PHP5中文手册·Draws a circle -- 追寻梦想＞编程乐园＞PHP 编程

说明

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.

参数

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

返回值

如果成功则返回 TRUE，失败则返回 FALSE。
