SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

このスキルは、テキストの説明からドット絵・ピクセルアートを作成する作業を自動化します。高品質なイラストを生成し、それをドット絵風に再生成し、背景を真緑色に統一して最終的にピクセルアートへ変換する一連の手順を提供します。

Core Features & Use Cases

3ステップのドット絵生成パイプライン: Step 1 は高品質イラストの生成、Step 2 でドット絵風の再生成、Step 2.5 で背景の単一色化、Step 3 で true pixel art へ変換。
GBA向け出力を想定した解像度管理: 指定された解像度に合わせてピクセルアートの最適化を行う。
再利用性と柔軟性: プロンプトを全文ファイルとして活用する設定があり、背景やアスペクト比の指定にも対応。

Quick Start

Step 1: 高品質なイラストを生成して /tmp/pixelart_step1.png に保存する。Step 2: Step 1 の出力を参照画像としてドット絵風に再生成し、/tmp/pixelart_step2.png に保存する。Step 2.5: /tmp/pixelart_step2.png をグリーン背景 #00FF00 に統一して /tmp/pixelart_step2_unified.png に保存する。Step 3: proper-pixel-art を用いてダウンサンプリング＋量子化を実行し、最終出力を所定のパスに保存する。出力を目視確認して完了。

FAQPage Schema

How do I generate pixel art from text prompts for game assets?▼

You can generate pixel art from text prompts through a three-step pipeline that creates a high-quality illustration, regenerates it in a pixel-art style, and downsamples it into true pixel art.

Can I create GBA-sized character sprites using an automated pixel art pipeline?▼

Yes, the pixel art pipeline supports GBA-sized outputs and character sprites by managing resolution and applying targeted downsampling plus quantization to match your specified dimensions.

What is the process for converting a high-quality illustration into true pixel art?▼

The conversion process first generates a reference illustration, regenerates it as pixel-art style, unifies the background to a solid color, and applies proper-pixel-art downsampling for the final output.

How does background unification help in automated pixel art conversion?▼

Background unification replaces the original background with a solid green color before the final pixel art conversion, allowing the proper-pixel-art step to cleanly isolate and process the subject.

Do I need ImageMagick to manipulate images for pixel art generation?▼

Yes, the pipeline uses ImageMagick for image manipulation tasks such as unifying the background color before applying the final proper-pixel-art conversion parameters.

What are the limitations of generating pixel art from descriptive prompts?▼

The pipeline requires explicit prompt transfers and intermediate file saves at each step, meaning you must verify each visual output sequentially to ensure the final pixel art matches your intended retro-style design.
