mlib_status mlib_ImageConstMul_Fp(mlib_image *dst, const mlib_image *src,
     const mlib_d64 *c);

Description

The mlib_ImageConstMul_Fp() function multiplies each pixel in a floating-point image by a constant value on a pixel-by-pixel basis.

It uses the following equation:

dst[x][y][i] = c[i] * src[x][y][i]

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.

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
