✨ PTOCHAIN(1) ✨

okay bestie, so this is a page from the User Contributed Perl Documentation collection, and it's about a lil tool called ptochain 💖

🌸 NAME 🌸

ptochain — adds control points to a Hugin project between consecutive photos 🦋

like, it goes in and hooks up your photos to each other, one after the next, no cap.

🎀 SYNOPSIS 🎀

ptochain [options] --output output.pto input.pto

and here's the options list, bestie:

 Options:
  -m | --makefile file  Output Makefile
  -o | --output file    Output project
  -h | --help           Outputs help documentation.

💅 DESCRIPTION 💅

so ptochain is basically a wrapper around a bunch of other tools that generate control points, and the whole thing outputs a .pto project 🫶

Consecutive photos in the project get picked for feature matching, and then they're connected into one or more chains of connected images. it's giving ✨friend group✨ energy, everyone gets linked up.

and here's the iconic part: if points already exist between photos, then matching gets skipped — meaning this tool is a literal noop if a full set of control points already exists in the project 🙈 like, nothing to do here, already slayed.

if you pass the --makefile option, the rules for generating the project get written to a Makefile. but if --makefile isn't set, then those rules get executed immediately 🏃‍♀️💨

Control point generator parameters are set via Option lines in the input project, like so:

  #hugin_cpgenSize 1500
  #hugin_cpgenNumber 25
  #hugin_cpgenRansac true
  #hugin_cpgenRefine false
ngl those #hugin_cpgen* lines are your little levers, set them in the input project and the generator listens 👑
