mediaLib Library Functions    mlibImageScalarBlendFpInp(3MLIB)



NAME
     mlibImageScalarBlendFpInp - image blending with scalar

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

     mlibstatus mlibImageScalarBlendFpInp(mlibimage *src1dst,
          const mlibimage *src2, const mlibd64 *alpha);


DESCRIPTION
     The mlibImageScalarBlendFpInp() function blends the first
     and  second  floating-point  source images by adding each of
     their scaled pixels in place.  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:

       src1dst[x][y][i] = a[i]*src1dst[x][y][i] ]
                          (1 - a[i])*src2[x][y][i]


PARAMETERS
     The function takes the following arguments:

     src1dst    Pointer to first source and destination 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.
