NAME
bin_mask - apply a bitmask to each pixel of an image
SYNOPSIS
bin_mask
[-m mask] < inseq > outseq
DESCRIPTION
Bin_mask
sets the bits of each pixel in the input image
by ANDing them with the input mask. The input sequence must
be byte or short format. The output sequence is the same as
the input.
The input mask is specified with the option m. The -m option
calls for a string of 1's and 0's. If -m is not set then the
default is '100,' setting the lower two bits of each pixel in
the image to zero.
Setting high order bits to 0 (e.g. -m 00111111) is almost sure
to require renormalizing the image with, for example, scale_gray
for it to be visible on a screen.
OPTIONS
-m %s string of 1's and 0's defining the mask (default = '100')
