Text Based Annotations using Java

Add a text annotation

1. Open the input PDF and target the page where the text annotation should be placed.
2. Create the TextAnnotation, define its rectangle, and set its title, subject, flags, and color.
3. Add the annotation to the page and save the updated document.

public static void textAnnotationAdd(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        TextAnnotation textAnnotation = new TextAnnotation(
                document.getPages().get_Item(1), new Rectangle(299.988, 613.664, 428.708, 680.769, true));
        textAnnotation.setTitle("Aspose User");
        textAnnotation.setSubject("Inserted text 1");
        textAnnotation.setFlags(AnnotationFlags.Print);
        textAnnotation.setColor(Color.getBlue());

        document.getPages().get_Item(1).getAnnotations().add(textAnnotation, false);
        document.save(outputFile.toString());
    }
}

Add a free text annotation

1. Load the source PDF and select the target page and rectangle for the free text note.
2. Create the FreeTextAnnotation, initialize its default appearance, and set the title and color.
3. Add the annotation to the page and save the result.

public static void freeTextAnnotationAdd(Path inputFile, Path outputFile) {
    try (Document document = new Document(inputFile.toString())) {
        FreeTextAnnotation freeTextAnnotation = new FreeTextAnnotation(
                document.getPages().get_Item(1),
                new Rectangle(299, 713, 308, 720, true),
                new DefaultAppearance());
        freeTextAnnotation.setTitle("Aspose User");
        freeTextAnnotation.setColor(Color.getLightGreen());

        document.getPages().get_Item(1).getAnnotations().add(freeTextAnnotation);
        document.save(outputFile.toString());
    }
}
