Individual icons from a Fontographer font database (.fog files) can be exported as TrueType Fonts (.ttf files) either with the Fontographer program itself, or with some other dedicated font editor and conversion programs, for example FogLamp. A fog to ttf conversion will be typically used to export individual symbols and save them as pictures.
