Detailed Description

converts a "long" image to a "byte" image

Usage: long2byte in.pgm [mode] [n] out.pgm

Description:

Depending on the value given for the (optional) parameter mode:

mode = 0 (default) : for all x, out[x] = min(255, in[x]).
mode = 1 : for all x, out[x] = in[x] modulo 256.
mode = 2 : scales values in the range 0-255.
mode = 3 : sorts the values by decreasing number of occurence in the image. Replaces the values by their order. Only the n (default 255) first values are kept. Useful for label images.
mode = 4 : truncation of the square root in the range 0-255.
mode = 5 : truncation of the log in the range 0-255.
