bozo-prompt-json — Ideogram 4.0 结构化 JSON 提示词生成器

将用户的自然语言描述或参考图片转换为 Ideogram 4.0 标准格式的结构化 JSON 提示词。

核心能力

工作流程

第一步：确定输入类型

输入 A — 纯文字描述：用户直接用自然语言描述想要的图像。

输入 B — 参考图片：用户提供一张图片作为参考（可能附带简短说明）。此时必须使用 VLM 模型分析图片内容，提取视觉信息后生成 JSON。

输入 C — 文字 + 参考图片：用户同时提供描述和参考图。以参考图的视觉信息为基础，结合用户文字进行增强和调整。

第二步：分析并构建 JSON

根据输入内容，按照以下 JSON Schema 构建输出：

{
  "high_level_description": "整体画面的一句话概括，包含主体、氛围、风格基调",
  "style_description": {
    "aesthetics": "美学风格关键词",
    "lighting": "光照描述",
    "photo": "摄影参数/胶片风格（如果是照片）",
    "medium": "媒介类型：Photograph / Illustration / Digital art 等",
    "art_style": "具体艺术风格",
    "color_palette": ["#HEX1", "#HEX2"]
  },
  "compositional_deconstruction": {
    "background": "背景的详细描述，包括环境、氛围、光影效果",
    "elements": [
      {
        "type": "obj | text",
        "bbox": [y_min, x_min, y_max, x_max],
        "desc": "对象/元素的详细视觉描述",
        "text": "仅 type=text 时填写，要渲染的文字内容"
      }
    ]
  }
}

第三步：输出规则

1. 始终输出完整 JSON，不可省略任何顶层字段
2. color_palette 是可选字段，但推荐在需要精确色彩控制时提供（每图最多 16 色）
3. bbox 是可选字段，但推荐对关键元素提供精确定位
4. type 字段：普通物体用 "obj"，需要在图中渲染文字用 "text"
5. text 元素必须同时包含 text（原始文字）和 desc（样式描述）两个字段
6. 坐标系：[y_min, x_min, y_max, x_max]，原点在左上角，范围 0–1000
7. 元素描述要具体到可被模型理解的程度——材质、颜色、光影、位置关系都要写清楚

各字段撰写指南

high_level_description

一句话总览。包含：

• 主体内容（什么场景/物体）
• 视角和构图（close-up / wide shot / top-down 等）
• 整体氛围和情绪
• 关键风格标签

好示例：

> "A cinematic 35mm film photograph of a lone wooden sailboat on a glassy lake at sunset, the boat on a right-third vertical with the horizon at the lower third, in a cool muted blue palette."

差示例：

> "一艘船在湖上" （太模糊，缺少风格、构图、氛围信息）

style_description

各子字段不是都必须填写，根据实际需求选择：

compositional_deconstruction — background

背景描述要覆盖：

• 环境/空间设定
• 光照条件和大方向
• 整体色调和质感
• 大气效果（雾气、景深等）

compositional_deconstruction — elements

每个元素遵循以下原则：

1. 从大到小排列：先主要物体，再次要物体，最后前景装饰
2. 描述要有层次：形状 → 颜色 → 材质 → 光影 → 与其他元素的关系
3. 数量适中：通常 5–15 个元素，过多会降低每个元素的权重；过少则信息不足
4. text 元素特殊处理：
• text 字段：实际要显示的文字，\n 表示换行
• desc 字段：字体、大小、颜色、排版方式的视觉描述
• bbox：文字区域的定位框

输入处理策略

处理纯文字输入

直接将用户描述拆解为 JSON 的各个字段。如果用户描述比较模糊，需要合理推断并补充细节。例如：

用户输入："一只猫坐在窗台上看书"

推断补充：

• 推断为温馨插画风格（而非超写实照片）
• 补充窗户的光影效果
• 补充书本的具体样子
• 补充猫的姿态细节

处理参考图片输入

使用 VLM 分析图片后提取：

1. 整体构图和视角
2. 主要物体及其位置关系
3. 色彩分布（提取主色调转为 HEX）
4. 光照方向和强度
5. 材质和纹理特征
6. 如果有文字：字体、大小、颜色、位置

然后将以上信息重组为标准 JSON 格式。

处理文字 + 图片

以图片分析结果为基础骨架，用户文字作为修改指令覆盖或增强对应部分。优先级：用户明确指定 > 图片分析 > 合理推断。

示例 1：风景照片

输入："黄昏时分的海边灯塔，暖色调，电影感"

{
  "high_level_description": "A cinematic wide-angle photograph of a solitary lighthouse standing on a rocky coastline at golden hour, warm amber light bathing the stone tower, shot on Kodak Portra 400 with deep foreground rocks and a misty sea stretching to the horizon.",
  "style_description": {

注意事项

1. 不要过度填充：如果某个字段没有实质内容，宁可省略也不要凑数。比如非照片类图像不需要 photo 字段。
2. 元素描述的质量 > 数量：3 个精心描述的元素比 10 个笼统描述效果好得多。
3. 保持一致性：high_level_description、background 和各 element 的 desc 在风格、色调、光照上要保持一致。
4. 利用调色板但不滥用：只在确实需要精确控制主色调时才提供 color_palette，让模型有合理的创作空间。
5. 边界框是建议性的：模型会尊重 bbox 但不保证像素级精确，用它来表达"大致在这个区域"的意图即可。
