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.
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.
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.

Parameters:

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

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.
