typedef std::ostream &(* Exiv2::PrintFct )(std::ostream &, const Value &)
 Type for a function pointer for functions interpreting the tag value.

Enumerations

enum  Exiv2::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

bool Exiv2::isExifIfd (IfdId ifdId)
 Return true if ifdId is an Exif Ifd Id, i.e., one of ifd0Id, exifIfdId, gpsIfdId, iopIfdId or ifd1Id, else false. This is used to differentiate between standard Exif Ifds and Ifds associated with the makernote.
std::ostream & Exiv2::operator<< (std::ostream &os, const TagInfo &ti)
