如何在IE中使用HTML5 canvas元素？ [英] How can I use the HTML5 canvas element in IE?

问题描述

我试图使用HTML5 canvas元素来绘制一些弧和圆 - 这在FF中是完美的，但IE8似乎不支持它。

I am trying to use the HTML5 canvas element to draw some arcs and circles - this works perfectly in FF but IE8 does not seem to support it.

有存在的Javascript库似乎使IE8与Canvas工作得很好。 此处可以找到一个示例。

Now, there exist Javascript libraries which seem to make IE8 work well with Canvas. An example can be found here.

我已经阅读了他们的整个来源，但我不明白他们是如何使Canvas工作与IE8。
