Thanks, that worked out fine. Pity the documentation is not that good, but as a side effect I found out about generating a document from Xml or via document.Add.

Only difference is I used Server.MapPath to get the file, and saved the 'stamped' document to a MemoryStream that is then streamed to the user. Didn't use FormFlattening either - what is the advantage of using it?

Also, how do you change author, subject, keywords etc using PdfStamper/Reader?

using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;

public static void CopyDocumentTest()
{
   int pageNumber = 1;
   PdfReader reader = new PdfReader("New Document.pdf");
   Rectangle size = reader.GetPageSizeWithRotation(pageNumber);
   Document document = new Document(size);
   PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("Copy of New Document.pdf", FileMode.Create, FileAccess.Write));

   //set document info
   document.AddTitle("Document copied using iTextSharp");
   document.AddAuthor("Joachim Tesznar");
   document.AddSubject("Dynamic Content");
   document.AddCreator("PDF Form Tool by Joachim Tesznar");

   document.Open();

   PdfContentByte cb = writer.DirectContent;
   document.NewPage();
   PdfImportedPage page = writer.GetImportedPage(reader, pageNumber);
   cb.AddTemplate(page, 0, 0);
   document.Close();
}

Dear All

I'm using iTextSharp to create PDF file in my ASP.NET Page. I'm using True Type Font(Amazone BT) in this pdf file.

The Problem is When I deploy this application on the server. On the server Its running fine but when I run this web application from a  client machine it changes the font. 

It runs fine if i copy the font on client as well. But its a web application so we cannot copy the font on every client if we are using on the internet.

So how can it possible PDF file should use the font from server not from client machine.

please help me!

PdfReader pdfSource = new PdfReader(sSource);
PdfStamper pdfDest = new PdfStamper(pdfSource, Response.OutputStream);
AcroFields aFields = pdfDest.AcroFields;
aFields.SetField("FieldName", "Value");
pdfDest.Close();

The PDF is being written to the page's Response.OutputStream. One thing that I noticed when I was saving the submitted PDF form was that I had to reference the form variables like this:

Request["form1[0].#subform[0].txtFirst[0]"];

In this instance I would be inserting the data into the form like this:

aFields.SetField("txtFirst", "Value");

The fact that I am not getting an exception errors tells me that I am just not referencing the form fields correctly.  Thanks for your help.

2. The PDF has a submit button, upon submit the data will be sent to my IIS web server.

3. I should be able to read this XML and get the meaningful data to be stored elsewhere. (this is where i'm stuck with the crazy image chunk in the XML when there is an image field with an option to user to select a file!!)

4. Later when the customer wants to edit, I SHOULD BE able to re-populate the data in the PDF and display them..

preconditions:
My customer has only Acrobat Reader. (I CAN NOT afford to buy license to 100s of end users)

Any of you guys know how to do this using iTextSharp? is it possible? I tried a few of the code snippet given here, but it does not help, may be because its not yet upgraded to support 7.0.

Any better way to approach this problem???

iTextSharp support it, any way, seems you do not need itextsharp from your requirement.

btw, not iTextsharp does not version 1.6 PDF form, it does not support adobe designer Form.

if you want iTextSharp also support adobe designer form, you need do some extra job.

have a look

Demo: Fill and Save PDF Form online(also can add more function,such as email and save data to database ),Adobe Reader is enough .

Good luck!

I seem to have resolved my problem.  It was the way I was referring to the fields in my PDF form. I found an article that describes how to do it and the code.  Although part of this article says that iTextSharp cannot populate PDF forms created in Adobe Designer, this code worked for me.  I'm guessing that maybe when this post was made iTextSharp may not have been able to do it.  I am using 3.1.2.0 and it populates a PDF form generated in Adobe Designer v7. 

Here's the link:

I have a PDF file generated from my webform using ABCPdf but since it can't handle the TH tag I can't show my datagrid header on each consecutive pages (it's a very long one) - so I started to shop around for alternatives and would like to know if iTextSharp supports this tag and how can I print my webforms html into a PDF file?

PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);

You see, it is some Javascript to add the action.

Can somebody help me out ?

thanx

I created a PDF in Adobe Designer 7.0 with the usual text fields.

I also added three RadioButtonList controls.

Populating the PDF's text fields was trivial, but selecting a PDF radio button was not.

I checked the iText (Java) documentation and found instructions. 

Here's how in C#: 

/* myRadioButton1 is what I named the Radio Button control in Adobe Designer. The "1", "2" etc. are the value automatically assigned by Adobe Designer. */

fields.SetListOption("myRadioButton1", new String[] { "1", "2", "3", "4", "5", "6" }, null);

/* this selects the second radio button. */

fields.SetField("myRadioButton1", "2");

I hope this helps someone else.

I have an input pdf file that I have to stamp with values from an XML document. Is it possible to do this with ITextSharp.

