Creators

Manipulators
virtual bool	read (const byte *pData, size_t size, ByteOrder byteOrder)=0
	Read the header from a data buffer, return true if ok.
virtual void	setByteOrder (ByteOrder byteOrder)
	Set the byte order for the makernote.
Accessors
virtual size_t	size () const =0
	Return the size of the header (in bytes).
virtual size_t	write (IoWrapper &ioWrapper, ByteOrder byteOrder) const =0
	Write the header to a data buffer, return the number of bytes written.
virtual size_t	ifdOffset () const
	Return the offset to the start of the Makernote IFD from the start of the Makernote (= the start of the header).
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.
virtual size_t	baseOffset (size_t mnOffset) const
	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.

Detailed Description

Member Function Documentation

baseOffset()

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

virtual

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 in Exiv2::Internal::Olympus2MnHeader, Exiv2::Internal::OMSystemMnHeader, Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon3MnHeader, Exiv2::Internal::PentaxDngMnHeader, and Exiv2::Internal::SamsungMnHeader.

byteOrder()

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

virtual

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 in Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon3MnHeader, and Exiv2::Internal::Casio2MnHeader.

ifdOffset()

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

virtual

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

Reimplemented in Exiv2::Internal::OlympusMnHeader, Exiv2::Internal::Olympus2MnHeader, Exiv2::Internal::OMSystemMnHeader, Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon2MnHeader, Exiv2::Internal::Nikon3MnHeader, Exiv2::Internal::PanasonicMnHeader, Exiv2::Internal::PentaxDngMnHeader, Exiv2::Internal::PentaxMnHeader, Exiv2::Internal::SigmaMnHeader, Exiv2::Internal::SonyMnHeader, and Exiv2::Internal::Casio2MnHeader.

read()

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

pure virtual

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

Implemented in Exiv2::Internal::OlympusMnHeader, Exiv2::Internal::Olympus2MnHeader, Exiv2::Internal::OMSystemMnHeader, Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon2MnHeader, Exiv2::Internal::Nikon3MnHeader, Exiv2::Internal::PanasonicMnHeader, Exiv2::Internal::PentaxDngMnHeader, Exiv2::Internal::PentaxMnHeader, Exiv2::Internal::SamsungMnHeader, Exiv2::Internal::SigmaMnHeader, Exiv2::Internal::SonyMnHeader, and Exiv2::Internal::Casio2MnHeader.

setByteOrder()

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

virtual

Set the byte order for the makernote.

Reimplemented in Exiv2::Internal::Nikon3MnHeader.

size()

virtual size_t Exiv2::Internal::MnHeader::size ( ) const

pure virtual

Return the size of the header (in bytes).

Implemented in Exiv2::Internal::OlympusMnHeader, Exiv2::Internal::Olympus2MnHeader, Exiv2::Internal::OMSystemMnHeader, Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon2MnHeader, Exiv2::Internal::Nikon3MnHeader, Exiv2::Internal::PanasonicMnHeader, Exiv2::Internal::PentaxDngMnHeader, Exiv2::Internal::PentaxMnHeader, Exiv2::Internal::SamsungMnHeader, Exiv2::Internal::SigmaMnHeader, Exiv2::Internal::SonyMnHeader, and Exiv2::Internal::Casio2MnHeader.

write()

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

pure virtual

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

Implemented in Exiv2::Internal::OlympusMnHeader, Exiv2::Internal::Olympus2MnHeader, Exiv2::Internal::OMSystemMnHeader, Exiv2::Internal::FujiMnHeader, Exiv2::Internal::Nikon2MnHeader, Exiv2::Internal::Nikon3MnHeader, Exiv2::Internal::PanasonicMnHeader, Exiv2::Internal::PentaxDngMnHeader, Exiv2::Internal::PentaxMnHeader, Exiv2::Internal::SamsungMnHeader, Exiv2::Internal::SigmaMnHeader, Exiv2::Internal::SonyMnHeader, and Exiv2::Internal::Casio2MnHeader.
