Photoshop JSX 证件照自动排版脚本

简介

使用 Photoshop JSX 脚本实现证件照自动排版打印，运行在 Photoshop 环境中，利用 Photoshop 提供的 JavaScript 自动化接口，实现从照片导入、尺寸调整、相纸设置到最终排版输出的完整流程。

Photoshop → 文件 → 脚本 → 浏览（选择脚本）→ 选择证件照 → 选择排版参数 → 生成

主要功能包括：

• 支持五寸、六寸、七寸相纸以及自定义尺寸
• 支持横向、纵向以及自动选择最佳排列方向
• 支持小一寸、一寸、大一寸、两寸等常用证件照规格
• 支持自定义照片尺寸
• 根据 DPI 自动计算像素尺寸，保证打印精度
• 自动计算一张相纸可容纳的照片数量
• 自动复制并排列照片
• 自动计算排版区域，实现照片整体居中
• 兼容 Photoshop 2020 及以上版本
