Using C# to Add Watermark to All Images on a PDF Page

PdfLoadOptions loadOptions = new PdfLoadOptions();
// Constants.InDocumentPdf is an absolute or relative path to your document. Ex: @"C:\Docs\document.pdf"
using (Watermarker watermarker = new Watermarker(Constants.InDocumentPdf, loadOptions))
{
    // initialize image or text watermark
    TextWatermark watermark = new TextWatermark("Protected image", new Font("Arial", 8));
    watermark.HorizontalAlignment = HorizontalAlignment.Center;
    watermark.VerticalAlignment = VerticalAlignment.Center;
    watermark.RotateAngle = 45;
    watermark.SizingType = SizingType.ScaleToParentDimensions;
    watermark.ScaleFactor = 1;

    PdfContent pdfContent = watermarker.GetContent<PdfContent>();

    // get all images from the first page
    WatermarkableImageCollection images = pdfContent.Pages[0].FindImages();

    // add watermark to all found images
    foreach (WatermarkableImage image in images)
    {
        image.Add(watermark);
    }

    watermarker.Save(Constants.OutDocumentPdf);
}

Search Watermarks in PDF using Regular Expression via C# Code

// Constants.InDocumentPdf is an absolute or relative path to your document. Ex: @"C:\Docs\document.pdf"

{
    Regex regex = new Regex(@"^© \d{4}$");

    // search by regular expression

    // find possible watermarks using regular expression
    PossibleWatermarkCollection possibleWatermarks = watermarker.Search(textSearchCriteria);

    Console.WriteLine("Found {0} possible watermark(s).", possibleWatermarks.Count);
}
