使用PDFTK将PDF分成多页? [英] Split PDF by multiple pages using PDFTK?

问题描述

我很难用这个短语来表达问题，也找不到我想做的在线解决方案.

I am finding it hard to phrase this question and could not find an online solution for what I'm trying to do.

我知道如何使用以下脚本将大型PDF分为具有PDFTK的单个页面:

I know how to split a large PDF into single pages with PDFTK using the following script:

pdftk your_file.pdf burst output your_directory/page_%02d.pdf

但是现在我想按每个 other 页拆分PDF，以便每个新的PDF具有两(2)页(例如，第1 + 2页在一起，第3 + 4页在一起，第5 + 6等).

But now I want to split the PDF by every other page, so that each new PDF has TWO (2) pages (e.g. pages 1 + 2 together, pages 3 + 4 together, 5 + 6, etc.).

我知道Acrobat就像冠军一样，但是我需要可以从Powershell执行的东西.

I know that Acrobat does this like a champ, however I need something I can execute from Powershell.

我乐于接受其他选择/解决方法，例如将单页打印并在单次爆发后按两页合并.

I am open to alternatives/workarounds, like taking the single pages and combining them by two's after single bursting.

推荐答案

此PowerShell脚本将

This PowerShell script will

1. 使用pdftk获取页数
2. 逐步循环构建范围字符串
3. 使用范围将页面提取到新的pdf中，并将范围附加到基本名称(并存储在同一文件夹中).

更改前两个变量以适合您的环境.

Change the first two vars to fit your environment.

## Q:\Test\2017\05\06\Split-Pdf.ps1
$pdfPath = 'Q:\Test\2017\05\06\'
$pdfFile = Join-Path $pdfPath "test.pdf"
$SetsOfPages = 3
$Match = 'NumberOfPages: (\d+)'
$NumberOfPages = [regex]::match((pdftk $pdfFile dump_data),$Match).Groups[1].Value
"{0,2} pages in {1}" -f $NumberOfPages, $pdfFile

for ($Page=1;$Page -le $NumberOfPages;$Page+=$SetsOfPages){
  $File = Get-Item $pdfFile
  $Range = "{0}-{1}" -f $page,[math]::min($Page+$SetsOfPages-1,$NumberOfPages)
  $OutFile = Join-Path $pdfPath ($File.BaseName+"_$Range.pdf")
  "processing: {0}" -f $OutFile
  pdftk $pdfFile cat $Range output $OutFile
}

已编辑，以处理可变的页面集并正确处理突出部分.
再次发现缩短前一组页面的方法要简单得多.

Edited to work with variable sets of pages and to properly handle the overhang.
Edited again: found a much easier way do shorten the last set of pages.
