Public Types

typedef std::auto_ptr< SigmaMakerNoteAutoPtr
 Shortcut for a SigmaMakerNote auto pointer.

Public Member Functions

Creators
 SigmaMakerNote (bool alloc=true)
 Constructor. Allows to choose whether or not memory management is required for the makernote entries.
virtual ~SigmaMakerNote ()
 Virtual destructor.
Manipulators
int readHeader (const byte *buf, long len, ByteOrder byteOrder)
 Read the makernote header from the makernote databuffer. This method must set the offset adjustment (adjOffset_), if needed (assuming that the required information is in the header). Return 0 if successful.
Accessors
int checkHeader () const
 Check the makernote header. This will typically check if a required prefix string is present in the header. Return 0 if successful.
AutoPtr clone (bool alloc=true) const
 Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.
std::string ifdItem () const
 Return the name of the makernote item ("Sigma").
std::ostream & printTag (std::ostream &os, uint16_t tag, const Value &value) const
 Interpret and print the value of a makernote tag.

Static Public Member Functions

Print functions for Sigma (Foveon) MakerNote tags
std::ostream & printStripLabel (std::ostream &os, const Value &value)
 Strip the label from the value and print the remainder.
std::ostream & print0x0008 (std::ostream &os, const Value &value)
 Print exposure mode.
std::ostream & print0x0009 (std::ostream &os, const Value &value)
 Print metering mode.

MakerNote for Sigma (Foveon) cameras.


Member Function Documentation

int Exiv2::SigmaMakerNote::checkHeader  )  const [virtual]
 

Check the makernote header. This will typically check if a required prefix string is present in the header. Return 0 if successful.

Note:
The default implementation does nothing, assuming there is no header

Reimplemented from Exiv2::IfdMakerNote.

SigmaMakerNote::AutoPtr Exiv2::SigmaMakerNote::clone bool  alloc = true  )  const
 

Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Parameters:
alloc Memory management model for the clone. Indicates if memory required to store data should be allocated and deallocated (true) or not (false). If false, only pointers to the buffer provided to read() will be kept. See Ifd for more background on this concept.

Reimplemented from Exiv2::IfdMakerNote.

int Exiv2::SigmaMakerNote::readHeader const byte buf,
long  len,
ByteOrder  byteOrder
[virtual]
 

Read the makernote header from the makernote databuffer. This method must set the offset adjustment (adjOffset_), if needed (assuming that the required information is in the header). Return 0 if successful.

Note:
The default implementation does nothing, assuming there is no header
