| Kobaz | having a problem with gs | 14:45.00 |
| | gs -dNOPAUSE -dBATCH -sDEVICE=pnggray -r300 -dUseCropBox -sOutputFile="/tmp/newloa.pdf" /tmp/loa.pdf | 14:45.27 |
| | Cannot parse integer value ?-dBATCH? for -d | 14:45.33 |
| kens | Where di you get Ghostscript from, what operating system are you using ? | 14:46.01 |
| Kobaz | debian/buster | 14:46.16 |
| | apt-get install | 14:46.19 |
| | oh | 14:46.33 |
| | haha | 14:46.34 |
| | whoops | 14:46.36 |
| | gs --version | 14:46.40 |
| | gnome-screenshot 3.36.0 | 14:46.40 |
| | that might do it | 14:46.42 |
| kens | Then I suggest you start by taking it up with the package maintainer | 14:46.46 |
| | The package maintainers make changes to Ghostscript and we cannot help with those | 14:47.02 |
| Kobaz | /usr/bin/gs -dNOPAUSE -dBATCH -sDEVICE=pnggray -r300 -dUseCropBox -sOutputFile="/tmp/newloa.pdf" /tmp/loa.pdf | 14:47.09 |
| | that worked a bit better | 14:47.13 |
| kens | Or you can get the source from our Git repository and build Ghostscrit yourself | 14:47.15 |
| | In what way better ? | 14:47.32 |
| Kobaz | that it's actually running ghostscript, and not gnome-screenshot | 14:47.43 |
| | $ alias gs | 14:47.54 |
| | alias gs='gnome-screenshot -i' | 14:47.54 |
| chrisl | Kobaz: gnome-screenshot is *also* using the binary name "gs"? Can I ask you to report that upstream please? It will mean more coming from a user (as well as from us) | 14:47.57 |
| Kobaz | i forgot i had that | 14:47.59 |
| kens | LOL | 14:48.14 |
| | Note you are using a PNG outptu devcie but you've given the outptu filename a .pdf extension | 14:48.56 |
| Kobaz | er, right | 14:49.04 |
| | i was switching things around trying to make things works | 14:49.10 |
| | *work | 14:49.12 |
| kens | Not necessarily a problem of course | 14:49.17 |
| Kobaz | what i really wanted was pdf compression | 14:49.26 |
| | but little did i realize I wasn't actually working with ghostscript | 14:49.48 |
| kens | Ghostscript's pdfwrite doesn't do 'PDF compression' | 14:49.52 |
| | The PDF file it produces may be smaller, especially if you use lossy techniques such as downsampling images, but that's not quite the same thing as 'compressing' a PDF file | 14:50.23 |
| Kobaz | gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf | 14:50.55 |
| | is some randomness fom the interwebs | 14:51.19 |
| kens | Well PDFSETTINGS bundles a whole host of settings. I hate it and woudl remove it in a trice if only people wouldn't bitch at me if I did | 14:51.30 |
| | You;d be better off selecting the features you want individually | 14:51.47 |
| | That one will downsample images aggressively and convert everything to RGB | 14:52.10 |
| Kobaz | ah | 15:04.43 |
| | that's fine with me | 15:04.56 |
| kens | OK well if it does anything you don't like you'll have to switch to individual parameters; just as long as you're aware :-) | 15:07.56 |
| quitte | Hi. Is this channel somewhat active? I'm trying to learn some postscript in the hopes of fixing the way my printers select paper. | 19:21.33 |
| | I'd like to access the InputAttributes dictionary. | 19:24.49 |
| | Hmm. I think I may have got it: currentpagedevice begin InputAttributes {== ==} forall | 19:32.20 |
| | If I understand this correctly it does: put the currentpagedevice dict on the dictionary stack put a the InputAttributes dictionary pointer on the command stack and then prints its keys and values | 19:33.50 |
| | I bet I can, but I'd be glad for any pointers: can I load my printers dictionaries into Ghostscript? How? It would be nice if I didn't need a VPN while on the road and instead use Ghostscript as an emulator of my printer | 21:24.34 |
| | Also the timeout in the interactive shell of the printer is getting annoying | 21:25.54 |
