Hi again,
I recently submitted the message below and received the listed reply. My question now is: What transparency cases are implemented by iText, and how do I create images that use them? Also, is there any way I can implement transparency cases myself, and where could I find some information on that? Thanks in advance for your help, and may I say iText is an impressive piece of programming.

It's not a bug. Not all the transparency cases are implemented for java.awt.Image.

Hello, I am having a probject with a transparent GIF. When I run the code listed below the image is displayed on the PDf with a gray background instead of a transparent background.
public static void main(String[] args) throws Exception {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("C:\\Test\\itext.pdf"));
document.open();
PdfContentByte cb = writer.getDirectContent(); cb.saveState(); cb.concatCTM(1, 0, 0, 1, 50, 400);
Graphics2D ig = cb.createGraphics(500, 500);
Image image = Toolkit.getDefaultToolkit().getImage("<<transparent image>>");
ig.drawImage(image, 50,50, null);
ig.dispose(); cb.restoreState();
document.close();
}
When I place the image in a JLabel using an ImageIcon, the image is transparent when displayed in a JFrame or printed. However, when I call the paint() method of the JLabel with the PDFGraphics2D, the image still has a gray background. Is this a bug, or am I doing something wrong? Please let me know what I can do.
Thank You, Alan Smoke
