# Meitu Cutout

## Overview

调用 `meitu image-cutout` 从图片中分离前景主体,输出透明背景 PNG。支持人像、商品、图形三种模式,可自动检测。

## Dependencies

- **meitu-cli**: `npm install -g meitu-cli`
- **凭证**: `meitu config set-ak --value "..."` / `meitu config set-sk --value "..."`, 或 env vars `MEITU_OPENAPI_ACCESS_KEY` / `MEITU_OPENAPI_SECRET_KEY`

> **路径别名:** 下文中 `$VISUAL` = `{OPENCLAW_HOME}/workspace/visual/`

## Core Workflow

```
Preflight → [Context: 跳过(工具型抠图,无创意自由度)] → Execute → Deliver
```

### Preflight

1. `meitu --version` → 未安装则提示 `npm install -g meitu-cli`
2. `meitu auth verify --json` → 凭证无效则引导配置
3. Detect mode: cwd has `openclaw.yaml` → project mode; else → one-off
   检查 `$VISUAL` 目录 → 确定 capabilities
4. output_dir 解析(Preflight 内 MUST 完成):
   Resolve output_dir: openclaw.yaml → `./output/` | else → `$VISUAL/output/meitu-cutout/`
   `mkdir -p {output_dir}`

### Execute

**输入解析**

用户提供图片,支持两种形式:
- 本地文件路径(如 `./photo.jpg`)
- 图片 URL(如 `https://example.com/photo.jpg`)

如果用户只说"帮我抠图"但没给图片 → 问:"请提供需要抠图的图片(本地路径或 URL)"。

**model_type 路由**

| 用户意图 / 图片内容 | model_type | 说明 |
|---------------------|-----------|------|
| 人像、证件照、半身照 | `0` (portrait) | 人像优化,保留发丝细节 |
| 商品、产品、电商图 | `1` (product) | 产品边缘优化 |
| 设计素材、图标、插画 | `2` (graphic) | 图形/非照片类 |
| 不确定 / 未说明 | 不传 | 自动检测(推荐默认) |

规则:用户未指定类型时,不传 `--model_type`,让服务端自动检测。仅当用户明确说"这是人像/商品/图标"或图片来源明确(如"电商主图")时才指定。

**工具调用**

单张抠图:
```bash
meitu image-cutout --image {image_url_or_path} --json --download-dir {output_dir}
```

指定 model_type:
```bash
meitu image-cutout --image {image_url_or_path} --model_type {0|1|2} --json --download-dir {output_dir}
```

**批量处理**

用户提供多张图片时,逐张调用:
```bash
for img in {image_list}; do
  meitu image-cutout --image "$img" --json --download-dir {output_dir}
done
```

注意:`image-cutout` 每次只处理一张图,不支持 `--image_list`。

**结果检查**

解析 `--json` 输出:
- `ok: true` → 成功,`downloaded_files[0].saved_path` 为本地已下载的结果 PNG(透明背景);若未使用 `--download-dir`,则取 `media_urls[0]`
- `ok: false` → 检查 `code` 和 `hint`

**错误降级**

| 级别 | 动作 | 说明 |
|------|------|------|
| L1 | 切换 model_type | 自动检测失败时,依次尝试 0→1→2 |
| L2 | 检查图片格式/大小 | 确保图片可访问且非损坏 |
| L3 | 停止并报错 | 2 次连续失败后,输出 `code` + `hint` |

特殊错误:
- `ORDER_REQUIRED` → 提示用户充值,展示 `action_url`
- `CREDENTIALS_MISSING` → 提示配置 AK/SK

### Deliver

直接使用 Preflight 解析的 output_dir。

`mv {file} {output_dir}/{date}_{name}_cutout.png`

## Output

- **格式**: PNG(透明背景)
- **命名**: `{YYYY-MM-DD}_{descriptive-name}_cutout.png`
  - 例: `2026-03-23_product-photo_cutout.png`
- **位置**: 由 Deliver 步骤决定(项目 → `./output/`,一次性 → `$VISUAL/output/meitu-cutout/`)
