Subject: [iText-questions] Text paragraph font size is changed
Hello,
Thanks for the great library for generating PDF! :-)
I have a question about iTextSharp library: After some data are bound to
text fields, the paragraph font size is slightly changed. I don't know
why?
The attached screenshot shows a sample (Left side is PDF template, right
side is the generated PDF file). You can see "Sincerely" is not in the
same horizontal line. The attached "SampleJS.pdf" is the PDF template.
The main C# web site code is like below:
------------------------------------------------------------------------
-----------------------------
protected void BtnGetPDF_Click(object sender, EventArgs e)
{
// Get PDF stream
MemoryStream m = new MemoryStream();
CreatePDFStream(m);
// Get stream bytes
byte[] buffer = m.GetBuffer();
// Save a copy to file for debug purpose only
FileStream fs = new
FileStream(Server.MapPath("testPDF.pdf"), FileMode.Create);
fs.Write(buffer, 0, buffer.Length);
fs.Close();
// Write pdf bytes to outputstream
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Accept-Header",
buffer.Length.ToString());
Response.AddHeader("Content-Length",
buffer.Length.ToString());
Response.OutputStream.Write(buffer, 0, buffer.Length);
Response.Flush();
Response.End();
}
/// <summary>
/// Create PDF stream
/// </summary>
private void CreatePDFStream(Stream m)
{
iTextSharp.text.pdf.PdfReader pdfRd = new
iTextSharp.text.pdf.PdfReader(Server.MapPath("~/SampleJS.pdf"));
iTextSharp.text.pdf.PdfStamper stamp = new
iTextSharp.text.pdf.PdfStamper(pdfRd, m);
// Set form fields
// NOTE: It is supposed to get data from database
iTextSharp.text.pdf.AcroFields fields = stamp.AcroFields;
string formText = fields.GetField("formText");
formText = formText.Replace("<Institution>",
txtInstitution.Text);
formText = formText.Replace("<AppID>", txtAppID.Text);
formText = formText.Replace("<CurrentDate>",
DateTime.Now.ToString());
formText = formText.Replace("<Name>", "John Nolan");
formText = formText.Replace("<AddressStreet>", "123 test
street");
formText = formText.Replace("<AddressCity>", "Frederick");
formText = formText.Replace("<AddressState>", "MD");
formText = formText.Replace("<AddressZip>", "20120");
formText = formText.Replace("<FirstName>", "John");
formText = formText.Replace("<LoanType>", txtLoanType.Text);
formText = formText.Replace("<PartnerURL>",
txtPartnerURL.Text);
fields.SetField("formText", formText);
// Get content to make changes
PdfContentByte overContent = stamp.GetOverContent(1);
// Add logo image
iTextSharp.text.Image logo =
iTextSharp.text.Image.GetInstance(Server.MapPath("~/logo.jpg"));
float[] logoArea = fields.GetFieldPositions("Logo");
iTextSharp.text.Rectangle logoRect = new
Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]);
// right alignment
logo.ScaleToFit(logoRect.Width, logoRect.Height);
logo.SetAbsolutePosition(logoArea[3] - logo.ScaledWidth +
(logoRect.Width - logo.ScaledWidth) / 2,
logoArea[2] + (logoRect.Height - logo.ScaledHeight)
/ 2);
overContent.AddImage(logo);
// Add Signature
iTextSharp.text.Image signature =
iTextSharp.text.Image.GetInstance(Server.MapPath("~/signature.jpg"));
float[] signArea = fields.GetFieldPositions("Signature");
iTextSharp.text.Rectangle signRect = new
Rectangle(signArea[1], signArea[2], signArea[3], signArea[4]);
signature.ScaleToFit(signRect.Width, signRect.Height);
signature.SetAbsolutePosition(signArea[1] + (signRect.Width
- signature.ScaledWidth) / 2,
signArea[2] + (signRect.Height -
signature.ScaledHeight) / 2);
overContent.AddImage(signature);
// Add barcode
Barcode39 code39 = new Barcode39();
code39.Code = txtAppID.Text;
code39.StartStopText = false;
iTextSharp.text.Image image39 =
code39.CreateImageWithBarcode(overContent, null, null);
float[] barcodeArea =
fields.GetFieldPositions("AppIDBarCode");
iTextSharp.text.Rectangle rect = new
Rectangle(barcodeArea[1], barcodeArea[2], barcodeArea[3],
barcodeArea[4]);
image39.ScaleToFit(rect.Width, rect.Height);
image39.SetAbsolutePosition(barcodeArea[1] + (rect.Width -
image39.ScaledWidth) / 2,
barcodeArea[2] + (rect.Height -
image39.ScaledHeight) / 2);
overContent.AddImage(image39);
stamp.FormFlattening = false;
stamp.FreeTextFlattening = true;
stamp.Close();
}

If you could figure out where the problem is, that would be greatly
appreciated.
