Draws a circle - Справочник: PHP5.4

Описание

bool ps_circle ( resource $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.

Список параметров

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
