# Program to generate a PNG file suitable for use as a rEFInd font
|
|
# To obtain a list of available font names, type:
|
|
#
|
|
# convert -list font | less
|
|
#
|
|
# The font used MUST be a monospaced font; searching for the string
|
|
# "Mono" will turn up most suitable candidates.
|
|
#
|
|
# Usage:
|
|
# ./mkfont.sh font-name font-size font-Y-offset bitmap-filename.png
|
|
#
|
|
# This script is part of the rEFInd package. Version numbers refer to
|
|
# the rEFInd version with which the script was released.
|
|
#
|
|
# Version history:
|
|
#
|
|
# 0.6.6 - Initial release
