Add strikeout annotation

Strikeout annotation marks text fragment with a strikethrough styling like shown at the picture below.

There is an ability to specify the next fields for StrikeoutAnnotation type:

  • FontColor - color of annotation text;
  • Opacity - allows to set annotation opacity;
  • Points - annotation positions set by array of points.

Follow these steps to add Strikeout annotation to document:

  • Instantiate Annotator object with input document path or stream;
  • Instantiate StrikeoutAnnotation object with desired properties (position, page number, etc);
  • Call add method and pass StrikeoutAnnotation object;
  • Call save method with resultant document path or stream.

The following code demonstrates how to add StrikeoutAnnotation to the document:

String outputPath = Constants.getOutputFilePath("AddTextStrikeoutAnnotation", FilenameUtils.getExtension(Constants.INPUT));
            final Annotator annotator = new Annotator(Constants.INPUT);
            try {
                Reply reply1 = new Reply();
                reply1.setComment("First comment");
                reply1.setRepliedOn(Calendar.getInstance().getTime());
                Reply reply2 = new Reply();
                reply2.setComment("Second comment");
                reply2.setRepliedOn(Calendar.getInstance().getTime());
                java.util.List<Reply> replies =  new ArrayList<Reply>();
                replies.add(reply1);
                replies.add(reply2);
                Point point1 = new Point(80, 730);
                Point point2 = new Point(240, 730);
                Point point3 = new Point(80, 650);
                Point point4 = new Point(240, 650);
                List<Point> points = new ArrayList<Point>();
                points.add(point1);
                points.add(point2);
                points.add(point3);
                points.add(point4);
                StrikeoutAnnotation strikeout = new StrikeoutAnnotation();
                strikeout.setCreatedOn(Calendar.getInstance().getTime());
                strikeout.setFontColor(65535);
                strikeout.setMessage("This is strikeout annotation");
                strikeout.setOpacity(0.7);
                strikeout.setPageNumber(0);
                strikeout.setPoints(points);
                strikeout.setReplies(replies);
                annotator.add(strikeout);
                annotator.save(outputPath);
            } finally {
                if (annotator != null) {
                    annotator.dispose();
                }
            }
