cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstDiv_Inp(mlib_image *srcdst, const mlib_d64 *c);
The mlib_ImageConstDiv_Inp() function divides each pixel in an image by a constant value on a pixel-by-pixel basis, in place.
It uses the following equation:
srcdst[x][y][i] = c[i] / srcdst[x][y][i]
In the case of srcdst[x][y][i] = 0,
srcdst[x][y][i] = 0 if c[i] = 0 srcdst[x][y][i] = DATA_TYPE_MAX if c[i] > 0 srcdst[x][y][i] = DATA_TYPE_MIN if c[i] < 0
where DATA_TYPE is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT, respectively.
The function takes the following arguments:
Pointer to source and destination image.
Constant into which each pixel is divided. c[i] contains the constant for channel i.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
