Class JpegExif

java.lang.Object

edu.harvard.hul.ois.jhove.module.jpeg.JpegExif

public final class JpegExif
extends Object

Reader of Exif data embedded in a JPEG App1 block. This makes use of the TIFF module, since an Exif stream is really an embedded TIFF file; but it is designed to fail cleanly if the TIFF module is absent.

                            int length)

Reads the Exif data from the current point at the data stream, puts it into a temporary file, and makes a RepInfo object available. This should be called only if isTiffAvailable() has returned true.

isExifProfileOK

public boolean isExifProfileOK()

Returns true if the Exif IFD is present and satisfies the profile requirements.

getProfileText

public String getProfileText()

Returns the text which describes the exif profile.

getExifNiso

public NisoImageMetadata getExifNiso()
