NAME
mlib_ImageConstMul_Fp_Inp - multiply with a constant SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstMul_Fp_Inp(mlib_image *srcdst, const mlib_d64 *c); DESCRIPTION
The mlib_ImageConstMul_Fp_Inp() function multiplies each pixel in a floating-point 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] 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. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageConstDivShift_Inp(3MLIB)			    mediaLib Library Functions				mlib_ImageConstDivShift_Inp(3MLIB)

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
