Chinese characters with Text2D

[ZiguoAtGitHub]

Hi, All
I copied the chinese font file into vedo font directory and coded the Text2D(...,font='font_file.ttf',...). But it didn't work.
Adding the path to the font_file as "c:\windows\font\font_file.ttf" did not work neither.

Call for help~
Thank you All!

Hi @ZiguoAtGitHub
that is strange - it works fine on my ubuntu system..
Have you tried examples/pyplot/caption.py, it supports Chinese chars:
font="LogoType"

Hi @marcomusy ,

First of all, Thanks for your reply.

Yes. it is very strange. I just download the caption.py that you refered and run as "python caption.py " in cmd(my pc env is win10, python 3.9.10), here is error.

The problem looks like caused by missing LogoType.ttf, doesn't it?

Then, I replace the font_file with STSONG.ttf which is found in system font directory and the error is:

And the vedo plot window is

Pls give me some help, Thank you!

BTW: Vedo is amazing to me, Great job!

Hi @marcomusy ,
As you mentioned well in the case of Text2D we take the shortcut and use the tff file directly.., , I took a try about plotting chinese chars by Text2D (the codes are kk=Text2D("This is a chinese words:简体中文(simplified chinese)", font='c:\\windows\\fonts\\STFANGSO.TTF', pos='top-left', c='red3'). Here is the result.

It looks like the parameter font='c:\windows\fonts\STFANGSO.TTF' only take effects on english characters and the chinese characters are skipped. Did I miss something?

Wating for your reply.
Thanks a lot!!

Hi @ZiguoAtGitHub I was hoping that was a problem with my version of STFANGSO but infact you got the same...
I think it must be a problem with the upstream VTK, I will try to send a request to the developers to see if they understand what happens with STFANGSO.ttf (it still works in 3D though in my local tests).
I'd love to see chinese chars in vedo!
Thanks for your patience

I am looking forward to that also. :)

Thank you again for your great job, it does give me more imaginary space for my job.

I've been playing around with online fonts (I love fonts) and this is what i've come up with:

pip install -U git+https://github.com/marcomusy/vedo.git

Then

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from vedo import Axes, Text2D, Text3D, show, settings

settings.default_font = "Housekeeper" # ~28MB
# settings.default_font = "Wananti"    # ~74MB

txt = ( "简体字是在中国大陆、"
        "马来西亚和新加坡使用的标准化汉字,\n"
        "由通用标准汉字表规定。\n"
        "与繁体字一起, \n"
        "它们是当代汉语书面语言的两个标准字符集之一。")


t2d = Text2D(txt, s=2)
t3d = Text3D(txt, c='blue2').bc("red5")

axes = Axes(
    t3d,
    xtitle='x 简体中文',
    ytitle='y 轴',
    text_scale=1.5,
)

show(t2d, t3d, axes, size=(1500,500)).close()
# for t in txt: print(t, '=', ord(t))

Wananti

they are pretty large files and the final result is not 100% perfect....
How does it look?
