Command Line for DXF to PNG

I know the professional version provides the dwg2bmp command line tool, which allows DWG/DXF to bitmap conversion. However I only need to convert DXF to PNG in command line, is this achievable in the community edition or do I have to purchase the pro version? I see the BitmapExport.js under scripts\File\BitmapExport, is there any way to call this script directly to convert DXF to DWG?

Thanks.

Not out of the box. It would indeed be the idea that you would purchase a pro license for that kind of advanced functionality.
