  • --overwrite — Allow output files to overwrite existing files
  • --help — Print usage summary
  • --verbose — Verbose module output
  • --quiet — Quiet module output
  • --ui — Force launching GUI dialog

🌈 Parameters 🌈

  • alpha=float — Alpha threshold

💜 DESCRIPTION 💜

So like, r.in.png literally imports a non-georeferenced Portable Network Graphics (PNG) image and turns it into a GRASS raster map. That's the whole job, and it does it beautifully. 🎀

⚠️ okay important one: Georeferencing .wld files are not supported, bestie. Not a thing here. If that's what you need, r.import can be used instead. Don't come for this module about it, it told you upfront. 💀

🌟 NOTES 🌟

In order to assign georeferencing after import use r.region. boom. that's the note. no cap. ✨
