我有一个画布覆盖的图像。图像和画布都包含在缩放的div中。在画布上绘图时,图像变得非常模糊。你有任何想法如何摆脱模糊? 请看这个小提琴:
<body>
<div style="position: relative; transform: scaleX(2) scaleY(2) ">
<div class="pagecontainer" style=" width: 125px; height: 100px; position: absolute; top:0px; left:400px">
<img src="http://www.maxrev.de/files/2011/02/testbild_1297949508.jpg" width="125" height="100" >
</div>
<div style="position: absolute; left: 400px; top:0px;width: 125px; height:150px;">
<canvas id="supercanvas" width="125" height="150" style="width:125px; height:125px"></canvas>
</div>
</div>
<script>
document.getElementById("supercanvas").getContext("2d").fillRect(80, 80, 80, 80);
</script>
</body>
