REMAP(9.1)																REMAP(9.1)

NAME
       cmap, remap - map colors

SYNOPSIS
       fb/cmap colormap [ input ]

       fb/remap colormap [ input ]

DESCRIPTION
       Cmap  looks  up	the  rgb  channels of the input picture file (default standard input), in the colormap, writing the resulting rgb image to
       standard output.  That is, cmap writes on its output the result of applying the colormap to the pixels of the input image.

       Remap is approximately the inverse of cmap.  Pixel values in the input image are replaced by those that, when mapped through the input col-
       ormap, come closest to reproducing the input image.  The output picture includes a copy of the colormap.

BUGS
