✨ MRCAL(1) ✨

okay so bestie, you've stumbled into the mrcal man page zone — camera projection, calibration toolkit energy, and honestly? iconic. this one's about mrcal-to-cahvor, and yes it does exactly what it says on the tin 💅

💖 NAME 💖

mrcal-to-cahvor — converts a cameramodel to the cahvor file format

no cap, that's the whole job. she's a format converter and she's thriving.

🎀 SYNOPSIS 🎀

  $ mrcal-to-cahvor model1.cameramodel model2.cameramodel
  Wrote model1.cahvor
  Wrote model2.cahvor

see how chill that is? you hand her some models, she hands you back .cahvor files and a lil receipt. main character behavior fr fr 🦋

🌸 DESCRIPTION 🌸

File formats supported by mrcal are described at <https://mrcal.secretsauce.net/cameramodels.html#cameramodel-file-formats>

This tool converts the given model(s) to the cahvor file format. No changes to the content are made; this is purely a format converter (the mrcal-convert-lensmodel tool fits different lens models instead). Model filenames are given on the commandline. Output is written to the same directory, with the same filename, but with a .cahvor extension.

so like. no glow-up, no edits, no notes — she is not changing your content, she's just putting it in a different outfit. if you actually wanted a different lens model, that's mrcal-convert-lensmodel's whole thing, not hers. don't come for her about it 😭

you pass the model filenames on the commandline, and the output lands in the same directory with the same filename, except the extension is now .cahvor. periodt.

🫶 and if the model is omitted, or given as -, the input is read from standard input, and the output is written to standard output. pipes? she loves pipes.

🌈 OPTIONS 🌈

🌟 POSITIONAL ARGUMENTS 🌟

  • model — Input camera model. the whole point. the moment. the vibe check. give her one (or more) and she'll convert them 💖

⭐ OPTIONAL ARGUMENTS ⭐

  • -h, --help — show this help message and exit. tiny, helpful, beloved.
  • --force, -f — By default existing files are not overwritten. Pass --force to overwrite them without complaint. so like, by default she's polite and won't clobber your stuff. --force is her "say less" mode — she overwrites and does not complain about it at all 💀
  • --outdir OUTDIR — Directory to write the output models into. If omitted, we write the output models to the same directory as the input models. basically: tell her where to drop the files, or she'll just leave them right next to their siblings 🎀
