This processor relies on this metadata extractor library https://github.com/drewnoakes/metadata-extractor. It extracts a long list of metadata types including but not limited to EXIF, IPTC, XMP and Photoshop fields. For the full list visit the library's website.NOTE: The library being used loads the images into memory so extremely large images may cause problems.ExifExchangeableimagefileformatJPGGIFPNGBMPmetadataIPTCXMPMax Number of AttributesMax Number of AttributesSpecify the max number of attributes to add to the flowfile.

This processor relies on the Apache Tika project for file format detection and parsing. It extracts a long list of metadata types for media files including audio, video, and print media formats.NOTE: the attribute names and content extracted may vary across upgrades because parsing is performed by the external Tika tools which in turn depend on other projects for metadata extraction.
