[Gmsh] How to generate .png files for all .geo files in a directory.

[Mark Starnes]

That's great James.  Searching for `Draw' in the manual pointed me to example t8.geo, including rotations too!

Thanks for helping.

Best regards,

Mark.

Yes, once you have the mesh created, you can used the Draw and Print command, e.g.

// Generate mesh, set transformation, etc.
Draw;
Print "thumbnail.png";

Hi everyone,

I have hundreds (well, more) of .geo files and I was wondering if there was a way to
call, from the command line, gmsh such that a two dimensional mesh is created and
the output saved as a .png, for viewing with a thumbnail viewer.  I can create the mesh
from the command line ok, but when I specify an output filename, a mesh is being saved
when I specify .png as the extension.  I think this is the expected behaviour (from reading
the manual).

Is it possible to generate images in this way?

Best regards,

Mark.
