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.
