Dear Albert, Thanks for your response. As discussed in the last mail, we have modified the patch so that: - There is no behavioural change in pdftohtml -c <filename> means it produces exactly the same output it did before. - Defined new option as pdftohtml -s <filename> to generate a single html file corresponding to a pdf file. Please check and give your feedback if any further change is required.
