exif

@suaveplan/exif

Dependency-free, runtime-agnostic EXIF/XMP/IPTC metadata reader, writer, and stripper for JPEG and PNG images. Parses JPEG segment chains to locate and decode the EXIF IFD (TIFF byte-order aware, including GPS and SubIFD), IPTC IIM (caption, keywords, copyright), and XMP Dublin Core (raw XML string extraction). Writes back a revised EXIF IFD without re-encoding the image pixels, and strips all metadata segments for privacy-preserving image export. Includes a ByteReader/ByteWriter pair with rational arithmetic helpers and CRC-32 for PNG chunks. Use this package when you need to read camera metadata (make, model, GPS coordinates, orientation, focal length), watermark images with IPTC copyright fields, or scrub location data before publishing user-uploaded photos. For audio file metadata (ID3, MP4 atoms, FLAC Vorbis) use @suaveplan/metadata.

When to use this skill

• Implementing or debugging code that imports @suaveplan/exif.
• The task touches: see package README.
• You need API guidance for this package's exports.

Quick reference

import { /* see API Reference below */ } from "@suaveplan/exif";

Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. packages/media-core/exif/README.md — overview, install, quick-start, module index
2. packages/media-core/exif/src/**/*.md — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages in genesis ship ≥200 words per module)
3. packages/media-core/exif/package.json exports map — every subpath you can import from

When the user asks an API question, read the relevant co-located .md first; do not answer from training-data memory.
