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.
Parameters
- 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
Return Values
Returns TRUE
on success or FALSE
on failure.
