iText - Quick Guide

iText - Overview

The Portable Document Format (PDF) is a file format that helps to present data in a manner that is independent of application software, hardware, and operating systems. Each PDF file holds description of a fixed-layout flat document, including text, fonts, graphics, and other information needed to display it.

There are several libraries available to create and manipulate PDF documents through programs, such as −

Adobe PDF Library − This library provides API in languages such as C++, .NET and Java. Using this, we can edit, view, print, and extract text from PDF documents.
Formatting Objects Processor − Open-source print formatter driven by XSL Formatting Objects and an output independent formatter. The primary output target is PDF.
PDF Box − Apache PDFBox is an open-source Java library that supports the development and conversion of PDF documents. Using this library, you can develop Java programs that create, convert and manipulate PDF documents.
Jasper Reports − This is a Java reporting tool which generates reports in PDF document including Microsoft Excel, RTF, ODT, comma-separated values and XML files.

What is iText?

Similar to above listed software's iText is a Java PDF library using which, you can develop Java programs that create, convert, and manipulate PDF documents.

Features of iText

Following are the notable features of iText library −

Interactive − iText provides you classes (API's) to generate interactive PDF documents. Using these, you can create maps and books.
Adding bookmarks, page numbers, etc − Using iText, you can add bookmarks, page numbers, and watermarks.
Split & Merge − Using iText, you can split an existing PDF into multiple PDFs and also add/concatenate additional pages to it.
Fill Forms − Using iText, you can fill interactive forms in a PDF document.
Save as Image − Using iText, you can save PDFs as image files, such as PNG or JPEG.
Canvas − iText library provides you a Canvas class using which you can draw various geometrical shapes on a PDF document like circle, line, etc.
Create PDFs − Using iText, you can create a new PDF file from your Java programs. You can include images and fonts too.

IText Environment

Follow the steps given below to set the iText environment on Eclipse.

Step 1 − Install Eclipse and open a new project in it as shown below.

Step 2 − Create an iTextSample project as shown below.

iText - Creating a PDF Document

Let us now understand how to create a PDF document using the iText library.

Creating an Empty PDF Document

You can create an empty PDF Document by instantiating the Document class. While instantiating this class, you need to pass a PdfDocument object as a parameter to its constructor.

Following are the steps to create an empty PDF document.

Step 1: Creating a PdfWriter object

The PdfWriter class represents the Doc Writer for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter 
String dest = "C:/itextExamples/sample.pdf"; 
PdfWriter writer = new PdfWriter(dest);

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.

Step 2: Creating a PdfDocument object

The PdfDocument class is the class that represents the PDF Document in iText. This class belongs to the package com.itextpdf.kernel.pdf. To instantiate this class (in writing mode), you 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.

// Creating a PdfDocument  
PdfDocument pdfDoc = new PdfDocument(writer);

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.

Step 3: Adding an empty page

The addNewPage() method of the PdfDocument class is used to create an empty page in the PDF document.

Add an empty page to the PDF document created in the previous step as shown below.

// Adding an empty page 
pdfDoc.addNewPage();

Step 4: Creating a Document object

The Document class of the package com.itextpdf.layout is the root element while creating a self-sufficient PDF. 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.

// Creating a Document   
Document document = new Document(pdfDoc);

Step 5: Closing the Document

Close the document using the close() method of the Document class as shown below.

// Closing the document 
document.close();

Example

Following is the Java program which demonstrates the creation of a PDF Document. It creates a PDF document with the name sample.pdf, adds an empty page to it, and saves it in the path C:/itextExamples/

Save this code in a file with the name create_PDF.java.

import com.itextpdf.kernel.pdf.PdfDocument; 
import com.itextpdf.kernel.pdf.PdfWriter; 
import com.itextpdf.layout.Document;  

public class create_PDF {    
   public static void main(String args[]) throws Exception {              
      // Creating a PdfWriter       
      String dest = "C:/itextExamples/sample.pdf";       
      PdfWriter writer = new PdfWriter(dest); 
   
      // Creating a PdfDocument       
      PdfDocument pdfDoc = new PdfDocument(writer);              
   
      // Adding a new page 
      pdfDoc.addNewPage();               
   
      // Creating a Document        
      Document document = new Document(pdfDoc);               
   
      // Closing the document    
      document.close();              
      System.out.println("PDF Created");    
   } 
}

Compile and execute the saved Java file from the Command prompt using the following commands −

javac create_PDF.java 
java create_PDF

Upon execution, the above program creates a PDF document, displaying the following message.

