PGMTOPS

NAME

      pgmtops - convert a portable graymap into Encapsulated PostScript

SYNOPSIS

      pgmtops [-rle] [-scale <x>] [<pgmfile>]

DESCRIPTION

      Reads a portable graymap as input.  Produces Encapsulated PostScript
      as output.
      The -scale flag controls the scale of the result.  The default scale
      is 1, which results in one pgm pixel producing a 3x3 square of
      PostScript pixels.  On a 300 dpi printer such as the Apple
      LaserWriter, this makes the output look about the same size as the
      input would if it was displayed on a typical 72 dpi screen.  To get
      one pgm pixel per LaserWriter pixel, use "-s 0.333333".
      The -rle flag specifies run-length compression.  This may save time if
      the host-to-printer link is slow; but normally the printer's
      processing time dominates, so -rle makes things slower.
      All flags can be abbreviated to their shortest unique prefix.
      Note that there is no pstopgm tool - this transformation is one-way,
      because a pstopgm tool would be a full-fledged PostScript interpreter,
      which is beyond the scope of this package.  However, see the psidtopgm
      tool.

      the EPS image did load, it also locked up his machine.
