[Gmsh] Step model view export as png from command line/script

[Zuheyr Alsalihi]

Dear Gmsh creators,
 
Forever grateful for providing us with this fabulous tools and all your effort in support.

I am working with gmsh without user interface in an optimization process where everything is driven with command line gmsh options in shell scripts.

I just want to load the step files, export the resulting view, what I would have seen if I were working with gmsh with display, to png file, and that is it.

Can I do that? 
 
Thank you very much for reading.
Best regards.
