NAME
       pamwipeout - replace detail with smooth gradient from one edge to the other

SYNOPSIS
       pamwipeout {-lr | -tb} [filename]

       Minimum	unique abbreviation of options is acceptable.  You may use double hyphens instead of single hyphen to denote
       options.

DESCRIPTION
       This program is part of Netpbm(1).

       pamwipeout replaces every row or column (as directed) with a smooth gradient between the pixel values at	 each  edge.
       You can use it in combination with pamcut and pnmpaste / pamcomp to remove unwanted parts of a larger image.

       In  top-bottom  mode, the program reads the whole image into memory before it can start processing.  In left-right it
       will read the image a row at the time, process that row and write it to the output file.	 Therefore, in case of	very
       large  images,  it may be better to use instead of "pamwipeout -tb" a pipe of "pamflip -cw | pamwipeout -lr | pamflip
       -ccw".

PARAMETERS
       Filename is the name of the input file. If you don't specify this, pamwipeout reads the image from Standard Input.

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

       -tb | -lr

	      This  option  chooses  between  a	 vertical and a horizontal gradient.  You must specify one of these, but not
	      both.

SEE ALSO
       pam(1) and pamflip(1), pamcut(1), pamcomp(1), pnmpaste(1).

HISTORY
       pamwipeout was new in Netpbm 10.54 (March 2011).

       A predecessor program (not part of Netpbm) was called pnmblend.

AUTHORS
       Willem van Schaik wrote this program in January 2011 and contributed it to Netpbm.
