Watermark & Resize

😫 The Pain Point

Shopee/Lazada requires all images to be 1:1 Square. And you want your shop logo in the corner to prevent theft. Doing 2 steps (Crop + Stamp) for 100 products = 200 actions.

🚀 Agentic Solution

The Pipeline: Chains multiple image operations into one command.

Key Features:

• Padding: If image is rectangular, it adds white padding to make it square (instead of cropping content).
• Positioning: Logo is placed 20px from the bottom-right corner automatically.

⚔️ Phase 1: Commander (Quick Fix)

For a new product launch.

Prompt:

“I have a folder of product photos. 1. Resize them to fit within 1000x1000 px, adding white padding to make them perfect squares. 2. Paste logo.png in the bottom-right corner. Save to ‘Processed’.”

Result: Shop-ready photos.

🏗️ Phase 2: Architect (Permanent Tool)

For Shop Owners.

3.  **Deliverables:** `shop_images.py`, `run.bat` (Windows), `run.sh` (Mac).

🧠 Prompt Decoding

• Square Padding: This is E-commerce 101. If you simple force resize a 4:3 photo to 1:1, it stretches. The “Padding” logic preserves the aspect ratio while meeting platform requirements.
