NAME
mlib_ImageConstMulShift_Inp - multiply with a constant, with shifting SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstMulShift_Inp(mlib_image *srcdst, const mlib_s32 *c, mlib_s32 shift); DESCRIPTION
The mlib_ImageConstMulShift_Inp() function multiplies each pixel in an image by a constant value on a pixel-by-pixel basis. 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: srcdst[x][y][i] = c[i] * srcdst[x][y][i] * 2**(-shift) PARAMETERS
The function takes the following arguments: srcdst Pointer to source and destination image. c Constant by which each pixel is multiplied. c[i] contains the constant for channel i. shift Right shifting factor. 0 <= shift <= 31. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageConstDivShift_Inp - division into a constant, with shifting SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstDivShift_Inp(mlib_image *srcdst, const mlib_s32 *c, mlib_s32 shift); DESCRIPTION
The mlib_ImageConstDivShift_Inp() function divides each pixel in an image into a constant value on a pixel-by-pixel basis, in place. It scales the result by a left shift and writes the result to the image on a pixel-by-pixel basis. It uses the following equation: srcdst[x][y][i] = c[i] / srcdst[x][y][i] * 2**shift 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, respec- tively. PARAMETERS
The function takes the following arguments: srcdst Pointer to source and destination image. c Constant into 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
