💅 flipx — bestie edition ✨

ok so like, welcome to flipx(1), the General Commands Manual entry that's about to be your new hyperfixation 🫶

🌸 NAME 🌸

flipx — flip the x axis in a FITS image, no cap 💖

✨ SYNOPSIS ✨

flipx <input images>

🦋 DESCRIPTION 🦋

okay so bestie, listen — this program is literally an example of how to use the qfits library 🎀. That's its whole main character moment, and it ate.

It wants a list of FITS file names on input, like a little lineup of files waiting for their glow-up 💅.

For every single input file, it takes the image sitting in the main data section and flips it in the X direction — meaning pixel (i,j) gets swapped with pixel (lx-i, j). periodt. 🔥

Now the pixel loading mechanism? It's independent from the endian-ness of the local host AND independent from the FITS pixel type. So it does not care what your machine's vibe is or what pixel type you rolled up with — iconic, honestly. That's why this program gives you a really good overview of how to use qfits for pixel-level operations ✨. iykyk.

💜 OPTIONS 💜

  • None. — that's it, that's the list. no flags, no extras, just vibes 🧚

🍓 FILES 🍓

Input files shall all comply with FITS format. no exceptions bestie, the FITS format is non-negotiable 🎀

💀 BUGS 💀

not me exposing the flaws but okay 🙈

Heads up: this program does NOT support cubes or image extensions 😭. Like, at all. BUT — and this is the slay part — it could be easily extended to support that case 👑. So if you're feeling ambitious, go off, the door is open ✨.
