图像输入方式说明：
以下提供了三种图片输入方式，三选一即可

1. 使用公网URL - 适合已有公开可访问的图片
2. 使用本地文件 - 适合本地开发测试
3. 使用Base64编码 - 适合私有图片或需要加密传输的场景
"""

# 【方式一】使用公网图片 URL

# 【方式二】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）：
# mask_image_url = "file://" + "/path/to/your/mask_image.png"     # Linux/macOS
# base_image_url = "file://" + "C:/path/to/your/base_image.jpeg"  # Windows
# 示例（相对路径）：
# mask_image_url = "file://" + "./mask_image.png"                 # 以实际路径为准
# base_image_url = "file://" + "./base_image.jpeg"                # 以实际路径为准

# 【方式三】使用Base64编码的图片
# mask_image_url = encode_file("./mask_image.png")               # 以实际路径为准
# base_image_url = encode_file("./base_image.jpeg")              # 以实际路径为准
