<p class="MsoNormal">I am trying to create a python script to get an image file as below:<o:p></o:p></p>

<p class="MsoNormal">But I got the default image file name, map.png with GRASS_WIDTH=640 and GRASS_HEIGHT=480.<o:p></o:p></p>
<p class="MsoNormal">Is there any way for me to setup width and height and my image file name in grass.run_command?<o:p></o:p></p>
<p class="MsoNormal">I searched the doc for a while but I still can not get a correct syntax.<o:p></o:p></p>
