[Octave-bug-tracker] [bug #52975] regression: print to svg contains two backplanes, one black and one white

[Rik]

Follow-up Comment #3, bug #52975 (project octave):

This might be caused by the way we handle GL2PS_DRAW_BACKGROUND.  We
specifically enable this option for the first viewport, and then disable it
for other axes objects like legends.  This is in gl2ps-print.cc:draw_axes.


      // Don't draw background for subsequent viewports (legends, subplots,
      // etc.)
      gl2psGetOptions (&opts);
      opts &= ~GL2PS_DRAW_BACKGROUND;
      gl2psSetOptions (opts);
