mlib_ImageDivConstShift - division by a constant, with shifting SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDivConstShift(mlib_image *dst, const mlib_image *src, const mlib_s32 *c, mlib_s32 shift); DESCRIPTION
The mlib_ImageDivConstShift() function divides each pixel in an image by a constant value on a pixel-by-pixel basis. It scales the result by a left shift and writes the result to the destination image on a pixel-by-pixel basis. It uses the following equation: dst[x][y][i] = src[x][y][i] / c[i] * 2**shift In the case of c[i] = 0, dst[x][y][i] = 0 if src[x][y][i] = 0 dst[x][y][i] = DATA_TYPE_MAX if src[x][y][i] > 0 dst[x][y][i] = DATA_TYPE_MIN if src[x][y][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, respec- tively. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. c Constant by which each pixel is divided. c[i] contains the constant for channel i. shift Left shifting factor. 0 <= shift <= 31. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
