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)

       The pamwipeout utility takes a Neptbm image as input and the uses two  opposite	edges  of
       the  image to wipe out anything in between.  You can use it in combination with pamcut and
       pnmpaste / pamcomp to remove unwanted parts of a larger image.  The program  replaces  the
       pixels in between the two edges with a gradient from one edge to the other.

       In top-bottom mode, the program reads the whole image into memory before it can start pro-
       cessing.  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".

       In his blog at

       www.i-am.ws <http://www.i-am.ws/entry/pnmblend_disappearing_act> , the author wrote  about
       a  predecessor  of  "pamwipeout"  at the time named "pnmblend". It shows a good example of
       what can be accomplished with this utility.

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

OPTIONS
       <dl compact="compact">

       -tb | -lr

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