pnmtops(1)

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),  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 -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.

       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.

       With the -nocenter flag, the output is not centered on the
       page,  i.e.  it  appears in the upper left corner. This is
       useful for programs which can  include  PostScript  files,
       but  can't  cope with pictures which are not positioned in
       the upper left corner. The default  is  -center  i.e.  the
       image is centered on the page.

       All flags can be abbreviated to their shortest unique pre-
       fix.
