TAG_Y_CB_CR_POSITIONING

public static final 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.

Returns
double

getAttributeInt

public int getAttributeInt (String tag, 
                int defaultValue)

getAttributeRange

public long[] getAttributeRange (String tag)

Returns the offset and length of the requested tag inside the image file, or null if the tag is not contained.

Parameters
tag String

Returns
long[] two-element array, the offset in the first value, and length in the second, or null if no tag was found.
Throws
IllegalStateException if saveAttributes() has been called since the underlying file was initially parsed, since that means offsets may have changed.

getLatLong

public boolean getLatLong (float[] output)

This method is deprecated.
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

public 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

public 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

public byte[] getThumbnail ()

Returns
long[] two-element array, the offset in the first value, and length in the second, or null if no thumbnail was found or the thumbnail strips are not placed consecutively.
Throws
IllegalStateException if saveAttributes() has been called since the underlying file was initially parsed, since that means offsets may have changed.

Returns true if the image file has the given attribute defined.

Parameters
tag String: the name of the tag.

Returns
boolean

hasThumbnail

public boolean hasThumbnail ()

rotate

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
degree int: The degree of rotation.

saveAttributes

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(String, String) 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 files.

Note: after calling this method, any attempts to obtain range information from getAttributeRange(String) 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.

Throws
IOException

setAltitude

public void setAltitude (double altitude)

Sets the altitude in meters.

Parameters
altitude double

setAttribute

public void setAttribute (String tag, 
                String value)

Sets the value of the specified tag.

Parameters
tag String: the name of the tag.
value String: the value of the tag.

setGpsInfo

public void setGpsInfo (Location location)

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

public void setLatLong (double latitude, 
                double longitude)

Sets the latitude and longitude values.

Parameters

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