[Octave-bug-tracker] [bug #31305] slow contour plot

[John W. Eaton]

Follow-up Comment #43, bug #31305 (project octave):

Almost all of the time seems to be spent here:


  //FIXME: text_renderer could be cached
  ft_render text_renderer;
  text_renderer.set_font (get ("fontname").string_value (),
                          get ("fontweight").string_value (),
                          get ("fontangle").string_value (),
                          get ("fontsize").double_value ());


in the function axes::properties::get_ticklabel_extents in the file
graphics.cc.  So yes, I'd say that caching text_renderer is the right thing to
do!
