如何通过 pdftk 管道生成 pdf 输出以删除注释？

Question

我想通过 pdftk 传输 pdf 生成输出以删除注释。

我怎样才能合并一个有效的 AppleScript 行的这个现有部分：

do shell script "/usr/local/bin/$pdf-generating-app --page-size=A4 --page-margin=5mm " & (quoted form of POSIX path of filename) & " -o " & (quoted form of POSIX path of outputFilename)

并根据 by Farid Cheraghi?

通过 pdftk 删除注释

sh pdftk in.pdf output - uncompress | sed '/^\/Annots/d' | pdftk - output out.pdf compress

Answer 1

如果是 YeLogic prince，您可以使用连字符 (-) 使其输出到 stdout，然后将其通过管道传输到 pdftk :

/usr/local/bin/prince --page-size=A4 --page-margin=5mm <your filename> -o - | \
pdftk - output - uncompress | sed '/^\/Annots/d' | pdftk - output out.pdf compress

对于 AppleScript，应该是：

do shell script "/usr/local/bin/prince --page-size=A4 --page-margin=5mm " & (quoted form of POSIX path of filename) & " -o - | pdftk - output - uncompress | sed '/^\/Annots/d' | pdftk - output " & (quoted form of POSIX path of outputFilename) & " compress"

总之，建议你直接用prince去除水印，通过CSS属性应该可以。

这是最终版本，主要由 Zilog80 编译，对我有用：

do shell script "/usr/local/bin/$pdf-generating-app --page-size=A4 --page-margin=5mm " & (quoted form of POSIX path of filename) & " -o - | /usr/local/bin/pdftk - output - uncompress | sed '/^\/Annots/d' | /usr/local/bin/pdftk - output " & (quoted form of POSIX path of outputFilename) & " compress"
