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-sampling 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
If no input file is specified,
smush reads from stdin. If no output file is specified with
-o it writes the result to stdout.
