| jhabjan | Hi, It has been a while since last time chatting here. Not sure if you remember me but I'm the author of Ghostscript.NET. | 07:38.37 |
| kens | Morning Josip | 07:38.59 |
| jhabjan | Lately I see a lot of reports people complaining about Ghostscript.NET not being able to retreive total PDF page count. It looks like it's not consistent and it works with some ghostscript versions and not with others. | 07:39.25 |
| kens | As I understand what I'm seeing.... | 07:39.44 |
| | Ghostscript.NET is trying to use teh PDF ProcSet dictionary | 07:40.02 |
| jhabjan | I've put together all ps I'm using in Ghostscript net to get all pdf information: https://pastebin.com/YCvhRaFp | 07:40.16 |
| kens | We removed access to that in 9.27 because people were using it to bypass the SAFER security. OK let me look at that | 07:40.35 |
| jhabjan | I use %GSNET_VIEWER_PDF_PAGES: to trap STD out | 07:40.36 |
| chrisl | Yep, using GS_PDF_ProcSet | 07:40.58 |
| kens | OK you can no longer use GS_PDF_ProcSet begin | 07:41.08 |
| jhabjan | is there any other alternative way of getting page count? | 07:41.31 |
| kens | Yes, but I'll need to go look it up | 07:41.39 |
| jhabjan | no worries, no pressure, I believe you have my email address so when you grab some time you can email me if you want | 07:42.40 |
| kens | Not sure about your email address, but I bet I can find it | 07:43.01 |
| chrisl | You can see the changes done for one of our tools here: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=db24f253409d5d085c2760c814c3e1d3fa2dac59 | 07:43.08 |
| kens | Yeah I think you just want to dump the GS_PDF_ProcSet begin | 07:43.53 |
| | And pdfdict begin | 07:44.28 |
| | Just do (filename.pdf) runpdfbegin and pdfpagecount | 07:45.44 |
| jhabjan | Great, I'll give that a go. | 07:47.31 |
| kens | I don't see where that code actually does anything with the pages though | 07:47.48 |
| | jhabjan: with the current code (9.28 release candidate) you'll either need to run with -dNOSAFER or take action to permit the input file to be read | 07:48.37 |
| jhabjan | I parse str out and put page count in variable so it's available from .NET | 07:49.15 |
| kens | Oh OK, I was just thinking I don't see anythign that runs the pages, as long as you know what its doing :-) | 07:50.03 |
| jhabjan | what exactly do you mean by 'take action to permit' ? | 07:51.06 |
| kens | You really ought to do a runpdfend on the file, and if all you want is the page count, then you don't need process_trailer_attributes | 07:51.11 |
| | jhabjan, we now default to using SAFER. | 07:51.19 |
| | That blocks access to directories and files. | 07:51.40 |
| | Unless (on the command line) you specifically add those files/directories to one of 3 lists | 07:51.58 |
| | PermitFileReading, PermitFileWriting, PermitFileControl | 07:52.10 |
| | Its documented in the latest release notes and manual | 07:52.23 |
| | One the interpreter is running, you csannot change access to files and directories | 07:52.42 |
| jhabjan | ah, ok, got it | 07:52.55 |
| kens | I need too fetch coffee, back in 5 minutes | 07:54.02 |
| jhabjan | Thank you for help and tips | 07:54.06 |
| kens | NP let me know if there are still problems | 08:05.45 |
| | LOL I just earned a gold badge for 'Ghostscript' in Stack Overflow | 08:08.04 |
| jhabjan | Sure, np. Congrats on gold badge. | 08:08.55 |
| kens | Just amused :-) | 08:09.08 |
| ator | kens: a somewhat late reward, I would think :) | 09:38.37 |
| kens | Well you have to earn it.... | 09:38.54 |
| | Bet I've got the only one though :-) | 09:39.07 |
| svs | Hi, I have a server that has 130 printers installed and I am trying to print a test PDF to one of the printers from the command line using gswin64. When I specify the printer using the -sOutputFile flag, I get a GPL Ghostscript has stopped working error, but if I leave this flag off and print to the default printer it works. Does anyone have any id | 21:44.19 |
| | eas what might be causing it? | 21:44.19 |
| | Here is the command I am running that is throwing the error: gswin64.exe -dPrinted -sDEVICE=mswinpr2 -sOutputFile=%printer%WL2D2 testing.pdf | 21:45.39 |
