const ctx = canvas.getContext("2d");

ctx.font = "20px Georgia";
ctx.strokeText("Hello World!", 10, 50);

ctx.font = "30px Verdana";

// 创建渐变
const gradient = ctx.createLinearGradient(0, 0, c.width, 0);
gradient.addColorStop("0", "magenta");
gradient.addColorStop("0.5", "blue");
gradient.addColorStop("1.0", "red");
