Add text redaction annotation
Text redaction annotation fills part of text with black rectangle (used if you want to hide some text) like shown at the picture below.
There is an ability to specify the next fields for TextRedactionAnnotation type
- Points - annotation positions set by array of points.
Follow these steps to add TextRedaction annotation to document:
- Instantiate Annotator object with input document path or stream;
- Instantiate TextRedactionAnnotation object with desired properties (position, page number, etc);
- Call add method and pass TextRedactionAnnotation object;
- Call save method with resultant document path or stream.
The following code demonstrates how to add TextRedactionAnnotation 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);
TextRedactionAnnotation textRedaction = new TextRedactionAnnotation();
textRedaction.setCreatedOn(Calendar.getInstance().getTime());
textRedaction.setMessage("This is text redaction annotation");
textRedaction.setPageNumber(0);
textRedaction.setPoints(points);
textRedaction.setReplies(replies);
annotator.add(textRedaction);
annotator.save(outputPath);
} finally {
if (annotator != null) {
annotator.dispose();
}
}
