how to use bold variant of a font

[aslamhadi]

Hi, thanks for creating this amazing library.

So I installed Heebo font and I confirmed that it's installed in /usr/share/fonts/googlefonts. I also have run RUN fc-cache -f -v to refresh the font list.

How do I use the bold variant? I tried label(test_label,200,250,15,ffffff,0,Heebo:style=Bold) but it doesn't change to the bold one. Thanks before
