Classes

class  Exiv2::BasicIo
 An interface for simple binary IO. More...
 
class  Exiv2::IoCloser
 Utility class that closes a BasicIo instance upon destruction. Meant to be used as a stack variable in functions that need to ensure BasicIo instances get closed. Useful when functions return errors from many locations. More...
 
class  Exiv2::FileIo
 Provides binary file IO by implementing the BasicIo interface. More...
 
class  Exiv2::MemIo
 Provides binary IO on blocks of memory by implementing the BasicIo interface. A copy-on-write implementation ensures that the data passed in is only copied when necessary, i.e., as soon as data is written to the MemIo. The original data is only used for reading. If writes are performed, the changed data can be retrieved using the read methods (since the data used in construction is never modified). More...
 

Namespaces

 Exiv2
 Provides classes and functions to encode and decode Exif and Iptc data. The libexiv2 API consists of the objects of this namespace.
 

Functions

DataBuf Exiv2::readFile (const std::string &path)
 Read file path into a DataBuf, which is returned. More...
 
long Exiv2::writeFile (const DataBuf &buf, const std::string &path)
 Write DataBuf buf to file path. More...
