getSegmentTypes

public Iterable<JpegSegmentType> getSegmentTypes()

Description copied from interface: JpegSegmentMetadataReader

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

Specified by:

getSegmentTypes in interface JpegSegmentMetadataReader

readJpegSegments

public void readJpegSegments(Iterable<byte[]> segments,
 Metadata metadata,
