Hi,
I admit my question was not very clear. Sorry.
However, after heavy searching THE NET I found the solution to most of
my problems:
Document doc = new Document(PageSize.A4);
PdfWriter out = null;
try {
out = PdfWriter.getInstance(doc, new
FileOutputStream(getNewFilepath("C:/tmp/itexttest", "itextPDF") + ".pdf"));
} catch (IOException e) {
System.out.println("Exception opening pdf reader: " +
e.getLocalizedMessage());
return;
} catch (DocumentException e) {
System.out.println("Exception opening pdf reader: " +
e.getLocalizedMessage());
return;
}
doc.open();
// iText font != java.awt.Font !
FontFactory.registerDirectories(); // register all fonts in the
usual
directories
doc.addTitle("A PDF output test");
doc.addCreationDate();
doc.addCreator("M. Harig");
doc.addProducer();
Paragraph p = new Paragraph(" A PDF output test");
p.setAlignment(1);
doc.add(p);
///// print image
// print image title
p = new Paragraph("Image 1");
p.setAlignment(0);
doc.add(p);
JFrame frame = new JFrame("sdf");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel pnl = new JPanel();
pnl.add(new JButton("a button with a very long text"));
pnl.setPreferredSize(new Dimension(300,100));
frame.add(pnl);
frame.pack();
frame.setVisible(true);
// Because of a bug in IText (?), we have to set another LAF
// if we are using Substance LAF !!!!
// don't know if saving and restoring the old one is necessary
PanelUI old = pnl.getUI();
pnl.setUI((PanelUI)javax.swing.plaf.basic.BasicPanelUI.createUI(pnl));
BufferedImage img = new BufferedImage(pnl.getWidth(), pnl.getHeight(),
BufferedImage.TYPE_INT_ARGB);
Graphics2D img2D = img.createGraphics();
pnl.print(img2D);
float viewWidth = out.getPageSize().getWidth() - doc.leftMargin() -
doc.rightMargin();
double scaleX = viewWidth / pnl.getWidth();
img2D.scale(scaleX, scaleX); // keep aspect ratio
p = new Paragraph();
com.lowagie.text.Image itextImg =
com.lowagie.text.Image.getInstance(img, Color.BLUE, false);
p.add( itextImg );
doc.add( p );
// restore old LAF
pnl.setUI(old);
///// trailing text
doc.add(new Paragraph("Trailing text. This text should be printed below
the image."));
doc.close();

Michael
