示例1: bounding_box

/**********************************************************************
 * TBLOB::bounding_box()
 *
 * Compute the bounding_box of a compound blob, defined to be the
 * bounding box of the union of all top-level outlines in the blob.
 **********************************************************************/
TBOX TBLOB::bounding_box() const {
  if (outlines == nullptr) return TBOX(0, 0, 0, 0);
  TESSLINE* outline = outlines;
  TBOX box = outline->bounding_box();
  for (outline = outline->next; outline != nullptr; outline = outline->next) {
    box += outline->bounding_box();
  }
  return box;
