我在调整 Raphael.js 中的画布大小时遇到​​了困难。我以为我可以简单地使用：

var paper = Raphael("paper", 100, 100);

这将使用 ID“paper”创建一个宽度和高度为 100 像素的画布。但是，当我尝试这样做时，画布不会使用这些设置进行初始化。我正在使用 Raphael.js 网站上的一些免费图标，我想知道如何更改图标的大小？我是否也必须使用转换功能？如果可以的话，请创建一个 jsfiddle 示例。

提前致谢。

抱歉，如果我没有很好地解释自己，但 Raphael.js 对我来说是全新的。

编辑：

我尝试了您的建议，但无济于事。这是我正在处理的代码。也许我有冲突或什么的。有任何想法吗？

要在标题中回答您的确切问题，您可以使用paper.setSize(width, height)

来自 Raphael 文档：

在此处输入图像描述

你的其他问题有不同的答案。

var paper = Raphael("paper", 100, 100);要求id="paper"您的页面上已有一些 DOM 元素。该 DOM 元素的宽度和高度应足以容纳您的画布（在本例中为 100x100）。或者，您可以省略宽度和高度，它将采用容器的宽度和高度（非常方便）。您还可以通过放入所有四个维度来生成没有 DOM 元素的画布，例如var paper = Raphael(0, 0, 100, 100);在文档的左上角制作一个 100x100 的画布。

要调整 Raphael 图标的大小，您可以使用变换功能。例如icon.transform("s2");使它变大两倍。

这个小提琴展示了如何创建一个 Raphael 画布并将铅笔图标放在上面，使其变为黄色并放大两倍。请注意，我们需要围绕左上角缩放（通常它围绕中心缩放）以防止它从页面的顶部和左侧剪掉。

var pencil = "M25.31,2.872l-3.384-2.127c-0.854-0.536-1.979-0.278-2.517,0.576l-1.334,2.123l6.474,4.066l1.335-2.122C26.42,4.533,26.164,3.407,25.31,2.872zM6.555,21.786l6.474,4.066L23.581,9.054l-6.477-4.067L6.555,21.786zM5.566,26.952l-0.143,3.819l3.379-1.787l3.14-1.658l-6.246-3.925L5.566,26.952z"
