    La clase CairoContext

    (PECL cairo >= 0.1.0)

    Introducción

    Context (contexto) es el objeto principal usado cuando se dibuja con cairo. Para dibular con cairo, se crea un CairoContext, se establece el CairoSurface objetivo, y las opciones de dibujo para el CairoContext, se crean formas con funciones, como CairoContext::moveTo() y CairoContext::lineTo(), y despúes se dibujan formas con CairoContext::stroke() o CairoContext::fill(). Los contextos de pueden intorducir en una pila mediante CairoContext::save(). Entonces se pueden cambiar de forma segura, sin perder el estado actual. Use CairoContext::restore() para restaurar el estado guardado.
