Why pack_product.py Renders Both a 1280×720 Cover and a 600×600 Thumbnail

说明与用途

pack_product.py 自动从单一源生成 1280×720 封面和 600×600 缩略图，保证品牌一致性并节省时间。

问题

Manual cover creation for each product leads to inconsistent, blurry, and time‑consuming results.

结果

Automated rendering reduced cover creation time from ~10 minutes to seconds, ensured consistent branding across ~1,700 assets, and prevented edge clipping in marketplace grids.

工作流

• Create a source template image with layout, title, subtitle, and price.
• Run python pack_product.py my-product "My Product" "A short subtitle" 9 to generate cover and thumbnail.
• Script outputs my-product-cover.jpg and my-product-thumb.jpg into the _system folder.
• Use these images in the product zip for marketplace upload.
• Repeat for each new or updated product without manual editing.

证据

I wrote pack_product.py to render both a 1280×720 cover and a 600×600 thumbnail from the same source, in the same run, every time.

来源

When I update a product, the script regenerates both images identically, so nothing drifts.

This whole pipeline runs on 1 vCPU and 2 GB RAM with no GPU.

I never touch an image editor for packaging anymore.
