- Added a new cutout tool for selecting regions in images, allowing users to choose mesh shapes based on selected areas. - Introduced depth generation capabilities for rasterized images, including normal data extraction. - Created jobs for generating depth planes and region data, enhancing the AI data generation workflow. - Developed a selection refinement process for cutout regions, improving accuracy in generated outputs. - Established a new region module for handling rasterized image regions and their associated AI generation tasks. - Enhanced node graph builders for asset generation, facilitating smoother integration of new features.

# Upscale
|
||
|
||
本页对应 `src/anyimage/operators/upscale.py`。该模块读取扩展首选项中的模型与全局 AI 输入长边上限,检查当前 Image 是否可处理,再提交 4× 高清任务。
|
||
|

## 主流程

```mermaid

||
flowchart TD
|
||
Empty["Image Empty"] --> Source["读取当前 Image"]
|
||
Source --> Gate{"当前长边小于全局上限?"}
|
||
Gate -- "否" --> Disabled["Upscale 置灰"]
|
||
Gate -- "是" --> Prepare["准备媒体输入"]
|
||
Prepare --> Job["upscale-image Job"]
|
||
Job --> RGB["分块执行 4× RGB 推理"]
|
||
Job --> Alpha["独立缩放 Alpha"]
|
||
RGB --> Merge["合并 RGBA 结果"]
|
||
Alpha --> Merge
|
||
Merge --> Replace["导入并替换当前 Image"]
|
||
```
|
||
|
||
模型以 256×256 分块处理 RGB,并带入相邻上下文以减弱块边界;Alpha 不进入模型,使用 Lanczos 独立放大后合并为 RGBA。`max_input_size` 来自全局 **Maximum AI Input Size**,默认 `2048`。Operator 只允许当前 Image 长边小于该值时执行,因此正式流程不会预缩放输入,4× 输出长边小于上限的四倍。Server 仍保留相同上限作为任务边界。
|
||
|
||
菜单根据当前尺寸只显示预计的 4× 结果尺寸。结果通过与 Remove Background、Image Mask 和 Perspective 相同的 Image Empty 替换入口处理:原 Image 没有其他用户且未启用 Fake User 时,移除旧数据并让结果沿用原名;存在其他用户时保留原 Image,并只让当前 Empty 使用独立结果。结果不增加 Upscale 专属后缀,也不保存来源引用。后续 Upscale 与 Depth Plane 都读取当前 Image。模型与全局输入上限在每次执行时从 Preferences 读取,再写入可序列化的隐藏属性交给 Job。Provider 资源错误会释放当前 Upscale Session,并提示降低全局输入上限或改用 CPU。
