填充PDF文件使用iTextSharp的经过，形式不删除可保存/使用权 [英] After filling PDF with iTextSharp, form is not savable/ usage rights removed
问题描述
我目前工作在将使用iTextSharp的，以部分填补PDF表单的过程。这种形式，然后通过电子邮件发送给用户，并且该用户将完成填写表格。然后提交表单通过电子邮件回到我们的电子邮件帐户，然后再进行处理。
I am currently working on a process that will use iTextSharp to partially fill a PDF form. This form is then emailed to a user and the user will finish completing the form. Then the form is submitted by email back to our email account and then processed.
我的问题是，一旦PDF被发送到一个用户，当用户打开的形式和数据无法保存。被用作模板原始的PDF可填写一个保存。不知何故，使用iTextSharp的过程中，该形式是失去其使用权。有没有办法保留使用权在使用iTextSharp的？
My problem is that once the PDF is sent out to a user, when the user opens the form and the data can not be saved. The original PDF that is used as a template can be filled out an saved. Somehow, during the process of using iTextSharp, the form is losing its usage rights. Is there a way to retain the usage rights while using iTextSharp?
我希望这里有人能指出什么错误，或点我在正确的方向。感谢您的时间和帮助。
I am hoping that someone here can point out what is going wrong, or point me in the right direction. Thanks for your time and help.

foreach (var prop in properties)

if (propval != null)

{
if(Convert.ToDateTime(propval).Year < 1902)continue;
}
formFields.SetField(name, propval.ToString());
}
}
reader.RemoveUsageRights();
stamper.Close();
reader.Close();
File.Copy(OutputItextPdfPath, Path.GetDirectoryName(OutputItextPdfPath) + "/" + logid + ".pdf");
Console.WriteLine("finished");
Console.ReadLine();
}
}
}
再次感谢您的任何指针或帮助，你可以给我。
Once again, thanks in advance for any pointers or help that you can offer me.
推荐答案
答案被注释掉在你自己的源$ C $ C。
The answer is commented out in your own source code.
您需要：
var stamper = new PdfStamper(reader, new FileStream(...), '\0', true);
来代替：
var stamper = new PdfStamper(reader, new FileStream(...));
您的问题是<一个副本href="http://stackoverflow.com/questions/21945972/how-to-correctly-fill-in-xfa-form-data-using-itextsharp-to-allow-editing-and-sav">How在XFA表单数据使用iTextSharp的，允许在Acrobat XI 编辑和保存结果正确填写 你可以在这里找到更详尽的答案。
Your question is a duplicate of How to correctly fill in XFA form data using iTextSharp to allow editing and saving result in Acrobat XI and you can find a more elaborate answer here.
另外：你抱怨的使用权被删除，但如果是这样的话，为什么我看到这条线在code：
Also: you complain that the usage rights are removed, but if that is so, why do I see this line in your code:
reader.RemoveUsageRights();
这行删除的使用权和therfore形式可以不再在本地使用Adobe Reader的时候保存。
That line removes the usage rights and therfore the form can no longer be saved locally when using Adobe Reader.
