These are various scripts for generating .pcf fonts from .bmp images.
The original goal was to turn the ComputerCraft term_font.png file into a valid X11 font, although it can now be used to read and generate many fonts.
The scripts are written in Lua 5.3.
As of right now these scripts map the glyphs to Latin1 (ISO 8859-1),
I might at some point look at mapping them to
Unicode, so all characters are
printable, e.g. mapping glyph 127 onto U+2592 instead of U+007F
(the DELETE character, which is of course not printable).
# Remaking the `.pcf` files
lua ./bmp2pcf.lua term_font.bmp ccmono6x9r.pcf --family CCMono --width 16 --padright 1 --padbottom 1
lua ./bmp2pcf.lua term_font.bmp ccmono12x18r.pcf --family CCMono --width 16 --padright 1 --padbottom 1 --scale 2 # Scale font to prevent anti-aliasing
# Installing the fonts (Ubuntu)
sh ./install.sh ccmono*.pcf
# Testing the font once installed (You might have to restart your application
# and switch to the ccmono font first)
lua ./testfont.lua
# Uninstalling the fonts
sh ./uninstall.sh ccmono
Binary file format used by Linux to efficiently load font ROMs into video memory (fixed width only)
Binary file format used by X11 to efficiently store bitmap fonts (fixed and variable width)
Text file format originally used by Adobe to define bitmap fonts (fully compatible with PCF)
