To add an image to the pdf, create and an object of the image that is required to be added and add it using the add method of the Document class. You can insert the image in a desired position on the document using the method setFixedPosition of the Image class.

This class belongs to the package com.

The constructor of this class accepts a string, representing the path of the file where the PDF is to be created. Instantiate the PdfWriter class by passing a string value representing the path where you need to create a PDF to its constructor, as shown below.

When an object of this type is passed to a PdfDocument classevery element added to this document will be written to the file specified. To instantiate this class in writing modeyou need to pass an object of the class PdfWriter to its constructor.

Instantiate the PdfDocument class by passing the above created PdfWriter object to its constructor, as shown below. Once a PdfDocument object is created, you can add various elements like page, font, file attachment, and event handler using the respective methods provided by its class. The Document class of the package com. One of the constructors of this class accepts an object of the class PdfDocument. Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

To create the image object, first of all, create an ImageData object using the create method of the ImageDataFactory class. As a parameter of this method, pass a string parameter representing the path of the image, as shown below.

Now, instantiate the Image class of the com. While instantiating, pass the ImageData object as a parameter to its constructor, as shown below. Set the position of the image to the coordinateson the document using this method, as shown below. Now, add the image object, created in the previous step, using the add method of the Document class, as shown below. The following Java program demonstrates how to set an image at a desired position on a PDF document using the iText library.

Previous Page. Next Page. Previous Page Print Page.The seventh article in my iTextSharp series looks at working with images. This article builds on the previous six which are listed below. There are a number of ways to create images with iTextSharp using the Image.

GetInstance method. Probably the most used option will be to pass a filesystem path and file name into the method:. MapPath "PDFs". MapPath "Images". Create. Add new Paragraph "GIF". Alternative constructors that you may use include passing a URL or a System.

Image object as opposed to an iTextSharp. Note - the following snippet that System. FromStream method shows the use of namespace aliasing again sd.

Add new Paragraph "PNG". GetInstance sd. FromStream fsImageFormat. Png. It's difficult to tell from the images I have provided so far, but the resolution of the resulting images in the PDF file is not that great.

By default, images are embedded at 72 dpi Dots Per Inch which coincidentally, matches the number of points in an inch. If this file was being prepared for printing, the final job would be a bit nasty. Generally, commercial printers require that colour images for printing have a resolution of dpi. What you are actually trying to do is squeeze pixels into the space that 72 normally occupies. The image stays the same in terms of file size but occupies less space in the document.

Now, I have a large tif file that I want to use as a logo on an A4 letterhead. It measures x pixels. So at the default 72 dpi, it will measure 4.

Increasing the resolution to dpi will reduce the width to 1 inch, and the depth to 2.Last post May 12, AM by popopol. This works just fine. Now I have an additional thing I need to do. I need to insert an image into the PDF file at a specific point.

Doing absolute positioning is not a problem. GetInstance chartLoc ; chartImg. SetAbsolutePosition 50. GetInstance Server. I use this and it works for sure. Do you mean that you get no errors when you create the document and the problem occurs when you have to write on a completed doc? I haven't a table as this isn't a new document but a template that I use. I was playing with:. Writer ; cB. AddImage chartImg. Kept on giving me the error "object not set to a reference" on the addImage.

I manage to create a PDF from a template and add some text on top of it before I try to add the image in.

Module is optimized and the debugger option 'Just My Code' is enabled.This article will review the basics of programmatically inserting and positioning an image in a PDF being generated using the iTextSharp library.

In the example of adding a logo from the Images folder from the root of your Web site to your PDF, this is done as follows:.

As you can see this is quite straightforward. Next you will want to add your image to your PDF document.

I am not aware of being able to refer to an image multiple times in a PDF without actually including a new physical copy. Wow, I did not such a quick reply!

In the first part we looked at how to create the file and add meta information.

We also added a simple line of text in the document. As there are several ways of placing elements in the document, I will describe two in this article; The flow layout and exact positioning. Flow layout. The last position is here the Y: The second loop creates the left to right "column" illustration, and that one goes from right to left as normal positioning of coordinates are used.

This is normally something I keep in printing on my desktop when I design PDF's using iTextSharp, it can otherwise be many test documents created before everything falls into the right place! Text alignment. View All. Micke Blomqvist Updated date, Apr 05 Flow layout The flow layout mode just puts all of the added elements in a left to right, line by line manner.

This was how we put Hello World to the document in part I. When you write text like this you don't need to keep track of the page breaks, this is handled by the document itself. Exact positioning. Here you need to control the page bounds yourself, keeping track of when it's time to switch page.

This gives us better control over how we create documents. To enable exact positioning of text and other elements as described above you need to use the PdfContentByte class which enables you to place it where you want to. You get hold of a reference with this simple line of code:. One tricky thing to keep track of is that the y coordinate in the SetTextMatrix are a bit different from normal use of graphic coordinates, it works from the top bottom of the document, is backward.

To visualize this, let's do two simple for loops to draw the positions in the document. You can align the text by using the ShowTextAligned method which takes an alignment parameter, like this:. To draw a line with exact positioning you need to first set the line width, like this: cb.

SetLineWidth 0f. Then you set the starting point, like this: cb. MoveTo 30, and the ending point, like this: cb.While instantiating this class, you need to pass a PdfDocument object as a parameter to its constructor.

To add image to the PDF, create an object of the image that is required to be added and add it using the add method of the Document class. You can scale an image using the setAutoScale method.
