# panorama-conversion Specification
|
||
|
||
## Purpose
|
||
TBD - created by archiving change add-panorama-conversion. Update Purpose after archive.
|
||
## Requirements
|
||
### Requirement: Image Empty panorama conversion entry
|
||
|
||
系统 SHALL 在 Image Empty 的 AnyImage 右键菜单展示 `Convert to Panorama`，调用 `anyimage.convert_to_panorama`。
|
||
|
||
#### Scenario: Select panorama conversion
|
||
- **WHEN** 用户选中静态 2:1 Image Empty 并选择 Convert to Panorama
|
||
- **THEN** 提交当前图片及 Alpha 的全景生成任务，使用 Preferences 中的模型、推理级别和分析尺寸
|
||
|
||
#### Scenario: Unsupported image
|
||
- **WHEN** 输入是动画、视频或非 2:1 图片
|
||
- **THEN** 提示输入限制并保留源对象
|
||
|
||
### Requirement: Consume current image alpha
|
||
|
||
转换 SHALL 直接使用当前源图及 Alpha。背景处理由用户通过现有 Remove Background 完成。
|
||
|
||
#### Scenario: Already removed background
|
||
- **WHEN** 源 Empty 的天空已透明
|
||
- **THEN** 当前 Alpha 进入全景任务，转换过程中只运行几何模型
|
||
|
||
### Requirement: Complete conversion transaction
|
||
|
||
系统 SHALL 在主线程加载结果、打包贴图并创建节点对象，成功后替换源 Empty，并提供完整撤销。
|
||
|
||
#### Scenario: Successful conversion
|
||
- **WHEN** Job 返回有效产物
|
||
- **THEN** 创建使用 O Image Panorama 的对象，继承源 Empty 世界变换并以其原点为拍摄中心，激活结果并支持撤销恢复源对象
|
||
|
||
#### Scenario: Cancelled or failed conversion
|
||
- **WHEN** 任务失败、取消或响应时源对象已失效
|
||
- **THEN** 清理本任务暂存及未使用数据块，不应用部分转换结果
