DESCRIPTION

17       The  mlib_ImageConstSub() function subtracts an image pixel from a con‐
18       stant on a pixel-by-pixel basis.
19
20
21       It uses the following equation:
22
23         dst[x][y][i] = c[i] - src[x][y][i]
24
25

PARAMETERS

27       The function takes the following arguments:
28
29       dst    Pointer to destination image.
30
31
32       src    Pointer to source image.
33
34
35       c      Array of constants from which each pixel is subtracted by  chan‐
36              nel. c[i] contains the constant for channel i.
