This is a helper library written in Python3 for replacing the default logo with a custom one in an OSD font.
from bflogoreplacer import replace_logo
with open("my-custom-font.mcm") as f:
f.write(replace_logo("digital.mcm", "my-logo.png"))See samples/ directory for example input/output.
- image has to be exactly 288px×72px
- background must be full green (#00ff00)
- must use white and black colors only
- it's better to use RGB mode than RGBA (alpha is ignored anyway)
- green areas will be transparent on the OSD
- default Betaflight fonts can be obtained from the configurator's repo:
