I've repeated one of the earlier tests with the axes color set to "none"
close all
graphics_toolkit fltk
h = plot ([0, 0.5, 1], [0, 0.5, 1], '-sb');
set (h, 'markerfacecolor', 'b', 'markersize', 20, 'linewidth', 4)
hold all
h = plot ([1, 0.5, 0], [0, 0.5, 1], '-or');
set (h, 'markerfacecolor', 'r', 'markersize', 20, 'linewidth', 4)
set (gcf (), 'color', 'none')
print -depsc junk1.eps
I thought that the objects might just be rendered in the wrong order ... the
two lines were draw in the proper order, so that wasn't it.
Next, I looked over your patch and noticed you had removed the duplicate
"Fl:check ();". I don't recall why that was duplicated, but when I reinstated
the both "Fl:check ();", then the output looks as expected.
// it seems that we have to call Fl::check twice to get everything drawn
Fl::check ();
// Andy: Do we really have to? I can't see a problem with a single call
Fl::check ();
}
My test script is ...
close all
graphics_toolkit fltk
h = plot ([0, 0.5, 1], [0, 0.5, 1], '-sb');
set (h, 'markerfacecolor', 'b', 'markersize', 20, 'linewidth', 4)
hold all
h = plot ([1, 0.5, 0], [0, 0.5, 1], '-or');
set (h, 'markerfacecolor', 'r', 'markersize', 20, 'linewidth', 4)
set (gca (), 'color', 'c')
print -depsc junk1.eps
drawnow("eps", "dummy", false, "junk2.eps")
And the eps-files are attached.
