uint32_t hsl_to_rgb(int hue, int sat, int lum);
hsl: add our own implementations of rgb-to-hsl and hsl-to-rgb * New function: rgb_to_hsl() * New function: hsl_to_rgb() * Replace XTerm’s hls_to_rgb() with our own, hsl_to_rgb(). * Ensure hue/lum/sat values are within range before calling hsl_to_rgb() Note that sixels’ use the following primary hues: * blue: 0° * red: 120 * green: 240° While “standard” HSL uses: * red: 0° * green: 120° * blue: 240° Thus, we need to adjust the sixel’s hue value before calling hsl_to_rgb(). 2020-11-15 19:45:33 +01:00			`#pragma once`
