Description copied from interface: 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:

TiffProcessingException
