Ghostscript:“无法恢复的错误:setpagedevice中的未定义文件名"

问题描述

我正在尝试使用ghostscript压缩pdf文件:

I'm trying to compress pdf files using ghostscript like this:

gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH  -sOutputfile=output.pdf input.pdf

我过去已经成功完成了此操作，但是由于某种原因，现在它不起作用了.我收到以下错误:

I've done this successfully in the past, but for some reason now it won't work. I get the following error:

GPL Ghostscript 9.15 (2014-09-22)
Copyright (C) 2014 Artifex Software, Inc.  All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
**** Unable to open the initial device, quitting.
Unrecoverable error: undefinedfilename in setpagedevice
Operand stack:
    true  --nostringval--  --nostringval--  --nostringval--  --nostringval--  --nostringval--  --nostringval--  --nostringval--  --nostringval--

[我将-SOutputFile的错字固定为-sOutputFile，以避免出现这种红色鲱鱼. (但这就是某些评论/答案所指的内容.)

推荐答案

这对我有用...

gs \
   -sDEVICE=pdfwrite \
   -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer \
   -dNOPAUSE \
   -dQUIET \
   -dBATCH \
   -sOutputFile=output.pdf \
    input.pdf

要明确说明(并再次重申KenS在评论中写的内容):

To spell it out explicitly (and to re-iterate what KenS wrote in his comment):

1. -SOutputFile=...不起作用
2. -sOutputFile=...是正确的语法. (Ghostscript命令行参数区分大小写！)

1. -SOutputFile=... does NOT work
2. -sOutputFile=... is the correct syntax. (Ghostscript command line parameters are case sensitive!)

此外，在最新版本的Ghostscript中，您现在可以使用-o output.pdf而不是长版本. -o ...也会自动隐式设置-dBATCH -dNOPAUSE参数.因此，编写此命令的最短方法是:

Also, with recent versions of Ghostscript, you can now use -o output.pdf instead of the long version. -o ... also automatically and implicitely sets the -dBATCH -dNOPAUSE parameters. So the shortest way to write this command is:

gs                          \
   -sDEVICE=pdfwrite        \
   -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer   \
   -q                       \
   -o output.pdf            \
    input.pdf