PDF created

If you verify the specified path, you can find the created PDF document as shown below.

Since this is an empty document, if you try to open this document, it will display an error message, as shown in the following screenshot.

iText - Adding an AreaBreak

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.

Step 3: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

// Creating a Document   
Document document = new Document(pdfDoc);

Step 4: Creating a Table object

The Table class represents a two-dimensional grid filled with cells ordered in rows and columns. It belongs to the package com.itextpdf.layout.element.

Instantiate the Table class as shown below.

// Creating a table object 
float [] pointColumnWidths = {150F, 150F, 150F}; 
Table table = new Table(pointColumnWidths);

Step 5: Adding cells to the table

Create a cell object by instantiating the Cell class of the package com.itextpdf.layout.element. Add the contents of the cell using the add() method of this class.

Finally, to add this cell to the table, call the addCell() method of the Table class and pass the cell object as a parameter to this method, as shown below.

// Adding cell 1 to the table 
Cell cell1 = new Cell();   // Creating a cell 
cell1.add("Name");         // Adding content to the cell 
table.addCell(cell1);      // Adding cell to the table       

// Adding cell 2 to the table Cell 
cell2 = new Cell();       // Creating a cell 
cell2.add("Raju");        // Adding content to the cell 
table.addCell(cell2);     // Adding cell to the table

Step 6: Adding table to the document

Add the table object created in the previous step using the add() method of the Document class as shown below.

// Adding list to the document 
document.add(table);

Step 7: Closing the Document

Close the document using the close() method of the Document class, as shown below.

// Closing the document

iText - Formatting Cell Contents

In this chapter, we will see how to create a PDF document and add a table and format the contents of a cell in the table using the iText library.

Formatting the Cells in a Table

You can create an empty PDF Document by instantiating the Document class. While instantiating this class, you need to pass a PdfDocument object as a parameter, to its constructor. Then, to add a table to the document, you need to instantiate the Table class and add this object to the document using the add() method. You can format the contents of a cell in a table using the methods of the Cell class.

Following are the steps to format the contents of a cell in a table.

Step 1: Creating a PdfWriter object

The PdfWriter class represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter 
String dest = "C:/itextExamples/addingBackground.pdf"; 
PdfWriter writer = new PdfWriter(dest);

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.

Step 2: Creating a PdfDocument object

The PdfDocument class is the class that represents the PDFDocument in iText. This class belongs to the package com.itextpdf.kernel.pdf. To instantiate this class (in writing mode), you 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.

// Creating a PdfDocument  
PdfDocument pdfDoc = new PdfDocument(writer);

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.

Step 3: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

// Creating a Document   
Document document = new Document(pdfDoc);

Step 4: Creating a Table object

The Table class represents a two-dimensional grid filled with cells, ordered in rows and columns. It belongs to the package com.itextpdf.layout.element.

Instantiate the Table class as shown below.

// Creating a table 
float [] pointColumnWidths = {200F, 200F}; 
Table table = new Table(pointColumnWidths);

Step 5: Creating cells

Create a cell object by instantiating the Cell class of the package com.itextpdf.layout.element. Add the contents of the cell using the add() method of the Cell class, as shown below.

// Adding cell 1 to the table 
Cell cell1 = new Cell();     // Creating a cell 
cell1.add("Name");           // Adding content to the cell       

// Adding cell 2 to the table 
Cell cell2 = new Cell();     // Creating a cell 
cell2.add("Raju");           // Adding content to the cell

Step 6: Adding Background to the cell

Once you created the cell and added contents to it, you can format the cell. For example, you can set its background, align the text inside the cell, change the text color, etc., using different methods of the cell class such as setBackgroundColor(), setBorder(), setTextAlignment().

