Recraft Image Inpainting 节点允许你选择性地修改图像的特定区域，保持其余部分不变。通过提供图像、蒙版和文本提示词，可以精确地生成新内容填充指定区域。

​
参数说明

​
基本参数

参数类型默认值说明
image图像-需要修改的输入图像
mask蒙版-定义要修改区域的黑白蒙版
prompt字符串""描述要在蒙版区域生成的内容
n整数1生成结果的数量(1-6)
seed整数0随机种子值

​
可选参数

参数类型说明
recraft_styleRecraft Style设置生成内容的风格
negative_prompt字符串指定不希望在生成内容中出现的元素
recraft_controlsRecraft Controls附加控制参数(颜色等)

​
输出

输出类型说明
IMAGE图像修改后的图像结果
