 mvn clean instal 

Java API to Create and Modify New PDF Documents

Apache PDFBox allows programmers to generate a new PDF document from scratch. After creating the document, developers can save the document in the desired location. PDF is one of the most commonly used file formats nowadays. PDF documents are compatible across various platforms and represent a document independently of the hardware, operating system, and application software used to create it. PDFBox also facilitates developers to modify existing PDF documents. Developers can add new pages as well as text to existing page documents.

// Create a new PDF document
PDDocument document = new PDDocument();
// Save document
document.save("fileformat.pdf");
// Close document
document.close();

Splitting and Merging PDF Documents using Java Library

Apache PDFBox provides the capability to merge multiple PDF documents into a single PDF document. To merge multiple documents first you need to load existing PDF documents and then set a path to the destination file. After that developers can add all the source PDF files in the sequence they would like to find in the final merged PDF file. We can split the given PDF document into multiple PDF files. This Splitter class is used to split the given PDF document into several other separate documents.

// Initialize PDFMergerUtility object
PDFMergerUtility pdfMergerUtility = new PDFMergerUtility();
// Set output file path
pdfMergerUtility.setDestinationFileName("merged.pdf");
// Add source documents
pdfMergerUtility.addSource(new File("document1.pdf"));
pdfMergerUtility.addSource(new File("document2.pdf"));
// Merger documents
pdfMergerUtility.mergeDocuments(MemoryUsageSetting.setupMainMemoryOnly());

Add and Extract Images to PDF Documents inside Java Apps

Apache PDFBox facilitates Java developers to insert images into an existing PDF document. Images always add real value to the piece of content. Images help us learn, grab attention, explain concepts and inspire. PDFBox provides a library for inserting an image into a PDF document. This library uses the Java program for inserting images in PDF documents. The API also enables developers to extract images from the existing PDF document and store it on the local disk.

// Create a new PDF document
PDDocument document = new PDDocument();
// Create a new page
PDPage page = new PDPage();
// Add page
document.addPage(page);
// Initialize PDImageXObject object
PDImageXObject pdImage = PDImageXObject.createFromFile("logo.png",document);
// Initialize PDPageContentStream object
PDPageContentStream contents = new PDPageContentStream(document, page);
// Drawing image
contents.drawImage(pdImage, 70, 250);
// Close contents
contents.close();
// save document
document.save("image.pdf");

Print PDF Documents in Various Ways using Java Library

Apache PDFBox enables Java developers to print a PDF document using the standard Java printing API. It allows developers to print PDF documents in various ways. Developers can now print the document at its actual size which is the recommended way to print. It supports printing with a print preview dialog as well as custom attributes. Developers can also print PDF documents using a custom page size and custom margins.

 import java.awt.print.PrinterException;

 import java.io.IOException;

 import org.apache.pdfbox.pdmodel.PDDocument;

 public class Print {

public static void main(String[] args) throws IOException, PrinterException
{
  PDDocument pdf=PDDocument.load("d:\\filename.pdf");
      pdf.print();
}

}
