本文介绍了canvas绘制表情包的示例代码，分享给大家，具体如下：

绘制卡通笑脸

var canvas = document.getElementById(canvas);var context = canvas.getContext(2d);// 画脸,设置脸的填充颜色为 #fffcontext.fillStyle = #fff;context.beginPath();context.arc(150, 150, 60, 0, Math.PI*2);context.closePath();context.fill();// 画眼睛,设置眼睛的填充颜色为 rgb(0, 0, 0)context.fillStyle = rgb(0, 0, 0);context.beginPath();context.arc(130, 130, 8, 0, Math.PI*2);context.closePath();context.fill();context.fillStyle = rgb(0, 0, 0);context.beginPath();context.arc(170, 130, 8, 0, Math.PI*2);context.closePath();context.fill();// 画嘴巴,设置嘴巴的填充颜色为 rgba(255, 0, 0, 0.8)context.fillStyle = rgba(255, 0, 0, 0.8);context.beginPath();context.arc(150, 160, 25, Math.PI, Math.PI*2, true);context.closePath();context.fill();// 画腮红,设置腮红线条颜色为 pink,线条宽度为 5context.beginPath();context.moveTo(95, 152);context.lineTo(110, 150);context.moveTo(190, 150);context.lineTo(205, 152);context.closePath();context.lineWidth = 5;context.strokeStyle = pink;context.stroke();

制作表情包

var canvas = document.getElementById(canvas);var context = canvas.getContext(2d);var image = new Image();image.src= https://ke.qq.com/classroom/assets/lib/img/canvas-expression-base.png;image.onload = function(){  context.drawImage(image, 50, 110, 200, 200);}context.font = 30px arial;context.fillText(今天的我, 20, 50);context.font = 40px arial;context.fillText(还是一样的帅！, 20, 90);
