public static void addTextHighlightAnnotation(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        HighlightAnnotation highlightAnnotation = new HighlightAnnotation(
                document.getPages().get_Item(1), new Rectangle(300, 750, 320, 770, true));
        document.getPages().get_Item(1).getAnnotations().add(highlightAnnotation);
        document.save(outputFile.toString());
    }
}

public static void addTextUnderlineAnnotation(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        UnderlineAnnotation underlineAnnotation = new UnderlineAnnotation(
                document.getPages().get_Item(1), new Rectangle(299.988, 713.664, 308.708, 720.769, true));
        underlineAnnotation.setTitle("Aspose User");
        underlineAnnotation.setSubject("Inserted Underline 1");
        underlineAnnotation.setFlags(AnnotationFlags.Print);
        underlineAnnotation.setColor(Color.getBlue());
        document.getPages().get_Item(1).getAnnotations().add(underlineAnnotation);
        document.save(outputFile.toString());
    }
