    mlib_s32 shift);

 

DESCRIPTION

The mlib_ImageMulShift_Inp() function multiplies the pixel values of the two source images in place. It scales the result by a right shift and writes the result to the destination image on a pixel-by-pixel basis.

It uses the following equation:

src1dst[x][y][i] = src1dst[x][y][i] * src2[x][y][i] * 2**(-shift)

 

PARAMETERS

The function takes the following arguments:

src1dst

Pointer to source and destination image.

src2

Pointer to second source image.

shift

Right shifting factor. 0 ≤ shift ≤ 31.

 

RETURN VALUES

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