ifdName()

const char * Exiv2::ExifTags::ifdName ( const std::string & groupName )

static

sectionName()

const char * Exiv2::ExifTags::sectionName ( const ExifKey & key )

static

Return the name of the section for an Exif key.

tagList()

const TagInfo * Exiv2::ExifTags::tagList ( const std::string & groupName )

static

Return read-only list of built-in groupName tags.
