To add images in PDF you need to give the image path to iTextSharp method.

Namespaces used in document:

 

using iTextSharp.text;

using iTextSharp.text.pdf;

using iTextSharp.text.html;

using iTextSharp.text.html.simpleparser;


string imageFilePath = Server.MapPath(".") + "images/Imagename.gif";

iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);

 

jpg.Alignment = Element.ALIGN_CENTER;

 

jpg.Alignment = Element.ALIGN_RIGHT;

 

For give the size to image

 

jpg.ScaleToFit(70, 40);

 

If you want to choose image as background then,

 

jpg.Alignment = iTextSharp.text.Image.UNDERLYING;

 

If you want to give absolute/specified fix position to image.

 

jpg.SetAbsolutePosition(7, 780);

 

It will show the image on Top of the page at left side.

 

For adding the paragraph we need to enter some more code.

 

 

Paragraph paragraph = newParagraph("For further information please contact:\nTest content");

 

It will show the information in two lines like given below:

For further information please contact:

Test content



\n is for new line in paragraph

 

Below we are giving the complete code for the information.

 

Response.ContentType = "application/pdf";

Response.AddHeader("content-disposition", "attachment;filename=nameofPDF.pdf");

 

Response.Cache.SetCacheability(HttpCacheability.NoCache);

StringWriter sw = newStringWriter();

HtmlTextWriter hw = newHtmlTextWriter(sw);

 

dlPressRelease.DataBind(); // datalist name will be here

dlPressRelease.RenderControl(hw);

 

string imageFilePath = Server.MapPath(".") + "images/Imagename.gif";

 

iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);

 

StringReader sr = newStringReader(sw.ToString());

 

// Page site and margin left, right, top, bottom is defined

Document pdfDoc = newDocument(PageSize.A4, 10f, 10f, 10f, 0f);

 

Paragraph paragraph = newParagraph("For further information please contact:\n\Test content");

 

//Resize image depend upon your need

jpg.ScaleToFit(70, 40);

 

jpg.SetAbsolutePosition(7, 780);

 

HTMLWorker htmlparser = newHTMLWorker(pdfDoc);

PdfWriter .GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();

 

pdfDoc.Add(jpg);

        

htmlparser.Parse(sr);

pdfDoc.Add(paragraph);

pdfDoc.Close();

Response.Write(pdfDoc);

Response.End();

 

 

There are some other options we can use according to our need while developing the application.

 

jpg.ScaleToFit(250f, 250f);

jpg.Border = Rectangle.BOX;

jpg.BorderColor = Color.YELLOW;

jpg.BorderWidth = 5f;

pdfDoc.Add(jpg);

pdfDoc.Add(newParagraph("Original Width: " + jpg.Width.ToString()));

pdfDoc.Add(newParagraph("Original Height " + jpg.Height.ToString()));

pdfDoc.Add(newParagraph("Scaled Width: " + jpg.ScaledWidth.ToString()));

pdfDoc.Add(newParagraph("Scaled Height " + jpg.ScaledHeight.ToString()));

float Resolution = jpg.Width / jpg.ScaledWidth * 72f;

pdfDoc.Add(newParagraph("Resolution: " + Resolution));

 

jpg.Rotation = (float)Math.PI / 2;

jpg.RotationDegrees = 90f;

 

It will rotate the image on specific angel.
