Hi Rashid,
I was also looking for a similar solution.
I tried using this peiece of code .
//create a new PdfContentEditor object
PdfContentEditor contentEditor = new PdfContentEditor();
//bind input PDF file
contentEditor.BindPdf("input.pdf");
//get information of all the stamps on a particular page
StampInfo[] stampInfos = contentEditor.GetStamps(1);
//show information of all the stamps
foreach (StampInfo stampInfo in stampInfos)
{
contentEditor.DeleteStamp(stampInfo.StampId);
}
//save output PDF file
contentEditor.Save("output.pdf");
It helped me remove the TextStamp successfully, but I was getting the an error "AN ERROR EXISTING ON THE PAGE. ACROBAT MAY BE DISPLAY THE PAGE PROPERLY"
Could you help on this, please.
