#!/bin/bash

printf "\n"
printf "    _   __                           __   \e[2m______      _       __ \e[0m\n"
printf "   / | / /___  _________ ___  ____ _/ /  \e[2m/ ____/___ _(_)___  / /_\e[0m\n"
printf "  /  |/ / __ \/ ___/ __ ´__ \/ __ ´/ /  \e[2m/ /_  / __ ´/ / __ \/ __/\e[0m\n"
printf " / /|  / /_/ / /  / / / / / / /_/ / /  \e[2m/ __/ / /_/ / / / / / /_  \e[0m\n"
printf "/_/ |_/\____/_/  /_/ /_/ /_/\__,_/_/  \e[2m/_/    \__,_/_/_/ /_/\__/  \e[0m\n"

Thanks. Faint attr support is missing indeed, but should be rather straightforward to add it.

[ku1ik]

Faint attr support is now available in the default (fontdue) renderer. This will be released with the next version, very soon.

We'll be able to also implement that in the alternative renderer (resvg) once opacity is supported on tspan elements in resvg (linebender/resvg#414).

[ku1ik]

So, I released 1.5.0 with this improvement (amongst many others). I made resvg renderer a default, as it gives overall better results (better font rendering, emoji, etc). Faint attr is not supported in it, but you can run agg --renderer fontdue ... to use fontdue renderer, which supports faint rendering.
