  36 %  Display is a machine architecture independent image processing
  37 %  and display program.  It can display any image in the MIFF format on
  38 %  any workstation display running X.  Display first determines the
  39 %  hardware capabilities of the workstation.  If the number of unique
  40 %  colors in the image is less than or equal to the number the workstation
  41 %  can support, the image is displayed in an X window.  Otherwise the
  42 %  number of colors in the image is first reduced to match the color
  43 %  resolution of the workstation before it is displayed.
  44 %
  45 %  This means that a continuous-tone 24 bits-per-pixel image can display on a
  46 %  8 bit pseudo-color device or monochrome device.  In most instances the
  47 %  reduced color image closely resembles the original.  Alternatively, a
  48 %  monochrome or pseudo-color image can display on a continuous-tone 24
  49 %  bits-per-pixel device.
