HTML5 Canvas 扭曲
htmljavascriptprogramming scripts
如果 Canvas 看起来扭曲了，请尝试更改高度和宽度 −
<canvas id = ”canvas1” width = '400' height = '300'></canvas>
HTML5 中 Canvas 的默认高度和宽度比例为 2/1 −
width = 300 height = 150
示例
让我们看一个例子 −
<!DOCTYPE HTML>
<html>
<head>
<style>
#mycanvas{border:1px solid red;}
</style>
</head>
<body>
<canvas id = "mycanvas" width = "100" height = "100"></canvas>
</body>
</html>
输出
