Member Function Documentation

int Exiv2::Photoshop::locateIrb (  const byte *  pPsData, long  sizePsData, uint16_t  psTag, const byte **  record, uint32_t *const   sizeHdr, uint32_t *const   sizeData )  [static]

Locates the data for a Photoshop tag in a Photoshop formated memory buffer. Operates on raw data to simplify reuse. Parameters: pPsData  Pointer to buffer containing entire payload of Photoshop formated data, e.g., from APP13 Jpeg segment. sizePsData  Size in bytes of pPsData. psTag  Tag number of the block to look for. record  Output value that is set to the start of the data block within pPsData (may not be null). sizeHdr  Output value that is set to the size of the header within the data block pointed to by record (may not be null). sizeData  Output value that is set to the size of the actual data within the data block pointed to by record (may not be null). Returns: 0 if successful; 3 if no data for psTag was found in pPsData; -2 if the pPsData buffer does not contain valid data.

DataBuf Exiv2::Photoshop::setIptcIrb (  const byte *  pPsData, long  sizePsData, const IptcData &  iptcData )  [static]

Set the new IPTC IRB, keeps existing IRBs but removes the IPTC block if there is no new IPTC data to write. Parameters: pPsData  Existing IRB buffer sizePsData  Size of the IRB buffer, may be 0 iptcData  Iptc data to embed, may be empty Returns: A data buffer containing the new IRB buffer, may have 0 size
