I am trying to write a text on my pdf at specific coordinate. My text is getting in pdf but the old content is also getting lost.
please suggest solution.
thanks in advance.
am using the below code for replace image and text on pdf, its is good working on the image replace part, but i dont know the how can write the text replace in same code.
private void AddAnImage()
{
string qrfile = qrcode();
using (var inputPdfStream = new FileStream(Server.MapPath("PDF/input.pdf"), FileMode.Open))
using (var inputImageStream = new FileStream(qrfile, FileMode.Open))
using (var outputPdfStream = new FileStream(Server.MapPath("PDF/output.pdf"), FileMode.Create))
{
PdfReader reader = new PdfReader(inputPdfStream);
PdfStamper stamper = new PdfStamper(reader, outputPdfStream);
PdfContentByte pdfContentByte = stamper.GetOverContent(1);
var image = iTextSharp.text.Image.GetInstance(inputImageStream);
image.SetAbsolutePosition(50, 75);
pdfContentByte.AddImage(image);
PdfContentByte canvas = stamper.GetOverContent(2);
ColumnText.ShowTextAligned(canvas, Element.ALIGN_LEFT, new Phrase(DateTime.Now.ToShortDateString()), 0, 0, 0);
stamper.Close();
}
}
I'm trying to convert HTML to PDF, but the font style isn't being properly applied to the PDF. Below is my code (using itextsharp.dll):
Document document = new Document();
FileStream fs = new FileStream(fileName, FileMode.Create);
PdfWriter.GetInstance(document, fs);
document.Open();
HTMLWorker htmlWorker = new HTMLWorker(document);
string content = radEditorCollector.Content;
if (string.IsNullOrWhiteSpace(content))
{
content = AppConstants.LetterNotConfigured;
}
htmlWorker.Parse(new StringReader(content));
document.Close();
fs.Close();
//Create document list of each debtor
PdfReader pdfReader = new PdfReader(fileName);
readerList.Add(pdfReader);
You can edit your font with pdfStamper. Here is little idea. You can manage with what you need.
PdfReader pdfReader = new PdfReader(fileName);
PdfStamper pdfStamper = new PdfStamper(pdfReader, fs);
PdfContentByte pdfContentByte = pdfStamper.GetOverContent(1);
BaseFont baseFont = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1250, BaseFont.NOT_EMBEDDED);
pdfContentByte.SetColorFill(BaseColor.BLUE);
pdfContentByte.SetFontAndSize(baseFont, 8);
pdfContentByte.BeginText();
pdfContentByte.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "Here is your settings", 400, 600, 0);
pdfContentByte.EndText();
pdfStamper.Close();
readerList.Add(pdfReader);
Update:
Change only tag settings. Use before close.
pdfStamper.AcroFields.SetFieldProperty("YOUR_TAG", "textfont",
baseFont, null);
The title sums it all.
I want to add a text to an existing PDF file using iTextSharp, however i can't find how to do it anywhere in the web...
PS: I cannot use PDF forms.
I found a way to do it (dont know if it is the best but it works)
string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";
// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);
// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();
// the pdf content
PdfContentByte cb = writer.DirectContent;
// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);
// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();
// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);
// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();
I hope this can be usefull for someone =) (and post here any errors)
In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:
using (var reader = new PdfReader(#"C:\Input.pdf"))
{
using (var fileStream = new FileStream(#"C:\Output.pdf", FileMode.Create, FileAccess.Write))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, fileStream);
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();
}
}
This worked for me and includes using OutputStream:
PdfReader reader = new PdfReader(new RandomAccessFileOrArray(Request.MapPath("Template.pdf")), null);
Rectangle size = reader.GetPageSizeWithRotation(1);
using (Stream outStream = Response.OutputStream)
{
Document document = new Document(size);
PdfWriter writer = PdfWriter.GetInstance(document, outStream);
document.Open();
try
{
PdfContentByte cb = writer.DirectContent;
cb.BeginText();
try
{
cb.SetFontAndSize(BaseFont.CreateFont(), 12);
cb.SetTextMatrix(110, 110);
cb.ShowText("aaa");
}
finally
{
cb.EndText();
}
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);
}
finally
{
document.Close();
writer.Close();
reader.Close();
}
}
Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )
public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
{
//variables
string pathin = inputPdfPath;
string pathout = outputPdfPath;
//create PdfReader object to read from the existing document
using (PdfReader reader = new PdfReader(pathin))
//create PdfStamper object to write to get the pages from reader
using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
{
//select two pages from the original document
reader.SelectPages("1-2");
//gettins the page size in order to substract from the iTextSharp coordinates
var pageSize = reader.GetPageSize(1);
// PdfContentByte from stamper to add content to the pages over the original content
PdfContentByte pbover = stamper.GetOverContent(1);
//add content to the page using ColumnText
Font font = new Font();
font.Size = 45;
//setting up the X and Y coordinates of the document
int x = point.X;
int y = point.Y;
y = (int) (pageSize.Height - y);
ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
}
}
Here is a method To print over images:
taken from here.
Use a different layer for your text you're putting over the images, and also make sure to use the GetOverContent() method.
string oldFile = "FileWithImages.pdf";
string watermarkedFile = "Layers.pdf";
// Creating watermark on a separate layer
// Creating iTextSharp.text.pdf.PdfReader object to read the Existing PDF Document
PdfReader reader1 = new PdfReader(oldFile);
using (FileStream fs = new FileStream(watermarkedFile, FileMode.Create, FileAccess.Write, FileShare.None))
// Creating iTextSharp.text.pdf.PdfStamper object to write Data from iTextSharp.text.pdf.PdfReader object to FileStream object
using (PdfStamper stamper = new PdfStamper(reader1, fs))
{
// Getting total number of pages of the Existing Document
int pageCount = reader1.NumberOfPages;
// Create New Layer for Watermark
PdfLayer layer = new PdfLayer("Layer", stamper.Writer);
// Loop through each Page
for (int i = 1; i <= pageCount; i++)
{
// Getting the Page Size
Rectangle rect = reader1.GetPageSize(i);
// Get the ContentByte object
PdfContentByte cb = stamper.GetOverContent(i);
// Tell the cb that the next commands should be "bound" to this new layer
cb.BeginLayer(layer);
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.RED);
cb.SetFontAndSize(bf, 100);
cb.BeginText();
cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "Some random blablablabla...", rect.Width / 2, rect.Height / 2, - 90);
cb.EndText();
// Close the layer
cb.EndLayer();
}
}
Can any one help me that how can I cut the PDF page like as Acrobat professional?
This snippet might help you:
public static void CropDocument(string file, string oldchar, string repChar)
{
int pageNumber = 1;
PdfReader reader = new PdfReader(file);
iTextSharp.text.Rectangle size = new iTextSharp.text.Rectangle(
Globals.fX,
Globals.fY,
Globals.fWidth,
Globals.fHeight);
Document document = new Document(size);
PdfWriter writer = PdfWriter.GetInstance(document,
new FileStream(file.Replace(oldchar, repChar),
FileMode.Create, FileAccess.Write));
document.Open();
PdfContentByte cb = writer.DirectContent;
document.NewPage();
PdfImportedPage page = writer.GetImportedPage(reader,
pageNumber);
cb.AddTemplate(page, 0, 0);
document.Close();
}
