who comes across this question in a search.]
I was in the exact same situation: my customer had a PDF with fillable fields that I needed to programmatically access. Unfortunately the PDF was password protected and they didn't have the password so I found couldn't work with their file.
What I discovered was that iTextSharp version 4.0.4 (and later) enforces password restrictions, earlier versions did not.
So I downloaded version 4.0.3 and sure enough it worked. In my case I didn't even have to change my code to use this older version.
You can download 4.0.3 (and all other versions) at SourceForge.

Two important things
Set PdfReader.unethicalreading = true to prevent BadPasswordException.
Set append mode in PdfStamper's constructor, otherwise the Adobe Reader Extensions signature becomes broken and Adobe Reader will display following message: "This document contained certain rights to enable special features in Adobe Reader. The document has been changed since it was created and these rights are no longer valid. Please contact the author for the original version of this document."
So all you need to do is this:
PdfReader.unethicalreading = true;
using (var pdfReader = new PdfReader("form.pdf"))
{
using (var outputStream = new FileStream("filled.pdf", FileMode.Create, FileAccess.Write))
{
using (var stamper = new iTextSharp.text.pdf.PdfStamper(pdfReader, outputStream, '\0', true))
{
stamper.AcroFields.Xfa.FillXfaForm("data.xml");
}
}
}
See How to fill XFA form using iText?

Unless someone else chimes in, I'll assume the answer is "No"
I wound up regenerating the PDF in an unencrypted form.
