让我们使用一些路径构造，描边和线属性操作符来构建一个简单的图形流：

```
100 100 m 300 200 l 700 100 l % 从坐标 (100, 100) 到 (300, 200) 再到 (700, 100) 创建一条 S 划线
100 100 m 300 200 l 700 100 l % 移动到 (100, 100)，线性移动到 (300, 200)，线性移动到 (700, 100)
S % 绘制线条
8 w % 将线宽从默认值（1.0）更改为8.0
1 J % 将行结束上限从默认方块（代码0）更改为舍入（代码1）
100 200 m 300 300 l 700 200 l % 定义新路径，相同的形状，但在页面上比之前高100点（100pts）处创建一条新的 S 划线
[20] 0 d % 改为20pt破折号
100 300 m 300 400 l 700 300 l % 定义新路径，相同的形状，但在页面上再高100点（100pts）处创建一条新的 S 划线
1 J % 将线的端点样式从默认的方形（码值0）更改为圆形（码值1）

1 J 注释里的默认码值含义写错了。

Line 135 把码值 0 写成“方形”，这会误导读者。这里应是“平头/对接端帽”（而不是方头；方头更接近投射方帽）。

In `@chapter5.md` at line 135, 将注释中的“1 J” 描述修正：把原先把码值 `0`
标注为“方形”的说明替换为准确的术语“平头/对接端帽”（而不是“方头”或“方形”），以正确描述端点样式码值 0；在章内出现 “1 J %
将线的端点样式从默认的方形（码值0）更改为圆形（码值1）” 的注释中直接替换该片段为“平头/对接端帽（码值0）”并保留对码值1为“圆形”的说明。

100 200 m 300 300 l 700 200 l % 定义新路径，形状相同但在页面上高100pt
S % 绘制线条
[20] 0 d % 改为20pt的虚线
100 300 m 300 400 l 700 300 l % 定义新路径，形状相同但在页面上再高100pt
S % 绘制线条
```

结果如图5-2所示。
