           All  options  can  be abbreviated to their shortest unique prefix.  You
           may use two hyphens instead of one.  You may separate  an  option  name
           and its value with white space instead of an equals sign.


           Reads  a  Netpbm  image  as input.  Produces Encapsulated PostScript as
           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.
           If  you  specify  no  output  dimensioning options, the output image is
           dimensioned as if you had specified  -scale=1.0,  which  means  aproxi-
           mately  72  pixels  of  the input image generate one inch of output (if
           that fits the page).
           Use  -imagewidth,  -imageheight,  -equalpixels,  -width,  -height,  and
           -scale to adjust that.


                  -imageheight  Tells  how wide and high you want the image on the
                  page, in inches.  The aspect ratio of the image is preserved, so
                  if  you specify both of these, the image on the page will be the
                  largest image that will fit within the box of those  dimensions.
                  If  these  dimensions  are  greater  than the page size, you get
                  Postscript output that runs off the page.
                  You  cannot  use  imagewidth  or  imageheight  with  -scale   or
                  This  option  causes the output image to have the same number of
                  pixels as the input image.  So if the output device is  600  dpi
                  and  your image is 3000 pixels wide, the output image would be 5
                  inches wide.
                  You cannot use -equalpixels with -imagewidth,  -imageheight,  or
                  either  by  the  -width  and -height options or the default page
                  size of 8.5 inches by 11 inches),  pnmtops  ignores  the  -scale
                  option,  issues  a  warning,  and scales the image to fit on the
           -dpi   This option specifies the dots per inch of your  output  device.
                  The default is 300 dpi.  In theory PostScript is device-indepen-
                  dent 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.
                  Also this option is crucial to the working  of  the  equalpixels
                  -height  These  options  specify  the  dimensions of the page on
                  which the output is to be printed.  This can affect the size  of
                  the output image.
                  The  page  size  has  no  effect,  however, when you specify the
                  -imagewidth, -imageheight, or -equalpixels options.
                  These options may also affect positioning of the  image  on  the
                  page and even the paper selected (or cut) by the printer/plotter
                  when the output is printed.  See the -nosetpage option.
                  The default is 8.5 inches by 11 inches.
           -turn  -noturn These options control whether the image gets  turned  90
                  degrees.  Normally, if an image fits the page better when turned
                  (e.g. the image is wider than it is tall, but the page is taller
                  than it is wide), 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.
           -rle   -runlength These identical options specify  run-length  compres-
                  sion.   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.
                  By  default,  pnmtops centers the image on the output page.  You
                  can cause pnmtops to instead put the  image  against  the  upper
                  left corner of the page with the -nocenter option.  This is use-
                  ful for programs which can include PostScript files,  but  can't
                  cope  with  pictures  which are not positioned in the upper left
                  Before  release 10.0 the default was to generate the "setpagede-
                  vice" directive, and there is the switch -nosetpage  to  supress
                  it, but that's actually a no-op now.
