1. Gunakan URL gambar publik - cocok untuk gambar yang dapat diakses publik.
2. Gunakan file lokal - cocok untuk pengembangan dan pengujian lokal.
3. Gunakan pengkodean Base64 - cocok untuk gambar pribadi atau skenario yang memerlukan transmisi terenkripsi.

# Contoh (jalur mutlak):
# mask_image_url = "file://" + "/path/to/your/mask_image.png"     # Linux/macOS

# Contoh (jalur relatif):
# mask_image_url = "file://" + "./mask_image.png"                 # Berdasarkan jalur aktual
# base_image_url = "file://" + "./base_image.jpeg"                # Berdasarkan jalur aktual

# [Metode 3] Gunakan gambar yang dikodekan Base64
