# 在本機建立有序圖片 PDF

Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/build-image-pdf

`sosoapi_build_image_pdf`

按 source_asset_ids 次序，從一至二十張有權存取嘅 Workspace 圖片，在本機建立 PDF 同精確 JPEG 頁面預覽。完整放入圖片，唔會裁切；支援 Unicode 標題同正方形、直向、橫向頁面，PDF 最多 50 MiB。只提供本機檔案；唔會冒充圖片素材或發布到 LinkedIn。

## Profiles 及連接方式

Profiles: core, full

Transports: stdio

Profile 只影響工具可見性，唔會授權。HTTP 冇本機檔案上傳。SOSOAPI_OUTPUT_SCHEMAS=1 會宣告輸出 schema；兩種模式都會回傳 structured results。

## 權限及改動

MCP annotations 只係發現提示，唔係存取控制保證；仍然有實際登入、角色、資源及能力檢查。

## 結構化輸出

此 schema 描述成功工具結果嘅 structuredContent。MCP envelope 亦包括 content，失敗可能設定 isError；唔好將文字收據或接受請求當成平台終態。權限及重試規則見對應 API 操作。

```json

  "properties": {
    "stage": {
      "type": "string",
      "enum": [

## 工具呼叫範例

以下虛構值已按 contract 驗證，唔係真實帳戶 ID、憑證或發佈紀錄。請用已授權範圍回傳嘅 ID、已準備好嘅素材及已審核排程取代，寫入前核對平台資格。此頁唔會呼叫 API。

```json
{
  "name": "sosoapi_build_image_pdf",
  "arguments": {
    "workspace_id": "11111111-1111-4111-8111-111111111111",
    "source_asset_ids": [
      42,
      43
    ],
    "title": "圖片 / Images",
    "preset": "portrait"
  }
}
```
