getSegmentTypes

public Iterable<MetadataExtractor.JpegSegmentType> getSegmentTypes()

Description copied from interface: MetadataExtractor.JpegSegmentMetadataReader

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

Specified by:

getSegmentTypes in interface MetadataExtractor.JpegSegmentMetadataReader

readJpegSegments

public void readJpegSegments(Iterable<byte[]> segments,
 MetadataExtractor.Metadata metadata,
 MetadataExtractor.JpegSegmentType segmentType)

Description copied from interface: MetadataExtractor.JpegSegmentMetadataReader

Extracts metadata from all instances of a particular JPEG segment type.

Specified by:

readJpegSegments in interface MetadataExtractor.JpegSegmentMetadataReader

Parameters:

segments - A sequence of byte arrays from which the metadata should be extracted. These are in the order encountered in the original file.

metadata - The MetadataExtractor.Metadata object into which extracted values should be merged.

segmentType - The MetadataExtractor.JpegSegmentType being read.
