Use PageAreaRedaction Leave feedback

You can use PageAreaRedaction to redact an area of a specific page range from sensitive data in text, images, and annotations. Combine it with PageRangeFilter and PageAreaFilter on ReplacementOptions. This works for PDF and for other formats that support page filters (see Supported document formats). For embedded or standalone images, area coordinates follow the page (or visible) placement of the image.

The following example demonstrates how to apply PageAreaRedaction to the right half of the last page in a PDF document.

const redaction = require('@groupdocs/groupdocs.redaction');
const java = require('java');
const Color = java.import('java.awt.Color');
const Dimension = java.import('java.awt.Dimension');
const Point = java.import('java.awt.Point');

const redactor = new redaction.Redactor('Sample.pdf');
        try 
        {
const rx = java.util.regex.Pattern.compile('urna');
const optionsText = new redaction.ReplacementOptions('[redarea]');
            optionsText.setFilters(new redaction.RedactionFilter[] {
                new redaction.PageRangeFilter(redaction.PageSeekOrigin.End, 0, 1), // last page
                new redaction.PageAreaFilter(new Point(300, 0), new Dimension(300, 840)) // right half of the page
            });
const optionsImg = new redaction.RegionReplacementOptions(Color.RED, new Dimension(100, 100));
const result = redactor.apply(new redaction.PageAreaRedaction(rx, optionsText, optionsImg));
            if (result.getStatus() !== redaction.RedactionStatus.Failed)
            {
                redactor.save();
            }                            
        }
        finally {
  redactor.close();
}
