  --width 1024 \
  --height 1024

Image generate (image-to-image)

Local image:

python3 {baseDir}/scripts/image_generate.py \
  --prompt "改成赛博朋克风格" \
  --image /path/to/reference.png \
  --width 1024 \
  --height 1024

URL image:

python3 {baseDir}/scripts/image_generate.py \

Behavior

• 本地参考图：先上传 OSS，再传给 DashScope
• URL 参考图：直接透传给 DashScope
• 默认一次生成 1 张图
• 成功后 stdout 打印保存路径
• 若文件名已存在，自动重命名
• 失败时输出错误信息并返回非 0 退出码
