The PDF Viewer component allows the process of programmatically adding or modifying annotations within a PDF document. With the ability to programmatically add any type of annotation using the AnnotationAdd API and edit existing annotations using the editAnnotation API, users can seamlessly enhance their PDF viewing experience.
The creation of an annotation when clicking the 'Add annotation' button is depending upon the selected properties from the Property panel. To update an existing annotation, users can select the desired annotation, modify its properties, and then click the 'Update' button.
