| | <<<Back 1 day (to 2018/08/28) | 20180829 |
| deekej | hey guys :) I saw you jumped to 9.25 version for upcoming release... Is there some more significant change coming? :) | 11:31.59 |
| chrisl | We're getting 9.24 ready, so master moves to 9.25 | 11:48.29 |
| deekej | ah, ok :) | 12:03.08 |
| aiena | I channot download ghostscript for windows. When I visit http://downloads.ghostscript.com/public the http server says pageok as a response but there are no links to files. | 14:01.13 |
| | Is something wrong? | 14:01.31 |
| chrisl | Go to https://ghostscript.com/ | 14:01.50 |
| aiena | yes | 14:02.11 |
| | the other page's hyperlink is wrong | 14:02.21 |
| chrisl | Other page? | 14:02.34 |
| aiena | can this url also link back to the dowload page | 14:02.37 |
| | I mean can http://downloads.ghostscript.com/public redirect to https://ghostscript.com/download.html | 14:03.03 |
| | some web pages still have the old hyperlink | 14:03.11 |
| | both are up | 14:03.14 |
| chrisl | I'm not sure - I'll have to ask some to look into it. We'll do it if we can | 14:04.08 |
| aiena | thank you | 14:04.16 |
| | the first url looks correct but is wrong | 14:04.39 |
| | it used to work earlier | 14:04.49 |
| | so the change is more recent if it at least gave a 404 not found | 14:05.02 |
| | it was better | 14:05.04 |
| | I'll try to report to the other site too | 14:05.25 |
| | err other project too so they can update the link | 14:05.36 |
| chrisl | Trouble is, we don't have that old site now, so if we can do it, it'll have to be through DNS | 14:05.48 |
| aiena | Scribus got the wrong url still | 14:05.50 |
| | oh then don't bother | 14:06.04 |
| | hmm wait | 14:06.11 |
| | but both are same domain | 14:06.16 |
| | downloads. looks like a subdomain of ghostscript.com only right | 14:06.32 |
| kens | site != domain | 14:06.35 |
| aiena | so shouldn't it be same server | 14:06.46 |
| kens | The old website has been replaced, even though its on the same domain | 14:07.00 |
| aiena | hmm you mean downloads.ghostscript.com isn't owned/managed by you'll anymore | 14:07.44 |
| kens | I'm not certain exactly which subdomains we have now | 14:07.50 |
| | We did some rationalisation a while back | 14:08.23 |
| aiena | don't know command for dns lookup on windows (: | 14:08.43 |
| | yeh their different servers | 14:10.15 |
| | i'll report in the other place i'll try to fix it at root first | 14:10.33 |
| | yeah | 14:10.42 |
| | thanks kens chrisl | 14:13.23 |
| kens | NP thanks for mentioning it, we'll see what we can do | 14:13.34 |
| aiena | nods | 14:15.33 |
| | Just curious is it possible to extract postscript code from a pdf | 14:30.37 |
| chrisl | Extract? PDF doesn't contain Postscript | 14:31.09 |
| kens | Unless it has a PostScript XObject :-) | 14:31.26 |
| | Which is unusual, deprecated, and a seriously bad thing indeed | 14:31.40 |
| aiena | oh | 14:31.55 |
| | what does pdf2ps do on linux? | 14:32.02 |
| kens | Our shell script ? | 14:32.19 |
| aiena | not sure what it is | 14:32.27 |
| | on linux they appear as commands/exe's unless you dig deep | 14:32.40 |
| | i don't have linux on this system | 14:32.47 |
| kens | It runs Ghostscript and uses the ps2write devie. That works the same way as teh pdfwrite device. It interpretes the input, producing marking primitives from it. The device then reassembles the marking primitives into the required output. For ps2write that's PostScript for pdfwrite its PDF. The process is deatiled in vectordevices.htm in our documentation | 14:33.39 |
| | https://www.ghostscript.com/doc/9.23/VectorDevices.htm#Overview | 14:34.28 |
| aiena | was typing out pure postscript for fun in the gs shell | 14:37.26 |
| | doubt i'll ever really do tht though | 14:37.36 |
| kens | Only fools like us do that :-) | 14:37.51 |
| aiena | nah | 14:37.59 |
| | you'll made an amazing produc | 14:38.05 |
| | product | 14:38.08 |
| kens | Writing a lengthy program on the fly isn't really sensible | 14:38.10 |
| aiena | which makes things like scribus possible | 14:38.20 |
| | your enable DTP with OSS | 14:38.29 |
| | *you'll | 14:38.33 |
| | apprecite your hard work so much | 14:38.52 |
