Draws an arc counterclockwise

설명

bool ps_arc ( resource $psdoc , float $x , float $y , float $radius , float $alpha , float $beta )

Draws a portion of a circle with at middle point at (x , y ). The arc starts at an angle of alpha and ends at an angle of beta . It is drawn counterclockwise (use ps_arcn() to draw clockwise). The subpath added to the current path starts on the arc at angle alpha and ends on the arc at angle beta .

인수

x: The x-coordinate of the circle's middle point.
y: The y-coordinate of the circle's middle point.
