ft.run(main)枚举值
| 名称 | 类型 | 默认值 | 说明 |
|---|---|---|---|
FILL | — | 'fill' | Paint the interior of the shape. For example, circles and polygons are rendered as solid filled regions. |
STROKE | — | 'stroke' | Paint only the shape outline. Stroke thickness and joins/caps are controlled by properties such as stroke_width, stroke_join, and stroke_cap. |
