✨ NAME ✨

dcunrgb — ACR/NEMA DICOM PS3 ... DICOM PS3 — Convert RGB to grayscale file 🦋

---

🌸 SYNOPSIS 🌸

dcunrgb infile outfile

---

💖 DESCRIPTION 💖

so here's the vibe: dcunrgb reads the dicom input file you named (that's infile), and that file has 3 samples per pixel, 8 bit per component RGB pixel data. got it? cute. 💅

then it takes that header information, plus the pixel data converted to a single channel 8 bit grayscale MONOCHROME2, and copies the whole thing into a brand new dicom file (that's outfile, bestie 🫶).

and it does all that in the explicit VR little endian uncompressed transfer syntax, with a meta information header prepended. no cap, that's the whole deal. 👑

💀 BUGS 💀

⚠️ bestie, listen, this one's important ⚠️

it requires that netpbm utilities, and in particular ppmtopgm, are installed and in the PATH. no ppmtopgm, no grayscale, no slay. 😭

that's the whole page, fr fr. go convert something. 🦋