| kens | Nowadays PDF is more important than PostScript, or at least, equally important | 14:38.57 |
| aiena | though its absolutely non geek friendly | 14:39.01 |
| | yeah but gs does pdf too | 14:39.13 |
| | i don't know if its only a postscript interpreter anymore | 14:39.24 |
| kens | Indeed, and the PDF itnerpreter in Ghostscript is written in PostScript :-S | 14:39.32 |
| aiena | wow | 14:39.42 |
| | mean ps is geek friendly | 14:40.24 |
| | its so tedious to draw box in ps | 14:40.38 |
| kens | Too much so it seems, recently | 14:40.45 |
| aiena | it's sort of like the svg spec | 14:40.46 |
| | inkscape saves us lol | 14:41.02 |
| | svg spec looks hell compared to ps | 14:41.15 |
| kens | So does the ISO PDF spec :-( | 14:41.27 |
| aiena | don't know anything about that | 14:41.45 |
| | engineers like to make amazingly convoluted stuff that just works | 14:41.58 |
| | like gs :P | 14:42.17 |
| | joking | 14:42.21 |
| kens | Trust me, if you want to read teh PDF spec, start with the Adobe published spec for 1.7. Only read teh ISO spec for 2.0 to find out what changed | 14:42.24 |
| aiena | I'll read it. Not an engineer. | 14:42.59 |
| | I am self taught geek lol | 14:43.03 |
| kens | Umm, its not something you probably want to read for fun, pretty large | 14:43.23 |
| aiena | I don;t know how you'll digest all that | 14:43.26 |
| | I did read it though once | 14:43.32 |
| | because I was forced to open a pdf in a text editor | 14:43.45 |
| | I was trying to hunt what from latex was creating a type 1 font in the pdf | 14:44.05 |
| kens | That's usually a fairly fruitless exercise | 14:44.11 |
| aiena | pdf still gives some useful info in plain text among a ton of gibberish | 14:44.22 |
| | I did find it | 14:44.30 |
| kens | Soemtimes, but more and more rarely | 14:44.34 |
| aiena | it was something in pstricks lol | 14:44.35 |
| | once they start zipping pdfs natively | 14:45.11 |
| | it's the end I think | 14:45.18 |
| kens | PDF files are, generally compressed with Flate | 14:45.31 |
| aiena | you'll need to decompress to get some plain text among gibberrish | 14:45.35 |
| | hmm how can i decompress them | 14:45.44 |
| kens | and from version 1.5 the xref and objects are often in a binary seuqence which is then compressed | 14:45.53 |
| | You can use MuPDF to decompress a PDF file | 14:46.02 |
| | mutool clean -d <output.pdf> <input.pdf> | 14:46.13 |
| aiena | us mupdf commercial | 14:47.06 |
| | or free for personal use | 14:47.09 |
| kens | Same licence as GS | 14:47.18 |
| | AGPL | 14:47.25 |
| aiena | ok amazng how you give these tools for free | 14:47.28 |
| | God bless you | 14:47.32 |
| kens | Well we seel them too | 14:47.38 |
| | Otherwise we wouldn't get paid and that would be bad ! | 14:47.50 |
| aiena | yeah i know | 14:47.58 |
| | But I don't know if you'll get revenue. | 14:48.11 |
| | Artifex license is the commercial one | 14:48.24 |
| kens | We do OK. We aren't Google or anything, but we manage | 14:48.27 |
| aiena | If yu'll get paid for support its good | 14:48.42 |
| | because support is a recurring fee | 14:48.52 |
| | and can feed a person | 14:48.55 |
| kens | We don't charge for support. Our commercial custoemrs pay for a licence and we support them for free, as normal for commercial transactions. Free users technically don't get support. But we reckon we get value form habving people kick the tyres so we foten answer questions and we will always fix bugs | 14:49.50 |
| aiena | Well ironically free users make your product better | 14:50.25 |
| | more testing | 14:50.28 |
| kens | Yes exactly | 14:50.32 |
| aiena | so the commercial product becomes a ton better | 14:50.43 |
| kens | Yep, we often have buigs fixed before customers even know they are there. | 14:50.59 |
| aiena | if you see OSS projets develop way faster and are better quality than closed source software | 14:50.59 |
| | the ones that kickoff | 14:51.10 |
| kens | Also, we get free advertising, in a sense | 14:51.11 |
| aiena | so many bright k\minds | 14:51.17 |
| | true | 14:51.19 |
| | oublicity | 14:51.22 |
| | publicity | 14:51.26 |
| | tke Krita for example | 14:51.37 |
