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"
using (Watermarker watermarker = new Watermarker(Constants.InDocumentPdf))
{
Regex regex = new Regex(@"^© \d{4}$");
// search by regular expression
TextSearchCriteria textSearchCriteria = new TextSearchCriteria(regex);
// find possible watermarks using regular expression
PossibleWatermarkCollection possibleWatermarks = watermarker.Search(textSearchCriteria);
Console.WriteLine("Found {0} possible watermark(s).", possibleWatermarks.Count);
}
