       pnmcat - concatenate Netpbm images



       {-leftright | -lr | -topbottom | -tb}



       pnmfile ...

       Minimum  unique abbreviation of option is acceptable.  You may use dou-
       ble hyphens 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.


       This program is part of Netpbm(1).

       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 out-

       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 repeatedly.


       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  justification  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

       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.
