This graph shows which files directly or indirectly include this file:

Namespaces
namespace	Exiv2
Classes
struct	Exiv2::IfdInfo
	Contains information pertaining to one IFD. More...
struct	Exiv2::IfdInfo::Item
	Search key to find an IfdInfo by its IFD item. More...
struct	Exiv2::SectionInfo
	Contains information pertaining to one section. More...
struct	Exiv2::TagInfo
	Tag information. More...
struct	Exiv2::TagDetails
	Helper structure for lookup tables for translations of numeric tag values to human readable labels. More...
struct	Exiv2::TagDetailsBitmask
	Helper structure for lookup tables for translations of bitmask values to human readable labels. More...
class	Exiv2::ExifTags
	Container for Exif tag information. Implemented as a static class. More...
class	Exiv2::ExifKey
	Concrete keys for Exif metadata. More...
Defines
#define	EXV_PRINT_TAG(array)   printTag<EXV_COUNTOF(array), array>
	Shortcut for the printTag template which requires typing the array name only once.
#define	EXV_PRINT_TAG_BITMASK(array)   printTagBitmask<EXV_COUNTOF(array), array>
	Shortcut for the printTagBitmask template which requires typing the array name only once.
Typedefs
typedef std::ostream &(*	PrintFct )(std::ostream &, const Value &)
	Type for a function pointer for functions interpreting the tag value.
typedef const TagInfo *(*	TagListFct )()
	A function returning a tag list.
Enumerations
enum	SectionId {   sectionIdNotSet, imgStruct, recOffset, imgCharacter,   otherTags, exifFormat, exifVersion, imgConfig,   userInfo, relatedFile, dateTime, captureCond,   gpsTags, iopTags, makerTags, lastSectionId }
	Section identifiers to logically group tags. A section consists of nothing more than a name, based on the Exif standard.
Functions
template<int N, const TagDetails & array>
std::ostream &	printTag (std::ostream &os, const Value &value)
	Generic print function to translate a long value to a description by looking up a reference table.
template<int N, const TagDetailsBitmask & array>
std::ostream &	printTagBitmask (std::ostream &os, const Value &value)
	Generic print function to translate a long value to a description by looking up bitmasks in a reference table.
