ustring extensionsUri ( const size_t  index ) const Get an E57 extension URI declared in an ImageFile by index. Parameters: [in] index The index of the URI to get, starting at 0. The order that the URIs are stored is not necessarily the same as the order they were created. However the URI order will correspond to the prefix order. The default E57 namespace is not counted as an extension. Precondition: This ImageFile must be open (i.e. isOpen()). 0 <= index < extensionsCount() Postcondition: No visible state is modified. Returns: The E57 extension URI at the given index. Exceptions: E57_ERROR_BAD_API_ARGUMENT E57_ERROR_IMAGEFILE_NOT_OPEN E57_ERROR_INTERNAL All objects in undocumented state See also: Extensions.cpp example, ImageFile::extensionsCount, ImageFile::extensionsPrefix
