/*
 * FUNCTIONS
 *      mlib_ImageConvClearEdge  - Set edge of an image to a specific
 *                                        color. (VIS version)
 *
 * SYNOPSIS
 *      mlib_status mlib_ImageConvClearEdge(mlib_image     *dst,
 *                                          mlib_s32       dx_l,
 *                                          mlib_s32       dx_r,
 *                                          mlib_s32       dy_t,
 *                                          mlib_s32       dy_b,
 *                                          const mlib_s32 *color,
 *                                          mlib_s32       cmask)
 *
 * ARGUMENT
 *      dst       Pointer to an image.
 *      dx_l      Number of columns on the left side of the
 *                image to be cleared.
 *      dx_r      Number of columns on the right side of the
 *                image to be cleared.
 *      dy_t      Number of rows on the top edge of the
 *                image to be cleared.
 *      dy_b      Number of rows on the top edge of the
 *                image to be cleared.
 *      color     Pointer to the color that the edges are set to.
 *      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.
 *
 * RESTRICTION
 *      dst can have 1, 2, 3 or 4 channels of MLIB_BYTE or MLIB_SHORT or MLIB_INT
 *      data type.
 *
 * DESCRIPTION
 *      Set edge of an image to a specific color. (VIS version)
 *      The unselected channels are not overwritten.
 *      If src and dst have just one channel,
 *      cmask is ignored.
