Static Public Member Functions

static void decode (CrwImage *pCrwImage, const byte *pData, uint32_t size)
 Decode metadata from a Canon CRW image in data buffer pData of length size into crwImage.

Detailed Description

Stateless parser class for Canon CRW images (Ciff format).

Member Function Documentation

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