# Mask Alpha 编辑
|
||
|
||
`operators/mask_tool.py` 定义 `EditImageAlpha` 和 `MaskTool`，使用 `common/viewport.py` 的 `ImageGesture` 管理 Lasso、Brush 与 Polyline。
|
||
|
||
```mermaid
|
||
flowchart TD
|
||
A[冻结 Scene 的 Gesture、Mode、Radius] --> B[屏幕手势与 Overlay]
|
||
B --> C[完成后投影并生成覆盖 M]
|
||
C --> D[读取源 RGBA]
|
||
D --> E[按模式计算 Alpha]
|
||
E --> F[保留 RGB 和源画布尺寸]
|
||
F --> G[替换 Packed Image 并提交一个 Undo]
|
||
```
|
||
|
||
| 模式 | 源 Alpha A 与覆盖 M 的结果 |
|
||
| --- | --- |
|
||
| Set | `A × M` |
|
||
| Add | `max(A, M)` |
|
||
| Subtract | `A × (1 − M)` |
|
||
|
||
Brush 拖动时维护简化屏幕路径、圆形印记与连接条的并集预览；释放时一次生成图片覆盖。Polyline 使用逐点路径，至少三个点后通过闭合圈、双击或 Enter 完成，Backspace 删除末点。
|
||
|
||
结果保留 Empty 的身份、矩阵、显示尺寸和偏移。全透明结果有效，取消或切换工具清理未提交的 Overlay；共享 Image 通过统一替换入口分流。
