Hi,
This patch converts existing font to pf2. It uses the freetype2
library, so it can support most common file format, like bdf, pcf.gz,
ttf, etc.
Usage: grub-mkfont [OPTIONS] FONT_FILES
Options:
-o, --output=FILE_NAME set output file name
-i, --index=N set font index
-n, --name=S set font name
-s, --size=N set font size
-d, --desc=N set font descent
-b, --bold convert to bold font
-a, --auto-hint enable autohint
--no-bitmap don't use bitmap glyth
-h, --help display this message and exit
-V, --version print version information and exit
-v, --verbose print verbose message
