[Octave-bug-tracker] [bug #33765] (FLTK) linestyles not respected for print

[Rik]

Follow-up Comment #5, bug #33765 (project octave):

The problem seems to be that the variable use_stipple is not being passed in
correctly.  I hardwired use_stipple in gl2ps-render.h like so


  void set_linestyle (const std::string& s, bool use_stipple)
  {
    //opengl_renderer::set_linestyle (s, use_stipple);
    opengl_renderer::set_linestyle (s, true);
    //if (use_stipple)
    if (true)
      gl2psEnable (GL2PS_LINE_STIPPLE);
    else
      gl2psDisable (GL2PS_LINE_STIPPLE);
  }



and then used the reporter's example


X = linspace(0,2*pi,1000);
Y1 = sin(X);
Y2 = cos(X);
plot(X,[Y1;Y2],'LineStyle','--')

print -dpng test.png


The output shows the correct dashed line.

Now we just need to trace back and figure out who is calling set_linestyle
with the wrong value of use_stipple.
