Method Details

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

public Long tryCustomProcessFormat(int tagId,
 int formatCode,
 long componentCount)

customProcessTag

public boolean customProcessTag(int tagOffset,
 Set<Integer> processedIfdOffsets,
 int tiffHeaderOffset,
 MetadataExtractor.RandomAccessReader reader,
 int tagId,
 int byteCount)
                         throws IOException

Throws:

IOException

processBinary

private void processBinary(MetadataExtractor.Directory directory,
 int tagValueOffset,
 MetadataExtractor.RandomAccessReader reader,
 int byteCount,
 Boolean isSigned,
 int arrayLength)
                    throws IOException

Throws:

IOException

getReaderString

private String getReaderString(MetadataExtractor.RandomAccessReader reader,
 int makernoteOffset,
 int bytesRequested)
                        throws 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:

IOException

processMakernote

private boolean processMakernote(int makernoteOffset,
 Set<Integer> processedIfdOffsets,
 int tiffHeaderOffset,
 MetadataExtractor.RandomAccessReader reader)
                          throws IOException

Throws:

IOException

                     throws IOException
