# CanvasContext.setStrokeStyle(string|[CanvasGradient](/miniprogram/dev/api/canvas/CanvasGradient) color)

CanvasContext 是旧版的接口，新版 [Canvas 2D](/miniprogram/dev/component/canvas.md) 接口与 Web 一致

从基础库 [1.9.90](1003706) 开始，本接口停止维护，请使用 [CanvasContext.strokeStyle](/miniprogram/dev/api/canvas/CanvasContext) 代替

> __小程序插件__：支持
