| * 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. |
