Métodos de entrada de imagen:
Se proporcionan los tres métodos siguientes; elija uno de ellos:

1. Usar una URL pública - para imágenes ya accesibles públicamente
2. Usar un archivo local - para desarrollo y pruebas locales
3. Usar codificación Base64 - para imágenes privadas o escenarios que requieren transmisión cifrada

# [Método 2] Usar un archivo local (se admiten rutas absolutas y relativas)
# Requisito de formato: file:// + ruta del archivo
# Ejemplo (ruta absoluta):
# mask_image_url = "file://" + "/path/to/your/mask_image.png"     # Linux/macOS
# base_image_url = "file://" + "C:/path/to/your/base_image.jpeg"  # Windows
# Ejemplo (ruta relativa):
# mask_image_url = "file://" + "./mask_image.png"                 # Use la ruta real
# base_image_url = "file://" + "./base_image.jpeg"                # Use la ruta real

# [Método 3] Usar una imagen codificada en Base64
# mask_image_url = encode_file("./mask_image.png")               # Use la ruta real
# base_image_url = encode_file("./base_image.jpeg")              # Use la ruta real
