💖 g.cairocomp — GRASS GIS User's Manual 💖

okay bestie, welcome to the g.cairocomp(1) page, straight out of the GRASS GIS User's Manual ✨ she's a little niche, she's a little mysterious, and she is not for the faint of heart. let's get into it 🫶

🌈 DESCRIPTION 🌈

g.cairocomp isn't meant for end users. like, genuinely, she said "not for you bestie" and she meant it 💀 this is an internal-use situation, iykyk.

g.cairocomp is similar to g.pnmcomp, except that it works with X Pixmaps instead of PNM files. that's the whole plot twist, that's the lore 🎀
