ImagickDraw::pathStartDeclares the start of a path drawing list

说明

public ImagickDraw::pathStart(): bool
警告

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。
