ExifInterface

Artifact: androidx.exifinterface:exifinterface

Added in 1.0.0

Kotlin |Java

public class ExifInterface

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

Supported for reading: JPEG, PNG, WebP, HEIC, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW, RAF, AVIF (on API 31+).

Supported for writing: JPEG, PNG, WebP.

XMP Support

This class can read raw XMP data from the supported image file formats.

XMP data can be stored within Exif data (under tag 700), but many of the formats also define a separate storage location for XMP. ExifInterface handles this ambiguity as follows:

JPEG
- The XMP spec part 3 section 3.3.2 forbids the XMP tag (700) being present in the Exif segment of JPEG files (i.e. XMP should always be in a separate APP1 segment).
- If XMP is present in both Exif and separate segments, the XMP from the Exif segment is returned from getAttributeBytes and modifications to the XMP with setAttribute are written back to the XMP in the Exif segment, the XMP in the separate segment is preserved unmodified. This is contrary to the spec described above (which suggests the standalone XMP should be preferred over the XMP in the Exif segment).
- If XMP is not present in either location, and is added with setAttribute, it is written as a standalone segment, in line with the spec described above.
HEIC &AVIF
- If XMP is present in both Exif and separate segments, the XMP from the separate segment is returned from getAttributeBytes.
