Hi Raj,

Thanks for your inquiry. You can remove TextStamp/Watermark by replacing stamp contents with an empty text string as follows:

PdfContentEditor editor = new PdfContentEditor();
editor.bindPdf(myDir + "watermark.pdf");
editor.replaceText("Neevia Document Converter Pro v6.5",  " );
editor.save(myDir + "watermark_out.pdf");

Moreover, there is another convenient way to delete a watermark using Aspose.Pdf with the deleteStampById() method, but in this case, the watermark should be added using Aspose.Pdf API. Please check the following sample code for this purpose:

//****Adding Text Stamp****//
Document pdfDocument=new Document(myDir+"Helloworld.pdf");

Date dtest = new Date();

com.aspose.pdf.facades.FormattedText txtFormatted = new com.aspose.pdf.facades.FormattedText();

txtFormatted.addNewLineText("Processed/Reviewed By:");

txtFormatted.addNewLineText(dtest.toString());

TextStamp textStamp = new TextStamp(txtFormatted);

textStamp.setBackground(true);

textStamp.setBottomMargin(50);

textStamp.setHorizontalAlignment(HorizontalAlignment.Right);

textStamp.setVerticalAlignment(VerticalAlignment.Bottom);

textStamp.setYIndent(10);

textStamp.getTextState().setFontSize(10.0F);

textStamp.setOpacity(100);

//Set ID of stamp
textStamp.setStampId(999);

pdfDocument.getPages().get_Item(1).addStamp(textStamp);

//save output document
pdfDocument.save(myDir+"Helloworld_textstamp.pdf");

//Removing Text Stamp//

PdfContentEditor contentEditor = new PdfContentEditor();

contentEditor.bindPdf(myDir + “Helloworld_textstamp.pdf”);

com.aspose.pdf.facades.StampInfo[] stampInfo = contentEditor.getStamps(1);

//Loop through each stamp
for (int i = 0; i < stampInfo.length; i++){

//Check to see if the ID = 999, if so delete the stamp.
if (stampInfo[i].getStampId() == 999){
contentEditor.deleteStampById(stampInfo[i].getStampId());
}}

// save the updated document
contentEditor.save(myDir + “Hellowrold_deletestamp.pdf”);
