public static void main() {
    String outputPath = "LoadDocumentFromFtp.pdf";
    String filePath = "sample.pdf";
    String server = "localhost";
    
	Annotator annotator = new Annotator(getFileFromFtp(server, filePath));
    
	AreaAnnotation area = new AreaAnnotation();
    area.setBox(new Rectangle(100, 100, 100, 100));
    area.setBackgroundColor(65535);

	annotator.add(area);
    annotator.save(outputPath);    
	annotator.dispose();
}

private static InputStream getFileFromFtp(String server, String filePath) throws IOException {
    FTPClient client = new FTPClient();
