All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

# 護照照片 {#passport-photo}
|
||
|
||
AI 驅動的護照與證件照產生器。採用兩階段工作流程:分析(臉部偵測 + 背景移除),接著產生(裁切、調整大小並拼貼以供列印)。
|
||
|
||
## API 端點 {#api-endpoints}
|
||
|
||
此工具使用兩階段流程,分析與產生各自使用獨立的端點。
|
||
|
||
**模型套件包:** `background-removal` 與 `face-detection`
|
||
|
||
---
|
||
|
||
### 階段 1:分析 {#phase-1-analyze}
|
||
|
||
`POST /api/v1/tools/image/passport-photo/analyze`
|
||
|
||
偵測臉部特徵點並移除背景。傳回特徵點資料與預覽,供前端顯示裁切預覽。
|
||
|
||
#### 參數 {#parameters}
|
||
|
||
| 參數 | 類型 | 必填 | 預設值 | 說明 |
|
||
|-----------|------|----------|---------|-------------|
|
||
| file | file | 是 | - | 圖片檔案(multipart) |
|
||
| clientJobId | string | 否 | - | 選用的作業 ID,用於透過 SSE 追蹤進度 |
|
||
|
||
#### 範例請求 {#example-request}
|
||
|
||
```bash
|
||
curl -X POST http://localhost:1349/api/v1/tools/image/passport-photo/analyze \
|
||
-F "file=@headshot.jpg"
|
||
```
|
||
|
||
#### 回應(200 OK) {#response-200-ok}
|
||
|
||
```json
|
||

```
|
||
|
||
#### 進度(SSE,選用) {#progress-sse-optional}
|
||
|
||
若提供 `clientJobId`,則會串流傳送進度(臉部偵測為 0-30%,背景移除為 30-95%)。
|
||
|

|
||
|
||
```json
|
||
{
|

### 基礎路由 {#base-route}
|
||
|
||
`POST /api/v1/tools/image/passport-photo`
|
||
|
||
傳回引導以使用正確的子端點。
|
||
|
||
```json
|
||
{
|
||
"error": "Use /api/v1/tools/image/passport-photo/analyze or /generate"
|
||
}
|
||
```
|
||
|
||
## 注意事項 {#notes}
|
||
|
||
- 需要安裝 `background-removal` 與 `face-detection` 模型套件包。
|
||
- 階段 1 執行 AI(臉部特徵點 + 背景移除)並快取結果。階段 2 為純 Sharp 圖片處理(快速,不需 AI)。
|
||
- 特徵點以正規化座標傳回(0-1 範圍,相對於圖片尺寸)。
|
||
- 分析回應中的 `preview` 欄位為 base64 編碼的 PNG(最大寬度 800px),供快速顯示。
|
||
- 國家規格包含依據官方護照照片要求的文件尺寸、頭部高度比例與眼線定位。
|
||
- `printLayout` 選項會在 4x6\" 或 A4 紙上產生拼貼版面,照片之間有 2mm 的間距。
|
||
- 設定 `maxFileSizeKb` 時,輸出會反覆壓縮以符合大小限制。
