otf2bdf and bdf2psf could be used for that, for instance if the user
specifies the width (which will be the most probable use, people usually
don't care how many lines there are, but do care how many characters per
line there are; it's also the most difficult since fonts size is
configured through height, not width):
WIDTH=1024
HEIGHT=768
SCREEN_WIDTH=80
GLYPH_WIDTH=$(($WIDTH / $SCREEN_WIDTH))
GLYPH_HEIGHT=$(($GLYPH_WIDTH * 18 / 10))
otf2bdf -r 72 -p $GLYPH_HEIGHT /usr/share/fonts/truetype/ttf-dejavu/DejaVuSansMono.ttf | sed -e "s/AVERAGE_WIDTH.*/AVERAGE_WIDTH ${GLYPH_WIDTH}0/" > /tmp/font.bdf
bdf2psf --fb /tmp/font.bdf /usr/share/bdf2psf/standard.equivalents /usr/share/bdf2psf/ascii.set 256 /tmp/font.psf
There are just a few issues: bdf2psf wants an average width dividible by
10 and uses it as maximum width. This doesn't really make sense, letter
'i' for instance makes the average way smaller than what is needed for @
or W :) Perhaps bdf2psf could be made to have an option to specify the
width instead. Also, I've here cheated by hardcoding a 18/10 ratio. I
don't know how we could get this from the font file.
