gov.nih.mipav.model.file.MetadataExtractor.PhotoshopReader

All Implemented Interfaces:

MetadataExtractor.JpegSegmentMetadataReader

Enclosing class:

MetadataExtractor

public class MetadataExtractor.PhotoshopReader
extends Object
implements MetadataExtractor.JpegSegmentMetadataReader

Reads metadata created by Photoshop and stored in the APPD segment of JPEG files. Note that IPTC data may be stored within this segment, in which case this reader will create both a MetadataExtractor.PhotoshopDirectory and a

invalid reference

com.drew.metadata.iptc.IptcDirectory

.
