Hello everyone and thanks for your help in advance. I am trying to create a web application that utilizes iTextSharp to import a multi-page pdf, the place text on the different pages, in other words a certain text for page 1, different text for page, etc.
I've successfully imported the pdf, but the text is escaping me. Here is my code:
PdfReader reader = null;
Document sourceDocument = null;
PdfCopy pdfCopyProvider = null;
PdfImportedPage importedPage = null;
int startPage = 1;
int endPage = 2;
try
{
string sourcePdfPath = Server.MapPath(path);
// Intialize a new PdfReader instance with the contents of the source Pdf file:
reader = new PdfReader(sourcePdfPath);
// For simplicity, I am assuming all the pages share the same size
// and rotation as the first page:
sourceDocument = new Document(reader.GetPageSizeWithRotation(startPage));
// Initialize an instance of the PdfCopyClass with the source
// document and an output file stream:
//
MemoryStream ms = new MemoryStream();
pdfCopyProvider = new PdfCopy(sourceDocument, ms);
//
//pdfCopyProvider = new PdfCopy(sourceDocument,
// new System.IO.FileStream(outputPdfPath, System.IO.FileMode.Create));
sourceDocument.Open();
// Walk the specified range and add the page copies to the output file:
for (int i = startPage; i <= endPage; i++)
{
importedPage = pdfCopyProvider.GetImportedPage(reader, i);
pdfCopyProvider.AddPage(importedPage);
}
PdfContentByte cb = pdfCopyProvider.DirectContent;
PdfReader reader = null;
Document sourceDocument = null;
PdfCopy pdfCopyProvider = null;
PdfImportedPage importedPage = null;
int startPage = 1;
int endPage = 2;
try
{
string sourcePdfPath = Server.MapPath(path);
// Intialize a new PdfReader instance with the contents of the source Pdf file:
reader = new PdfReader(sourcePdfPath);
// For simplicity, I am assuming all the pages share the same size
// and rotation as the first page:
sourceDocument = new Document(reader.GetPageSizeWithRotation(startPage));
// Initialize an instance of the PdfCopyClass with the source
// document and an output file stream:
//
MemoryStream ms = new MemoryStream();
pdfCopyProvider = new PdfCopy(sourceDocument, ms);
//
//pdfCopyProvider = new PdfCopy(sourceDocument,
// new System.IO.FileStream(outputPdfPath, System.IO.FileMode.Create));
sourceDocument.Open();
// Walk the specified range and add the page copies to the output file:
for (int i = startPage; i <= endPage; i++)
{
importedPage = pdfCopyProvider.GetImportedPage(reader, i);
pdfCopyProvider.AddPage(importedPage);
}
PdfContentByte cb = pdfCopyProvider.DirectContent;
//select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 12);
//write the Patient Name
cb.BeginText();
//put the alignment and coordinates here
cb.ShowTextAligned(3, "Hello", 200, 200, 0);
cb.EndText();
sourceDocument.Close();
reader.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=file.pdf");
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
Response.OutputStream.Flush();
Response.End();
}
catch (Exception ex)
{
throw ex;
}
}
sourceDocument.Close();
reader.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=file.pdf");
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);

According to your description and codes, I found you used PdfCopy to write new text to the PDF.
As far as I know, if you want to write the text to the PDF file, you should use PdfWriter.
More details, you could refer to below codes sample.

}
sourceDocument.Close();
reader.Close();
pdfCopyProvider.Close();
MemoryStream ms = startwrite(newFile);
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=file.pdf");
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
Response.OutputStream.Flush();
Response.End();
}
catch (Exception ex)
{
throw ex;
}
}
public static MemoryStream startwrite(string newpath)
{
var ms = new MemoryStream();
using (var reader = new PdfReader(newpath))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, ms);
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 12);
var multiLineString = "Hello,\r\nWorld!".Split('\n');
foreach (var line in multiLineString)
{
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
}
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
writer.Close();
return ms;
}
}
