Does Stamp.BindPdf has problems with filled out form PDFs?

Hello,

I did the following:

  • Openend a form PDF and inserted values in the form fields and saved the stream
  • then used that stream with Stamp.BindPDF to put that form PDF as a stamp on my other main PDF file
  • After applying the stamp I opened the stamped PDF and only see the stamp without the filled out fields!!! Why?

Here is the code:

using System.Collections;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using Aspose.Pdf.Kit;

using System.IO;

using System.Collections.Generic;

using Aspose.Words;

using Aspose.Words.Fields;

namespace TestWebApp

{

public partial class StamperForm : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

string currentDir = Server.MapPath("bin");

string footerPdf = Path.Combine(currentDir, "Footer.pdf");

string testPdf = Path.Combine(currentDir, "main.pdf");

string resultPdf = Path.Combine(currentDir, "test.pdf");

Dictionary<string, string> footerProperties = new Dictionary<string, string>();

footerProperties.Add("Title", "My test footer ");

footerProperties.Add("DOCID", "2010-123456");

footerProperties.Add("DOCVersion", "1.3");

footerProperties.Add("DOCStatus", "Published");

footerProperties.Add("PrintDate", "2010-03-02");

MemoryStream footerStream = GetFilledOutFooterStream(footerPdf, footerProperties);

footerStream.Seek(0, SeekOrigin.Begin);

Stamp aStamp = new Stamp();

// aStamp.BindPdf(Path.Combine(Server.MapPath("bin"), "temp.pdf"), 1);

aStamp.BindPdf(footerStream, 1);

aStamp.IsBackground = false;

PdfFileStamp stamper = new PdfFileStamp(testPdf, resultPdf);

stamper.AddStamp(aStamp);

stamper.Close();

footerStream.Close();

}

private MemoryStream GetFilledOutFooterStream(string footerPdfUri, Dictionary<string, string> footerProperties)

{

MemoryStream ms = new MemoryStream();

string extension = Path.GetExtension(footerPdfUri).TrimStart('.').ToLowerInvariant();

switch (extension)

{

case "pdf":

using (FileStream footerStream = File.OpenRead(footerPdfUri))

{

Aspose.Pdf.Kit.Form form = new Aspose.Pdf.Kit.Form(footerStream, ms);

foreach (string field in form.FieldsNames)

{

string fieldName = string.Empty;

int start = field.LastIndexOf(".");

int stop = field.LastIndexOf("[");

if (start != -1 && stop != -1)

fieldName = field.Substring(start + 1, stop - start - 1);

else

fieldName = field;

if (footerProperties.ContainsKey(fieldName))

{

form.FillField(field, footerProperties[fieldName]);

}

}

form.Save();

ms.Seek(0, SeekOrigin.Begin);

FileStream fs = File.OpenWrite(Path.Combine(Server.MapPath("bin"), "temp.pdf"));

byte[] buffer = ms.ToArray();

fs.Write(buffer, 0, buffer.Length);

fs.Close();

}

break;

case "doc":

Document doc = new Document(footerPdfUri);

FormFieldCollection ffCol = doc.Range.FormFields;

foreach (FormField field in ffCol)

{

if (field.Type == Aspose.Words.Fields.FieldType.FieldFormTextInput)

{

if (footerProperties.ContainsKey(field.Name))

{

field.Result = footerProperties[field.Name];

}

}

}

doc.Save(ms, SaveFormat.Pdf);

break;

default:

throw new InvalidOperationException("Footer file extension is not supported.");

}

return ms;

}

}

}
