NAME
      pnmtops - convert portable anymap to PostScript

SYNOPSIS
      pnmtops [-scale s] [-turn|-noturn] [-rle|-runlength] [-dpi n] [-width n]
      [-height n] [pnmfile]

DESCRIPTION
      Reads a portable anymap as input.  Produces Encapsulated PostScript as
      output.

      If the input file is in color (PPM), a color PostScript file gets
      written.  Some PostScript interpreters can't handle color PostScript.  If
      you have one of these you will need to run your image through ppmtopgm
      first.

      Note that there is no pstopnm tool - this transformation is one-way,
      because a pstopnm tool would be a full-fledged PostScript interpreter,
      which is beyond the scope of this package.  However, see the psidtopgm
      tool, which can read grayscale non-runlength PostScript image data.
      Also, if you're willing to install the fairly large GhostScript package,
      it comes with a pstoppm script.

OPTIONS
      The -scale flag controls the scale of the result.  The default scale is
      1, which on a 300 dpi printer such as the Apple LaserWriter 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 PNM pixel per 300 dpi printer pixel,
      use "-scale 0.25".

      The -turn and -noturn flags control whether the image gets turned 90
      degrees.  Normally, if an image is wider than it is tall, it gets turned
      automatically to better fit the page.  If the -turn flag is specified, it
      will be turned no matter what its shape; and if the -noturn flag is
      specified, it will not be turned no matter what its shape.

      The -rle or -runlength 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.

      The -dpi flag lets you specify the dots per inch of your output device.
      The default is 300 dpi.  In theory PostScript is device-independent and
      you don't have to worry about this, but in practice its raster rendering
      can have unsightly bands if the device pixels and the image pixels aren't
      in sync.

      The -width and -height flags let you specify the size of the page.  The
      default is 8.5 inches by 11 inches.

      All flags can be abbreviated to their shortest unique prefix.
