当我在带有通过@ font-face加载的字体的画布上绘制文本时,文本无法正确显示.它根本不显示(在Chrome 13和Firefox 5中),或者字体错误(Opera 11).此类意外行为仅在第一次使用字体绘图时发生.之后一切正常.
这是标准行为还是什么？
谢谢.
PS:以下是测试用例的源代码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>@font-face and <canvas></title>
<style id="css">
@font-face {
font-family: 'Press Start 2P';
src: url('fonts/PressStart2P.ttf');
}
</style>
<style>
canvas, pre {
border: 1px solid black;
padding: 0 1em;
}
</style>
</head>
<body>
<h1>@font-face and <canvas></h1>
<p>
