SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires google-genai, Pillow, python-dotenv, numpy, scipy, requests, and includes scripts (resource) components.

What problem does it solve?

Generate high-quality LINE/WeChat style chibi sticker sheets from a character reference image, including white-background sheets, transparent alpha outputs, and 32 individual cell PNGs for easy distribution.

Core Features & Use Cases

  • Generate a 4×8 sticker sheet from a single character reference using Gemini image-to-image prompts.
  • Output sheet_white.png, sheet_transparent.png, and 32 cells (512×512 each) for flexible posting and editing.
  • Use a two-call workflow to maximize per-cell resolution and ensure consistent art style across all cells.

Quick Start

Provide a character reference image and a 32-expression prompt to generate and slice a 4×8 chibi sticker sheet into sheet_white.png, sheet_transparent.png, and cells/*.png.

Frequently Asked Questions about chibi-sticker-sheet

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a chibi sticker sheet from a character reference image?▼

To generate a chibi sticker sheet, provide a character reference image and a 32-expression prompt. The workflow uses Gemini image-to-image generation to create a 4x8 sheet, then slices it into individual 512x512 PNG cells.

What image formats are exported for the LINE and WeChat chibi stickers?▼

The sticker generation exports sheet_white.png for white backgrounds, sheet_transparent.png for alpha backgrounds, and 32 individual 512x512 cell PNGs. These formats ensure flexible posting and editing across platforms.

Do I need a specific API key to use Gemini image-to-image prompts for sticker sheets?▼

Yes, you need authentication keys for Gemini or Vertex AI. The tooling accepts GOOGLE_AI_STUDIO_API_KEY, GEMINI_API_KEY, GOOGLE_API_KEY, or VERTEX credentials to authorize the image-to-image generation calls.

Why does the sticker sheet workflow use a two-call generation process?▼

The two-call workflow maximizes per-cell resolution and ensures a consistent art style across all 32 stickers. By splitting the generation process, it preserves quality when slicing the 4x8 sheet into individual images.

How does the tool create transparent backgrounds for the chibi sticker PNGs?▼

The tooling uses Python-based Pillow processing with a flood-fill alpha keying method to generate sheet_transparent.png. This technique cleanly removes backgrounds from the generated chibi sticker images.

What Python dependencies are required to slice chibi sticker sheets into individual cells?▼

Slicing sticker sheets requires the Pillow imaging library, along with numpy and scipy for processing. These Python dependencies handle the flood-fill alpha keying and image cropping for the 32 cell outputs.
