NAME
        pnmtops - convert portable anymap to PostScript
 
SYNOPSIS
        pnmtops  [-scale  s]  [-dpi  n]  [-width  n]  [-height  n]
        [-turn|-noturn]   [-rle|-runlength]    [-center|-nocenter]
        [pnmfile]
 
DESCRIPTION
        Reads  a  portable anymap as input.  Produces Encapsulated
        PostScript as output.
 
        If the input file is in color (PPM), pnmtops  generates  a
        color PostScript file.  Some PostScript interpreters can't
        handle color PostScript.  If you have  one  of  these  you
        will need to run your image through ppmtopgm first.
 
OPTIONS
        The  -scale  option 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 -dpi option 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 options let you specify the size of
        the page.  The default is 8.5 inches by 11 inches.
 
        The -turn and -noturn options 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 you specify the -turn option, pnmtops
        turns the image no matter what its shape; If  you  specify
        -noturn,  pnmtops  does  not  turn  it  no matter what its
        shape.
 
        The -rle or -runlength option  specifies  run-length  com­
        pression.   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.
 
        By  default, pnmtops centers the image on the output page.
        You can specify this explicitly with the  -center  option,
        or  cause  pnmtops  to  instead  put the image against the
        upper left corner of the page with the  -nocenter  option.
        The  latter  is  useful  for  programs  which  can include
        PostScript files, but can't cope with pictures  which  are
        not positioned in the upper left corner.
 
        All  options  can  be abbreviated to their shortest unique
        prefix.
