# imgen - Azure OpenAI Image Generation CLI

## How to Run

imgen is NOT globally installed. Use one of these methods:

```bash
# 開発モード（ソースから直接実行、.envを自動読み込み）
npm run dev --prefix /Volumes/Data/dev/imgen -- <command>

# npx でソースから実行（.envは自動読み込みされない）
npx tsx /Volumes/Data/dev/imgen/src/index.ts <command>

# npm パッケージとして実行（npm install -g @nogataka/imgen 済みの場合）
imgen <command>
```

以下の例では `imgen` と表記するが、実際は上記いずれかの方法で実行すること。

## Quick Reference

```bash
imgen image gen "<prompt>" -q <quality> -s <size>    # 画像生成
imgen image edit <file> "<instruction>"               # 画像編集
imgen image explain <file> -l <lang>                  # 画像説明
```
