Hi RaviKant,

Thanks for your inquiry. You may remove image watermark using Aspose.Pdf, please try following the instructions specified over Delete Images from the PDF File.

Moreover, there is another convenient way to delete image/text watermark with Aspose.Pdf using DeleteStampById() method but in this case watermark must be added using Aspose.Pdf API with IDs.



//Open document

Document pdfDocument11 = new Document(myDir + "PageNumber.pdf");

//Create image stamp

ImageStamp imageStamp = new ImageStamp(myDir + "aspose_pdf.jpg");

imageStamp.Background = true;

imageStamp.XIndent = 100;

imageStamp.YIndent = 100;

imageStamp.Height = 300;

imageStamp.Width = 300;

imageStamp.Rotate = Rotation.on270;

imageStamp.Opacity = 0.5;

imageStamp.setStampId(111);

//Add stamp to particular page

pdfDocument11.Pages[1].AddStamp(imageStamp);

//Save output document

pdfDocument11.Save(myDir+"output_imageStamp.pdf");

//****Removing Stamp****//

PdfContentEditor contentEditor = new PdfContentEditor();

contentEditor.BindPdf(myDir + "output_imageStamp.pdf");

StampInfo[] stampInfo = contentEditor.GetStamps(1);

//contentEditor.DeleteStampById(111);

//Loop through each stamp

for (int i = 0; i < stampInfo.Length; i++)

{

//Check to see if the ID = 111, if so delete the stamp.

if (stampInfo[i].StampId == 111)

{ contentEditor.DeleteStampById(stampInfo[i].StampId); }

}

contentEditor.Save(myDir + "output_deletedstamp.pdf");
