How to identify headings in pdf document

i want to identify headings/different titles in pdf document.plz guide me in right direction so i can solve my problem.thank you

Dear customer,

Thanks for considering Aspose.

Your requirement is not supported in current version. And it seems not easy to support because there is no enough infomation to specify which part text is a title or heading. After written into the pdf, all the text has been just a text object with some format information which can't declare it is a heading or not.

Best regards.
