Example Usage

```bash # 基础生成 node scripts/get_illust.js --prompt "1girl, red hair, blue eyes, maid outfit, smile" --output maid.png

# 高级设置 node scripts/get_illust.js \ --prompt "1girl, long silver hair, purple eyes, magical girl, cityscape at night" \ --negative "lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry, bad feet" \ --width 1024 \ --height 1536 \ --steps 28 \ --cfg-scale 6 \ --seed 42 \ --output magical_girl.png

# 使用不同模型 node scripts/get_illust.js \ --prompt "fantasy landscape, floating islands, waterfalls" \ --model "urn:air:sdxl:checkpoint:civitai:101055@128641" \ --output landscape.png

# 使用 LoRA node scripts/get_illust.js \ --prompt "1girl, red hair, blue eyes, maid outfit, smile" \ --lora "urn:air:sdxl:lora:civitai:162141@182559,0.8" \ --output maid_with_lora.png

# 使用多个 LoRA node scripts/get_illust.js \ --prompt "1girl, cat ears, cute smile, IncrsAhri, multiple tails" \ --lora "urn:air:sd1:lora:civitai:162141@182559,1.0" \ --lora "urn:air:sd1:lora:civitai:176425@198856,0.6" \ --output multi_lora.png ```
