Usage

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

C#

            using (Redactor redactor = new Redactor("Sample.pdf"))
            {
                // Get the actual size information for the last page:
                IDocumentInfo info = redactor.GetDocumentInfo();
                PageInfo lastPage = info.Pages[info.PageCount - 1];
                ReplacementOptions options = new Redactions.ReplacementOptions("[secret]");
                options.Filters = new RedactionFilter[] { 
                    new PageRangeFilter(PageSeekOrigin.End, 0, 1),
                    new PageAreaFilter(new System.Drawing.Point(0, lastPage.Height/2), 
                        new System.Drawing.Size(lastPage.Width, lastPage.Height / 2))
                };
                RedactorChangeLog result = redactor.Apply(new ExactPhraseRedaction("dolor", options));
                if (result.Status != RedactionStatus.Failed)
                {
                    redactor.Save();
                };
            }
