Introduction

Loads bitmap fonts into CircuitPython's displayio. BDF and PCF files are well supported. TTF support is not yet complete.

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-bitmap_font

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-bitmap_font

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-bitmap_font

Usage Example

from adafruit_bitmap_font import bitmap_font
from displayio import Bitmap
font = bitmap_font.load_font("fonts/LeagueSpartan-Bold-16.bdf", Bitmap)
print(font.get_glyph(ord("A")))

Creating Fonts

See this learn guide for more information about building custom font files.
