mediaLib Library Functions        mlibImageScalarBlendFp(3MLIB)



NAME
     mlibImageScalarBlendFp - image blending with scalar

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

     mlibstatus mlibImageScalarBlendFp(mlibimage *dst,
          const mlibimage *src1, const mlibimage *src2, const mlibd64 *alpha);


DESCRIPTION
     The mlibImageScalarBlendFp() function blends the first and
     second  floating-point source images by adding each of their
     scaled pixels. The first  source  image  is  scaled  by  the
     scalar  a,  and the second source image is inverse scaled by
     (1 - a).


     It uses the following equation:

       dst[x][y][i] = a[i]*src1[x][y][i] ] (1 - a[i])*src2[x][y][i]


PARAMETERS
     The function takes the following arguments:

     dst      Pointer to destination image.


     src1     Pointer to first source image.


     src2     Pointer to second source image.


     alpha    Scalar blending factor. The a  value  equals  alpha
              which  should  be in the [0.0, 1.0] range. alpha[i]
              contains the blending factor for channel i.


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