mia-2dtransform(1)

💖 mia-2dtransform — ok bestie, we're warping images 💖

the manual name is mia-2dtransform, it lives in the General Commands Manual section, and it's about to become your whole personality 🦋

✨ NAME ✨

mia-2dtransform — Transform a 2D image. 💅

That's it, that's the job. You give it a picture, you give it a transformation, it hands you back a whole new picture. Iconic.

---

🌸 SYNOPSIS 🌸

mia-2dtransform -i <in-file> -o <out-file> -t <transformation> [options]

---

🎀 DESCRIPTION 🎀

So like, mia-2dtransform deforms a 2D image using a given transformation. You bring the image, you bring the transformation, it does the deformation thing. Lowkey the whole plot of the program. 🫶

---

💅 OPTIONS 💅

• -i, --in-file=(required, input); io — the input image. It's required, babes, no skipping. For supported file types see PLUGINS:2dimage/io (scroll down, it's all there 🌈)
• -o, --out-file=(output, required); io — the output image. Also required. You gotta know where the glow-up is going. For supported file types see PLUGINS:2dimage/io
• -t, --transformation=(required, input); io — the transformation file name. Required, obviously. For supported file types see PLUGINS:2dtransform/io
• -p, --interpolator= — override the interpolator provided by the transformation. Basically "no bestie, I'm picking the interpolator, not the transformation file." 💅
• -b, --boundary=mirror — override the boundary conditions provided by the transformation. Default is mirror, if you were wondering.

Heads up though: this is only used if the interpolator is overridden. So if you didn't touch -p, this one is just sitting there. Facts are facts. 😭

🆘 Help & Info 🆘

• -V, --verbose=warning — how chatty do you want it? It prints messages of the given level and higher priorities. Default vibe is warning. Supported priorities, starting at the lowest level, are:
  • trace — Function call trace
  • debug — Debug output
  • info — Low level messages
  • message — Normal messages
  • warning — Warnings
  • fail — Report test failures
  • error — Report errors
  • fatal — Report only fatal errors
• --copyright — print copyright information 📜
• -h, --help — print this help 🫶
• -?, --usage — print a short help
• --version — print the version number and exit ✨

---

🔥 Processing 🔥

• --threads=-1 — Maximum number of threads to use for processing. (yes the original says "Maxiumum", we love a typo moment, keeping it exactly as-is 💀) This number should be lower or equal to the number of logical processor cores in the machine. And -1 means automatic estimation. Let the machine cook. 👑

🦋 PLUGINS: 2dtransform/io 🦋

And these are the formats your -t transformation file can be. Yes, transformations have their own little format club.

• bbs — Binary (non-portable) serialized IO of 2D transformations
  • Recognized file extensions: .bbs
• datapool — Virtual IO to and from the internal data pool
  • Recognized file extensions: .@
• vista — Vista storage of 2D transformations
  • Recognized file extensions: .v2dt
• xml — XML serialized IO of 2D transformations
  • Recognized file extensions: .x2dt

⭐ EXAMPLE ⭐

Okay so the assignment: transform an image input.png by the transformation stored in trans.v, use linear interpolation and zero boundary conditions, and store the result in output.png. Slay.

mia-2dtransform -i input.png -t trans.v  -o output.png  -p bspline:d=1
       -b zero

fr fr, look at that double space after trans.v and before -o — we're keeping it exactly as the manpage wrote it. no edits, no cap. 💖

And that's the whole page, bestie — written for the USER COMMANDS section, version v2.4.7, and yeah it's giving very much mia-2dtransform(1) energy. Go warp something pretty. 🎀✨💖
