        var page = document.getPages().get_Item(1);
        var textFragment = findTextFragment(page, "REPORT");

        var annotation = new RedactionAnnotation(page, textFragment.getRectangle());

        var quadPoints = getTextFragmentQuadPoints(textFragment);
        annotation.setQuadPoints(quadPoints); //when setting this field - the text under the annotation was not removed


    private TextFragment findTextFragment(Page page, String searchValue) {
        var absorber = new TextFragmentAbsorber(searchValue);


        return absorber.getTextFragments().get_Item(1);

    private Point[] getTextFragmentQuadPoints(TextFragment textFragment) {
        int offset = 0;
        var quadPoints = new Point[textFragment.getSegments().size() * 4];
        for (var segment : textFragment.getSegments()) {
            var rectangle = segment.getRectangle();
            quadPoints[offset] = new Point(rectangle.getLLX(), rectangle.getURY());
            quadPoints[offset + 1] = new Point(rectangle.getURX(), rectangle.getURY());
            quadPoints[offset + 2] = new Point(rectangle.getLLX(), rectangle.getLLY());
            quadPoints[offset + 3] = new Point(rectangle.getURX(), rectangle.getLLY());
