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::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...

template<typename T, typename K, int N>
const T* find T &  src[N],
const K &  key
 

Find an element that matches key in the array src.

Designed to be used with lookup tables as shown in the example below. Requires a Key structure (ideally in the array) and a comparison operator to compare a key with an array element. The size of the array is determined automagically. Thanks to Stephan Broennimann for this nifty implementation.

      struct Bar {
          int i;
          int k;
          const char* data;

          struct Key;
          bool operator==(const Bar::Key& rhs) const;
      };

      struct Bar::Key {
          Key(int a, int b) : i(a), k(b) {}
          int i;
          int k;
      };

      bool Bar::operator==(const Bar::Key& key) const // definition
      {
          return i == key.i && k == key.k;
      }

      const Bar bars[] = {
          { 1, 1, "bar data 1" },
          { 1, 2, "bar data 2" },
          { 1, 3, "bar data 3" }
      };

      int main ( void ) {
          const Bar* bar = find(bars, Bar::Key(1, 3));
          if (bar) std::cout << bar->data << "\n";
          else std::cout << "Key not found.\n";
          return 0;
      }

Rational floatToRationalCast float  f  ) 
 

Very simple conversion of a float to a Rational.

Test it with the values that you expect and check the implementation to see if this is really what you want!

template<typename IntType>
IntType gcd IntType  n,
IntType  m
 

Return the greatest common denominator of n and m. (Implementation from Boost rational.hpp).

Note:
We use n and m as temporaries in this function, so there is no value in using const IntType& as we would only need to make a copy anyway...

template<typename T>
Rational Exiv2::getValue const byte buf,
ByteOrder  byteOrder
[inline]
 

Read a value of type T from the data buffer.

We need this template function for the ValueType template classes. There are only specializations of this function available; no default implementation is provided.

Parameters:
buf Pointer to the data buffer to read from.
byteOrder Applicable byte order (little or big endian).
Returns:
A value of type T.

float parseFloat const std::string &  s,
bool &  ok
 

Return a float set to the value represented by s.

Besides strings that represent float values, the function also handles long, Rational and boolean (see also: stringTo(const std::string& s, bool& ok)).

Parameters:
s String to parse
ok Output variable indicating the success of the operation.
Returns:
Returns the float value represented by s and sets ok to true if the conversion was successful or false if not.

long parseLong const std::string &  s,
bool &  ok
 

Return a long set to the value represented by s.

Besides strings that represent long values, the function also handles float, Rational and boolean (see also: stringTo(const std::string& s, bool& ok)).

Parameters:
s String to parse
ok Output variable indicating the success of the operation.
Returns:
Returns the long value represented by s and sets ok to true if the conversion was successful or false if not.

Rational parseRational const std::string &  s,
bool &  ok
 

Return a Rational set to the value represented by s.

Besides strings that represent Rational values, the function also handles long, float and boolean (see also: stringTo(const std::string& s, bool& ok)). Uses floatToRationalCast(float f) if the string can be parsed into a float.

Parameters:
s String to parse
ok Output variable indicating the success of the operation.
Returns:
Returns the Rational value represented by s and sets ok to true if the conversion was successful or false if not.

template<typename T>
Exifdatum & Exiv2::setValue Exifdatum &  exifDatum,
const T &  value
 

Set the value of exifDatum to value. If the object already has a value, it is replaced. Otherwise a new ValueType<T> value is created and set to value.

This is a helper function, called from Exifdatum members. It is meant to be used with T = (u)int16_t, (u)int32_t or (U)Rational. Do not use directly.

template<typename T>
T stringTo const std::string &  s,
bool &  ok
 

Utility function to convert a string to a value of type T.

The string representation of the value must match that recognized by the input operator for T for this function to succeed.

Parameters:
s String to convert
ok Output variable indicating the success of the operation.
Returns:
Returns the converted value and sets ok to true if the conversion was successful or false if not.

template<>
bool stringTo< bool > const std::string &  s,
bool &  ok
 

Specialization of stringTo(const std::string& s, bool& ok) for bool.

Handles the same string values as the XMP SDK. Converts the string to lowercase and returns true if it is "true", "t" or "1", and false if it is "false", "f" or "0".

bool testVersion int  major,
int  minor,
int  patch
 

Test the version of the available Exiv2 library at runtime. Return true if it is the same as or newer than the passed-in version.

Versions are denoted using a triplet of integers: major.minor.patch .

      // Don't include the <exiv2/version.hpp> file directly, it is included by
      // <exiv2/types.hpp>. Early Exiv2 versions didn't have version.hpp and the macros.

      #include <exiv2/types.hpp>
    
      // Make sure an EXIV2_TEST_VERSION macro exists:
      
      #ifdef EXIV2_VERSION
      # ifndef EXIV2_TEST_VERSION
      # define EXIV2_TEST_VERSION(major,minor,patch) \
          ( EXIV2_VERSION >= EXIV2_MAKE_VERSION(major,minor,patch) )
      # endif
      #else
      # define EXIV2_TEST_VERSION(major,minor,patch) (false)
      #endif
    
      std::cout << "Compiled with Exiv2 version " << EXV_PACKAGE_VERSION << "\n"
                << "Runtime Exiv2 version is    " << Exiv2::version()    << "\n";
    
      // Test the Exiv2 version available at runtime but compile the if-clause only if
      // the compile-time version is at least 0.15. Earlier versions didn't have a
      // testVersion() function:

      #if EXIV2_TEST_VERSION(0,15,0)
      if (Exiv2::testVersion(0,13,0)) {
          std::cout << "Available Exiv2 version is equal to or greater than 0.13\n";
      }
      else {
          std::cout << "Installed Exiv2 version is less than 0.13\n";
      }
      #else
      std::cout << "Compile-time Exiv2 version doesn't have Exiv2::testVersion()\n";
      #endif

template<typename T>
long toData byte buf,
t,
ByteOrder  byteOrder
 

Convert a value of type T to data, write the data to the data buffer.

We need this template function for the ValueType template classes. There are only specializations of this function available; no default implementation is provided.

Parameters:
buf Pointer to the data buffer to write to.
t Value to be converted.
byteOrder Applicable byte order (little or big endian).
Returns:
The number of bytes written to the buffer.
