 相比单调的填充色，使用纹理填充能丰富表现力，在无障碍和黑白打印场景下也有不错的应用。为此我们提供了以下三种方式，按使用成本从简到难依次为：
-* 使用内置纹理
-* 使用 G API 自定义纹理
-* 使用其它纹理来源

 ## 使用内置纹理
 
 我们在 [g-pattern](https://g.antv.antgroup.com/api/css/pattern#g-pattern) 中内置了常见的三种纹理，通过参数可以便捷地调整外观，这也是最简单的一种纹理使用方式：
 
-* [dots](https://g.antv.antgroup.com/api/css/pattern#dots) 由圆点构成
-* [lines](https://g.antv.antgroup.com/api/css/pattern#lines) 由直线构成

 然后就可以使用其中的内置纹理了。在该[示例](/zh/examples/theme/pattern#lines-pattern)中：
-* 我们使用了 [lines](https://g.antv.antgroup.com/api/css/pattern#lines)，设置了背景颜色、透明度、直线颜色以及间距等属性
-* 通过 [repetition](https://g.antv.antgroup.com/api/css/pattern#repetition) 指定了平铺方式为水平和垂直方向
-* 通过 [transform](https://g.antv.antgroup.com/api/css/pattern#transform) 让纹理顺时针旋转 30 度
