The CairoContext class
(Èíôîðìàöèÿ î âåðñèè íåèçâåñòíà, âîçìîæíî, òîëüêî â SVN)
Ââåäåíèå
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.
