# This small script is designed to mostly take a BDF file and convert it to a |
|
# format that can largely be cut/pasted as an Adafruit-format font. |
|
# It was written in an hour or so and did what I needed it to do. |
|
# I used it for one file. Maybe it bombs on other files. |

|
# Usage: bdf2adafruit.py <somefont.bdf> > out.txt |
|
# |
|
# Once you have out.txt you can cut/paste the contents into a new font |
|
# header file as part of the Adafruit GFX library. |
