代码应用场景介绍

本段代码使用 RoughJS 库在 HTML5 Canvas 上创建了手绘风格的图像，展示了 RoughJS 库的强大功能，可用于创建具有有机手绘外观的图形。

代码基本功能介绍

代码通过 RoughJS 库创建了一个火焰状的图形，包括：

• 火焰主体：使用 path() 函数绘制，采用不规则的形状和粗糙的线条。
• 火焰细节：添加了额外的 path()，例如线条和点，以增强火焰的纹理和深度。
• 阴影效果：通过使用较浅的填充色在火焰周围绘制阴影，营造出立体感。

功能实现步骤及关键代码分析说明

1. 初始化 RoughJS

const rc = rough.canvas(document.getElementById('canvas'),window.innerWidth,window.innerHeight,
)

此代码初始化 RoughJS 库，并创建一个 RoughCanvas 实例 rc，用于在 HTML5 Canvas 上绘制。

2. 绘制火焰主体

)

此代码使用 path() 函数绘制火焰主体，路径形状复杂，模拟了火焰的不规则形状。

3. 添加火焰细节
