mediaLib Library Functions       mlib_ImageColorTrue2Index(3MLIB)



NAME
     mlib_ImageColorTrue2Index -  true  color  to  indexed  color
     using nearest matched LUT entries

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

     mlib_status mlib_ImageColorTrue2Index(mlib_image *dst,
          const mlib_image *src, const void *colormap);


DESCRIPTION
     The mlib_ImageColorTrue2Index()  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 MLIB_BYTE or MLIB_SHORT image
     with three or four  channels.  The  destination  must  be  a
     single-channel MLIB_BYTE or MLIB_SHORT image.


     The last parameter, colormap, is an internal data  structure
     (which includes the lookup table) for inverse color mapping.
     Create it  by  calling  the  mlib_ImageColorTrue2IndexInit()
     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 MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
