     PIC2PS(9.1)                                           PIC2PS(9.1)

     NAME
          pic2ps, pic2gif - convert picture files to other formats

     SYNOPSIS
          fb/pic2ps [ -c ] [ -h height ] [ input ]

          fb/pic2gif [ -i ] [ -l ] [ -b depth ] [ input ]

     DESCRIPTION
          Pic2ps converts its input image (default standard input)
          into encapsulated PostScript, writing the result to standard
          output.  If the input image is full-color, its luminance is
          computed first, except under option -c, which produces out-
          put suitable for a color PostScript printer.  Option -h sets
          the output image height in inches.  The default height is
          3", to match the default height of the .BP macro in troff
          -mpictures.

          Pic2gif converts its input image (default standard input)
          into a Compuserv GIF format file, writing the result to
          standard output.  It converts only the first channel of the
          input image, which may yield wrong results - use the -l flag
          or quantize(9.1) or some other dithering filter to reduce
          color images to a single channel.  Option -i produces an
          interlaced output file.  Option -b sets the number of bits
          per pixel in the output file.  The default is 8, which is
          the maximum.  Option -l makes pic2gif compute the NTSC lumi-
          nance of its input.  If pic2gif's input contains no color
          map, it assumes that it is a 256 grey shade monochrome
          image.
