string inputFilePath = "Input.pdf";
string outputFilePath = "Output.pdf";
using (Watermarker watermarker = new Watermarker(File.OpenRead(path)))
{
var pdfContent = watermarker.GetContent<PdfContent>();
var searchCriteria = new VectorSearchCriteria();
var watermarkColor = ColorTranslator.FromHtml("#a9aaae");
var fromSystemColor = GroupDocs.Watermark.Watermarks.Color.FromArgb(watermarkColor.A, watermarkColor.R,
watermarkColor.G, watermarkColor.B);
var criteriaVectorColorRange = new ColorRange(fromSystemColor)
{
MinBrightness = 0.1f,
MaxBrightness = 0.7f
};
searchCriteria.VectorColorRange = criteriaVectorColorRange;
var possibleWatermarkCollection = pdfContent.Search(searchCriteria);
possibleWatermarkCollection.Clear();
watermarker.Save(outputFilePath);
