The mlib_ImageConvKernelConvert() function converts a floating-point convolution kernel to an integer kernel with its scaling factor suit- able 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. ATTRIBUTES

NAME
mlib_ImageConvMxN - MxN convolution SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConvMxN(mlib_image *dst, const mlib_image *src, const mlib_s32 *kernel, mlib_s32 m, mlib_s32 n, mlib_s32 dm, mlib_s32 dn, mlib_s32 scale, mlib_s32 cmask, mlib_edge edge); DESCRIPTION
The mlib_ImageConvMxN() function performs a MxN convolution on the source image by using the user-supplied kernel. The input image and the output image must have the same image type and have the same number of channels. The unselected channels in the output image are not overwritten. For single-channel images, the channel mask is ignored. For this convolution, the key element of the convolution kernel is located at (dm, dn) of the kernel matrix. It uses the following equation: m-1-dm n-1-dn dst[x][y][i] = SUM SUM src[x+p][y+q][i]*k[p][q]*2**(-scale) p=-dm q=-dn where m >= 1, n >= 1, 0 <= dm < m, 0 <= dn < n. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. kernel Pointer to the convolution kernel, in row major order. m Width of the convolution kernel. m >= 1. n Height of the convolution kernel. n >= 1. dm X coordinate of the key element in the convolution kernel. 0 <= dm < m. dn Y coordinate of the key element in the convolution kernel. 0 <= dn < n. scale Scaling factor. cmask Channel mask to indicate the channels to be convolved, each bit of which represents a channel in the image. The channels corre- sponding to bits with a value of 1 are those to be processed. For a single-channel image, the channel mask is ignored. edge Type of edge condition. It can be one of the following: MLIB_EDGE_DST_NO_WRITE MLIB_EDGE_DST_FILL_ZERO MLIB_EDGE_DST_COPY_SRC MLIB_EDGE_SRC_EXTEND RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
