Usage

The following example demonstrates how to apply an ImageAreaRedaction to all embedded images within a PDF document.

C#

using (Redactor redactor = new Redactor("D:\\test_with_embedded_images.pdf"))
{
   System.Drawing.Point samplePoint = new System.Drawing.Point(516, 311);
   System.Drawing.Size sampleSize = new System.Drawing.Size(170, 35);
   RedactorChangeLog result = redactor.Apply(new ImageAreaRedaction(samplePoint,
                new RegionReplacementOptions(System.Drawing.Color.Blue, sampleSize)));
   if (result.Status != RedactionStatus.Failed)
   {
      redactor.Save();
   };
}

The following example demonstrates how to create a rasterized PDF from a Microsoft Word document and apply image redactions to its pages

C#

var stream = new MemoryStream();
// Rasterize the document before applying redactions
using (var redactor = new Redactor("C:\\Temp\\sample.docx"))
{
    // Perform annotation and textual redactions, if needed
    redactor.Save(stream, new RasterizationOptions() { Enabled = true });
    stream.Seek(0, SeekOrigin.Begin);
}
// Re-open the rasterized PDF document to redact its pages as images
using (var redactor = new Redactor(stream))
{
    RedactorChangeLog result = redactor.Apply(new Redactions.ImageAreaRedaction(new System.Drawing.Point(1160, 2375),
        new RegionReplacementOptions(System.Drawing.Color.Aqua, new System.Drawing.Size(1050, 720))));
    if (result.Status != RedactionStatus.Failed)
    {
        using (var fileStream = File.OpenWrite("C:\\Temp\\sample_docx_Raster.pdf"))
        {
            redactor.Save(fileStream, new RasterizationOptions() { Enabled = false });
        }
    }
}
