图片输入方式：
从以下三种方式中选择一种，

1. 使用公开 URL - 适用于可公开访问的图片
2. 使用本地文件 - 适用于本地开发和测试
3. 使用 Base64 编码 - 适用于私有图片或需要加密传输的场景
"""

# [方式 1] 使用可公开访问的图片 URL
# 示例：使用公开图片 URL
img_url = "https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250925/wpimhv/rap.png"

# [方式 2] 使用本地文件（支持绝对路径和相对路径）
# 格式要求：file:// + 文件路径
# 示例（绝对路径）：
# img_url = "file://" + "/path/to/your/img.png"    # Linux/macOS
# img_url = "file://" + "/C:/path/to/your/img.png"  # Windows
# 示例（相对路径）：
# img_url = "file://" + "./img.png"                # 相对于当前可执行文件的路径

# [方式 3] 使用 Base64 编码的图片
# img_url = encode_file("./img.png")

# 设置音频 URL
audio_url = "https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250925/ozwpvi/rap.mp3"
