✨ NAME ✨

unu-unquantize — recover floating point values from quantized data 🦋

---

🌸 SYNOPSIS 🌸

unu unquantize -i,--input <nin> [-min,--minimum <value>] [-max,--maximum
<value>] [-double] [-o,--output <nout>]

---

💅 DESCRIPTION 💅

Recover floating point values from quantized data. Literally what it says. It peeks at the oldMin and oldMax fields chillin' inside the nrrd of quantized values, and uses those to regenerate approximate versions of the original unquantized values. like, glow-up but in reverse? ✨

And bestie, you can also override those with -min and -max if you wanna do your own thing. main character energy.

• Uses nrrdUnquantize 🫶

👑 OPTIONS 👑

• -i <nin>, --input <nin> — the input nrrd. ok so the tea here: this argument is required instead of optional, which is NOT how most unu(1) commands roll. that's a quirk caused by the need to have unu-unquantize(1) generate usage info, combined with the fact that all the other arguments have sensible defaults. so yeah, she's needy, but for a reason 💀
• -min <value>, --minimum <value> — defaults to nin->oldMin if it exists, otherwise 0.0 (double)
• -max <value>, --maximum <value> — defaults to nin->oldMax if it exists, otherwise 1.0 (double)
• -double — if you're not using -min or -max, this is whether to know the range of 8-bit data blindly (uchar is always [0,255], signed char is [-128,127]) (bool); default: “true”, "true" 👀
• -o <nout>, --output <nout> — output nrrd (string); default: “-”
