# Rectify 透视校正
|
||
|
||
`operators/rectify_tool.py` 定义 `RectifyImagePerspective` 与 `RectifyTool`，将图片内的四角区域校正为矩形。
|
||
|
||
```mermaid
|
||

|
||
A[点选四角] --> B[规范为凸 Quad 并检查图片交叠]
|
||
B --> C[512×512 预览与宽高比调整]
|
||
C --> D[按像素密度和输出上限确定尺寸]
|
||
D --> E[分块 Homography 与预乘 Alpha 插值]
|
||
E --> F[按可见 Alpha 裁剪]
|
||
F --> G[映射 placement bounds 并替换 Packed Image]
|
||
```
|
||
|
||
四角允许任意点击顺序，退化或非凸输入在提交前校验。预览根据源颜色空间配置显示，像素重采样复用 `common/image.py`。输出最长边上限 8192，总像素上限 16,777,216。
|
||
|
||
`replace_empty_image()` 根据校正区域的 placement bounds 调整画框，保留源 Image 名称、对象身份和共享引用语义。
