# The CairoContext class

## 導入

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.
