       pnmmargin - add borders to a PNM image

pnmpad does essentially the same thing, but gives you more control over the individual margins  and  does
       only black and white margins.

       To  remove  a  border  of  a  specified size from an image, usepamcut.  pnmcrop also removes borders, but
       determines by itself what is border and what is subject.

       If you want to make the image a certain required size, adding borders or cropping  as  necessary,  pamcut
       may be what you want.

       In addition to the options common to all programs based on libnetpbm (most notably  -plain,  see   Common
       Options ), pnmmargin recognizes the following command line options:

       You  can  specify  the  border color with the -white, -black, and -color options.  If you don't specify a
       color, the program makes a guess.

       The value of -color is like the argument of the pnm_parsecolor() library routine .

       The -plain common option was implemented beginning with Netpbm version 10.40 (September 2007).

       The -quiet common option is not implemented.
