public static void main(String[] args) {
            String html = "<html lang=\"en\" xmlns=\http://www.w3.org/1999/xhtml\ style=\"cursor: default;\">"
                        + "<body id=\"body\" class=\"modal-open\" style=\"cursor: default; padding-right: 15px;\">\r\n"

            HtmlImageGenerator imageGenerator = new HtmlImageGenerator();
            imageGenerator.loadHtml(html);
            BufferedImage bimg = imageGenerator.getBufferedImage();
            float width = bimg.getWidth();
            float height = bimg.getHeight();
            PDPage page = new PDPage(new PDRectangle(width, height));
            PDDocument document = new PDDocument();
            document.addPage(page);
            try {
                  PDImageXObject pdImage = LosslessFactory.createFromImage(document, bimg);

                  try (PDPageContentStream contentStream = new PDPageContentStream(document, page, AppendMode.OVERWRITE, true,
                              true)) {
                        contentStream.drawImage(pdImage, 0, 0, width, height);
                  }
                  document.save("xx.pdf");
                  document.close();
