🎀 KEYWORDS 🎀

🦋 SYNOPSIS 🦋

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

🫶 Flags

• -p — output the values as percentages instead of... not percentages. simple as that.
• --overwrite — lets output files just bulldoze right over existing files like it's nothing 😭
• --help — prints the usage summary, aka the "what do i even type" lifeline
• --verbose — verbose module output, so she tells you everything she's doing
• --quiet — quiet module output, shhh 🤫
• --ui — forces the GUI dialog to launch, for when you want the clicky version

🍓 Parameters

• map=name [required] — name of the 3D raster map. yes you have to give her one.
• rules=name — path to the output rules file. if you don't give her one, she writes to standard output instead 🫶
• format=name [required] — the output format. options: plain, json. default: plain.
  • plain: plain text output
  • json: JSON (JavaScript Object Notation)
• color_format=name [required] — the color format, aka the color format for output values. options: rgb, hex, hsv, triplet. default: hex.
  • rgb: output color in RGB format
  • hex: output color in HEX format
  • hsv: output color in HSV format (experimental — she's still testing that one, be gentle 🧚)
  • triplet: output color in colon-separated RGB format

🌈 DESCRIPTION 🌈
