17 The mlib_ImageMulShift_Inp() function multiplies the pixel values of
18 the two source images in place. It scales the result by a right shift
19 and writes the result to the destination image on a pixel-by-pixel
20 basis.
21
22
23 It uses the following equation:
24
25 src1dst[x][y][i] = src1dst[x][y][i] * src2[x][y][i] * 2**(-shift)
26
27
29 The function takes the following arguments:
30
31 src1dst Pointer to source and destination image.
32
33
34 src2 Pointer to second source image.
35
36
37 shift Right shifting factor. 0 ≤ shift ≤ 31.

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