NAME
applylut - apply a text gray-level look-up table to a byte or short
formatted HIPS image.
SYNOPSIS
applylut
lut_file < inseq > outseq
DESCRIPTION
applylut
reads a text file containing a new gray-level look-up table and
applies this look-up table to a sequence of images. The format of
the look-up table is all integers; the first number indicates the
size of the look-up table (normally 256 for byte images and 65536
for short images, however any size is possible), followed by a
list of new values. The order in the file determines the value to
be mapped from. For example, 0 will be mapped the the the 1st
value in the file, 1 to the 2nd, 255 to the 256th, 60000 to
the 60001th, etc.
If your look-up table contains less entries than the number of gray levels
in your file, remaining gray-levels will be mapped to 0.
