ImagickDraw::pathStart — Declares the start of a path drawing list

Descrizione

public ImagickDraw::pathStart(): bool

Avviso

Questa funzione, al momento non è documentata; è disponibile soltanto la lista degli argomenti.

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.
