我有一个带有pdfInfo的pdf:

I have a pdf with such pdfInfo:

跟随此线程，我尝试调整大小并添加使用以下命令的bleeBox:

following this thread I try to resize and add a bleeBox with this command:

gs -o output.pdf \
   -sDEVICE=pdfwrite \
   -r72 \
   -dPDFA \
   -sProcessColorModel=DeviceCMYK \
   -dFIXEDMEDIA \
   -dDEVICEWIDTHPOINTS=667 \
   -dDEVICEHEIGHTPOINTS=913 \
   -c "[/ArtBox[36 36 631 877]" \
   -f book.pdf

我只得到了一个略大的pdf，带有正确的mediabox，但没有附加bleedbox ...我想念什么?

i only get a slightly bigger pdf with correct mediabox but no bleedbox attached... what Am I missing?

我不明白什么地方出了问题:命令，语法，或者如果我只是想使某些事情变得不可能 谢谢您的帮助！

I don't understand what is wrong: the command, the syntax or if I'm just trying to make something impossible thanks for any help!

推荐答案

首先，您在命令行中均未指定BleedBox.您确实提到了ArtBox，但这不是一回事.

Firstly, nowhere in your command line do you specify a BleedBox. You do mention an ArtBox but that's not the same thing.

其次，您不能只是将/ArtBox随意粘贴在PostScript流中并期望它可以执行任何操作.此"[/ArtBox [36 36 631 877]"甚至都不是有效的PostScript，因为您有不平衡的数组标记.

Secondly, you can't just arbitrarily stick a /ArtBox in the PostScript stream and expect it to do anything. This "[/ArtBox[36 36 631 877]" isn't even valid PostScript because you have unbalanced array marks.

您的命令行应改为

-c "[/ArtBox [36 36 631 877] /PAGES pdfmark" -f

除非您实际上确实想要BleedBox，否则必须将/ArtBox替换为/BleedBox.

Unless You actually do want a BleedBox in which case you will have to replace the /ArtBox with /BleedBox.