You can set the background color, border, and text alignment to the cell created in the previous step, as shown below.

c1.setBackgroundColor(Color.DARK_GRAY);    // Setting background color to cell1 
c1.setBorder(Border.NO_BORDER);            // Setting border to cell1 
c1.setTextAlignment(TextAlignment.CENTER); // Setting text alignment to cell1

Step 7: Adding cell to the table

Finally, to add this cell to the table, call the addCell() method of the Table class and pass the cell object as a parameter to this method, as shown below.

table.addCell(c1);

Step 8: Adding table to the document

Add the table object created in the previous step using the add() method of the Document class as shown below.

// Adding list to the document 
document.add(table);

Step 9: Closing the Document

Close the document using the close() method of the Document class, as shown below.

// Closing the document 
document.close();

iText - Formatting the Borders of a Cell

In this chapter, we will see how to format the borders of a cell in a table using iText library.

Formatting the Borders of a Cell

You can create an empty PDF Document by instantiating the Document class. While instantiating this class, you need to pass a PdfDocument object as a parameter to its constructor.

Then, to add a table to the document, you need to instantiate the Table class and add this object to the document using the add() method.

You can add various types of borders like DashedBorder, SolidBorder, DottedBorder, DoubleBorder, RoundDotsBorder, etc. with various colors using the setBorder() method of the Cell class.

Following are the steps to format the borders of a cell in a table.

Step 1: Creating a PdfWriter object

The PdfWriter class represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter 
String dest = "C:/itextExamples/coloredBorders.pdf"; 
PdfWriter writer = new PdfWriter(dest);

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.

Step 2: Creating a PdfDocument object

The PdfDocument class is the class that represents the PDFDocument in iText. This class belongs to the package com.itextpdf.kernel.pdf. To instantiate this class (in writing mode), you 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.

// Creating a PdfDocument  
PdfDocument pdfDoc = new PdfDocument(writer);

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.

Step 3: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

// Creating a Document  
Document document = new Document(pdfDoc);

Step 4: Creating a Table object

The Table class represents a two-dimensional grid filled with cells ordered in rows and columns. It belongs to the package com.itextpdf.layout.element.

Instantiate the Table class as shown below.

// Creating a table 
float [] pointColumnWidths = {200F, 200F}; 
Table table = new Table(pointColumnWidths);

Step 5: Creating cells

Create a cell object by instantiating the Cell class of the package com.itextpdf.layout.element add the contents of the cell using the add() method of the Cell class, as shown below.

// Adding cell 1 to the table 
Cell cell1 = new Cell(); // Creating a cell 
cell1.add("Name");       // Adding content to the cell

Step 6: Formatting the border of the cell

The iText library provides various classes representing the border such as DashedBorder, SolidBorder, DottedBorder, DoubleBorder, RoundDotsBorder, etc.

The constructors of these classes accept two parameters: a color object representing the color of the border and an integer representing the width of the border.

Choose one of this border types and instantiate the respective border by passing the color object and an integer representing the width, as shown below.

Border b1 = new DashedBorder(Color.RED, 3);

Now, set the border of the cell using the setBorder() method of the cell class. This method accepts an object of the type Border as a parameter.

Set the border of the cell by passing the above created Border object as a parameter to the setBorder() method as shown below.

c1.setBorder(b1)

Finally, to add this cell to the table, call the addCell() method of the Table class and pass the cell object as a parameter to this method, as shown below.

table.addCell(c1);

Step 7: Adding table to the document

Add the table object created in the previous step using the add() method of the Document class, as shown below.

// Adding list to the document 
document.add(table);

Step 8: Closing the Document

Close the document using the close() method of the Document class, as shown below.

iText - Nested Table

In this chapter, we will see how to add a nested table to a table in a PDF document using the iText library.

Adding Nested Tables in a Pdf

You can create an empty PDF Document by instantiating the Document class. While instantiating this class, you need to pass a PdfDocument object as a parameter, to its constructor. Then, to add a table to the document, you need to instantiate the Table class and add this object to the document using the add() method.

To add a table to this table, you need to create another table (nested table), and pass it to the cell object using the add() method of the Cell class.

Following are the steps to insert a table into the cell of a table.

Step 1: Creating a PdfWriter object

The PdfWriter class represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter 
String dest = "C:/itextExamples/addingNestedTable.pdf"; 
PdfWriter writer = new PdfWriter(dest);

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.

