<Image>: Optional control name or optional Image, WDPic or picLayer variable
<X1>: Integer X-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels. <Y1>: Integer Y-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels. <X2>: Integer X-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels. <Y2>: Integer Y-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels. <Background color>: Integer or constant (optional) Circle background color.
