decode()

int Exiv2::IptcParser::decode ( IptcData &  iptcData, const byte *  pData, uint32_t  size  )

static

Decode binary IPTC data in IPTC IIM4 format from a buffer pData of length size to the provided metadata container.

Parameters

iptcData	Metadata container to add the decoded IPTC datasets to.
pData	Pointer to the data buffer to read from.
size	Number of bytes in the data buffer.

Returns

0 if successful;
5 if the binary IPTC data is invalid or corrupt

encode()

DataBuf Exiv2::IptcParser::encode ( const IptcData &  iptcData )

static

Encode the IPTC datasets from iptcData to a binary representation in IPTC IIM4 format.

Convert the IPTC datasets to binary format and return it. Caller owns the returned buffer. The copied data follows the IPTC IIM4 standard.

Returns

Data buffer containing the binary IPTC data in IPTC IIM4 format.
