The Canvas API is a low level API for drawing. It lets you create lines, curves, polygons, and circles and fill them in with colors, gradients, and so on.───Canvas API是一个低级画图api，它支持创建直线、曲线、多边形和圆圈，并用彩色、渐变色等填充它们。
You define the fixed size of the canvas in the element itself, and then typically you do the actual drawing from a script that uses the canvas API to create visual objects on the canvas.───首先在元素本身中定义画布的固定大小，然后利用使用 canvas API 在画布上创建可视化对象的脚本来实际绘画。
Although most of the SWT API can be implemented, some things such as drawing on the canvas or detection of mouse movement will have to await further browser enhancements in these areas.───尽管大多数的SWT API都能被实现，但像在画布上描绘以及探测鼠标移动等功能还有待于浏览器在这些方面的进一步改善和提高。
The report graphic is generated on the fly using the Canvas API.───这个报告图形是使用这个CanvasAPI实时生成的。
