SMUSH(1)		    General Commands Manual		      SMUSH(1)

NAME
       smush - defocus an RLE image.

SYNOPSIS
       smush [ -m maskfile ] [ -n ] [ -o outfile ] [ levels ] [	infile ]

DESCRIPTION
       Smush  convolves	an image with a	5x5 Gaussian mask, blurring the	image.
       One may also provide a mask in a	text file.  The	file must  contain  an
       integer	to  specify the	size of	the square mask, followed by size*size
       floats.	The mask will be normalized (forced to sum to 1.0) unless  the
       -n flag is given.

       The  resulting  image  is the same size as the input image, no sub-sam-
       pling takes place.  The levels option, which defaults to	one, signifies
       the  number  of times which the image will be blurred.  Each successive
       blurring	is done	with a more spread out mask, so	a smush	of level 2  is
       blurrier	 than  piping  two level one smush calls.  If no input file is
       specified, smush	reads from stdin.  If no output	file is	specified with
       -o it writes the	result to stdout.

BUGS
       Smush  should probably automatically generate different sized gaussians
       and other common	filters.
