✨ GIF2RGB(1) ✨

okay bestie, sit down, we're learning gif2rgb from the giflib docs today 💖 this one's a little conversion goblin that flips images between GIF and raw RGB triplets, and honestly? it's giving "small tool, big opinions" 🎀

🌸 NAME 🌸

gif2rgb — convert images saved as GIF to 24-bit RGB triplets 💅

🦋 SYNOPSIS 🦋

gif2rgb [-v] [-1] [-c colors] [-s width height] [-o outfile] [-h]
        [gif-file]

👑 OPTIONS 👑

  • -v — verbose mode, aka show me the progress bestie. It turns on printout of the running scan lines. 🔥
  • -1 — only one file is read or written, in the format of RGBRGB... triplets (each of R, G, B is a byte). That file's size is 3 * Width * Height. If stdin is used for input, or stdout for output, this option gets applied implicitly — no cap. The default (when you don't pass -1) is 3 files named OutFileName.R, OutFileName.G, OutFileName.B, and each of those is Width * Height bytes.
  • -c colors — sets how many colors to use in RGB-to-GIF conversions, measured in bits per pixel. so -c 8 actually means 256 colors, which is the maximum and also the default. 💜
  • -s width height — puts you in RGB-to-GIF conversion mode and sets the size of the image to read. 🌈
  • -o — specifies the name of the out file (peep -1 above for the whole one-file-or-three-files situation 👀).
  • -h — prints one line of command line help, kinda like the Usage line above. tiny but iconic.

🧚 THE VIBES (aka how it actually behaves) 🧚

By default, it converts a GIF input file into RGB triplets. But the second you throw -s in there, the whole energy flips and it converts RGB input into a GIF instead. ✨

And if you hand it no input file at all? gif2rgb will just try to read data from stdin. main character behavior honestly 🫶

💀 BUGS 💀

Feeding this utility a GIF with an invalid colormap, or other kinds of malformations, will produce invalid output and may core-dump the tool. Don't do that. fr fr. 😭
