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.
