Sample program showing how to create a PDF using jPDFProcess. You first create a PDF, add a page to it then use the Graphics object form the page to draw onto it. On the page we draw text and an image. In this little snippet, the compression used for the image within the PDF document is set to JPEG2000. The same code can be used to add content to an existing page.
// create document PDFDocument pdfDoc = new PDFDocument (); // add a page PDFPage page = pdfDoc.appendNewPage(8.5 * 72, 11 * 72); // get graphics from the page // this object is a Graphics2D Object and you can draw anything // you would draw on a Graphics2D PDFGraphics g2d = (PDFGraphics) page.createGraphics(); // set image compression to JPEG2000 g2d.setImageCompression(new ImageCompression(ImageCompression.COMPRESSION_JPEG2000, 0.8f)); // load image BufferedImage myimage = ImageIO.read(new File("C:\\myfolder\\image.png")); // draw image on the graphics object of the page g2d.drawImage(myimage,5,5,null); // courier 12 font Font courierFont = PDFGraphics.COURIER.deriveFont(24f); g2d.setColor(Color.red); // draw text on the graphics object of the page page.drawText("NEW TEXT", courierFont, Color.BLUE, 494, 14, null); // Save the document pdfDoc.saveDocument ("C:\\myfolder\\out.pdf"); |
