Public Member Functions | |
Manipulators | |
| int | load (const byte *buf, long len) |
| Load the IPTC data from a byte buffer. The format must follow the IPTC IIM4 standard. | |
| Iptcdatum & | operator[] (const std::string &key) |
| Returns a reference to the Iptcdatum that is associated with a particular key. If IptcData does not already contain such an Iptcdatum, operator[] adds object Iptcdatum(key). | |
| int | add (const IptcKey &key, Value *value) |
| Add an Iptcdatum from the supplied key and value pair. This method copies (clones) the value. A check for non-repeatable datasets is performed. | |
| int | add (const Iptcdatum &iptcdatum) |
| Add a copy of the Iptcdatum to the IPTC metadata. A check for non-repeatable datasets is performed. | |
| iterator | erase (iterator pos) |
| Delete the Iptcdatum at iterator position pos, return the position of the next Iptcdatum. Note that iterators into the metadata, including pos, are potentially invalidated by this call. | |
| void | clear () |
| Delete all Iptcdatum instances resulting in an empty container. | |
| void | sortByKey () |
| Sort metadata by key. | |
| void | sortByTag () |
| Sort metadata by tag (aka dataset). | |
| iterator | begin () |
| Begin of the metadata. | |
| iterator | end () |
| End of the metadata. | |
| iterator | findKey (const IptcKey &key) |
| Find the first Iptcdatum with the given key, return an iterator to it. | |
| iterator | findId (uint16_t dataset, uint16_t record=IptcDataSets::application2) |
| Find the first Iptcdatum with the given record and dataset it, return a const iterator to it. | |
Accessors | |
| const_iterator | begin () const |
| Begin of the metadata. | |
| const_iterator | end () const |
| End of the metadata. | |
| DataBuf | copy () const |
| Write the IPTC data to a data buffer and return the data buffer. Caller owns this buffer. The copied data follows the IPTC IIM4 standard. | |
| const_iterator | findKey (const IptcKey &key) const |
| Find the first Iptcdatum with the given key, return a const iterator to it. | |
| const_iterator | findId (uint16_t dataset, uint16_t record=IptcDataSets::application2) const |
| Find the first Iptcdatum with the given record and dataset number, return a const iterator to it. | |
| bool | empty () const |
| Return true if there is no IPTC metadata. | |
| long | count () const |
| Get the number of metadata entries. | |
| long | size () const |
| Return the exact size of all contained IPTC metadata. | |
Provide high-level access to the IPTC data of an image:
iptceasy.cpp, and iptcprint.cpp.
| int Exiv2::IptcData::load | ( | const byte * | buf, | |
| long | len | |||
| ) |
Load the IPTC data from a byte buffer. The format must follow the IPTC IIM4 standard.
| buf | Pointer to the data buffer to read from | |
| len | Number of bytes in the data buffer |
| Iptcdatum& Exiv2::IptcData::operator[] | ( | const std::string & | key | ) |
Returns a reference to the Iptcdatum that is associated with a particular key. If IptcData does not already contain such an Iptcdatum, operator[] adds object Iptcdatum(key).
Add an Iptcdatum from the supplied key and value pair. This method copies (clones) the value. A check for non-repeatable datasets is performed.
| int Exiv2::IptcData::add | ( | const Iptcdatum & | iptcdatum | ) |
Add a copy of the Iptcdatum to the IPTC metadata. A check for non-repeatable datasets is performed.
| DataBuf Exiv2::IptcData::copy | ( | ) | const |
Write the IPTC data to a data buffer and return the data buffer. Caller owns this buffer. The copied data follows the IPTC IIM4 standard.
