I
wrote series of articles about create PDF document in ASP.NET with C# using
iTextSharp. In this article I’m going to explain how to align images in PDF
document. Other articles related to

Here
I’m going to explain how to use image in PDF document using iTextSharp. First we have to download
iTextSharp.dll class library and include to our project.
You can download iTextSharp.dll class
library here
http://sourceforge.net/projects/itextsharp/
Then open your project and include
that iTextSharp.dll class library.
Browse the iTextSharp.dll file which
is downloaded now and click ok.
iTextSharp allows you to use images in
PDF document and it’ll support many image formats like .jpg, .jpeg, .png, .bmp,
.tif and .wmf.
Image.GetInstance method is used to create images in
PDF document.
iTextSharp.text.Image
gif = iTextSharp.text.Image.GetInstance(imagepath
+
"/image.jpg");
iTextSharp
provides way for align images in PDF document. There are some properties used
to do that.
Sample code:
gif.ScaleToFit(250f, 250f);
gif.Alignment
= iTextSharp.text.Image.TEXTWRAP |
iTextSharp.text.Image.ALIGN_RIGHT;
gif.IndentationLeft = 9f;
gif.SpacingAfter = 9f;
gif.BorderWidthTop = 36f;
You can create your designer page now
Designer source code:
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD
XHTML 1.0 Transitional//EN"

</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnShow"
runat="server"
Text="Show
PDF"
OnClick="btnShow_OnClick"/>
</div>
</form>
</body>
</html>
Here
you should use following namespaces and create one folder for store PDF
documents
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

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

{
protected void
Page_Load(object sender, EventArgs e)
{
}

Button1_Click(object sender, EventArgs e)
{
//server folder path which is stored your PDF documents
string path = Server.MapPath("PDF-Files");
string imagepath = Server.MapPath("Images");
string filename = path + "/Doc1.pdf";
//Create new PDF document
Document document = new
Document(PageSize.A4,
20f, 20f, 20f, 20f);
try
{
PdfWriter.GetInstance(document, new FileStream(filename,
FileMode.Create));
//Create object for image
iTextSharp.text.Image gif =
iTextSharp.text.Image.GetInstance(imagepath
+ "/image.jpg");
Paragraph paragraph = new

paragraph.Alignment = Element.ALIGN_JUSTIFIED;

document.Add(new Paragraph(paragraph));
}
catch (Exception

{
}
finally
{
document.Close();
ShowPdf(filename);
}
}
public void ShowPdf(string filename)
{
