Static Public Member Functions
static void	decode (const CiffComponent &ciffComponent, Image &image, ByteOrder byteOrder)
	Decode image metadata from a CRW entry, convert and add it to the image metadata. This function converts only one CRW component. More...
static void	encode (CiffHeader *pHead, const Image &image)
	Encode image metadata from image into the CRW parse tree. This function converts all Exif metadata that Exiv2 can convert to CRW format, in a loop through the entries of the mapping table. More...
static void	loadStack (CrwDirs &crwDirs, uint16_t crwDir)
	Load the stack: loop through the CRW subdirs hierarchy and push all directories on the path from crwDir to root onto the stack crwDirs. Requires the subdirs array to be arranged in bottom-up order to be able to finish in only one pass.

decode()

void Exiv2::Internal::CrwMap::decode ( const CiffComponent &  ciffComponent, Image &  image, ByteOrder  byteOrder  )

static

Decode image metadata from a CRW entry, convert and add it to the image metadata. This function converts only one CRW component.

Parameters

ciffComponent	Source CIFF entry
image	Destination image for the metadata
byteOrder	Byte order in which the data of the entry is encoded

encode()

void Exiv2::Internal::CrwMap::encode ( CiffHeader *  pHead, const Image &  image  )

static

Encode image metadata from image into the CRW parse tree. This function converts all Exif metadata that Exiv2 can convert to CRW format, in a loop through the entries of the mapping table.

Parameters

pHead	Destination parse tree.
image	Source image containing the metadata.
