NB Code Formatting as a Library??

Hi, Mark.   
As for me, I have seldom tried toconvert Stack Overflow posts to PDF. I wonder have you ever worked it out? Do I need another 3rd party manual toolkit? When it comes to PDF converting (http://www.pqscan.com/convert-pdf/) process, I have another question, I wonder have you ever tried to convert pdf to other image files (http://www.pqscan.com/pdf-to-image/) before? As for myself, I am testing the related PDF to PNG converting, PDF to BMP converting , and PDF to JPG converting programs these days.  Do you have experience about it? Any suggestion will be appreciated. Thanks in advance.                            




Best regards,
