| kens | netrate, as I said on comp.lang.postscript (and probably on Stack Overflow) and here, the developers are either in Europe or the US. I'm afraid you are trying to talk to us when there's nobody here. Don't ask to ask a question, just ask the question. Then come back and read tjhe logs for the answer. | 09:56.47 |
| netrate | just wondering if anyone can help me with my question on how to install and run ghostscript. This is for non-commercial use | 15:33.06 |
| chrisl | netrate: Can you restate your question please? | 15:33.45 |
| netrate | ok, so my question is this. I want to install and run ghostscript on a networked computer | 15:34.31 |
| | I am not allowed to install anything to the Boot drive, but I do have a drive that I can install to... | 15:34.50 |
| kens | The answer is the same as all the other times I've ststed it. Ghostscript deosn't need to be 'installed'. If you're having trouble using it, then you need to tell us what the problem actually is | 15:35.15 |
| netrate | I am using python and pycharm and want to use ghostscript inside of python to convert ps to png/pdf/jpg | 15:35.20 |
| chrisl | This is Windows? | 15:35.36 |
| netrate | windows 7 | 15:36.01 |
| | ok, how do I go about using it in the manner where I can convert ps to pdf? | 15:36.16 |
| kens | gswin32c (or gswin64c) -sDEVICE=pdfwrite -sOutputFile=<out.pdf> | 15:36.38 |
| | Oops forgot the input file, goes on the end | 15:36.50 |
| | Obviously you'll need to supply the path to the Ghostscript binaries | 15:37.10 |
| netrate | ok where do I run the command from? | 15:37.12 |
| kens | That would be the Windows COmmand Shell | 15:37.21 |
| netrate | ok, so I would type cmd | 15:37.34 |
| | go into the directory that I have downloaded ghostscript | 15:37.50 |
| | and then type gswin32c (or gswin64c) -sDEVICE=pdfwrite -sOutputFile=<out.pdf> ? | 15:38.06 |
| kens | The standard Windows binary is a Windows installer. | 15:38.08 |
| | You'll need to run that in order to get a Windows installation | 15:38.22 |
| | Then you can copy the contents of that folder to 'soemwhere else' | 15:38.32 |
| netrate | ok I am confused, you said it didn't need to be installed? Did I understand that wrong? | 15:38.42 |
| chrisl | Or just tell the installer to put it where you want | 15:38.50 |
| kens | No there are two points | 15:38.53 |
| | WHat we supply as a binary for Windows is an installer, you haev to install that. But that's not Ghostscript, that's an installer | 15:39.44 |
| | Its just a way to get Ghostscript onto your maching | 15:39.53 |
| netrate | ok I need to start over then because I am a bit confused now. I have downloaded the file to my personal drive. I have run the gs922w32.exe file. | 15:40.01 |
| kens | Ghostscript itself doesn't actually need 'installing' you can copy it around | 15:40.06 |
| netrate | it has created folders and such in that directory | 15:40.10 |
| kens | Right | 15:40.14 |
| | Then you are good to go | 15:40.31 |
| netrate | ok, so I don't know where to go from here. I am sorry about the confusion | 15:40.57 |
| kens | Run gswin32c (or gswin64c) from that directory | 15:41.10 |
| | Actually I see you installed the 32-bit version so it'kll be gswin32c | 15:41.33 |
| netrate | ok it opened up a command window | 15:41.44 |
| | and you are saying to type in the gswin32c (or gswin64c) -sDEVICE=pdfwrite -sOutputFile=<out.pdf> | 15:41.53 |
| | at this point? | 15:41.56 |
| kens | That's the interactive prompt | 15:41.57 |
| | You don't want that | 15:42.02 |
| | type quit | 15:42.06 |
| netrate | ok | 15:42.16 |
| | I have quit | 15:42.17 |
| kens | Then type the command line I gave earlier | 15:42.19 |
| netrate | I am not sure where you want me to type in this command since I just quit the command prompt | 15:42.41 |
| kens | In case that's not clear : | 15:42.47 |
| | gswin32c -sDEVICE=pdfwrite -sOutptuFile=out.pdf <input.ps> | 15:42.47 |
| | Sorry that's a typo, shoudl be -sOutputFile=out.pdf | 15:43.26 |
| netrate | Ken, I am really sorry, and I know that tech support isn't always easy, but I am not sure where I am supposed to type this command | 15:44.08 |
| kens | In the command shell | 15:44.16 |
| netrate | do I need to be in the path of ghostscript? | 15:44.37 |
| kens | Where you typed gswin32c, type : | 15:44.42 |
| | gswin32c -sDEVICE=pdfwrite -sOutptuFile=out.pdf <input.ps> | 15:44.42 |
