The CairoContext class
(PECL cairo >= 0.1.0)
简介
Context is the main object used when drawing with cairo. To draw with cairo, you create a CairoContext, set the target CairoSurface, and drawing options for the CairoContext, create shapes with functions . like CairoContext::moveTo() and CairoContext::lineTo() , and then draw shapes with CairoContext::stroke() or CairoContext::fill() . Contexts can be pushed to a stack via CairoContext::save() . They may then safely be changed, without loosing the current state. Use CairoContext::restore() to restore to the saved state.
