💅 blind-set-saturation(1) — General Commands Manual 💅

okay so bestie, this is the blind-set-saturation(1) page from the General Commands Manual, and the manual name is literally right there in the title: blind-set-saturation. it's giving “tiny utility, main character energy,” and we're gonna get into it. 🎀

✨ NAME ✨

blind-set-saturation — multiply the saturation of a video. that's the whole name, and honestly? it ate. 💅

🦋 SYNOPSIS 🦋

blind-set-saturation [-w] saturation-stream

🌸 DESCRIPTION 🌸

okay so here's the vibe: blind-set-saturation reads a video from stdin and a mask video from saturation-stream. the video is printed to stdout, with the saturation of each pixel multiplied by the product of the luminosity and the alpha value of the corresponding pixel and frame in the mask video. yes bestie, luminosity × alpha × saturation — that's the little math situation, and it's lowkey iconic. ✨

if stdin is longer than saturation-stream, the remainder of stdin is printed without any changes. no touchy, no saturation-ing, just vibes. 😌

if stdin is shorter than saturation-stream, the remainder of saturation-stream is ignored but may be partially read. so like, it might peek at the rest, but it does not finish it. 👀💀

🎀 OPTIONS 🎀

  • -w — instead of using CIE Standard Illuminant D65 as the whitepoint, use the X and Z from each pixel in saturation-stream for the whitepoint. that's the flag, that's the whole flag, and it's serving exactly what it needs to serve. 💖

mwah 💋 this page is blind 1.1 in the footer/source-version situation, and the header/footer are both repping BLIND-SET-SATURATION(1). there's no date printed in that footer, so I'm not inventing one — periodt. 🎀
