uGUI is a free open source graphics library for embedded systems. To display text, it uses bitmap/raster fonts, that are included in application as C-language structs & arrays. uGUI includes some fonts in itself, but I wanted to use some TrueType fonts.
I didn't find a tool that would convert a .ttf file into C structures used by uGUI easily, so I wrote one using Freetype library.
This is a simple utility to convert TrueType fonts into uGUI compatible structures. It reads font file, renders each character into bitmap and outputs it as uGUI compatible C structure.
Optionally it can display ascii art sample of font by using UGUI to render pixels as '*' with ansi escape sequences.
Please remember to respect font copyrights when converting.
Examples:
Convert font in Luna.ttf to 14 point size bitmap font for 140 DPI display:
ttf2ugui --font Luna.ttf --dpi 140 --size 14 --dump > luna.c
Show ascii art of same font:
ttf2ugui --font Luna.ttf --dpi 140 --size 14 --show
