tfonts

Demonstrates large true type font rending in the terminal with multiple options (from truecolor to mono). tfonts will show a given text in all the fonts it finds in the system or indicated -fontdir. Or use a specific -font. Use the left arrow key or backspace to navigate back, q,Q or Ctrl-C to exit.

Heavy lifting is using ansipixels image to terminal rendering.

Ps: this was originally developed under my personal scratch repo github.com/ldemailly/go-scratch/tree/main/tfonts but got pretty good enough and clean enough to migrate here. Also thanks to the fine folks in Ghostty discord TUI channel for inspiration and ideas.
