Class IFDEntry

Minimum version

1.0.0

Minimum environment

Java 17

Description

A class that represents each entry in an Image File Directory (IFD).

Constructor

Signatures

public IFDEntry(int baseOffset, byte[] data, int offset, boolean intelOrder)

Parameters

Name	Type	Description
baseOffset	int	TIFF header start position
data	byte[]	Byte array
offset	int	Starting position representing the IFDEntry
intelOrder	boolean	Set to true if the byte order of the data is little endian or false if it is big endian.

Uses

IFDEntry entry = new IFDEntry(baseoffset, data, offset, true);

Methods

getDataInt

Returns the value of each Entry in the Image File Directory (IFD) as an integer.
Signatures
```
public int getDataInt()
```
Return

Integer values
Note 1) Even for SLONG type, it is returned as a signed integer (4 bytes).
Note 2) If the type is ASCII, RATIONAL, SRATIONAL, UNDEFINED, an error occurs when calling this method.
Note 3) This method reads only the default size of the dextuploadjk.media.ImageMetadata.IFDDataFormat format and returns it as an integer.

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getDataInt();
    ...
}

getDataDouble

Returns the value of each entry in the IFD (Image File Directory) as a double-precision floating point.
Signatures
```
public double getDataDouble()
```
Return

Double precision floating point value.
Note 1) If you call this method with ASCII or UNDEFINED type, an error occurs.
Note 2) This method reads only the default size of the dextuploadjk.media.ImageMetadata.IFDDataFormat format and returns it as a double precision floating point value.

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getDataDouble();
    ...
}

getDataString

Returns the value of each Entry in the Image File Directory (IFD) as a string.
Signatures
```
public String getDataString()
```
Return

The string
Note 1) In case of fractional type, it is returned in 'numerator/denominator' format.
Note 2) If the length is longer than the size of dextuploadjk.media.ImageMetadata.IFDDataFormat, it is separated by ',' characters.

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getDataString();
    ...
}

getOffset

Returns the start position of each entry in the Image File Directory (IFD).
The start position is relative to the start position of the TIFF header.
Signatures
```
public int getOffset()
```
Return

Start position

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getOffset();
    ...
}

getTag

Returns the dextuploadjk.media.ImageMetadata.Tag value for each entry in the Image File Directory (IFD).
Signatures
```
public media.ImageMetadata.Tag getTag()
```
Return

dextuploadjk.media.ImageMetadata.Tag value
Note) If the Tag is unknown or not supported, null is returned.

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getTag();
    ...
}

getDataFormat

Returns the dextuploadjk.media.ImageMetadata.IFDDataFormat format of the value for each Entry in the Image File Directory (IFD).
Signatures
```
public IFDDataFormat getDataFormat()
```
Return

dextuploadjk.media.ImageMetadata.IFDDataFormat value

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getDataFormat();
    ...
}

getComponentNumber

Returns the number of components each entry in the Image File Directory (IFD) has.
Signatures
```
public int getComponentNumber()
```
Return

Component count

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getComponentNumber();
    ...
}

getEntry

Returns the value of each entry in the Image File Directory (IFD) as a byte array.
Signatures
```
public byte[] getEntry()
```
Return

Byte array

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getEntry();
    ...
}

getDataLength

Returns the length of the value for each entry in the Image File Directory (IFD).
This length is the size of the dextuploadjk.media.ImageMetadata.IFDDataFormat format multiplied by the number of components.
Signatures
```
public int getDataLength()
```
Return

The length of the value for each entry in the Image File Directory (IFD).

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getDataLength();
    ...
}

getTagNumber

Returns the dextuploadjk.media.ImageMetadata.Tag value of each entry in the Image File Directory (IFD) as an integer.
Signatures
```
public int getTagNumber()
```
Return

Integer dextuploadjk.media.ImageMetadata.Tag value

Uses

ImageMetadata metadata = oimg.getMetadata();			
    ...
for (IFDEntry entry : metadata.getExif()) {
	entry.getTagNumber();
    ...
}
