书籍封面最佳实践

类型惯例

遵循既定的类型视觉语言，满足读者预期：

• 惊悚类读者期待黑暗、紧张的图像
• 爱情类读者喜欢动人、亲密的场景
• 科幻类读者期待未来感或宇宙元素
• 商业类读者偏好简洁、专业的设计

预留标题空间

务必明确指定文字放置区域：

• 为标题预留顶部三分之一的空间
• 在底部留出作者姓名的位置
• 印刷版需考虑书脊区域
• 避免将重要图像放在文字覆盖的区域

缩略图测试

针对多种查看尺寸进行设计：

• 封面在较小尺寸下（在线商店中）也必须易于识别
• 使用高对比度和醒目的元素
• 避免使用缩略图尺寸下会消失的精细细节
• 在不同尺寸下测试文字的易读性

印刷版与数字版

考虑最终格式：

• 印刷版：考虑出血、书脊和封底
• 电子书：针对屏幕查看进行优化
• 有声书：采用方形格式，并确保在极小尺寸下也适用

提示词技巧

情绪与氛围

具体描述情绪基调：

• “阴森紧张”与“黑暗神秘”
• “温暖浪漫”与“热情奔放”
• “奇趣活泼”与“魔幻迷人”

排版空间

务必提及文字放置需求：

• “在顶部三分之一处留出清晰区域，用于放置标题文字”
• “在上方区域留出负空间，用于放置大号字体”
• “构图应适合放置居中的标题和副标题”

类型预期

参考特定类型的元素：

• “具有现代感的经典惊悚风格”
• “当代爱情小说封面风格”
• “沿袭主要奇幻出版商传统的史诗奇幻风格”

调色板

指定适合类型的颜色：

• 惊悚：深蓝、黑色、深红
• 爱情：暖金色、粉色、柔和的浅色调
• 科幻：冷蓝色、紫色、霓虹点缀
• 自助：简洁的白色、鼓舞人心的色彩、极简调色板

模式选择

Max 模式

以下情况使用 "mode": "max"：

• 最终版书籍封面
• 专业出版品质
• 复杂细致的场景
• 可直接印刷的作品

Eco 模式

以下情况使用 "mode": "eco"：

• 快速探索概念
• 测试不同方向
• 迭代草稿
• 注重预算的项目

多轮对话

使用 session_id 在多个请求之间保持上下文：

# Initial cover concept
curl -X POST "https://eachsense-agent.core.eachlabs.run/v1/chat/completions" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create a book cover for a cozy mystery novel set in a small bookshop. Show a charming bookstore exterior at dusk with warm light glowing from windows, a cat sitting in the doorway, autumn leaves scattered on the cobblestone."}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "cozy-mystery-cover",
    "mode": "max"
  }'

# Request variation
curl -X POST "https://eachsense-agent.core.eachlabs.run/v1/chat/completions" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create another version with the same bookshop but from an interior perspective, looking out through the window at the evening street. Keep the cozy, inviting atmosphere and the cat somewhere in the scene."}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "cozy-mystery-cover",
    "mode": "max"
  }'

错误处理

在实现中处理常见错误：

# Check for API key
if [ -z "$EACHLABS_API_KEY" ]; then
  echo "Error: EACHLABS_API_KEY environment variable not set"
  exit 1
fi

# Make request with error handling
response=$(curl -s -w "\n%{http_code}" -X POST "https://eachsense-agent.core.eachlabs.run/v1/chat/completions" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create a minimalist book cover with abstract geometric shapes in blue and gold."}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max"
  }')

http_code=$(echo "$response" | tail -n1)
body=$(echo "$response" | sed '$d')

if [ "$http_code" -ne 200 ]; then
  echo "Error: API returned status $http_code"
  echo "$body"
  exit 1
fi

echo "$body"
