halcongen_region_points获取点区域

在HDevelop中

dev_open_window (0, 0, 300, 300, 'black', WindowHandle)

gen_region_points (Region1, [100,100,100,100,100,100], [100,101,102,103,104,105])
*获取点区域
*参数1：输出区域
*参数2：点的y坐标
*参数3：点的x坐标

dev_display(Region1)

在Qt Creator中

    HObject  ho_Image, ho_Image1, ho_Region, ho_RegionComplement;
    HTuple  hv_Width, hv_Height, hv_WindowHandle;
    HTuple  hv_WindowHandle1;

    
    ReadImage(&ho_Image, "D:/bb/tu/4.jpg");
    Rgb1ToGray(ho_Image, &ho_Image1);
    //将RGB图像转换为灰度图像
  
    Threshold(ho_Image1, &ho_Region, 80, 90);
  
  
    Complement(ho_Region, &ho_RegionComplement);
    //区域的补集--获取参数1之外的区域
  
  
  
    GetImageSize(ho_Image1, &hv_Width, &hv_Height);
  
    SetWindowAttr("background_color","black");
    OpenWindow(10,100,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle);
