"1" defines shape--shape

Shape=rect: Rectangular shape=circle: Round shape=poly: Polygon

"2" Definition area--coords

A. Rectangle: must use four digits, the first two digits are the upper left corner coordinates, the last two digits are the lower right corner coordinates

Example: , 50,200,75 href= "URL" >
