生成流程
步骤 1:设计文案
从用户输入提取:
- 主标题(最大字,1 行,核心概念/产品名/关键词)
- 副标题(次大字,1-2 行,核心洞察或 tagline)
- 标签(3 个功能/关键词标签,每个 2-4 字)
- 角标(左上小字,身份标签如 OPEN SOURCE / 论文解读 / 工具推荐)
- 底部(小字,3 个关键词用 · 分隔)
步骤 2:选择风格
- 如果用户指定了
--style,使用对应风格 - 否则根据内容自动选择:
- 论文/科研 → academic
- AI/编程/开源 → dark 或 morandi
- 工具/效率 → mint
- 个人感悟/发布 → sunset
- 观点/思考 → bw
步骤 3:生成 HTML
写入 /tmp/xhs-cover.html,遵循以下模板结构:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
* { margin: 0; padding: 0; box-sizing: border-box; }
body { width: 1080px; height: 1440px; overflow: hidden;
font-family: -apple-system, "PingFang SC", "Helvetica Neue", sans-serif; }
.canvas {
width: 1080px; height: 1440px;
background: {风格背景};
display: flex; flex-direction: column; justify-content: center;
padding: 60px 70px; gap: 36px; position: relative;
}
/* 角标 */
.badge { display: inline-flex; align-items: center; gap: 10px;
background: {主色 alpha 0.12}; border: 1.5px solid {主色 alpha 0.2};
border-radius: 10px; padding: 12px 24px; font-size: 28px;
font-weight: 700; color: {主色}; letter-spacing: 3px; width: fit-content; }
/* 主标题行 */
.title-row { display: flex; align-items: baseline; gap: 20px; white-space: nowrap; }
.title-main { font-size: 120-130px; font-weight: 900; color: {主色}; letter-spacing: -2px; }
.title-secondary { font-size: 110-120px; font-weight: 900; color: {副色}; }
/* 分隔线 */
.divider { width: 80px; height: 5px;
background: linear-gradient(90deg, {主色}, {副色});
border-radius: 3px; margin: 10px 0; }
/* 副标题 */
.tagline { font-size: 76-82px; font-weight: 800; color: {文字色};
letter-spacing: 8px; line-height: 1.4; }
.tagline .accent { color: {主色 或副色 淡化}; }
/* 标签 */
.chip { background: {标签背景}; border-radius: 14px; padding: 18px 32px;
font-size: 34px; font-weight: 700; letter-spacing: 2px; }
/* 底部 */
.footer { font-size: 30px; color: {文字色 淡化}; font-weight: 600; letter-spacing: 2px; }
</style>
</head>
<body>
<!-- 按上面的结构填充内容 -->
</body>
</html>
关键设计约束:
- 3:4 比例(1080×1440px)
- 文字占画面 70% 以上
- 主标题尽量一行放下(必要时缩小字号或拆行)
- 2-3 级文字层级:主标题 > 副标题 > 标签/底部
- 所有中文用 font-weight: 700-900
- 颜色最多用 3 种(主+副+辅助),不杂乱
步骤 4:截图
用 Playwright 截图保存:
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page(viewport={"width": 1080, "height": 1440})
page.goto("file:///tmp/xhs-cover.html")
page.wait_for_timeout(500)
page.screenshot(path="<输出路径>", full_page=False)
browser.close()
默认保存到 ~/Documents/Obsidian Vault/xhs/img/cover-{简短标识}.png。
步骤 5:展示
用 Read 工具展示生成的图片给用户,询问是否需要调整。
