OpenCv 1.x绘出CvBox2D

opencv1.x绘制CvBox2D函数(绘制自定义轮廓CvSeq)：

void DrawBox(CvBox2D box,IplImage* img,CvScalar scalar) 
  { 
	  CvPoint2D32f point[4]; 
	  int i; 
	  for ( i=0; i<4; i++) 
	  { 
		  point[i].x = 0; 
		  point[i].y = 0; 
	  } 
	  cvBoxPoints(box, point);
	  CvPoint pt[4]; 
	  for ( i=0; i<4; i++) 
	  { 
		  pt[i].x = (int)point[i].x; 
		  pt[i].y = (int)point[i].y; 
	  } 
	  CvMemStorage* store = cvCreateMemStorage(0);
	  CvSeq* seq = cvCreateSeq(CV_SEQ_ELTYPE_POINT | CV_SEQ_KIND_CURVE | CV_SEQ_FLAG_CLOSED,sizeof(CvContour),sizeof(CvPoint),store);
	  for (size_t i = 0; i < 4; i++)
	  {
		  cvSeqPush(seq,&pt[i]);
	  }
	  cvDrawContours(img,seq,scalar,scalar,1,3,8);
	  cvReleaseMemStorage(&store);
  }
