Allow ImageAreaRedaction to be applied to rasterized PDF

This feature provides functionality to apply ImageAreaRedaction to any embedded image inside PDF document, including resterized PDF files.

Add support for embedded image redaction with Aspose.Words

This feature provides functionality to apply ImageAreaRedaction to any embedded image inside Microsoft Office Word or Open Office document.

Usage

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

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

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 });
        }
    }
}
