mediaLib Library Functions         mlibImageColorRGB2Mono(3MLIB)



NAME
     mlibImageColorRGB2Mono - RGB to monochrome conversion

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

     mlibstatus mlibImageColorRGB2Mono(mlibimage *dst, const mlibimage *src,
          const mlibd64 *weight);


DESCRIPTION
     The mlibImageColorRGB2Mono() function performs a conversion
     from  a  red/green/blue to a monochromatic image. The source
     image must be a three-channel image. The  destination  image
     must be a single-channel image.


     It uses the following equation:

       dst[x][y][0] = weight[0]*src[x][y][0] ]
                      weight[1]*src[x][y][1] ]
                      weight[2]*src[x][y][2]


PARAMETERS
     The function takes the following arguments:

     dst       Pointer to destination image.


     src       Pointer to source image.


     weight    Array of three blending coefficients. It is recom-
               mended  that  these  sum  to  1.0,  but  it is not
               required.


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