Plan 9 - man page for remap (plan9 section 9)

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 colormap, come  closest  to  reproducing  the
       input image.  The output picture includes a copy of the colormap.

SOURCE
       /sys/src/fb/cmap.c
       /sys/src/fb/remap.c

SEE ALSO
       picfile(9.6)

BUGS
       Both commands work only if the input image contains rgb channels.
