嗨，我无法弄清楚这个问题，但下面的例子对我有用。

<!DOCTYPE HTML>
<html>
  <head>
    <style>
      body {
        margin: 0px;
        padding: 0px;
      }
      #myCanvas {
        border: 1px solid #9C9898;
      }
    </style>
    <script>
      window.onload = function() {
        var canvas = document.getElementById("myCanvas");
        var context = canvas.getContext("2d");
        var imageObj = new Image();

        imageObj.onload = function() {
          context.drawImage(imageObj, 69, 50);
        };
        imageObj.src = "http://www.html5canvastutorials.com/demos/assets/darth-vader.jpg";
      };

    </script>
  </head>
  <body>
    <canvas id="myCanvas" width="578" height="400"></canvas>
  </body>
</html>

更改图像的链接。希望它有效。
