tgx-font

A collection of plain and anti-aliased fonts to use with the tgx 2D/3D graphic library

The plain fonts are encoded in ILI9341_t3_font_t v1 format compatible with the ILI9341_t3 library.

The antialiased fonts are in ILI9341_t3_font_t v2.3 format whose description can be found here and supported also by the Teensy specific ILI9341_t3n library.

A preview of all the fonts is available here.

Notes

1. All fonts were downloaded from Google Font

2. The repo is organized as follow

   • /ttf contains the original font in ttf format.
   • /bdf contains the font converted to BDF (version 2.3 with AA).
   • /src contains the .cpp/.h files with the font in the final ILI9341_t3_font_t format.
   • /tools contains a Python3 script to convert from bdf fonts to source .cpp/.h files.
   • /examples contains examples on how to use the fonts (for Teensy, with tgx and my ILI9341_T4 driver).

3. The naming of the fonts follows the convention: font_[FONTNAME]_[AAx]_[lite]_[SIZE] where

• FONTNAME is the name of the font (possible including the 'italic' or 'bold' qualiier)
• AAx is the antialiasing strategy:
  • AA2 for 2 bit (4 levels of gray).
  • AA4 for 4 bit (16 levels of gray).
  • Nothing for plain font (no anti-aliasing).
• lite means that only the characters 32-126 are available in the font (in order to make the font smaller). If this qualifier is omitted, all available characters in the range 32-255 are included in the font.
• SIZE if the ref. height of the font in pixels.

4. Each font is available in size 8,9,10,14,16,18,20,24,28,3,36 and in plain/AA2/AA4 format. Each font is also generated in normal and lite version.