Step 2: Creating a PdfDocument object

The PdfDocument class is the class that represents the PDF Document in iText. This class belongs to the package com.itextpdf.kernel.pdf. To instantiate this class (in writing mode), you 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.

// Creating a PdfDocument  
PdfDocument pdfDoc = new PdfDocument(writer);

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.

Step 3: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

// Creating a Document   
Document document = new Document(pdfDoc);

Step 4: Creating a Table object

The Table class represents a two-dimensional grid filled with cells, ordered in rows and columns. It belongs to the package com.itextpdf.layout.element.

Instantiate the Table class as shown below.

// Creating a table 
float [] pointColumnWidths = {200F, 200F}; 
Table table = new Table(pointColumnWidths);

Step 5: Creating the cell

Create a cell object by instantiating the Cell class of the package com.itextpdf.layout, as shown below.

// Adding cell to the table 
Cell contact = new Cell();    // Creating a cell

Step 6: Creating Nested table

After creating the cell, create a nested table, and populate its cells, as shown below.

// Creating nested table for contact   
float [] pointColumnWidths2 = {150f, 150f}; 
Table nestedTable = new Table(pointColumnWidths2);    

// Populating row 1 and adding it to the nested table  
Cell nested1 = new Cell(); 
nested1.add("Phone"); 
nestedTable.addCell(nested1);       

Cell nested2 = new Cell(); 
nested2.add("9848022338"); 
nestedTable.addCell(nested2);  

// Populating row 2 and adding it to the nested table  
Cell nested3 = new Cell(); 
nested3.add("email"); 
nestedTable.addCell(nested3);

Cell nested4 = new Cell(); 
nested4.add("Raju123@gmail.com"); 
nestedTable.addCell(nested4);     

// Populating row 3 and adding it to the nested table  
Cell nested5 = new Cell(); 
nested5.add("Address"); 
nestedTable.addCell(nested5);  

Cell nested6 = new Cell(); 
nested6.add("Hyderabad"); 
nestedTable.addCell(nested6);

Step 7: Adding Nested table to the cell

Now, add the above created nested table to the cell of the parent (container) table using the add() method of the Cell class. And, add this cell to the parent table using the addCell() method of the Table class, as shown below.

contact.add(nestedTable); 
table.addCell(contact);

Step 8: Adding table to the document

Add the table object created in the previous step using the add() method of the Document class, as shown below.

// Adding list to the document 
document.add(table);

Step 9: Closing the Document

Close the document using the close() method of the Document class, as shown below.

// Closing the document 
document.close();

Example

The following Java program demonstrates how to add a table to a cell of a table (nested table) in a PDF document using the iText library.

Step 4: Creating a Table object

The Table class represents a two-dimensional grid filled with cells, ordered in rows and columns. It belongs to the package com.itextpdf.layout.element.

Instantiate the Table class as shown below.

// Creating a table 
float [] pointColumnWidths = {200F, 200F}; 
Table table = new Table(pointColumnWidths);

Step 5: Creating the cell

Create a cell object by instantiating the Cell class of the package com.itextpdf.layout, as shown below.

// Adding cell to the table 
Cell listCell = new Cell(); // Creating a cell

Step 6: Creating List object

After creating the cell, create a list object by instantiating the List class of the package com.itextpdf.layout.element. Create the list items by instantiating the ListItem class and add the created items using the add() method of the List class, as shown below.

List list = new List(); 
ListItem item1 = new ListItem("JavaFX"); 
ListItem item2 = new ListItem("Java"); 
ListItem item3 = new ListItem("Java Servlets");        
list.add(item1); 
list.add(item2); 
list.add(item3);

Step 7: Adding list to the cell of a table

Now, add the above created list to the cell of the table using the add() method of the Cell class. And, add this cell to the table using the addCell() method of the Table class, as shown below.

listCell.add(list); 
table.addCell(listCell);

Step 8: Adding table to the document

Add the table object created in the previous step using the add() method of the Document class, as shown below.

// Adding list to the document 
document.add(table);

Step 9: Closing the Document

Close the document using the close() method of the Document class, as shown below.

iText - Setting Position of the Image

In this chapter, we will see how to set the position of an image in a PDF document using the iText library.

Setting the Position of the Image

You can create an empty PDF Document by instantiating the Document class. While instantiating this class, you need to pass a PdfDocument object as a parameter to its constructor.

