This is indeed the easiest way to do it.

Now, if you really need "fully batch" operation (with no window 
opening), then you'll need to recompile Gmsh from the source code with 
the "--enable-osmesa" configure option. When the above script is run in 
batch mode (say, using "gmsh view.geo -"), the bitmap image will be 
generated off-screen. Note that this has only been tested on Linux.
