[GRASS-user] Problem with v.digit

[yazid bekti]

Hello , i'm undergraduate and for my research of
landscape i using the v.digit to digit the satelite
image, but i find very difficult to use this tool
(maybe because i don't have the basic concept). i have
using common boundary but still some time there
problems because the area won't close (stiil gray
color, i dont change the color of v.digit). can
someone tell me how to use this tool and where should
i start the digit. In the middle of satelite image or
in the corner. 
thank you very much
