Method Detail

• getSegmentTypes

  Iterable<JpegSegmentType> getSegmentTypes()

  Gets the set of JPEG segment types that this reader is interested in.

• canProcess

  boolean canProcess(byte[] segmentBytes,
                   JpegSegmentType segmentType)

  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.

• extract

  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.

  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.
