ExifInterface

class ExifInterface


This is a class for reading and writing Exif tags in various image file formats.

Supported for reading: JPEG, PNG, WebP, HEIF, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW, RAF.

Supported for writing: JPEG, PNG, WebP.

Note: JPEG and HEIF files may contain XMP data either inside the Exif data chunk or outside of it. This class will search both locations for XMP data, but if XMP data exist both inside and outside Exif, will favor the XMP data inside Exif over the one outside.
