Delete Annotations (facades)

You can use PdfAnnotationEditor class to delete annotations, by a specified annotation type, from the existing PDF file. In order to do that you need to create a PdfAnnotationEditor object and bind input PDF file using bindPdf method. After that, call deleteAnnotations method, with the string parameter, to delete all the annotations from the file; the string parameter represents the annotation type to be deleted. Finally, use save method to save the updated PDF file.

The following code snippet shows you how to delete annotation by specified annotation type.

public static void DeleteAnnotation() {
        // Open document
        Scanner consoleScanner = new Scanner(System.in);
        Document document = new Document(_dataDir + "sample_cats_dogs.pdf");
        int index;
        for (index = 1; index <= document.getPages().get_Item(1).getAnnotations().size(); index++) {
            System.out.println(index + ". " + document.getPages().get_Item(1).getAnnotations().get_Item(index).getName()
                    + " " + document.getPages().get_Item(1).getAnnotations().get_Item(index).toString());
        }
        System.out.print("Please enter number:");
        index = consoleScanner.nextInt();

        PdfAnnotationEditor annotationEditor = new PdfAnnotationEditor();
        annotationEditor.bindPdf(document);
        annotationEditor.deleteAnnotation(document.getPages().get_Item(1).getAnnotations().get_Item(1).getName());

        // Save updated PDF
        annotationEditor.save(_dataDir + "DeleteAnnotation.pdf");
        consoleScanner.close();
    }
    ```
