💖 r3.colors.out — the GRASS GIS user's manual glow-up 💖

okay bestie, welcome to the manual for r3.colors.out, straight out of the GRASS GIS User's Manual. she's a lil one but she's so useful, no cap. ✨

KEYWORDS: raster3d, color table, export 🎀

🌈 NAME

r3.colors.out — she exports the color table that's attached to a 3D raster map. that's it. that's the whole job. and she ate. 💅

🦋 SYNOPSIS

r3.colors.out
r3.colors.out --help
r3.colors.out [-p] map=name  [rules=name]   [--overwrite]  [--help]
[--verbose]  [--quiet]  [--ui]

✨ FLAGS

  • -p — output the values as percentages, periodt. 🍓
  • --overwrite — lets output files overwrite files that already exist. she will simply replace them, bestie, so know that going in. 💀
  • --help — prints the usage summary, iykyk.
  • --verbose — verbose module output, she gets chatty. 🫶
  • --quiet — quiet module output, she shuts uppp. 🤫
  • --ui — forces the GUI dialog to launch. main character energy. 👑

🎀 PARAMETERS

  • map=name [required] — name of the 3D raster map. yes, required, you literally cannot skip her. 🙈
  • rules=name — path to the output rules file. if you don't give her one, she writes to standard output instead. easy. ✨

💜 DESCRIPTION

so r3.colors.out lets you export the color table of a 3D raster map out to a file, and that file is suitable as input to r3.colors. it's giving ✨ round trip ✨. lowkey iconic, honestly.

🌸 EXAMPLES

export it out:

r3.colors.out map=volume_1 rules=rules.txt

then feed it right back in:

look at her go. obsessed. 💖
