| sine0 | kens: | 12:53.55 |
| kens | ? | 12:54.01 |
| sine0 | is it possible to view what metadata a pdf has | 12:54.03 |
| | like hidden information about the creator/computer and stuff | 12:54.16 |
| kens | I'm not sure what you mean by 'hidden' data, there isn't any in the PDF Metadata. Possibly you mean the XML metadata ? | 12:56.07 |
| | Or soemthing non-standrad ? | 12:56.14 |
| | But I doubt Ghostscript will do that for you. Again, you should probably look at MuPDF. You can retrieve stuff using MuPDF and script it using JavaScript | 12:56.54 |
| chrisl | pdf_info.ps might do? | 12:57.16 |
| kens | It only retrieves certain things. If I knew more exactly what you were trying to retrieve I could be more specific but lacking an example I can onl ytalk in general terms | 12:58.03 |
| sine0 | just anything that would identify the creator | 12:59.59 |
| chrisl | It can do the XML metadata - for anything *really* nonstandard, I doubt any "standard" consumer will work | 12:59.59 |
| | Like the Creator key? | 13:00.10 |
| kens | sine0 well as chrisl says the pdf_info.ps program can retrieve a bunch of stuff, I believe the Creator is in there | 13:00.26 |
| chrisl | But I think that kind of meta-data is optional (although widely used) | 13:01.06 |
| sine0 | https://bpa.st/KPOA | 13:01.13 |
| kens | Well pdf_info.ps isn't going to retrieve all that | 13:01.42 |
| sine0 | I had exiftool installed that seems to show quite alot | 13:01.49 |
| kens | The bits marked [PDF} it willdo, at least some of them. Language is a nonsense I suspect | 13:02.09 |
| chrisl | pdf_info.ps should get *lot* of that | 13:02.18 |
| kens | You can't readily tell the language of a PDF file | 13:02.25 |
| | Yeah quite a bit | 13:02.30 |
| chrisl | sine0: You can give it a try: https://git.ghostscript.com/?p=ghostpdl.git;a=blob;f=lib/pdf_info.ps | 13:03.03 |
| | Usage is in a comment at the top of the file | 13:03.16 |
| kens | Tried it on ghostpdl/examples/annots.pdf and got the Title, Author, Creator, Producer, CreationData, ModDate, the MediaBox for each page and the required (not embedded) fotns. | 13:03.48 |
| | gs -dNOSAFER -sFile=/ghostpdl/examples/annots.pdf /ghstpdl/lib/pdf_info.ps | 13:05.30 |
| chrisl | It'll optionally print out the XML metadata, too | 13:06.04 |
| kens | If you set DumpXML it will also give teh embedded XML M<etadata | 13:06.06 |
| | LOL | 13:06.10 |
| | Also FontsUsed and EmbeddedFonts are available | 13:06.23 |
| | So really quite a lof of information. I think it will also tell you if the PDF fiel uses transparency | 13:06.43 |
| | AFK for a short while | 13:08.50 |
| Lelldorin1 | hello all | 18:13.34 |
| | anyone aroud who have expierirence in gs on Haiku? | 18:13.47 |
| | gs -sDEVICE=pdfwrite -sOutputFile=image%d.ps -dBATCH -dNOPAUSE /boot/home/Desktop/testaa.pdf | 18:13.50 |
| | this command line exports onle one file not every site as single file | 18:14.06 |
| Robin_Watts_ | No idea about haiku. | 18:18.31 |
| | Surely you mean image%d.pdf ? | 18:18.42 |
| | What version of gs are you using? | 18:18.51 |
| | pdfwrite is NOT a printer device, hence I'm not sure %d works with it. | 18:19.34 |
| Lelldorin1 | ho Robin_Watts_ | 18:20.30 |
| | AFPL Ghostscript 8.14 (2004-02-20) | 18:20.34 |
| kens | Lelldorin1: I doubt you'll find anyone using Haiku here I'm afraid | 18:20.34 |
| Lelldorin1 | pdfwrite is the right device on haiku os | 18:20.43 |
| kens | Right so that's an ancient version of GS, you need to upgrade sto eomsthing less than 10 years old | 18:20.54 |
| Robin_Watts_ | Lelldorin1: Ah, come back a decade ago and ask us :) | 18:20.56 |
| Lelldorin1 | Robin_Watts_: thanks you make me hoping broken ;-) | 18:21.48 |
| | sorry bad english | 18:22.21 |
| kens | 8.14 is 16 years old, its not entirely surprising to me that there might be a bug (or simply %d is not implemented) in code that old | 18:22.26 |
| Lelldorin1 | i can use v 9.50 | 18:23.44 |
| | but is old too? | 18:23.50 |
| kens | Well that's certainly an improvement | 18:23.56 |
| | Its reasonably recent,only a year or so old I think | 18:24.09 |
| | 9 months according to our Git erpository | 18:24.30 |
| Lelldorin1 | ok i will try with it, thanks | 18:24.34 |
| kens | No problem | 18:24.55 |
| Lelldorin1 | it was the problem thanks :-) | 18:29.09 |
