mediaLib Library Functions       mlib_ImageScalarBlend_Inp(3MLIB)



NAME
     mlib_ImageScalarBlend_Inp - image blending with  scalar,  in
     place

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

     mlib_status mlib_ImageScalarBlend_Inp(mlib_image *src1dst,
          const mlib_image *src2, const mlib_s32 *alpha);


DESCRIPTION
     The mlib_ImageScalarBlend_Inp() function  blends  the  first
     and second source images by adding each of their scaled pix-
     els 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
                *  2**(-31)). alpha[i] contains the blending fac-
                tor for channel i.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
