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

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.
