Var image=new Image();
image.src=” ”;
image.onload=function(){}
Context.drawImage(image,x,y);
Context.drawImage(image,x,y,w,h);
Context.drawIamge(image,sx,sy,sw,sh,dx,dy,dw,dh);
图片平铺
Var pat= context.createPattern(image,”repeat”);
Context.fillStyle=pat;
Context.fillRect(0,0,400,300);
图片裁剪
先绘制好路径
Context.clip();
<html> <head> <meta charset="UTF-8"> <title>绘制图片</title> <meta content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" /> </head> <body> <canvas></canvas> <script type="text/javascript"> var oCanvas = document.getElementById("canvas"); var context = oCanvas.getContext("2d"); context.fillStyle = "#ededed"; context.fillRect(0, 0, 500, 500); //绘制图片 var img = new Image(); //创建 img.src = "img/01.jpg"; //图片地址 img.onload = function() { //检测所有图像信息载入页面里 context.drawImage(img, 0, 0); // img对象;0,0:img坐标起点 }; </script> </body> </html>
