h
Ellipse height, measured in dot
rows. Must be greater than zero.
Optional; specifies line thickness in
dots. The default is 1. If t is greater
than 1, the x, y, w, and h parameters
refer to the box outside dimensions.
t
c

Comments
DRAW_ELLIPSE
can draw a rectangle enclosing an
ellipse if you set t and h or w equal to 1, but the
lines are two dots wide. Figures drawn with this
command may not print well at 200 DPI or higher
resolution unless the t parameter is 2 or more.
Some early printers do not support the t parameter,
in which case we suggest using multiple
FILL_ELLIPSE
commands to create boxes with
thicker lines.
