✨ PTOHALVE ✨

okay bestie, welcome to the User Contributed Perl Documentation corner of the manual, and lemme tell you about ptohalve — the little tool that rescales a panorama project 💖

---

🌸 NAME 🌸

ptohalve — rescale a panorama project 🦋

---

💅 SYNOPSIS 💅

ptohalve [options] --output halved.pto project.pto

Options, babes:

• -o | --output — Filename of the scaled project. and yes it can be the the same as the input (that's literally what the original says, double "the" and all, no cap) 🙈
• -h | --help — Outputs help documentation 🎀

---

✨ DESCRIPTION ✨

So here's the tea ☕ — ptohalve takes a hugin .pto project and halves all pixel dimensions. periodt.

⚠️ but bestie, it will fail if any photos have non-even pixel dimensions. no half-pixels in this house 💀

If it succeeds, you will need to rescale the photos to match, like so:

mogrify -geometry 50% *.JPG

ngl, this tool is lowkey iconic when you use it in conjunction with the ptodouble tool, which performs the opposite transform 🔄 iykyk.
