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.
