That's because you're supposed to buy and read the book so that the
author gets some financial rewards for his work. (He has to earn a
living too.)

OK, just for this once, I'll show the method I wrote to generate the PDF
that was sent in attachment in a previous mail.
public static void createPdf() throws IOException, DocumentException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(
document, new FileOutputStream("ballots.pdf"));
writer.setViewerPreferences(PdfWriter.PageModeUseThumbs);
PdfPageLabels pageLabels = new PdfPageLabels();
int dpiX, dpiY;
float imgWidthPica, imgHeightPica;
TreeSet<File> images = new TreeSet<File>();
for (int i = 0; i < FILES.length; i++) {
images.add(new File(FILES[i]));
}
String label;
for (File image: images) {
try {
Image img = Image.getInstance(image.getAbsolutePath());
dpiX = img.getDpiX();
if (dpiX == 0) {
dpiX = 72;
}
dpiY = img.getDpiY();
if (dpiY == 0) {
dpiY = 72;
}
imgWidthPica = (72 * img.getPlainWidth()) / dpiX;
imgHeightPica = (72 * img.getPlainHeight()) / dpiY;
img.scaleAbsolute(imgWidthPica, imgHeightPica);
document.setPageSize(new Rectangle(imgWidthPica, imgHeightPica));
if (document.isOpen()) {
document.newPage();
}
else {
document.open();
}
img.setAbsolutePosition(0, 0);
document.add(img);
label = image.getName();
if (label.lastIndexOf('.') > 0) {
label = label.substring(0, label.lastIndexOf('.'));
}
pageLabels.addPageLabel(
writer.getPageNumber(), PdfPageLabels.EMPTY, label);
}
catch (Exception e) {
System.err.println(e.getMessage());
}
}
if (document.isOpen()) {
writer.setPageLabels(pageLabels);
document.close();
}
}
If you don't like the opened Thumbnails panel, you can remove the line
that sets the viewer preferences. The same goes for the page labels.
This code shows the file name as a page label; maybe that's overkill in
your application.
