把目标目录里所有 png/jpg/jpeg 用本机真 Photoshop 导出为统一规格的 JPG,再清理元数据中暴露 PNG 来源的痕迹。一条命令跑完两步,原文件保留不动。
目标是让封面带上真实可信的 Photoshop 元数据(Software=Adobe Photoshop、sRGB ICC、质量 12 Progressive、内嵌缩略图等),脚本伪造的元数据经不起深度核对。所以必须走真 Photoshop 的 Save As 路径,元数据由 PS 自己写。导出后再把 XMP History 里的 created → converted → saved(含 from image/png to image/jpeg)改写成干净的 created → saved,保留各自真实时间戳与 instanceID,时间线自洽。
${CLAUDE_PLUGIN_ROOT}/scripts/psjpg.sh <源目录> [输出目录] [质量 1-12]| 参数 | 默认 |
|---|---|
| 源目录 | 必填 |
| 输出目录 | <源目录>_psjpg(单独目录,原图不动) |
| 质量 | 12(PS 最高档) |
# 只清理元数据痕迹(不重新导出),可对目录或指定文件

/Applications/ 下的 Adobe Photoshop*,兼容 2026/2025/CC 多版本,不写死版本)。brew install exiftool),清理痕迹用;缺失时脚本会提前报错。softwareAgent 从导出 JPG 的 IFD0:Software 动态读取真实版本,不写死版本号。foo.png 和 foo.jpeg,导出的 foo.jpg 会互相覆盖(脚本会提示差额)。OriginalDocumentID、SlicesGroupName 是真实 PS 文件本就有的字段,不暴露 PNG 来源,保留更自然,脚本不动它们。| 文件 | 作用 |
|---|---|
psjpg.sh | 入口:导出 + 清理一条龙 |
ps_export.jsx | Photoshop ExtendScript,真 PS 导出 JPG;参数从 /tmp/cyxj_psjpg_cfg.txt 读 |
clean_metadata.sh | exiftool 清理 XMP History,可独立调用 |
