This is my code
String soruce="E:\\PT\\iText\\TextBox.pdf";
String destination="E:\\PT\\iText\\TextBoxOP.pdf";
PdfReader reader = new PdfReader(soruce);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(destination));
AcroFields form = stamper.getAcroFields();
form.setField("Text1", "Bruno Lowagie");
I need Bruno Lowagie Like this in pdf text field
Try This
Below is the action file with the help of which I was able to get What I needed..

I'd like to stamp text to a certain pdf with iText. As this text can be cyrillic I use a unicode font and encoding.
The following sample code represents how I do it:
string inputFile = #"sampleStamped.pdf";
PdfReader reader;
PdfStamper stamper;
FileStream fs;
byte[] binaryPdf = File.ReadAllBytes(inputFile);
reader = new PdfReader(binaryPdf);
fs = new FileStream(inputFile, FileMode.Create, FileAccess.Write);
stamper = new PdfStamper(reader, fs);
BaseFont bf = BaseFont.CreateFont("c:/windows/fonts/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
PdfContentByte cb = stamper.GetOverContent(1);
Phrase p = new Phrase();
p.Font = new Font(bf, 25, Font.NORMAL, BaseColor.BLUE);
p.Add("Sample Text");
ColumnText.ShowTextAligned(cb, PdfContentByte.ALIGN_LEFT, p, 200, 200, 0);
if (stamper != null)
stamper.Close();
if (fs != null)
fs.Close();
if (reader != null)
reader.Close();
The program works as expected and without errors. But if I want to open the stamped pdf in Acrobat Reader 11 or DC on Windows it says that there are proplems to display content and the stamped text is not there.
I use itextsharp 5.5.8.
Any idea how to fix this problem?
Thanks
This is not an issue of iText(Sharp) but a quirk (a feature?) of Adobe Reader.
Your sample file claims to be a PDF 1.2 file. Adobe Reader seems to behave differently when confronted with composite fonts in PDF 1.2 files.
You can check this by patching your sampleStamped.pdf, simply replace the first bytes %PDF-1.2 by %PDF-1.3 and open the file in Adobe Reader... no problem anymore.
Thus, you should make sure that your stamped PDF claims to be at least PDF 1.3. If you stamp your PDF 1.2 file, you can do so by creating the PdfStamper like this:
stamper = new PdfStamper(reader, fs, (char)3);
The result:
I have used iText to fill data into existing AcroForm fields in a PDF.
I am now looking for a solution to add new AcroForm fields to a PDF. Is this possible with iText? If so, how can I do this?
This is documented in the official documentation, more specifically in the SubmitForm example. When using a tool such as iText, you should read the official documentation first ;-)
Anyway, I've written you a simple example called AddField. It adds a button field at a specific position defined by new Rectangle(36, 700, 72, 730).
public void manipulatePdf(String src, String dest) throws DocumentException, IOException {
PdfReader reader = new PdfReader(src);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));
PushbuttonField button = new PushbuttonField(
stamper.getWriter(), new Rectangle(36, 700, 72, 730), "post");
button.setText("POST");
button.setBackgroundColor(new GrayColor(0.7f));
button.setVisibility(PushbuttonField.VISIBLE_BUT_DOES_NOT_PRINT);
PdfFormField submit = button.getField();
submit.setAction(PdfAction.createSubmitForm(
"http://itextpdf.com:8180/book/request", null,
PdfAction.SUBMIT_HTML_FORMAT | PdfAction.SUBMIT_COORDINATES));
stamper.addAnnotation(submit, 1);
stamper.close();
}
}
As you can see, you need to create a PdfFormField object (using helper classes such as PushbuttonField, TextField,...) and then use PdfStamper's addAnnotation() method to add the field to a specific page.
My application is grabbing pdf bytes from our db and sending the pdf to an iframe, using the itextsharp library. When the pdf is displayed in the iframe, the toolbar and navigation pane show, but we'd like to hide those. When I load a pdf document by simply typing in the pdf's url with #toolbar=0&navpanes=0, I see the result I'm looking for.
The application logic is using PdfStamper to add some buttons and other data to the pdf. When I write the pdf to the Response.Outputstream, the pdf shows up with the added buttons, and all is good except that I can't get rid of the toolbar and navpanes. I've tried adding "toolbar=0&navpanes=0" to the url in the response header, but to no avail.
I've written a test application which shows that using PdfSmartCopy instead of the stamper works perfectly - the pdf is shown in the browser which hides the toolbar and navpane by default.
The problem is that I still need to add some buttons to the pdf via the stamper. I've written a test app which adds the buttons via the stamper, then the smart copy grabs each page from the stamper and writes all this out to the Response.Output. The pdf shows in the browser with no toolbar or navpanes, but the buttons are not there.
