Latex math text in PIL ImageDraw text()

I'm trying to annotate a few figures I created in python. So, I'm generating an image containing the specified text (using PIL ImageDraw) and concatenating it with the image. Now, I want to include a math notation into the text. Is there a way to write text in latex math when creating the image of text? This answer suggests a work-around by using unicode text, but I would prefer writing the text in latex directly.

MWE:

from PIL import ImageFont, Image, ImageDraw

from matplotlib import pyplot

def get_annotation(image_shape: tuple, title: str, font_size: int = 50):

frame_height, frame_width = image_shape[:2]

times_font = ImageFont.truetype('times-new-roman.ttf', font_size)

text_image = Image.new('RGB', (frame_width, frame_height), (255, 255, 255))

drawer = ImageDraw.Draw(text_image)

w, h = drawer.textsize(title, font=times_font)

drawer.text(((frame_width - w) / 2, (frame_height - h) / 2), text=title, fill=(0, 0, 0), font=times_font,

align='center')

annotation = numpy.array(text_image)

return annotation

if __name__ == '__main__':

anno = get_annotation((100, 300), 'frame $f_n$')

pyplot.imshow(anno)

pyplot.show()

I tried passing frame $f_n$ to title parameter, but dollars got printed in the text image.