I tried examples successfully where I could create PDF files from XML using XMLParser and I could stamp data into PDF files using PDFStamper.

What I'm looking for is to stamp values into PDF files from a XML file, without having to parse out the XML input using custom code. Is that possible using ITextsharp?

I looked at XML, but it seems as though it does not have the required tags for creating forms. Plus it is probably far easier to do the document in Word, then convert to PDF and add the form fields using Acrobat.

It looks like the steps I have to take are:

- Use PdfReader to get the original PDF.

- Use PdfStamper to edit the form fields, save into a MemoryStream.

- Populate a PdfWriter document from the PdfStamper (which actually contains PdfStamper.Writer, but I dont think you can access the document part of it). Save into MemoryStream which is then sent to the user.

Don't know why you have to go through all those stages just to modify a file (only need the first two if you don't need to change the title). The last stage seems as though it would be inefficient.

Although PdfStamper does have a SetMoreInfo method that may be able to change the meta information (at least in iText, not checked if iTextSharp has this).

Pity there are no iTextSharp forums to ask on.

Can you tell me how to write pdf contents to word doc.

You are trying to use iTextSharp in a web application so you can use ASP.NET's response stream directly to write the PDF.  Your code would look something like:

            this.Response.ContentType = "application/pdf";

            Document doc = new Document();

            PdfWriter writer = PdfWriter.GetInstance( doc, this.Response.OutputStream );

            try
            {
                doc.Open();
                doc.Add( new Paragraph( DateTime.Now.ToString() ) );
                doc.Add( new Paragraph( "This is a test" ) );
            }
            finally
            {
                doc.Close();
                writer.Close();
            }

OK, let's say I have a PDF document called "Form.pdf" with 4 form fields. The form fileds are "name", "address", "postal_code" and "email".

Here's the code to create a new PDF file using "Form.pdf" as a template:

private void fillForm()
{
    string formFile = @"N:\.NET\Form.pdf";
    string newFile = @"N:\.NET\Filled-out Form.pdf";
    PdfReader reader = new PdfReader(formFile);
    PdfStamper stamper = new PdfStamper(reader, new FileStream(
                newFile, FileMode.Create));
    AcroFields fields = stamper.AcroFields;

    // set form fields
    fields.SetField("name", "John Doe");
    fields.SetField("address", "2 Milky Way, London");
    fields.SetField("postal_code", "XX1 4YY");
    fields.SetField("email", "johndoe@hotmail.com");

    // flatten form fields and close document
    stamper.FormFlattening = true;
    stamper.Close();
}

Acrobat 5 should be enough to create a PDF form. Let me know if you're having any troubles.

XmlParser.Parse(document, HttpContext.Current.Server.MapPath("~/sample.xml"), tagmap);

Response.OutputStream.Write(m.GetBuffer(), 0, m.GetBuffer().Length);
Response.OutputStream.Flush();
Response.OutputStream.Close();

The above program is working perfectly and all i need is  HOW to display images dynamically on the streamed PDF file.
Can you help me with this??

Thanks

Hi Guys,

I'm new to iTextSharp (and general PDF devel).
Can anyboy give me some "startup" how to digital sign a PDF document?
As far as I know signed PDFs there are two kinds of.
One is simply signed - and the other one is a "Certified Document".

In Acrobat I get asked (when I am the first signer) if I want to certify the document.

And furtheron  - there tow kinds of signing - one is with a visible signature - and one is without it.

My primary goal is to
a.) open an existing PDF
b.) select a certificate from the users CertStore (CryptoAPI)
c.) create a "Certified document" with the selected key
d.) place a visula representation of it on the last page of the document.

Regards

I inserted an acro field with margins but and if i write manually it works like a charm. I managed to recover the data from the DB and put it in the empty spaces but the thing is that when i open the pdf i see the acro fields that are single line do not have problems but those that are multi-line do not fit into the created margin. The inserted text starts where the line starts, without consideration of the margin. Now, if i click into the acro field then the text fits into the space perfectly. Once i click on another place of the document, the text goes back to the beggining of the line.

How can i solve this?

Thx even for reading this, im sorry for reopening the thread and for my bad english.

            PdfContentByte content = pdfStamper.GetOverContent(1);
            content.BeginText();
            content.SetFontAndSize(baseFont, 10);

            //Populate the PDF form with the FDF key/value pairs
            AcroFields pdfForm = pdfStamper.AcroFields;
            pdfForm.SetFields(fdfReader);
            content.EndText();
            content.Stroke();

            //todo stopped jere
            pdfForm.SetFieldProperty("MemberEmail", "textfont", baseFont, null);


            //’Flatten’ (make the text go directly onto the pdf) and close the form
            pdfStamper.FormFlattening = true;
            pdfStamper.Writer.CloseStream = true;
            pdfStamper.Close();

But there is no change at all to the font.

