"""原子工具：渲染 PPT
|
||
|
|
|
||
|
|
从 Job JSON 渲染 PPT 文件。支持 template 和 composer 两种模式。
|
||
|
|
|
||
|
|
用法:
|
||
|
|
python render_ppt.py job.json
|
||
|
|
python render_ppt.py job.json --data-dir data/ # 覆盖 CSV 路径前缀
|
||
|
|
|
||
|
|
输出 (stdout):
|
||
|
|
{"status": "ok", "output": "<path>"}
|
||
|
|
{"status": "error", "message": "..."}
|
||
|
