TTF to BDF conversion
The tool otf2bdf can convert the truetype font into bitmap format (bdf). For a linux environment, otf2bdf should be available as software package.
This conversion is done for a specific point size:
otf2bdf -p <pointsize> -r 75 -o <fontname>.bdf <fontname>.ttf
The result can be checked with `fontforge'.
Introduction
bdf2u8g converts a bdf font (glyph bitmap distribution format) to the internal u8glib font format
Update v1.13
The section specifier for the font array will change for U8lib v1.13. For any custom fonts the old section specifier
U8G_SECTION(".progmem.fontname")
should be replaced by
U8G_FONT_SECTION("fontname")
U8glib v1.13 already contains the correct section specifier. The new version of bdf2u8g will also generate the new section specifier.
