画布尺寸​

Canvas 有两种 width 和 height：

1. 一种是 width、height 属性，一般称其为 画布尺寸，即图形绘制的地方。默认值分别为 300px、150px。

例如：

<canvas id="canvas" width="300" height="150"></canvas>

2. 另一种是 CSS 样式里的 width、height 属性，可通过内联样式、内部样式表或外部样式表设置。一般称其为 画板尺寸，用于渲染绘制完成的图形。默认值为空。

The path element features quite a number of these commands. There are two that are relevant for our purposes:

• Q, which instructs the path to create a quadratic Bézier curve.
• C, which instructs the path to create a cubic Bézier curve.