I'm struggling to find anyone who combines filling a pdf template with data with the ability to control font?!!

Thanks

Hello,

I have a doubt. I want to merge few pdf's into one. I am able to do it using iTextSharp. However, i notice that the page numbers do not change. If i merge two pdf with 4 pages each, i would want the final merged pdf to have a page numbering from 1 - 8;  whats happening now is that i have the merged pdf with the page numbering 1-4 and again 1-4.

How do i change the page numbers of the merged pdf's ?

Thanks!

in this thread i've read a lot of people are having problems dynamically creating form fields and controlling the text size/font with the pdfstamper. i too had problems because of the shared server situation and found the easiest solution was to instead use the watermark feature of iTextsharp.

using a watermark you don't have to dynamically add any form fields... you just have to know the x and y coordinates of each field you want to "stamp". you can add as many watermarks as you want and they don't have to be opaque.... they can be any color, any size, any font installed on the server.

pdf spec is device independent so the coordinates are exactly were you would place those form fields anyway. you may have to experiement with getting the coordinates right though and depending on your application this may be impractical.

so set up your template and let it live on the server, then watermark the heck out of it

joachim said:

I had similar problem. I just downloaded a trial of the latest version of the Adobe Acrobat, which has a cool form designer tool. I used that to create the template document for my program, including adding all the form fields.

This works fine as long as you do not need to modify the template after it is created.

My code then creates the PDF documents based on this template, by filling in values from database records, into form fields programmatically.

Good luck...

Hi every one

I am using Itextsharp for converting the webpage gridview to the PDF

every thing works fine but the only thing is I want to show the gridview in PDF with wrap in text in the columns as I have some long text

in some columns.

what would be the code.

Any answers will be appreciated

Hi Everybody,

Can anyone solve my problem?

I am having Two aspx page, Main.aspx and View.aspx. In main.aspx page i am having iframe in td. The src of iFrame is View.aspx.

   In the Pageload event of View.aspx page, i am loading the pdf as inline file.

Now my user wants to edit the content of pdf(adding comments) using typewriter function.  So i want to save the pdf content as binary value in database.

please see the following link:

Don't know why you have to go through all those stages just to modify a file

You don't; like I said it's just a workaround. And yes, it's inefficient (especially if you're doing it on the server).

But if it is just the Title you are worries about, then just set the title on the form template and when the new document is created with the stamper, the Title will still be there.

hi

i am new to  iTextSharp,any one please help me to convert .doc to pdf

in several projects I used solution "wkhtmltopdf".
First I tried iTextSharp, but it does not work well with converting html file to pdf file, and sometimes happened when displaying Cyrillic.

"wkhtmltopdf" works fine, but it is an executable file

Peace

I also want to add an image whcih is created at runtime. Is there any way of using the stamper object for this (ie substitute a template field?) Or do I need to save the stamped PDF, and then run it back through the PDFWriter and add my image to the docuemnt.

I'd be grateful if anyone can suggest some code for this....

Many thanks

Rob

Thanks!

            PdfReader reader = new PdfReader(myoriginalPDFFileName);
           
            PdfStamper stamper = new PdfStamper(reader, new FileStream(
                mynewPDFFileName, FileMode.Create));
                       
            Single x=0;
            Single y=0;
            iTextSharp.text.Rectangle rect = reader.GetPageSizeWithRotation(1);
            iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(myImageName);
            if (img.Width > rect.Width || img.Height > rect.Height)
            {
                img.ScaleToFit(rect.Width, rect.Height);
                x = (rect.Width - img.ScaledWidth) / 2;               
                //y = (rect.Height - img.ScaledHeight) / 2;
                y = 0; //Set at bottom
            }
            else
            {
                x = (rect.Width - img.Width) / 2;
                y = (rect.Height - img.Height) / 2;
            }
            img.SetAbsolutePosition(x, y);

            int pageCount = reader.NumberOfPages;
            PdfContentByte underContent = stamper.GetUnderContent(pageCount);

            underContent.AddImage(img);

            // flatten form fields and close document
            stamper.FormFlattening = true;
            stamper.Close();

Dim document As New Document(PageSize.A4)

I assume there is something that needs to be configured on the IIS 7.5 server, but so far I can't find any information on the subject.

Thanks! McF

I am trying to find an open source/free class library that can convert Url to PDF. There are lots of paid libraries like abcpdf.net, PDFDuo and ConvertApi that easily convert any Url to PDF.

Can we convert Url to pdf with iTextSharp? I tried local with html files (physical/relative path), it works fine but it give some exception while converting an Internet url like www.google.com to pdf.

Can anyone helps?

Can anyone help me how to repeat the section of PDF dynamically in iTexSharp?
Actually if am able to create the pdf with AcroFields and now i want to add the section of pdf dynamically if the user increases by 4 otherwise the pdf look as it is.