Here is the code which uses both the stamper and the smart copy - your help is greatly appreciated:
private void SendStamperToCopy()
{
try
{
String filePath = #"C:\debug\PerfIndicWithDefaults.pdf";
byte[] pdfBytes = ReadFile(filePath);
Document document = new Document();
PdfSmartCopy copy = new PdfSmartCopy(document, Response.OutputStream);
document.Open();
MemoryStream memStream = new MemoryStream();
PdfReader reader = new PdfReader(pdfBytes);
PdfStamper pdfStamper = new PdfStamper(reader, memStream);
// add a button with the stamper
iTextSharp.text.Rectangle rectCancel = new iTextSharp.text.Rectangle(50, 50, 20, 20);
PushbuttonField btnCancel = new PushbuttonField(pdfStamper.Writer, rectCancel, "Cancel");
btnCancel.Text = "Cancel";
iTextSharp.text.pdf.PdfAnnotation fieldCancel = btnCancel.Field;
pdfStamper.AddAnnotation(fieldCancel, 1);
int numOfPgs = reader.NumberOfPages;
for (int n = 1; n <= numOfPgs; n++)
{
copy.AddPage(pdfStamper.GetImportedPage(reader, n));
}
String headerStr = "inline; filename=PerfIndicWithDefaults.pdf";
Response.AppendHeader("content-disposition", headerStr);
Response.ContentType = "application/pdf";
Response.OutputStream.Flush();
document.Close();
Response.OutputStream.Close();
}
catch (Exception ex)
{
Console.Write(ex);
Response.OutputStream.Flush();
Response.OutputStream.Close();
}
}
If I understand your question correctly, you want to use PdfStamper to add a button and you want to change the viewer preferences. This can be done like this:
PdfReader reader = new PdfReader(source);
System.IO.MemoryStream m = new System.IO.MemoryStream();
PdfStamper stamper = new PdfStamper(reader, m);
PdfStamper.ViewerPreferences = PdfWriter.HideToolbar | PdfWriter.PageModeUseNone;
stamper.Close();
reader.Close();
The HideToolbar will hide the toolbar, whereas PageModeUseNone means that you don't show any panels (such as the bookmarks panel, etc...).
It is not clear why you would need PdfSmartCopy in this context. Maybe I'm missing something. Also: there are some strange errors in your code: you never close the stamper instance, yet you import a page from the stamper into the copy instance. I've never seen any one try that. It's certainly not what I had in mind when I wrote iText. Your code is very confusing to me.
This is a follow up question to:
Programmatically change the color of a black box in a PDF file?
I have a pdf I created in Illustrator that has basically a black shape in the middle of the page and nothing else. I need to change the color of that shape dynamically.
From the response to the post above I am using iTextSharp (.NET C#) to get the raw contents of the PDF through ContentByteUtils.GetContentBytesForPage() and changing the color at the raw level.
Problem is that I can't find any way of saving the results back into either the original PDF or a new PDF file via iTextSharp. I'm currently stuck with a byte array of the raw contents but need to figure out how to save.
Help please!
Why are you using ContentByteUtils.GetContentBytesForPage()?
I would use:
PdfReader reader = new PdfReader(src);
byte[] content = reader.GetPageContent(pageNumber);
// do stuff with content
reader.SetPageContent(pageNumber, content);
using (FileStream fs = new FileStream(outputFile, FileMode.Create, FileAccess.Write, FileShare.None)) {
using (PdfStamper stamper = new PdfStamper(reader, fs)) {
}
}
string pdfTemplate = #"Trust App form.pdf";
string newFile = #"Trust App form Completed.pdf";
PdfReader pdfReader = new PdfReader(pdfTemplate);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(
newFile, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
pdfFormFields.SetField("trust.trustee.entityname.line1", "Gulistan-e-Jauhar Karachi");
pdfStamper.FormFlattening = false;
pdfStamper.Close();
I am able to fill pdf forms using Itext sharp pdf.
But problem is this pdf is for .net. I WANT TO USE IT IN SILVERLIGHT.
Is there any alternative? for filling pdf form in silverlight... what i think itext sharp give silverpdf (http://silverpdf.codeplex.com/) but there is pdfstamper and acrofields classes in silverpdf.
SilverPDF looks to be inspired/based-on iTextSharp and PDFSharp, but it doesn't use an identical class layout by any means.
I just poked around in their code a bit (they have no docs that I could find), and it looks like you need to get the field's PdfAcroField object from the PdfAcroForm, which you get from a PdfDocument, which in turn you get from PdfReader.open(...).
When the docs aren't good enough, check the code if at all possible.