| netrate | right now I am in the C drive. | 15:45.00 |
| kens | If you haven't added this directory to your $PATH environment variable, then yes you will need to be in the directory where the Ghostscript binary is | 15:45.09 |
| netrate | ok, how do I add the path directory? | 15:45.29 |
| | is this something I need to do in cmd or in python? | 15:45.42 |
| kens | That's a question about Windows | 15:45.45 |
| | Lets leave that aside for now | 15:45.59 |
| netrate | ok | 15:46.01 |
| kens | Get Ghostscript working | 15:46.04 |
| netrate | Ok I am in the ghostscript directory via the cmd prompt | 15:46.25 |
| kens | So type the command I gave | 15:46.34 |
| | Remember of course that <input.ps> needs to be replaced by the full path and name of hte input PostScript file | 15:46.59 |
| Robin_Watts | Urm, wait... | 15:47.15 |
| | There was a typo in kens line. | 15:47.21 |
| kens | I said that earlier | 15:47.30 |
| netrate | ok | 15:47.33 |
| Robin_Watts | gswin32c -sDEVICE=pdfwrite -sOutputFile=out.pdf <input.ps> | 15:47.47 |
| kens | Yeah I corrected myself above Robin_Watts | 15:47.55 |
| netrate | I am using 64c, so I changed it to gswin64c, right? | 15:48.05 |
| Robin_Watts | I can't see the correction, but OK. | 15:48.08 |
| kens | If you're using the 64-bit version then yes, gswin64c | 15:48.22 |
| netrate | syntax of the command is incorrect, double checking what I typed | 15:49.04 |
| kens | Should be | 15:49.22 |
| | swin64c -sDEVICE=pdfwrite -sOutputFile=out.pdf <input.ps> | 15:49.38 |
| | Oh for Pete's sake I hate this keyboard.... | 15:49.52 |
| | gswin64c | 15:49.56 |
| netrate | Is there a way of copy/paste to the cmd prompt? | 15:50.52 |
| kens | You don't want to do that | 15:51.03 |
| netrate | I put the .ps file in the same directory as gs | 15:51.07 |
| kens | OK | 15:51.14 |
| netrate | does the ps file need to have the <> around it? | 15:51.16 |
| kens | No, that's intended to show you its an argument you need to replace | 15:51.30 |
| | What is the name of the input file ? | 15:51.38 |
| netrate | ok let me try again | 15:51.38 |
| | it says gswin64c is not recognized as an internal or external command | 15:52.09 |
| kens | Then you are not in the directory where you installed Ghostscript | 15:52.29 |
| | list the directory contents using dir | 15:52.38 |
| netrate | ok going to the bin file now | 15:52.40 |
| | ok it brought up the ghostscript window | 15:54.24 |
| | and says press return to continue | 15:54.32 |
| kens | so do that | 15:54.36 |
| netrate | now at the gs prompt | 15:54.43 |
| kens | right type quit | 15:54.47 |
| | and your PDF file should be in that directory | 15:54.54 |
| netrate | ok it created the pdf, that works | 15:55.09 |
| kens | Right | 15:55.14 |
| | So a couple more sueful switches | 15:55.22 |
| Robin_Watts | It might be worth using: gswin64c -sDEVICE=pdfwrite -o out.pdf in.ps in future. | 15:55.29 |
| | That will avoid the prompts. | 15:55.33 |
| netrate | ok, so I know that works. Thank you. My next issue is getting it to work inside of python | 15:55.42 |
| kens | -dBATCH doesn't enter the command shell but exits traight away and -dNOPAUSE doesn't prompt between pages | 15:55.58 |
| | Can't tel lyou anything about Python | 15:56.12 |
| chrisl | netrate: I'd suggest heading over and reading: https://docs.python.org/3/using/windows.html | 15:56.13 |
| | especially the bit about "Configuring Python" | 15:56.32 |
| netrate | I know I need to set the paths | 15:56.40 |
| chrisl | Well, you're good to go! | 15:57.10 |
| netrate | no, not really. I don't know anything about configuring paths | 15:57.25 |
| | I always assumed that GS worked ,it is getting it working from inside of python | 15:57.44 |
| | the GS program does exactly what it is supposed to do. It is great for that. | 15:58.05 |
| | I will have to continue my research on how to get the paths set up. Thanks for that help | 15:58.24 |
| kens | Setting the PATH environment variable: | 15:58.30 |
| | https://www.java.com/en/download/help/path.xml | 15:58.30 |
| chrisl | Note that you probably need to set PYTHONPATH, rather than just PATH | 15:58.56 |
| kens | Also: | 15:58.58 |
| | https://www.computerhope.com/issues/ch000549.htm | 15:58.58 |
| | And teh page Chris mentioned on configuring Python has instructions for this as well | 15:59.58 |
| netrate | ok I will try. Thank you. | 16:00.09 |
