Hi Raj,


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

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 watermark with Aspose.Pdf using deleteStampById() method but in this case watermark should be added using Aspose.Pdf API. Please check following sample code for the 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()); }

}

contentEditor.save(myDir+"Hellowrold_deletestamp.pdf");
