mediaLib Library Functions       mlibImageColorTrue2Index(3MLIB)



NAME
     mlibImageColorTrue2Index -  true  color  to  indexed  color
     using nearest matched LUT entries

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibImageColorTrue2Index(mlibimage *dst,
          const mlibimage *src, const void *colormap);


DESCRIPTION
     The mlibImageColorTrue2Index()  function  converts  a  true
     color image to a pseudo color image with the method of find-
     ing the nearest matched lookup table entry for  each  pixel.
     The  source  image  can  be an MLIBYTE or MLIBSHORT image
     with three or four  channels.  The  destination  must  be  a
     single-channel MLIBYTE or MLIBSHORT image.


     The last parameter, colormap, is an internal data  structure
     (which includes the lookup table) for inverse color mapping.
     Create it  by  calling  the  mlibImageColorTrue2IndexInit()
     function.

PARAMETERS
     The function takes the following arguments:

     dst         Pointer to destination or destination image.


     src         Pointer to source or source image.


     colormap    Internal data structure for inverse  color  map-
                 ping.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
