Powershell脚本可将特定的PDF页面打印到图像中 [英] Powershell script to print specific PDF pages into images

问题描述

如何更改此powershell脚本

How I could I change this powershell script

Start-Process –FilePath "C:\Data\PROJECTS\ABC.pdf" –Verb Print -PassThru | %{sleep 10;$_} | kill

收件人:

1. 打印PDF的特定页面，
2. 直接转到图像(例如png，jpg，tif等)，并且
3. 相应保存吗?

例如，我想将ABC.pdf的第3、4、7页打印到三个分别称为ABC_3.png，ABC_4.png和ABC_7.png的文件中；图片文件可以是任何格式(.png，.jpg，.tif等).

For example, I want to print pages 3,4,7 of ABC.pdf into three separate files called ABC_3.png, ABC_4.png, and ABC_7.png; the image file can be any format (.png, .jpg, .tif, etc.).

我计划调用.csv列表以获取所有参数值(例如要打印的页码，带有页码的输出名称，新文件位置的文件路径等)，但是我不知道如何设置powershell语法.谢谢.

I plan to call on a .csv list to get all the parameter values (e.g. page number to print, output name with page number, filepath to new file location, etc) but I don't know how to set up the powershell syntax. Thank you.

更新:

我已经通过下面的脚本在此任务上取得了进展，该脚本调用了一个幽灵cri.它执行上面的1-3，除了我似乎无法将csv中的-dFirstPage和-dLastPage设置为参数...我得到了powershell错误:

I've made progress on this task with the script below, which calls on a ghostcript. It does 1-3 above except that I can't seem to set my -dFirstPage and -dLastPage to a parameter from my csv... I get the powershell error:

Invalid value for option -dFirstPage=$pg, use -sNAME = to define string constants

如果我将$ pg替换为一个数字，它似乎可以正常工作.我将如何使用-sNAME来解决此问题?

if I replace $pg with a number it seems to work fine. How would I use -sNAME to fix this?

新脚本

#Path to your Ghostscript EXE
$tool = 'C:\Program Files\gs\gs9.19\bin\gswin64c.exe'

$files = Import-CSV 'C:\Data\files.csv' -Header ("FileName","Type","Map","Section","MapPg","SectionPg","Directory","PathName","LastWriteTime")

ForEach($File in $files) 
{

    if ($File.Map -eq "T" -And $File.Type -eq "pdf")
    {
        $tif = $File.PathName + "_Pg" + $File.MapPg + ".tif"
            $param = "-sOutputFile=$tif"
        $inputPDF = $File.PathName + ".pdf"
        $pg = $File.MapPg
        & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 -dFirstPage='$pg' -dLastPage='$pg' $inputPDF -c quit
    }
    ElseIf ($File.Section -eq "T" -And $File.Type -eq "pdf") 
    {
        $tif = $File.PathName + $File.SectionPg + ".tif"
        $param = "-sOutputFile=$tif"
        $inputPDF = $File.PathName + ".pdf"
        $pg = $File.SectionPg
        & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 -dFirstPage='$pg' -dLastPage='$pg' $inputPDF -c quit
    }
}

推荐答案

此处的关键是将-dFirstPage和-dLastPage移出ghostcript行，并移至新参数(param1和param2)中.以下作品(尽管我想可能会有更好的方法):

The key here was to move the -dFirstPage and -dLastPage out of the ghostcript line and into new parameters (param1 and param2). The following works (although I imagine there may be better ways):

#Path to your Ghostscript EXE
$tool = 'C:\Program Files\gs\gs9.19\bin\gswin64c.exe'

$IPfiles = Import-CSV 'C:\Data\files.csv' -Header ("FileName","Type","Map","Section","MapPg","SectionPg","Directory","PathName","LastWriteTime")

ForEach($File in $IPfiles) 
{
    $pgM = $File.MapPg
    $pgS = $File.SectionPg
    if ($File.Map -eq "T" -And $File.Type -eq "pdf")
    {
        $tif = $File.PathName + "_MPg" + $File.MapPg + ".tif"
            $param = "-sOutputFile=$tif"
        $param1 = "-dFirstPage=$pgM"
        $param2 = "-dLastPage=$pgM"
        $inputPDF = $File.PathName + ".pdf"
        & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 $param1 $param2 $inputPDF -c quit
    }
    ElseIf ($File.Section -eq "T" -And $File.Type -eq "pdf") 
    {
        $tif = $File.PathName + "_SPg" + $File.SectionPg + ".tif"
        $param = "-sOutputFile=$tif"
        $param1 = "-dFirstPage=$pgS"
        $param2 = "-dLastPage=$pgS"
        $inputPDF = $File.PathName + ".pdf"
        & $tool -q -dNOPAUSE -sDEVICE=tiffg4 $param -r300 $param1 $param2 $inputPDF -c quit
    }
}
