| artifexirc-bot | <unixbsd> hi | 09:16.56 |
| | <unixbsd> with GS on linux | 09:16.58 |
| | <unixbsd> how to know how much Pages has a given PDF ? | 09:17.08 |
| | <unixbsd> gs .... file.pdf ? to retun 60 pages | 09:17.16 |
| | <KenSharp> Depends which version you are using | 09:17.24 |
| | <KenSharp> For versions prior to 9.56.1 use the pdf_info.ps file in ghostpdl/lib | 09:17.58 |
| | <unixbsd> the one of debian retropie | 09:18.10 |
| | <unixbsd> gs --help | 09:18.23 |
| | <unixbsd> GPL Ghostscript 9.26 (2018-11-20 | 09:18.24 |
| | <KenSharp> That means nothing to me, we don't package for Linux | 09:18.27 |
| | <KenSharp> Right that's old, you should upgrade anyway | 09:18.35 |
| | <KenSharp> But in tny event use the PostScript program in ghostpdl/lib.pdf_info.ps | 09:18.51 |
| | <unixbsd> gs vers https://termbin.com/cwc3o | 09:18.51 |
| | <unixbsd> does GS 9.26 have a feature to display how much pages | 09:20.56 |
| | <unixbsd> ? | 09:20.57 |
| | <KenSharp> Not directly, you need to use the PostScript progam which is supplied as part of Ghostscript. | 09:21.26 |
| | <KenSharp> In ghostpdl/lib look for pdf_info.ps One of the pieces of information supplied by that program is the number of pages in a PDF file | 09:22.09 |
| | <unixbsd> ok, pdf2ps is used. pdf ==> ps ... done . what next? | 09:22.37 |
| | <KenSharp> No, I didn't say anything about pdf2ps | 09:22.51 |
| | <KenSharp> Start with the PDF file, use Ghostscript and the pdf_info.ps program. That program will tell you how many pages are in a PDF file | 09:23.20 |
| | <unixbsd> gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combine.pdf -dBATCH file.pdf <--- that was my workaround | 09:24.57 |
| | <KenSharp> I'm sorry I really don't understand you. Your question was 'How to find the number of pages in a PDF file'. The answer to your questions is 'Use teh pdf_info.ps program'. If you have a different question please ask that. | 09:25.54 |
| | <unixbsd> you mean by : ghostscript file.pdf and type pdf_info.ps ? | 09:34.04 |
| | <unixbsd> Error: /undefined in pdf_info.ps | 09:34.55 |
| | <KenSharp> No. | 09:39.42 |
| | <KenSharp> If you open the file pdf_info.ps then it has usage information in it. If you try to run the file (as one would normally do with Ghostscript) Eg: | 09:40.27 |
| | <KenSharp> gs /ghostpdl/lib/pdf_info.ps | 09:40.28 |
| | <KenSharp> Then it will display a usage message | 09:40.29 |
| | <KenSharp> % usage: gs -dNODISPLAY -q -sFile=____.pdf [-dDumpMediaSizes=false] [-dDumpFontsNeeded=false] [-dDumpXML] | 09:41.05 |
| | <KenSharp> % [-dDumpFontsUsed [-dShowEmbeddedFonts] ] lib/pdf_info.ps | 09:41.05 |
| | <KenSharp> The '%' characters are PostScript comments, obviously you do not include those | 09:41.26 |
| | <KenSharp> So for your prurpose, something like: | 09:41.54 |
| | <KenSharp> gs -dNODISPLAY -sFile=file.pdf /ghostpdl/lib/pdf_info.ps | 09:42.24 |
| | <KenSharp> The file pdf_info.ps is a PostScript program, not a Ghostscript command line switch, you need to execute the program with teh interpreter | 09:42.51 |
