mediaLib Library Functions         mlib_ImageBlend1_Fp_Inp(3MLIB)



NAME
     mlib_ImageBlend1_Fp_Inp - blend with an alpha image

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

     mlib_status mlib_ImageBlend1_Fp_Inp(mlib_image *src1dst,
          const mlib_image *src2, const mlib_image *alpha);


DESCRIPTION
     The mlib_ImageBlend1_Fp_Inp()  function  blends  two  images
     together, in place, on a pixel-by-pixel basis using an alpha
     image, when alpha is also on a pixel basis. The alpha  image
     can  be  a  single-channel  image or have the same number of
     channels as the source and destination images.


     It uses the following equation when the  alpha  image  is  a
     single-channel image:

       src1dst[x][y][i] = alpha[x][y][0]*src1dst[x][y][i] +
                          (1 - alpha[x][y][0])*src2[x][y][i]



     It uses the following equation when the alpha image has  the
     same  number  of  channels  as  the  source  and destination
     images:

       src1dst[x][y][i] = alpha[x][y][i]*src1dst[x][y][i] +
                          (1 - alpha[x][y][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      Alpha image used to control blending. The  pixels
                in  this image should have values in the range of
                [0.0,1.0].


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