Halcon获得图像指针

1. Hlong width,height;
   
2. HObject ho_image;
   
3. ReadImage(&ho_image, path.c_str());
   
4. ConvertImageType(ho_image, &ho_image, "real");    //转化为float的数据
   
5. HImage hImg(ho_image);
   
6. HString ho_type;
   
7. void *ptr_img = hImg.GetImagePointer1(&ho_type, &width, &height);        //获取float的指针
   
8. 
   
9. HTuple hv_pointer;
   
10. unsigned char *ptr;
    
11. GetImagePointer1(himage,&hv_pointer,&htype,&width,&height);
    
12. ptr=(unsigned char *)hv_pointer[0].L();
    
13. 
    
14. HTuple hv_ptrRed,hv_ptrGreen,hv_ptrBlue;
    
15. GetImagePointer3(himage,&hv_ptrRed,&hv_ptrGreen,&hv_ptrBlue,&htype,&width,&height);
    
16. uchar *ptrRed=(uchar*)hv_ptrRed[0].L();
    
17. uchar *ptrGreen=(uchar*)hv_ptrGreen[0].L();
    
18. uchar *ptrBlue=(uchar*)hv_ptrBlue[0].L();
