NAME
mlib_ImageSConvKernelConvert - kernel conversion for separable convolution SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSConvKernelConvert(mlib_s32 *ihkernel, mlib_s32 *ivkernel, mlib_s32 *iscale, const mlib_d64 *fhkernel, const mlib_d64 *fvkernel, mlib_s32 m, mlib_s32 n, mlib_type type); DESCRIPTION
The mlib_ImageSConvKernelConvert() function converts a floating-point separable convolution kernel to an integer kernel with its scaling factor, which is suitable to be used in separable convolution functions. PARAMETERS
The function takes the following arguments: ihkernel Pointer to integer horizontal kernel. ivkernel Pointer to integer vertical kernel. iscale Scaling factor of the integer convolution kernel. fhkernel Pointer to floating-point horizontal kernel. fvkernel Pointer to floating-point vertical kernel. m Width of the convolution kernel. m must be an odd number larger than 1. n Height of the convolution kernel. n must be an odd number larger than 1. type The image type. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageSConv3x3 - separable 3x3 convolution SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSConv3x3(mlib_image *dst, const mlib_image *src, const mlib_s32 *hkernel, const mlib_s32 *vkernel, mlib_s32 scale, mlib_s32 cmask, mlib_edge edge); DESCRIPTION
The mlib_ImageSConv3x3() function performs a separable 3x3 convolution on the source image by using the user-supplied kernel. It uses the following equation: m-1-dm n-1-dn dst[x][y][i] = SUM SUM src[x+p][y+q][i]*h[p]*v[q]*2**(-2*scale) p=-dm q=-dn where m = 3, n = 3, dm = (m - 1)/2 = 1, dn = (n - 1)/2 = 1. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. hkernel Pointer to the horizontal kernel. vkernel Pointer to the vertical kernel. 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 corresponding to one bits 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
