Methods
Modifier and Type	Method and Description
`boolean`	`canProcess(byte[] segmentBytes, JpegSegmentType segmentType)` Gets a value indicating whether the supplied byte data can be processed by this reader.
`void`	`extract(byte[] segmentBytes, Metadata metadata, JpegSegmentType segmentType)` Extracts metadata from a JPEG segment's byte array and merges it into the specified `Metadata` object.
`void`	`extract(SequentialReader reader, Metadata metadata, long length)` Performs the IPTC data extraction, adding found values to the specified instance of `Metadata`.
`Iterable<JpegSegmentType>`	`getSegmentTypes()` Gets the set of JPEG segment types that this reader is interested in.

    Description copied from interface: JpegSegmentMetadataReader
    
    Gets the set of JPEG segment types that this reader is interested in.
    
    Specified by:
    
    getSegmentTypes in interface JpegSegmentMetadataReader
  - canProcess
```
public boolean canProcess(byte[] segmentBytes,
                 JpegSegmentType segmentType)
```
    Description copied from interface: JpegSegmentMetadataReader
    
    Gets a value indicating whether the supplied byte data can be processed by this reader. This is not a guarantee that no errors will occur, but rather a best-effort indication of whether the parse is likely to succeed. Implementations are expected to check things such as the opening bytes, data length, etc.
    
    Specified by:

  - extract
```
public void extract(byte[] segmentBytes,
           Metadata metadata,
           JpegSegmentType segmentType)
```
    Description copied from interface: JpegSegmentMetadataReader
    
    Extracts metadata from a JPEG segment's byte array and merges it into the specified Metadata object.
    
    Specified by:
    
    extract in interface JpegSegmentMetadataReader
    
    Parameters:
    segmentBytes - The byte array from which the metadata should be extracted.
    metadata - The Metadata object into which extracted values should be merged.
    segmentType - The JpegSegmentType being read.
  - extract
```
public void extract(SequentialReader reader,
           Metadata metadata,
           long length)
```
    Performs the IPTC data extraction, adding found values to the specified instance of Metadata.
