计算每个区域的面积，并保存到本地txt；

dev_close_window ()
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)

dev_open_file_dialog ('read_image', 'default', 'default', Selection)
read_image (MyImage, Selection)

regiongrowing (MyImage, Regions, 3, 3, 6, 100)
count_obj (Regions, Number)
open_file ('D:/Pic_Halcon_Avs_Vs/Information.txt', 'output', FileHandle)

for Index := 1 to Number by 1
    select_obj (Regions, ObjectSelected, Index)
    area_center (ObjectSelected, Area, Row, Column)
    fwrite_string (FileHandle, Index+'---'+Area)
    fnew_line (FileHandle)
    
    
    
endfor
