How to add custom font in SchemDraw?

Question

SchemeDraw, python's library to draw many things, provides an option to configure global style using schemdraw.config(font="serif"). However, there is no mention of all the fonts supported nor how to add a custom font.

Is there a way to add a font using .ttf file in schemdraw?

Thank you !

Answer 1

SchemDraw uses matplotlib's fontfamily and the fonts installed in the system. In order to add a custom font using .ttf file, we have to add the font to matplotlib using its font_manager as shown below.

from matplotlib import font_manager

fpath = '/path/to/custom_font.ttf'
font_manager.fontManager.addfont(fpath)

The above snippet caches the font and then the name of the font can be used in SchemDraw directly. For example, schemdraw.config(font='custom') to config the font globally for the whole drawing.
