make_font

Convert a TrueType font into a bitmap font module for the board.

uv run tools/make_font.py DejaVuSans-Bold.ttf 40 src/font_large.py

The generated module holds 1-bit glyphs in MONO_HLSB order (rows of (width + 7) // 8 bytes, most significant bit left), as text expects. Pixels at least half covered by the anti-aliased rendering are set.

Attributes

FONT_DIR
CHARSET
FONT_LICENSE
