基于完整人偶 + AI 图像编辑生成透明底服装/部件的操作指南

本文档记录经过实测验证的生成方法、参数模板和 prompt 编写技巧。

适用于换装系统的服装候选图快速生成。

1. 核心方法将完整人偶图作为 edit_image 的输入参考，prompt 描述目标服装，设置 transparent=true，直接输出透明底的服装/角色图。完整人偶图（原始立绘）

↓ edit_image(transparent=true)

透明底服装/角色图

↓ 用户挑选 + 手动微调

最终服装图层

优势：

无需预处理底图（不需要色键填充、不需要裁剪）
无需后处理提取（不需要 chroma key、不需要 alpha mask）
一次调用即可出结果，适合快速迭代

2. 调用参数模板python

复制edit_image(

image = "人偶模板.png", # 完整人偶图（带体型参考）

prompt = "服装描述...", # 见第 4 节 prompt 编写指南

name = "输出文件名",

aspect_ratio = "2:3", # 竖版人物推荐

target_size = "1024", # 或具体尺寸如 "570x903"

transparent = True, # 🔴 必须！输出透明底

)

参数说明参数值说明image人偶图路径完整人偶立绘，AI 以此为体型参考prompt英文描述服装风格、颜色、材质、细节（详见第 4 节）aspect_ratio"2:3"竖版全身人物最佳比例target_size"1024"输出尺寸，AI 按此和 aspect_ratio 计算实际分辨率transparenttrue必须设置，否则输出白色背景已知特性

尺寸偏差：edit_image 输出尺寸可能与 target_size 不完全一致（实测宽度偏差约 +6.3%，如请求 570 返回 606），如需精确尺寸需后期 resize
输出内容：AI 会生成包含头发、脸部、身体的完整角色图（不是纯服装图层），服装穿在角色身上

3. 实测成功案例（4 张）以下 4 张图均使用同一人偶输入，效果良好，可作为 prompt 参考模板。共同参数：

输入图：人偶_mannequin_v4_20260427091300.png（完整人偶立绘）
aspect_ratio: "2:3"
target_size: "1024"
transparent: true

4. Prompt 编写指南4.1 有效的 prompt 结构[全身/角色描述] + [服装类型+颜色+材质+细节] + [保持参考图的体型/脸型/发型] + [画风] + [透明背景强调(可选)]

4.2 关键要素要素作用示例全身描述确保输出完整角色“Full body character design”, “Full body visible from head to feet”服装细节精确控制衣服样式“deep red qipao with gold floral embroidery, high mandarin collar, side slit”保持参考维持人偶体型一致性“same face, same hair, same body proportions as the reference”画风统一画面风格“clean anime illustration style, soft cel-shading”透明背景增强透明效果（可选）“CHARACTER ON TRANSPARENT BACKGROUND”transparent=true 参数本身就确保透明底，prompt 中加透明背景描述是额外保险，不加也可以。4.3 Prompt 精度分级阶段精度要求说明探索阶段低 — 简述风格即可快速试验多种方向，挑选最佳定制阶段中 — 描述风格+材质+主要装饰确保输出符合设计意图生产阶段高 — 精确到颜色、材质、装饰位置确保多次生成保持一致性4.4 中文 vs 英文实测中 4 张成功案例均使用英文 prompt。edit_image 对英文 prompt 的理解更稳定，建议优先使用英文。如用中文，建议结构："全身动漫角色设计，穿着[服装类型]。[颜色+材质+细节描述]。

保持与参考图相同的脸型、发型和身体比例。

干净的动漫插画风格，柔和的赛璐璐着色。"
