TAG_Y_CB_CR_COEFFICIENTS
String TAG_Y_CB_CR_COEFFICIENTS
The matrix coefficients for transformation from RGB to YCbCr image data. About the default value, please refer to JEITA CP-3451C Spec, Annex D.
- Tag = 529
- Type = Unsigned rational
- Count = 3
Constant Value: "YCbCrCoefficients"
TAG_Y_CB_CR_POSITIONING
String TAG_Y_CB_CR_POSITIONING
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
- Type = Unsigned short
- Count = 1
- Default =
Y_CB_CR_POSITIONING_CENTERED
Constant Value: "YCbCrPositioning"
TAG_Y_CB_CR_SUB_SAMPLING
String TAG_Y_CB_CR_SUB_SAMPLING
The sampling ratio of chrominance components in relation to the luminance component. In JPEG compressed data a JPEG marker is used instead of this tag. So, this tag shall not be recorded.
- Tag = 530
- Type = Unsigned short
- Count = 2
- [2, 1] = YCbCr4:2:2
- [2, 2] = YCbCr4:2:0
- Other = reserved
Constant Value: "YCbCrSubSampling"
TAG_Y_RESOLUTION
String TAG_Y_RESOLUTION
The number of pixels per TAG_RESOLUTION_UNIT
in the TAG_IMAGE_WIDTH
direction. The same value as TAG_X_RESOLUTION
shall be designated.
- Tag = 283
- Type = Unsigned rational
- Count = 1
- Default = 72

Public constructors
ExifInterface
ExifInterface (String filename)
Reads Exif tags from the specified image file.
Parameters | |
---|---|
filename |
String |
Throws | |
---|---|
IOException |
ExifInterface
ExifInterface (InputStream inputStream)
Reads Exif tags from the specified image input stream. Attribute mutation is not supported for input streams. The given input stream will proceed its current position. Developers should close the input stream after use. This constructor is not intended to be used with an input stream that performs any networking operations.
Parameters | |
---|---|
inputStream |
InputStream |
Throws | |
---|---|
IOException |
Public methods
getAltitude
double getAltitude (double defaultValue)
Return the altitude in meters. If the exif tag does not exist, return defaultValue.
Parameters | |
---|---|
defaultValue |
double : the value to return if the tag is not available.
|
Returns | |
---|---|
double |
getAttribute
String getAttribute (String tag)
Returns the value of the specified tag or null
if there
is no such tag in the image file.
Parameters | |
---|---|
tag |
String : the name of the tag.
|
Returns | |
---|---|
String |
getAttributeDouble
double getAttributeDouble (String tag, double defaultValue)
Returns the double value of the tag that is specified as rational or contains a double-formatted value. If there is no such tag in the image file or the value cannot be parsed as double, return defaultValue.
Parameters | |
---|---|
tag |
String : the name of the tag. |
defaultValue |
double : the value to return if the tag is not available.
|
Returns | |
---|---|
double |
getAttributeInt
int getAttributeInt (String tag, int defaultValue)
Returns the integer value of the specified tag. If there is no such tag in the image file or the value cannot be parsed as integer, return defaultValue.
Parameters | |
---|---|
tag |
String : the name of the tag. |
defaultValue |
int : the value to return if the tag is not available.
|
Returns | |
---|---|
int |
getLatLong
boolean getLatLong (float[] output)
This method was deprecated
in API level 25.4.0.
Use getLatLong()
instead.
Stores the latitude and longitude value in a float array. The first element is the latitude, and the second element is the longitude. Returns false if the Exif tags are not available.
Parameters | |
---|---|
output |
float |
Returns | |
---|---|
boolean |
getLatLong
double[] getLatLong ()
Gets the latitude and longitude values.
If there are valid latitude and longitude values in the image, this method returns a double array where the first element is the latitude and the second element is the longitude. Otherwise, it returns null.
Returns | |
---|---|
double[] |
getRotationDegrees
int getRotationDegrees ()
Returns the rotation degrees for the current image orientation. If the image is flipped,
i.e., isFlipped()
returns true
, the rotation degrees will be base on
the assumption that the image is first flipped horizontally (along Y-axis), and then do
the rotation. For example, ORIENTATION_TRANSPOSE
will be interpreted as flipped
horizontally first, and then rotate 270 degrees clockwise.
Returns | |
---|---|
int |
The rotation degrees of the image after the horizontal flipping is applied, if any. |

getThumbnail
byte[] getThumbnail ()
Returns the JPEG compressed thumbnail inside the image file, or null
if there is no
JPEG compressed thumbnail.
The returned data can be decoded using
decodeByteArray(byte[], int, int)
Returns | |
---|---|
byte[] |
getThumbnailBitmap
Bitmap getThumbnailBitmap ()
Creates and returns a Bitmap object of the thumbnail image based on the byte array and the
thumbnail compression value, or null
if the compression type is unsupported.
Returns | |
---|---|
Bitmap |
getThumbnailBytes
byte[] getThumbnailBytes ()
Returns the thumbnail bytes inside the image file, regardless of the compression type of the thumbnail image.
Returns | |
---|---|
byte[] |
getThumbnailRange
long[] getThumbnailRange ()
Returns the offset and length of thumbnail inside the image file, or
null
if there is no thumbnail.
Returns | |
---|---|
long[] |
two-element array, the offset in the first value, and length in
the second, or null if no thumbnail was found.
|
hasThumbnail
boolean hasThumbnail ()
Returns true if the image file has a thumbnail.
Returns | |
---|---|
boolean |
isFlipped
boolean isFlipped ()
Returns if the current image orientation is flipped.
Returns | |
---|---|
boolean |
See also:
isThumbnailCompressed

Returns | |
---|---|
boolean |
resetOrientation
void resetOrientation ()
Resets the TAG_ORIENTATION
of the image to be ORIENTATION_NORMAL
.
rotate
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 | |
---|---|
degree |
int : The degree of rotation.
|
saveAttributes
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(String, String)
to set all attributes to write
and make a single call rather than multiple calls for each attribute.
This method is only supported for JPEG files.
Throws | |
---|---|
IOException |
setAltitude

---|---|
tag |
String : the name of the tag. |
value |
String : the value of the tag.
|

Sets the GPS-related information. It will set GPS processing method, latitude and longitude values, GPS timestamp, and speed information at the same time.
Parameters | |
---|---|
location |
Location : the Location object returned by GPS service.
|
setLatLong
void setLatLong (double latitude, double longitude)
