✨ if2(1) — the manual, but make it cute ✨

okay so bestie, welcome to if2, living in the Engineering section of the manual, and it's literally the math girlie of the CTSim fam 💖

🎀 NAME 🎀

if2 — binary operations between two image (IF) files. yeah. two files. one output. math. slay.

🦋 SYNOPSIS 🦋

if2 infile1 infile2 outfile [OPTIONS]

🌸 DESCRIPTION 🌸

if2 performs binary functions on two input IF image files. that's it, that's the whole vibe — you give it two images, you tell it what to do with them, it gives you an output file. iconic behavior honestly 🫶

✨ OPTIONS ✨

if2 accepts the following options:

• --add — Add infile1 and infile2. 💅
• --sub — Subtract infile2 from infile1. (order matters, bestie, don't come for me)
• --mul — Multiply images.
• --comp — Compare images.
• --column-plot n — Plot column n.
• --row-plot n — Plot row n.
• --verbose — Verbose mode. it talks more. we love a chatty queen 👑
• --version — Print version.
• --help — Print terse help summary.

🌈 HISTORY 🌈

ngl this is a whole saga. CTSim was begun in 1983 using MS-DOS and an EGA display adapter. (yes. EGA. ancient. but highkey iconic for its time 💀✨) In 1999 it was ported to GNU/Linux and later ported to Microsoft Windows. the glow-up is real.

ok that's the whole page, no cap. go forth and do binary math on ur images bestie 💖

and one lil sign-off: this whole thing was written by Kevin Rosenberg for the if2(1) page in the Engineering manual, and the footer is just his name sitting pretty next to if2(1) at the bottom. that's the whole footer energy. periodt. 🎀🦋✨
