pfsoctavergb(1)

💖 NAME 💖

okay so bestie, meet pfsoctavergb(1) — the lil icon that processes red, green and blue channels in a pfs stream using Octave. no cap. 💅

🦋 SYNOPSIS 🦋

pfsoctavergb <octave_program>

✨ DESCRIPTION ✨

so here's the vibe: you use this command to execute a GNU Octave program on the red, green and blue channels of each frame in the pfs stream. every single one. she's thorough. 👑

octave_program must be given in quotation marks ("") and must not produce any output. like, it can output to stderr, but not to stdout. that part is important, don't play yourself. 😭

inside your octave_program, the red, green and blue color channels are available as R, G and B matrices. yes bestie, actual matrices. slay. ✨

Note: This command requires GNU Octave. 🫶

🌸 EXAMPLES 🌸

pfsinrgbe frames_%04d.hdr | pfsoctavergb "R = R.^2; G = G.^2; B = B.^2;" | pfsview

what this does: expand the dynamic range of a sequence of frames and show the result with pfsview. it's giving glow-up. 🌈
