+ * 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.
