[Octave-bug-tracker] [bug #31468] multi-line text objects

[Vanya Sergeev]

Follow-up Comment #28, bug #31468 (project octave):

It turns out gl2psTextOpt() (used for opengl plot printing) does not account
for newline characters "n", "r", or "rn".


octave:1> graphics_toolkit("fltk")
octave:2> plot([1,2,3,4,5])
octave:3> set(get(gca(), "title"), "string", "abcndef")
octave:4> print("test1.png", "-dpng")
octave:5> set(get(gca(), "title"), "string", "abcrdef")
octave:6> print("test2.png", "-dpng")
octave:7> set(get(gca(), "title"), "string", "abcrndef")
octave:8> print("test3.png", "-dpng")


All plots come out with "abc def" on one line...

Perhaps gl2psDrawPixels() ( http://geuz.org/gl2ps/#tth_sEc2.3 ) should be used
instead of gl2psTextOpt() with the pixel array generated by the ft_render
class, to support multi-lines in the gl2ps prints?

Thanks,
