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.
HEIF
- If XMP is present in both Exif and separate segments, the XMP from the Exif segment is returned from getAttributeBytes.

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.

The Interoperability copyright statement including date and rights should be written in this field; e.g., "Copyright, John Smith, 19xx. All rights reserved." In this standard the field records both the photographer and editor copyrights, with each recorded in a separate part of the statement. When there is a clear distinction between the photographer and editor copyrights, these are to be written in the order of photographer followed by editor copyright, separated by NULL (in this case, since the statement also ends with a NULL, there are two NULL codes) (see example 1). When only the photographer copyright is given, it is terminated by one NULL code (see example 2). When only the editor copyright is given, the photographer copyright part consists of one space followed by a terminating NULL code, then the editor copyright is given (see example 3). When the field is left blank, it is treated as unknown.

TAG_Y_CB_CR_POSITIONING

Added in 1.0.0

public static final String TAG_Y_CB_CR_POSITIONING = "YCbCrPositioning"

The position of chrominance components in relation to the luminance component. This field is designated only for JPEG compressed data or uncompressed YCbCr data. The TIFF default is Y_CB_CR_POSITIONING_CENTERED; but when Y:Cb:Cr = 4:2:2 it is recommended in this standard that Y_CB_CR_POSITIONING_CO_SITED be used to record data, in order to improve the image quality when viewed on TV systems. When this field does not exist, the reader shall assume the TIFF default. In the case of Y:Cb:Cr = 4:2:0, the TIFF default (Y_CB_CR_POSITIONING_CENTERED) is recommended. If the Exif/DCF reader does not have the capability of supporting both kinds of positioning, it shall follow the TIFF default regardless of the value in this field. It is preferable that readers can support both centered and co-sited positioning.

Tag = 531

Added in 1.0.0

public void rotate(int degree)

Rotates the image by the given degree clockwise. The degree should be a multiple of 90 (e.g, 90, 180, -90, etc.).

Parameters
`int degree`	The degree of rotation.

saveAttributes

Added in 1.0.0

public void saveAttributes()

Save the tag data into the original image file. This is expensive because it involves copying all the data from one file to another and deleting the old file and renaming the other. It's best to use setAttribute to set all attributes to write and make a single call rather than multiple calls for each attribute.

This method is supported for JPEG, PNG, and WebP formats.

Note: after calling this method, any attempts to obtain range information from getAttributeRange or getThumbnailRange will throw IllegalStateException, since the offsets may have changed in the newly written file.

For WebP format, the Exif data will be stored as an Extended File Format, and it may not be supported for older readers.

For PNG format, the Exif data will be stored as an "eXIf" chunk as per "Extensions to the PNG 1.2 Specification, Version 1.5.0".

Throws
`java.io.IOException`

setAltitude

setLatLong

Added in 1.0.0

public void setLatLong(double latitude, double longitude)

Sets the latitude and longitude values.

Parameters
`double latitude`	the decimal value of latitude. Must be a valid double value between -90.0 and 90.0.
`double longitude`	the decimal value of longitude. Must be a valid double value between -180.0 and 180.0.

Throws
`java.lang.IllegalArgumentException`	If `latitude` or `longitude` is outside the specified range.