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.

Following are the steps to set the position of an image in the PDF document.

Step 1: Creating a PdfWriter object

The PdfWriter class represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter 
String dest = "C:/itextExamples/positionOfImage.pdf"; 
PdfWriter writer = new PdfWriter(dest);

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.

Step 2: Creating a PdfDocument object

Instantiate the PdfDocument class by passing the above created PdfWriter object to its constructor, as shown below.

// Creating a PdfDocument  
PdfDocument pdfDoc = new PdfDocument(writer);

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.

Step 3: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument created in the previous steps, as shown below.

// Creating a Document  
Document document = new Document(pdfDoc);

Step 4: Creating an Image object

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.

// Creating an ImageData object 
String imageFile = "C:/itextExamples/javafxLogo.jpg"; 
ImageData data = ImageDataFactory.create(imageFile);

Now, instantiate the Image class of the com.itextpdf.layout.element package. While instantiating, pass the ImageData object as a parameter to its constructor, as shown below.

// Creating an Image object 
Image img = new Image(data);

Step 5: Setting the position of the image

You can set the position of the image in a PDF document using the setFixedPosition() method of the Image. Set the position of the image to the coordinates (100, 250) on the document using this method, as shown below.

// Setting the position of the image to the center of the page 
image.setFixedPosition(100, 250);

Step 6: Adding image to the document

Now, add the image object, created in the previous step, using the add() method of the Document class, as shown below.

// Adding image to the document 
document.add(img);

Step 7: Closing the Document

Close the document using the close() method of the Document class, as shown below.

// Closing the document 
document.close();

iText - Shrinking the Content

In this chapter, we will see how to scale an image on a PDF document using the iText library.

Shrinking the Content in a PDF

Following are the steps to shrink the contents of a PDF page using iText library.

Step 1: Creating a PdfWriter and PdfReader object

The PdfWriter class represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. 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.

// Creating a PdfWriter object 
String dest = "C:/itextExamples/shrinking.pdf"; 
PdfWriter writer = new PdfWriter(dest);

To read data from an existing pdf, create a PdfReader object as shown below.

// Creating a PdfReader 
String src = "C:/itextExamples/pdfWithImage.pdf"; 
PdfReader reader = new PdfReader(src);

Step 2: Creating a PdfDocument object(s)

Create source and destination PDF documents by passing the PdfWriter and PdfReader objects to the constructors, as shown below.

// Creating a PdfDocument objects 
PdfDocument destpdf = new PdfDocument(writer);         
PdfDocument srcPdf = new PdfDocument(reader);

Step 3: Opening a page from the existing PDF

Get a page from the source PDF using the getPage() method of the PdfPage class. Using this object, get the size of the page of the source document, as shown below.

// Opening a page from the existing PDF 
PdfPage origPage = srcPdf.getPage(1);       

// Getting the page size 
Rectangle orig = origPage.getPageSizeWithRotation();

Step 4: Shrinking the contents of the source pdf

Using the getScaleInstance() method of the AffineTransform class, shrink the contents of a page of the source document, as shown below.

// Shrink original page content using transformation matrix 
AffineTransform transformationMatrix = AffineTransform.getScaleInstance(    
   page.getPageSize().getWidth()/ orig.getWidth()/2,    
   page.getPageSize().getHeight()/ orig.getHeight()/2);

Step 5: Copying the page

Concatenate the affine transform matrix, created in the previous step, to the matrix of the canvas object of the destination PDF document, as shown below.

// Concatenating the affine transform matrix to the current matrix 
PdfCanvas canvas = new PdfCanvas(page);       
canvas.concatMatrix(transformationMatrix);

Now, add the page copy to the canvas object of the destination PDF to the source document, as shown below.

// Add the object to the canvas 
PdfFormXObject pageCopy = origPage.copyAsFormXObject(destpdf); 
canvas.addXObject(pageCopy, 0, 0);

Step 6: Creating the Document object

Instantiate the Document class by passing the object of the class PdfDocument, as shown below.

// Creating a Document   
Document document = new Document(destpdf);

Step 7: Closing the Document

Close the document using the close() method of the Document class, as shown below.

// Closing the document 
document.close();
