| * FUNCTION | |
| * mlib_ImageConvMxN_Fp - image convolution with edge condition | |
| * | |
| * SYNOPSIS | |
| * mlib_status mlib_ImageConvMxN_Fp(mlib_image *dst, | |
| * const mlib_image *src, | |
| * const mlib_d64 *kernel, | |
| * mlib_s32 m, | |
| * mlib_s32 n, | |
| * mlib_s32 dm, | |
| * mlib_s32 dn, | |
| * mlib_s32 cmask, | |
| * mlib_edge edge) | |
| * | |
| * ARGUMENTS | |
| * dst Pointer to destination image. | |
| * src Pointer to source image. | |
| * m Kernel width (m must be not less than 1). | |
| * n Kernel height (n must be not less than 1). | |
| * dm, dn Position of key element in convolution kernel. | |
| * kernel Pointer to convolution kernel. | |
| * cmask Channel mask to indicate the channels to be convolved. | |
| * Each bit of which represents a channel in the image. The | |
| * channels corresponded to 1 bits are those to be processed. | |
| * edge Type of edge condition. | |
| * | |
| * DESCRIPTION | |
| * 2-D convolution, MxN kernel. | |
| * | |
| * The center of the source image is mapped to the center of the | |
| * destination image. | |
| * The unselected channels are not overwritten. If both src and dst have | |
| * just one channel, cmask is ignored. | |
| * | |
| * The edge condition can be one of the following: | |
| * MLIB_EDGE_DST_NO_WRITE (default) | |
| * MLIB_EDGE_DST_FILL_ZERO | |
| * MLIB_EDGE_DST_COPY_SRC | |
| * MLIB_EDGE_SRC_EXTEND | |
| * | |
| * RESTRICTION | |
| * The src and the dst must be the same type and have same number | |
| * of channels (1, 2, 3, or 4). | |
| * m >= 1, n >= 1, | |
| * 0 <= dm < m, 0 <= dn < n. | |
