NAME

   pnmcat - concatenate Netpbm images

SYNOPSIS

   pnmcat     {-leftright     |	  -lr	|   -topbottom	 |   -tb}
[-white|-black]
   [-jtop|-jbottom|-jcenter] pnmfile ...

   Minimum unique abbreviation of option is acceptable.	 You  may
use double
   hypens instead of single hyphen to denote options. You may use
white space
   in place of the equals sign to separate an  option  name  from
its value.

DESCRIPTION

   This program is part of Netpbm.

   pnmcat  reads  one  or  more PNM images as input, concatenates
them either left
   to right or top to bottom, and produces a single PNM image  as
output.

   To  do the reverse, you might use pamdice to split an image up
into smaller
   ones of equal size or pamcut to chop off part of an	image  or
extract part of
   an image.

   pnmtile  concatenates a single input image to itself repeated-
ly.

OPTIONS

   If  the  PNM	 images are not all the same height  (left-right)
or width
   (top-bottom),  the  smaller ones have to be justified with the
largest. By
   default, pnmcat centers them, but you can  specify  justifica-
tion to one side
   or  the  other  with	 one of the -jxxx options. So, -topbottom
-jleft would
   stack the PNMs on top of each other, flush with the left edge.

   The	-white	and  -black  options specify what color to use to
fill in the extra
   space when doing this justification. If neither is  specified,
pnmcat chooses
   whichever seems to be right for the images.
