the line width is large, the entire interior of the rectangle may be part of the outline region. The outline width
expands around the perimeter of the rectangle. For example, if the width is 4 pixels, 2 pixels will be inside the
rectangle and 2 pixels will be outside the rectangle. When the outline width is set to zero there is no outline. When
the outline is transparent the fill Color will be seen in part of the outline.
The Fill Color parameters are set by the
FC=white and FA=nnn
.
3.8.4.2 Example of Drawing an Ellipse.
The following Rectangle Field Display Command string will draw a blue rectangle with a green outline
:
G ID=1 S=rectangle X=100 Y=100 H=880 L=1720 FC=blue FA=80 OC=green OA=60 OW=4
3.8.4.3 Circle and Ellipse Shapes
The circle and ellipse shapes are very similar. The ellipse uses the height and length to determine the proportions
and the circle uses only the length.
The X, Y anchor location is set in the center of the circle and ellipse

3.8.4.4 Line Shape
The Line Shape starting position is at X, Y with the end point being specified by the length (L) and the width (W)
specified by the height (H) starting from a specified X,Y coordinate position.
. The Line Shape has no outline that surrounds it. Lines can have an end cap which can be flat or round. Lines
are always drawn horizontally left to right with a rotation angle of zero degrees. To draw a vertical line you would
rotate the line 90 degrees which can be positive or negative. Positive rotations are clockwise.
