# CairoContext クラス

(PECL cairo >= 0.1.0)

## 導入

コンテキストは、cairo での描画に使うメインオブジェクトです。 cairo で描画を行うには、 CairoContext を作ってから対象の CairoSurface を設定し、CairoContext の描画オプションを設定します。 CairoContext::moveTo() や CairoContext::lineTo() などの関数でシェイプを作成し、 CairoContext::stroke() や CairoContext::fill() でシェイプを描画します。 コンテキストをスタックにプッシュするには CairoContext::save() を使います。これで、現状を失わずに安全に変更できるようになります。 保存した状態を復元するには CairoContext::restore() を使います。
