Fields

item_type: FourCC

An instance of FourCC indicating the type of the metadata, as specified in the HEIF file.

Exif data will have the type b"Exif".

content_type: String

For EXIF, the content type is "".

For XMP, the content type is "application/rdf+xml".

uri_type: String

An absolute URI. Only valid for item_type == “uri”.

raw_data: Vec<u8>

The data is exactly as stored in the HEIF file.

For Exif data, you probably have to skip the first four bytes of the data, since they indicate the offset to the start of the TIFF header of the Exif data.
