void Exiv2::CrwParser::decode	(	CrwImage *	pCrwImage,
		const byte *	pData,
		uint32_t	size
	)			[static]

Decode metadata from a Canon CRW image in data buffer pData of length size into crwImage.

This is the entry point to access image data in Ciff format. The parser uses classes CiffHeader, CiffEntry, CiffDirectory.

Parameters:

pCrwImage

Pointer to the Exiv2 CRW image to hold the metadata read from the buffer. Parameters: pData  Pointer to the data buffer. Must point to the data of a CRW image; no checks are performed. Parameters: size  Length of the data buffer. Exceptions: Error  If the data buffer cannot be parsed.

void Exiv2::CrwParser::encode	(	Blob &	blob,
		const byte *	pData,
		uint32_t	size,
		const CrwImage *	pCrwImage
	)			[static]

Encode metadata from the CRW image into a data buffer (the binary CRW image).

Parameters:

blob

Data buffer for the binary image (target). Parameters: pData  Pointer to the binary image data buffer. Must point to data in CRW format; no checks are performed. Parameters: size  Length of the data buffer. Parameters: pCrwImage  Pointer to the Exiv2 CRW image with the metadata to encode. Exceptions: Error  If the metadata from the CRW image cannot be encoded.
