This prevents the need, for user to modify the pdf form fields. For any data which needs to be modified, I do it in the web page and then save the modified data/results to a pdf file. It’s easy to work with PDFs, when we have a basic template (created externally using Adobe/OpenOffice) in place, - instead of generating a new PDF from scratch. In most of the examples below, I tried to alter,copy a template PDF and then save it into a brand new output PDF file. Import .ITextSharp is open source PDF solution. #Pdfwriter example code#Save this code in a file with name AddingImage.java. It creates a PDF document with the name addingImage.pdf, adds an image to it, and saves it in the path C:/itextExamples/. #Pdfwriter example how to#The following Java program demonstrates how to add an image to a PDF document using the iText library. While instantiating, pass the above created ImageData object as a parameter to its constructor, as shown below.Īdd the image object created in the previous step using the add() method of the Document class, as shown below.Ĭlose the document using the close() method of the Document class, as shown below. Now, instantiate the Image class of the package. ImageData data = ImageDataFactory.create(imageFile) String imageFile = "C:/itextExamples/javafxLogo.jpg" As a parameter of this method, pass a string parameter representing the path of the image, as shown below. To create the image object, first of all, create an ImageData object using the create() method of the ImageDataFactory class. Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below. ![]() One of the constructors of this class accepts an object of the class PdfDocument. The Document class of the package is the root element while creating a self-sufficient PDF. 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. ![]() PdfDocument pdfDoc = new PdfDocument(writer) Instantiate the PdfDocument class by passing the above created PdfWriter object to its constructor, as shown below. To instantiate this class (in writing mode), you need to pass an object of the class PdfWriter to its constructor. ![]() The PdfDocument class is the class that represents the PDF Document in iText. When an object of this type is passed to a PdfDocument (class), every element added to this document will be written to the file specified. String dest = "C:/itextExamples/addingImage.pdf" 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. The constructor of this class accepts a string, representing the path of the file where the PDF is to be created. The PdfWriter class represents the DocWriter for a PDF. 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.įollowing are the steps to add an image to the PDF document. While instantiating this class, you need to pass a PdfDocument object as a parameter, to its constructor. You can create an empty PDF Document by instantiating the Document class. In this chapter, we will see how to add an image to a PDF document using the iText library. ![]()