| | from one tiny thing its evolved to become so amazing. | 14:51.56 |
| | I am wondering what gs was like in the early days | 14:52.07 |
| | did the task feel impossible to you at that point | 14:52.14 |
| kens | I can't answer that, I've only been working on Ghostscript for 11 years | 14:52.32 |
| aiena | given how large the pdf spec was | 14:52.33 |
| | and how old is gs? | 14:52.42 |
| kens | Around 30+ | 14:52.52 |
| aiena | Oh wow | 14:53.03 |
| kens | I'm not sure of the exact date of the first release | 14:53.04 |
| aiena | so it sort of may have started as the pdf spec evolved | 14:53.18 |
| kens | It started with level 1 PostScript | 14:53.26 |
| aiena | or waaay before pdf | 14:53.31 |
| | oh | 14:53.33 |
| kens | Then added level 2, then level 3 then PDF 1.0 etc | 14:53.38 |
| aiena | yeah | 14:53.46 |
| | probably if someone were to attempt a gs from scratch now | 14:53.56 |
| | it would be impossible but then it was gradual enhancement | 14:54.12 |
| kens | There are people who do. There's Luser Droog over in comp.lang.postscript in UseNet. As far as I know he's still writing his PostScript interpreter | 14:54.32 |
| aiena | I wonder what motivates these people | 14:55.03 |
| | when there is already a great ps interpreter | 14:55.11 |
| kens | Usually a combination of things. | 14:55.26 |
| | Curiosity, interest in the subject, a desire to do better. | 14:55.49 |
| | Plus of course, no life :-) | 14:55.56 |
| aiena | lol https://groups.google.com/forum/#!topic/comp.lang.postscript/U8p7v7SzIMc | 14:58.33 |
| | is facinating | 14:58.37 |
| | gs is too slow for him and someone suggests imagemagick which uses gs hahahaha | 14:58.53 |
| kens | Yep :-) | 14:59.00 |
| aiena | im will be way worse | 14:59.09 |
| | it has the image conversion overhead too | 14:59.16 |
| | and the server memory will be stressed | 14:59.32 |
| chrisl | Generally people who complain gs is too slow don't really understand what it has to do | 14:59.33 |
| aiena | yeah I guess | 14:59.50 |
| | does anyone really understand what gs needs to do | 14:59.59 |
| kens | I think there's a javascript implementation of PostScript. But its incomplete, and if he thinks *Ghostscript* is slow..... | 15:00.16 |
| aiena | I have a wild imagination and some experience so I can imagine | 15:00.19 |
| | kens: he's approaching it wrong | 15:00.34 |
| kens | Probably yes | 15:00.41 |
| aiena | he wants the ps to pdf conversion to be inline with a web paage render | 15:00.51 |
| | he needs to design the system so the processing is offloaded to some other server | 15:01.18 |
| | and the database just stores the status of the conversion | 15:01.30 |
| | or something similar | 15:01.34 |
| | then render the ps as pdf when ready | 15:01.44 |
| kens | Possibly yes. I didn't reply to him because it wasn't clear to me exactly what he wanted and why | 15:01.46 |
| | And other people already ahd, so.... | 15:02.00 |
| aiena | lol | 15:02.44 |
| | each repy made it worse for the original poster | 15:03.04 |
| | lmao | 15:03.06 |
| | one suggested compiling a custom browser | 15:03.20 |
| | which makes the js interpreter use gs | 15:03.28 |
| | pretty sensible in the sense the pdf processing is offloaded to the client | 15:03.43 |
| | but hard to pull off | 15:03.46 |
| | bye for now | 15:04.57 |
| kens | bb | 15:05.08 |
| aiena | sorry for wasting your time i like to talk lol | 15:05.10 |
| byoungb | I tried searching through the IRC logs to see if this had already been answered. But is there an ETA on a new relase fixing VU#332928 | 15:08.29 |
| kens | We are working on a release currently | 15:08.44 |
| | It normally takes us ~1 week of QA | 15:08.52 |
| | In the meantime, patches are already available in our Git repository | 15:09.07 |
| byoungb | okay cool I will apply them to my own RPM for now thanks. So should I just checkout the latest version on git? | 15:10.02 |
| kens | You could check the 9.24 release tag if you want to match our release | 15:10.25 |
| | Though I think currently that is probably the same as our HEAD | 15:10.45 |
| byoungb | awesome thankyou very much | 15:11.09 |
| kens | You're welcome | 15:11.19 |
| | Forward 1 day (to 2018/08/30)>>> | |
