Fills a polygon in the LCD page buffer and on the LCD if the buffer is unlocked. Any portion of the
polygon that is outside the LCD display area will be clipped. If fewer than 3 vertices are specified, the
function will return without doing anything.
PARAMETERS
n
is the number of vertices.
x1
is the x coordinate of the first vertex.
y1
is the y coordinate of the first vertex.
x2
is the x coordinate of the second vertex.
y2
is the y coordinate of the second vertex.
...
are the coordinates of additional vertices.
RETURN VALUE
None.
SEE ALSO

Draws the outline of a circle in the LCD page buffer and on the LCD if the buffer is unlocked. Any por-
tion of the circle that is outside the LCD display area will be clipped.
PARAMETERS
xc
is the x coordinate of the center of the circle.
yc
is the y coordinate of the center of the circle.
rad
is the radius of the center of the circle (in pixels).
RETURN VALUE
None.
