ts-node-iptc

This module is based on the node-iptc: https://github.com/derekbaron/node-iptc The reason of this module is that node-iptc did not accept pull requests and does not have typescript type definitions available.

This module extracts IPTC information from JPEG files. IPTC is (mostly non-technical) structured metadata about the image with fields like creator/artist, copyright, keywords, category, etc.
