使用示例

有了 Nano Banana，你可以用自然语言生成新图像，也可以编辑已有图像。只要描述想创建或修改的内容，goose 就会把它整理成详细提示词交给 Nano Banana。

图像创建示例

用描述从零生成图像：

• 「画一幅山间日落」
• 「为一家叫 Bean There 的咖啡店设计标志」
• 「画一条守护宝库的奇幻巨龙」

图像迭代示例

生成或编辑之后，可以继续微调：

• 「把天空改得更紫」
• 「在角落加一只猫」
• 「去掉文字」
• 「改成更卡通的风格」

goose 提示词

用 nano banana 画一幅奇幻冰法师在冰封工坊里雕冰雕的图像

goose 输出

桌面版

🎨 已用 nano-banana（Gemini 2.5 Flash Image）生成图像！

提示词：「一位奇幻冰法师在冰封工坊里雕冰雕。法师穿着带霜纹的飘逸长袍，双手散发蓝色魔法能量，正在塑造精致的冰雕。工坊里摆满美丽的冰晶作品：冰做的动物、水晶花和精细人偶。天花板垂着冰柱，石墙覆着霜，魔法蓝光照亮空间。雪花轻轻飘过。细致的奇幻艺术风格，带有魔法氛围。」

✨ 完成！ 这是你的奇幻冰法师图像。

画面效果很好，包含：

• 冰法师：一位戴兜帽的人物，身着深蓝色长袍，绣有精致的霜花和雪花，双手散发蓝色魔法光
• 冰雕：正在雕琢的独角兽、背景中的飞马、水晶玫瑰花束，以及小型骑士雕像
• 冰封工坊：像冰晶大教堂一样的空间，拱顶垂下戏剧性的冰柱，立柱覆霜，还有几何冰纹
• 魔法氛围：彩虹般的光线折射、飘落的雪粒，以及贯穿整个空间的空灵蓝光

图像已保存到： generated_imgs/generated-2025-12-04T04-15-47-907Z-3grhec.png

需要我对这张图做修改吗？我可以调整法师外观、增加雕塑、改变光线，或用 continue_editing 微调其他细节。
