Method Detail
-
setTiffMarker
public void setTiffMarker(int marker) throws MetadataExtractor.TiffProcessingExceptionDescription copied from interface:MetadataExtractor.TiffHandlerReceives 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 java.lang.Long tryCustomProcessFormat(int tagId, int formatCode, long componentCount)
-
customProcessTag
public boolean customProcessTag(int tagOffset, java.util.Set<java.lang.Integer> processedIfdOffsets, int tiffHeaderOffset, MetadataExtractor.RandomAccessReader reader, int tagId, int byteCount) throws java.io.IOException- Throws:

-
processBinary
private void processBinary(MetadataExtractor.Directory directory, int tagValueOffset, MetadataExtractor.RandomAccessReader reader, int byteCount, java.lang.Boolean isSigned, int arrayLength) throws java.io.IOException
- Throws:

-
getReaderString
private java.lang.String getReaderString(MetadataExtractor.RandomAccessReader reader, int makernoteOffset, int bytesRequested) 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
-
processMakernote
