Annotations

Use a PdfDocument object's AnnotationManager, along with the AnnotationOptions class from IronPDF, to add "sticky note"-style annotations to specified pages of a PDF document.

Create a text-based annotation at a given location on a page by specifying the text and the Cartesian (x, y) coordinates as arguments in an AnnotationOption constructor, as shown in the code example above. Next, invoke the addTextAnnotation method on the AnnotationManager to add the annotation to the desired page in the working PDF document.

Additional methods on every AnnotationOptions object enable developers to customize an annotation's appearance and behavior. In the above code example, we set its opacity and featured icon, as well as set it to not be editable or printable. Developers can also change the color, height, and title of an annotation, as well as its title, subject, content, and location.
