An interface to extract information from XMP metadata.

Implementations

impl Xmp

pub fn from_data(_xmp_data: &Data) -> Self

Create from XMP data.

pub fn from_extended(_xmp_standard: &Data, _xmp_extended: &Data) -> Self

Create from standard XMP + extended XMP data.

see XMP Specification Part 3: Storage in files, Section 1.1.3.1: Extended XMP in JPEG

pub fn get_gainmap_info_hdrgm(&self, _info: &mut GainmapInfo) -> bool

Extract HDRGM gainmap parameters.

pub fn get_gainmap_info_hdr_gain_map(&self, _info: &mut GainmapInfo) -> bool

Extract HDRGainMap gainmap parameters.

pub fn get_container_gainmap_location( &self, _offset: &mut usize, _size: &mut usize ) -> bool

If this includes GContainer metadata and the GContainer contains an item with semantic GainMap and Mime of image/jpeg, then return true, and populate |offset| and |size| with that item’s offset (from the end of the primary JPEG image’s EndOfImage), and the size of the gainmap.

pub fn get_extended_xmp_guid(&self) -> String

Return the GUID of an Extended XMP if present, or null otherwise.
