Main.java:26 : BufferedImage image = firstPage.convertToImage();

Is there any possibility to get first page as image by using PDFBox?

Full code:

try {
            String sourceDir = "/home/linux/Downloads/test.pdf";
            String destinationDir = "/home/linux/Downloads/testImage";
            File sourceFile = new File(sourceDir);
            File destinationFile = new File(destinationDir);

                PDDocument document = PDDocument.load(sourceDir);
                PDPage firstPage = (PDPage) document.getDocumentCatalog().getAllPages().get(1);

                String fileName = sourceFile.getName().replace(".pdf", "");

                    BufferedImage image = firstPage.convertToImage();
                    ImageIO.write(image , "jpg", new File(destinationDir +fileName+"_"+".jpg"));

                document.close();

        } catch (Exception e) {
                    e.printStackTrace();
}

I just need to parse first page as image.
