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.
