virtual void	setByteOrder (ByteOrder byteOrder)
	Set the byte order for the makernote.
virtual ByteOrder	byteOrder () const
	Return the byte order for the makernote. If the return value is invalidByteOrder, this means that the byte order of the the image should be used for the makernote.

Accessors

	Write the header to a data buffer, return the number of bytes written.
size_t	ifdOffset () const override
	Return the offset to the start of the Makernote IFD from the start of the Makernote (= the start of the header).
size_t	baseOffset (size_t mnOffset) const override
	Return the base offset for the makernote IFD entries relative to the start of the TIFF header. mnOffset is the offset to the makernote from the start of the TIFF header.
static size_t	sizeOfSignature ()
	Return the size of the makernote header signature.

baseOffset()

size_t Exiv2::Internal::Olympus2MnHeader::baseOffset ( size_t  mnOffset ) const

overridevirtual

Return the base offset for the makernote IFD entries relative to the start of the TIFF header. mnOffset is the offset to the makernote from the start of the TIFF header.

Reimplemented from Exiv2::Internal::MnHeader.

ifdOffset()

size_t Exiv2::Internal::Olympus2MnHeader::ifdOffset ( ) const

overridevirtual

Return the offset to the start of the Makernote IFD from the start of the Makernote (= the start of the header).

Reimplemented from Exiv2::Internal::MnHeader.
