Generate Previews from external Script

Hi Community,

we re trying to extract information from CDR, etc documents from an external script like command line, etc..

The main information we need is 

. preview in jpeg or png quality

. number of pages

. full text

I'm totally new to this community and the automation of CorelDraw itself - so I hope someone could give me a hand on this...

Is there an option / what is the best option for externally generating / extracting those information? Is this also available on a faceless Linux installation like RHEL / CentOS?
