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 spec-
       ified, it will not be turned no matter what its shape.

       The -rle or -runlength flag specifies run-length  compres-
       sion.   This  may save time if the host-to-printer link is
       slow; but normally the  printer's  processing  time  domi-
       nates, 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 pre-
       fix.
