NAME

mlib_ImageConvKernelConvert - convolution kernel conversion  

SYNOPSIS

cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_ImageConvKernelConvert(mlib_s32 *ikernel, mlib_s32 *iscale,
    const mlib_d64 *fkernel, mlib_s32 m, mlib_s32 n, mlib_type type);

 

DESCRIPTION

The mlib_ImageConvKernelConvert() function converts a floating-point convolution kernel to an integer kernel with its scaling factor suitable to be used in convolution functions.  

PARAMETERS

The function takes the following arguments:

ikernel

Pointer to integer convolution kernel, in row major order.

iscale

Pointer to scaling factor of the integer convolution kernel.

fkernel

Pointer to floating-point convolution kernel, in row major order.

m

Width of the convolution kernel. m ≥ 1.

n

Height of the convolution kernel. n ≥ 1.

type

The image type. It can be one of the following:

MLIB_BIT
MLIB_BYTE
MLIB_SHORT
MLIB_USHORT
MLIB_INT

 

RETURN VALUES

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