NAME
mlib_ImageConstMulShift - multiply with a constant, with shifting SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstMulShift(mlib_image *dst, const mlib_image *src, const mlib_s32 *c, mlib_s32 shift); DESCRIPTION
The mlib_ImageConstMulShift() 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: dst[x][y][i] = c[i] * src[x][y][i] * 2**(-shift) PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source 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
