mlib_ImageConstMulShift_Inp(3MLIB) mediaLib Library Functions mlib_ImageConstMulShift_Inp(3MLIB)NAMEmlib_ImageConstMulShift_Inp - multiply with a constant, with shiftingSYNOPSIScc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstMulShift_Inp(mlib_image *srcdst, const mlib_s32 *c, mlib_s32 shift);DESCRIPTIONThe 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)PARAMETERSThe 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 VALUESThe function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOmlib_ImageConstMul(3MLIB), mlib_ImageConstMul_Fp(3MLIB), mlib_ImageConstMul_Fp_Inp(3MLIB), mlib_ImageConstMul_Inp(3MLIB), mlib_ImageConst- MulShift(3MLIB), attributes(5) SunOS 5.10 10 Nov 2004 mlib_ImageConstMulShift_Inp(3MLIB)
