mia-multihist(1)

💖 mia-multihist(1) — the glow-up edition 💖

okay bestie, pull up a chair because this one's a whole vibe. we're talking about mia-multihist(1), straight out of the General Commands Manual, and it's lowkey one of the most useful little tools in the whole fam. 🦋

---

✨ NAME ✨

mia-multihist — it makes a histogram of a whole series of 2D images. like, all of them. every single one. no cap. 👑

---

🌸 SYNOPSIS 🌸

mia-multihist -i <in-file> -o <out-histogram> [options]

---

💅 DESCRIPTION 💅

mia-multihist is that girl. 💖 This program evaluates the histogram over a series of 2D images. that's it, that's the job, and it does it flawlessly fr fr.

---

🎀 OPTIONS 🎀

• -i, --in-file=(input, required) — the input image(s) to be filtered. it's io type, it's required, so don't ghost it. 🙈
  • For supported file types see PLUGINS:2dimage/io (yes, that section is down below, keep scrolling bestie ⬇️)
• -o, --out-histogram=(output, required) — output file name. it's a string. required. periodt. 💅
• --min=0 — minimum of histogram range. defaults to 0.
• --max=65535 — maximum of histogram range. defaults to 65535.
• --bins=65536 — number of histogram bins. defaults to 65536. set it to zero to create a bin for each intensity value available in the input data — and in that case the histogram range is also evaluated automatically. iconic behaviour honestly. ✨

🌈 Help & Info 🌈

• -V, --verbose=warning — verbosity of output; prints messages of the given level and higher priorities. defaults to warning. the 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. give the lawyers their moment 🫶
• -h, --help — print this help. the classic.
• -?, --usage — print a short help. the lite version, for when you're in a rush.
• --version — print the version number and exit. bye bestie 👋

🧚 Processing 🧚

• --threads=-1 — Maxiumum number of threads to use for processing. (yes that typo is in the original, we do not fix, we preserve 🫡) This number should be lower or equal to the number of logical processor cores in the machine. -1 means automatic estimation. let the machine cook. 🔥

🔥 PLUGINS: 2dimage/io 🔥

here's the roster of file formats that can pull up to the party:

• bmp — BMP 2D-image input/output support. The plug-in supports reading and writing of binary images and 8-bit gray scale images. read-only support is provided for 4-bit gray scale images. The color table is ignored and the pixel values are taken as literal gray scale values.
  • Recognized file extensions: .BMP, .bmp
  • Supported element types:
    • binary data, unsigned 8 bit
• datapool — Virtual IO to and from the internal data pool.
  • Recognized file extensions: .@

• tif — TIFF 2D-image input/output support.
  • Recognized file extensions: .TIF, .TIFF, .tif, .tiff
  • Supported element types:
    • binary data, unsigned 8 bit, unsigned 16 bit, unsigned 32 bit
• vista — a 2dimage io plugin for vista images.
  • Recognized file extensions: .-, .V, .VISTA, .v, .vista
  • Supported element types:
    • binary data, signed 8 bit, unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit, floating point 32 bit, floating point 64 bit

⭐ EXAMPLE ⭐

okay so imagine this: you wanna evaluate the histogram over all consecutively numbered images that follow the numbering pattern inputXXXX.exr and store the output histogram in histo.txt. and you want the range [0,256] with 64 bins. here's the moment:

mia-multihist -i input0000.exr -o histo.txt --min 0 --max 256 --bins 64

ate. no crumbs. 💅✨
