Developers using GroupDocs.Redaction for .NET can leverage the latest features introduced in version 23.11 (DLLs-only package). This release expands the capabilities of the PageAreaRedaction class, empowering you to redact sensitive information within image formats and presentations.
PageAreaRedaction
With the latest .NET redaction API release, the PageAreaRedaction feature extends its support to include images and presentation documents. Users can easily redact images and presentations with this update for a more inclusive document redaction experience. Check out the following code example to learn how to redact a presentation document in C#.
using (Redactor redactor = new Redactor("Sample.pptx")) { Regex rx = new Regex("urna"); ReplacementOptions optionsText = new ReplacementOptions("[redarea]"); optionsText.Filters = new RedactionFilter[] { new PageRangeFilter(PageSeekOrigin.End, 0, 1), // last slide new PageAreaFilter(new System.Drawing.Point(0, 0), new System.Drawing.Size(300, 100)) }; RegionReplacementOptions optionsImg = new RegionReplacementOptions(System.Drawing.Color.Red, new System.Drawing.Size(100, 300)); // Redacted area will be an intersection, which is 100x100 RedactorChangeLog result = redactor.Apply(new PageAreaRedaction(rx, optionsText, optionsImg)); if (result.Status != RedactionStatus.Failed) { redactor.Save(); }; }
