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

Detailed Description

Header of a Nikon 3 Makernote.

Member Function Documentation

baseOffset()

size_t Exiv2::Internal::Nikon3MnHeader::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.

byteOrder()

ByteOrder Exiv2::Internal::Nikon3MnHeader::byteOrder ( ) const

overridevirtual

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.

Reimplemented from Exiv2::Internal::MnHeader.

Referenced by setByteOrder(), and write().

ifdOffset()

size_t Exiv2::Internal::Nikon3MnHeader::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.

read()

bool Exiv2::Internal::Nikon3MnHeader::read ( const byte *  pData, size_t  size, ByteOrder  byteOrder  )

overridevirtual

Read the header from a data buffer, return true if ok.

Implements Exiv2::Internal::MnHeader.

setByteOrder()

void Exiv2::Internal::Nikon3MnHeader::setByteOrder ( ByteOrder  byteOrder )

overridevirtual

Set the byte order for the makernote.

Reimplemented from Exiv2::Internal::MnHeader.

References byteOrder().

size()

size_t Exiv2::Internal::Nikon3MnHeader::size ( ) const

overridevirtual

Return the size of the header (in bytes).

Implements Exiv2::Internal::MnHeader.

References sizeOfSignature().

Referenced by read().

write()

size_t Exiv2::Internal::Nikon3MnHeader::write ( IoWrapper &  ioWrapper, ByteOrder  byteOrder  ) const

overridevirtual

Write the header to a data buffer, return the number of bytes written.

Implements Exiv2::Internal::MnHeader.
