Analogue of the % symbol from cmd to powershell

Question

PowerShell

Good afternoon.
When passing a parameter to Imagemagic's external utility to convert a multi-page .pdf to .tiff, only the first page is converted. While looking for a solution, I came across this code:

convert original.tif output%d.tif

The % character doesn't work in PS the same way it does in CMD, and the output I get is 0.tif at the root with one first page.

$convert = 'C:\Program Files\ImageMagick-6.8.2-Q16\convert.exe'
$one = Get-Item '.\default.pdf'
$one
& $convert -density 200 -compress group4 $one 'c:\%d.tiff'

Tell me how to pass the parameter correctly so that the pages are processed correctly.

Answer 1

Problem solved.
We need to edit the delegates.xml file in the Imagemagic directory. Alpha channel processing section.

<delegate decode="ps:alpha" stealth="True" command=""gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pnmraw" -dTextAlphaBits=%u -dGraphicsAlphaBits=%u "-r%s" %s "-sOutputFile=%s" "-f%s" "-f%s""/>

The utility starts issuing all PDF pages separately, which can then be molded into one tiff with the mogrify command .

Answer 2

It is this method of splitting a multi-page Pdf into pages that is indicated here. It seems like the convert.exe utility itself understands that it is necessary to extract all the pages in a cycle. Therefore, I sin on this symbol.

Answer 3

In a powershell, the iscaping occurs with the symbol ` try `%
