工具使用说明--图像工具
- 创建图像工具
1.1 商店 --创建—图像工具选项卡下点击“+创建”按钮
1.2 依次填入信息，点击Create创建图片工具。
1.3 注意事项。
• 如果图片工具不存在，Ava或是白板里都是无法自行生成图片的。首次使用时需要创建或者订阅一个默认的“图片生成工具”，提示词为必填项，但我们不做限制，所以可以输入一个空格，然后启用“深度智能体”即可使用。
• 除了默认的图片生成工具。您也可以填写预定义的提示词来制作专有场景下的图片工具。
• 在Ava中用自然语言调用工具的指令应当尽量准确的指出您要使用的工具名称。例如：请使用xx图片工具，根据以下内容生成1张图片。
• 已经选择了预定义图片工具的生成场景，请输入生成指令时，用户提示词不要和预定义的图片工具冲突。
以下是一些预定义图片工具的提示词示例供参考：
Nano banana适用图片的提示词示例1（自然语言），适用于一般性创作场景：

Nano banana适用图片的提示词示例2（产品模型JSON格式），适用于需要精准控图的场景：
请你根据用户输入的信息自动补全以下提示词然后输出图片，如果信息不足请靠推理补全，要求：

Maintain high realism, no text, no logos added, no extra props. 8K, HDR, clean composition, balanced negative space.”"
