I came across this site, which uses machine learning to generate a typeface.

In the method, they mention that

A styleGAN model was trained in RunwayML on a dataset of 2674 Google fonts organised as individual image-per-glyph in Drawbot.

I was able to find a script that generates images from a single font file, but I need it to be able to handle several thousand. The code is here:

# use absolute or relative path. This can be OTF or TTF.
font_path = 'my_font.otf'
# set the current font to be the one specified above, so we can list its glyph names:
font(font_path)
# loop through the list of glyph names:
for gid, g_name in enumerate(listFontGlyphNames()):
    # the new page is 1000 by 1000 points by default
    newPage()
    fs = FormattedString(
        font=font_path,
        fontSize=500,
        align='center',
        )
    # writing the glyph name into the formatted string
    fs.appendGlyph(g_name)
    # a text box in which the string is used
    textBox(fs, (0, 0, 1000, 800))
    # using the GID for the file name, because macOS is not case sensitive:
    saveImage(f'~/Desktop/{gid}_{g_name}.png')

Could someone please advise me on how I could achieve this? I already have a large folder of ttf files ready to be converted.

Thanks in advance!!
