ps_circle — Draws a circle
$psdoc
, float $x
, float $y
, float $radius
)
Draws a circle with its middle point at (x,
y). The circle starts and ends at position
(x+radius,
y). If this function is called outside a path it
will start a new path. If it is called within a path it will add the circle
as a subpath. If the last drawing operation does not end in point
(x+radius,
y) then there will be a gap in the path.
psdoc
Resource identifier of the postscript file as returned by ps_new().
x
The x-coordinate of the circle's middle point.
y
The y-coordinate of the circle's middle point.
radius
The radius of the circle
