Image::...anonRaw(3)

💖 NAME 💖

Image::ExifTool::WriteCanonRaw.pl — bestie, this is the file that lets you write Canon RAW info, as in CRW and CR2. It's part of the Image::...anonRaw(3) manual page, and it's giving very "under the hood but make it slay" energy. 🎀

---

✨ SYNOPSIS ✨

So like, you don't call these yourself, okay? These routines get autoloaded by Image::ExifTool::CanonRaw. It's giving "I don't need an invitation, I just show up when I'm needed." 💅

---

🌸 DESCRIPTION 🌸

This file has the routines that ExifTool uses to write Canon CRW and CR2 files and metadata. That's it, that's the whole vibe. 🦋

---

👑 NOTES 👑

Okay so real talk: the CRW format is a pleasure to work with. No cap. 😭✨

Here's the tea: all pointer offsets are relative to the start of the data for each directory. That's it. That's the design.

And like… imagine if EXIF/TIFF had done pointers this way?? It would be MUCH easier to read and write TIFF and JPEG files, and there would be far fewer problems with corrupted metadata. The way they fumbled that one… 💀
