NAME

       pnmpad - add borders to portable anymap

SYNOPSIS

       pnmpad [-verbose] [-white|-black]
       [[[-width=width [-halign=ratio]] |
          [-left=leftpad] [-right=rightpad]]]
       [[[-height=height [-valign=ratio]] |
          [-top=toppad] [-bottom=botpad]]]
       [pnmfile]

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

DESCRIPTION

       Reads  a  PNM  image as input. Outputs a PNM image that is the input image plus black or white borders of
       the sizes specified.

       If you just need to convert an image to a certain size regardless of the original dimensions, pnmcut with
       the -pad option may be a better choice.

OPTIONS

       -verbose
              Verbose output.

       -white
       -black (default)
              Set pad color.

       -left leftpad
       -right rightpad
       -top toppad
       -bottom bottompad
              Specify amount of padding in pixels.

       -width width
              Set desired width of image. Overrides -left and -right if specified. If width  is  less  than  the
              actual image width, it is ignored. Use pnmcut(1) to cut off parts of images.

       -height height
              Set  desired  height of image. Overrides -top and -bottom if specified. If height is less than the
              actual image height, it is ignored. Use pnmcut(1) to cut off parts of images.

       -halign ratio
              A real number between 0 and 1. Used in conjunction with -width, sets the alignment  ratio  between
              left padding and right padding.

              Useful values:

              0.0    - left aligned;

              0.5    - center aligned (default);

              1.0    - right aligned.

       -valign ratio
              A  real number between 0 and 1. Used in conjunction with -height, sets the alignment ratio between
              bottom padding and top padding.

              Useful values:

              0.0    - bottom aligned;

              0.5    - center aligned (default);

              1.0    - top aligned.

HISTORY

       Before February 2002,
              pnmpad had a different option syntax which was less expressive and not  like  conventional  Netpbm
              programs.   That  syntax  is  still  understood  by  pnmpad  for  backward  compatibility, but not
              documented or supported for future use.
