Constructor Detail

ExifTiffHandler

public ExifTiffHandler(MetadataExtractor.Metadata metadata,
                       MetadataExtractor.Directory parentDirectory)

Method Detail

setTiffMarker

public void setTiffMarker(int marker)
                   throws MetadataExtractor.TiffProcessingException

Description copied from interface: MetadataExtractor.TiffHandler

Receives the 2-byte marker found in the TIFF header.

Implementations are not obligated to use this information for any purpose, though it may be useful for validation or perhaps differentiating the type of mapping to use for observed tags and IFDs.

Parameters:

marker - the 2-byte value found at position 2 of the TIFF header

Throws:

MetadataExtractor.TiffProcessingException

tryEnterSubIfd

public boolean tryEnterSubIfd(int tagId)

hasFollowerIfd

public boolean hasFollowerIfd()

tryCustomProcessFormat

                                             long componentCount)

customProcessTag

public boolean customProcessTag(int tagOffset,
                                java.util.Set<java.lang.Integer> processedIfdOffsets,
                                int tiffHeaderOffset,

Throws:

                                  throws java.io.IOException

Read a given number of bytes from the stream This method is employed to "suppress" attempts to read beyond end of the file as may happen at the beginning of processMakernote when we read increasingly longer camera makes. Instead of failing altogether in this context we return an empty string a full-on failure.

Throws:

java.io.IOException
