请求参数

参数	位置	类型	必填	说明	示例
`Content-Type`	Header	string	否	-	application/json
`Authorization`	Header	string	否	-	Bearer {{YOUR_API_KEY}}
`image`	JSON body	string	是	参考图片支持传入图片Base64编码或图片URL（确保可访问）	-
`up_expansion_ratio`	JSON body	number	是	向上扩充范围；基于原图高度的倍数而计算取值范围：[0,2]，新图片整体面积不得超过原图片3倍如原图高20，当前参数值为0.1，则：原图顶边距离新图顶边为20 x 0.1 = 2，区域内均为扩图范围	-
`down_expansion_ratio`	JSON body	number	是	向下扩充范围；基于原图高度的倍数而计算取值范围：[0,2]，新图片整体面积不得超过原图片3倍如原图高20，当前参数值为0.2，则：原图底边距离新图底边为20 x 0.2 = 4，区域内均为扩图范围	-
`left_expansion_ratio`	JSON body	number	是	向左扩充范围；基于原图宽度的倍数而计算取值范围：[0,2]，新图片整体面积不得超过原图片3倍如原图宽30，当前参数值为0.3，则：原图左边距离新图左边为30 x 0.3 = 9，区域内均为扩图范围	-
`right_expansion_ratio`	JSON body	number	是	向右扩充范围；基于原图宽度的倍数而计算取值范围：[0,2]，新图片整体面积不得超过原图片3倍如原图宽30，当前参数值为0.4，则：原图右边距离新图右边为30 x 0.4 = 12，区域内均为扩图范围	-
`prompt`	JSON body	string	否	正向文本提示词不能超过2500个字符	-
`n`	JSON body	integer	是	生成图片数量取值范围：[1,9]	-
`callback_url`	JSON body	string	否	-	-
`external_task_id`	JSON body	string	否	-	-
