La clase CairoContext

(No hay información de versión disponible, podría estar únicamente en SVN)

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.
