          mugs - convert gray-scale pictures into icons

          mugs picture ...

          Mugs is an interactive program for converting gray-scale
          images (usually scanned-in photographs) into the 48×48 icons
          used by vismon(9.1) and other programs.  After digesting the
          first picture file, mugs will display an approximation to
          the original picture, a vertical slider-bar and a 48×48
          icon.  Hitting button 1 in the slider-bar and sliding verti-
          cally adjusts the low and high points of values of the 48×48
          image.  Button 2 adjusts the low and high values simultane-
          ously (i.e. it changes the brightness without disturbing the
          contrast.)  Button 3 presents a menu with entries:

               Select a square window in the original picture using
               button 3.  Touch down at the center of the square and
               slide around to adjust its size.

          save Type in the name of a file in which to save the cur-
               rently displayed 48×48 icon.

          next Move on to the next picture mentioned on the command

          exit Confirm with button 3.

          The format of mugs's input files is largely undocumented.
          Among other things, it will accept files containing an array
          of one-byte pixels of dimensions 480x512, 486x512, 488x512,
          496x512, 497x512, 512x512, 2047x2048 or 2048x2048.
