ImagickDraw::pathStart
(PECL imagick 2, PECL imagick 3)
ImagickDraw::pathStart — Declares the start of a path drawing list
说明
public ImagickDraw::pathStart ( ) : bool
Warning 本函数还未编写文档，仅有参数列表。
Declares the start of a path drawing list which is terminated by a matching DrawPathFinish() command. All other DrawPath commands must be enclosed between a and a DrawPathFinish() command. This is because path drawing commands are subordinate commands and they do not function by themselves.
返回值
没有返回值。
