[Octave-bug-tracker] [bug #53186] Without osmesa it is not possible to print/getframe invisible figures

[Dmitri A. Sergatskov]

Follow-up Comment #12, bug #53186 (project octave):

I am still not sure what is happening:


octave:1> fh = figure("visible", "off")
fh =  2
octave:2> plot(randn(10))
octave:3> print("t1.png")
error: __osmesa_print__: support for offscreen rendering with OSMesa was
unavailable or disabled when Octave was built
error: called from
    __opengl_print__ at line 172 column 7
    print at line 520 column 14


__octave_config_info__ ("hg_id")
ans = d3a79cb734d2

This all seems in accord with 
scripts/plot/util/private/__opengl_print__.m



    if (strcmp (get (opts.figure, "visible"), "on"))
      ## Use toolkits "print_figure" method
      drawnow (gl2ps_device{n}, ['|' pipeline{n}]);
    else
      ## Use OpenGL offscreen rendering with OSMesa
      __osmesa_print__ (opts.figure, ['|' pipeline{n}], gl2ps_device{n});
    endif
  endfor



Dmitri.
