 * @ingroup IMGPROC_DIST
 * @brief 8-connected distance transformation of a binary image,
 *   for black components only.
 *
 * @warning The result is stored in a grey-level image:
 * As grey-level images are coded with <b>256</b> levels, images
 * containing black components bigger than <b>510*510</b> are not
 * correctly supported.
 *
 * @todo
 * - In constructor code, use pixel map pointers instead of nested
 *   loops (for iCnt and for jCnt) to get less tests (and thus save time).
 * - The constructor performs a copy of the given image: If it is a
 *   deep copy, is it really necessary?
 * - Given binary image <b>must</b> exclusively contain 0's and 1's.
