outline font
vector font

    (Or "vector font") A font defined as a set of lines
   and curves as opposed to a bitmap font.  An outline font
   (e.g. PostScript, TrueType, RISC OS) can be scaled to any
   size and otherwise transformed more easily than a bitmap font,
   and with more attractive results, though this requires a lot
   of numerical processing.  The result of transforming a
   character in an outline font in a particular way is often
   saved as a bitmap in a font cache to avoid repeating the
   calculations if that character is to be drawn again.
