Hi Laxman,


Thanks for contacting support.

In order to accomplish your requirement, please try using CreateMarkup(…) method of PdfContentEditor class. Please take a look over the following code snippet.

For your reference, I have also attached the sample PDF file generated with this code.

[C#]

PdfContentEditor editor = new
PdfContentEditor();<o:p></o:p>

editor.BindPdf("c:/pdftest/A5SizePDF2.pdf");

editor.CreateMarkup(new System.Drawing.Rectangle(87,513, 90,10),"", 0, 1, System.Drawing.Color.Yellow);

editor.Save("c:/pdftest/HighLighted_Text_example_out.pdf");

Hi Laxman,


In case you need to search particular string and need to get its coordinates/position information, then I would suggest you to please try using the code snippet shared over Replace Text in All Pages of a PDF Document (instead of replacing the whole string, you can only specify/set the ForgroundColor of TextFragment.

In the event of any further query, please feel free to contact.
