| lasse_ | kens: Are you available? | 08:31.08 |
| | I've been trying to create a PDF/A-1b valid document from a JPEG, but after creating the document I saw that the cropping was off. To the right side of the PDF, there was a thich, white border (the background), which is not acceptable due to my requirements. | 08:35.27 |
| | Has anyone else experienced this? | 08:35.38 |
| chrisl | lasse_: You're probably getting the default page size. You'll need to set the page size to suit your JPEG | 08:36.50 |
| lasse_ | Can this be set automatically based on the jpeg? | 08:38.33 |
| chrisl | You'll have to look at what the viewjpg.ps code does - I really can't remember | 08:39.49 |
| lasse_ | Okay, thanks anyway | 08:40.10 |
| | Lol, the command for what I want is at the bottom of viewjpeg.ps | 08:41.03 |
| chrisl | I was just going to say that..... | 08:41.12 |
| lasse_ | That made it easier | 08:42.21 |
| kens | lasse_ : I'm here now | 09:23.33 |
| lasse_ | Thanks, but I already solved my problem :) | 09:38.22 |
| Jai_ | I'm using Magick.Net to convert images(.PS to .PNG).. So obviously it requires ghostscript to be installed on the server. Is there a way to directly use the ghostscript without installing it?? | 09:38.28 |
| kens | even better | 09:38.29 |
| | Jai_ you don't need to 'install' Ghostscript at all, but I cannot comment onMagick.Net | 09:38.58 |
| | Note that one way or another you will need the binary executable availabe, the easiest way to do that is almost certainly to install Ghostscript. Why do you want to avoid that ? | 09:39.29 |
| | BTW its just Ghostscript, not 'the ghostscript' | 09:40.01 |
| Jai_ | Ha..ha..you are right | 09:40.15 |
| | But | 09:40.18 |
| | On production server we don't install unless there is real need for it | 09:40.48 |
| kens | WErll that's up to you | 09:41.06 |
| Jai_ | Can't we directly extract dll and refer it? | 09:41.22 |
| kens | Its not just a DLL | 09:41.38 |
| | Though clearly I know nothing aout Magick.Net and cannot tell you how that works | 09:41.55 |
| | Possibly that does only need the DLL, I wouldn't know | 09:42.05 |
| | But you might need additional support files as well. | 09:42.28 |
| | I obviously don;t know what you are doing, but..... Have you checked the AGPL licence ? | 09:42.51 |
| Jai_ | Nope..Kens | 09:43.17 |
| kens | Door, back shorlty | 09:43.37 |
| Jai_ | Any thing that seriously need to be considered before installing? | 09:43.52 |
| chrisl | I *think* ImageMagick always calls out to the gs executable, I'm fairly sure it doesn't use a shared lib/DLL | 09:43.58 |
| Jai_ | I'm not sure..just came here to check..if anyone has faced this before | 09:45.45 |
| chrisl | What, installing Ghostscript without installing it? | 09:46.21 |
| Jai_ | *using dlls | 09:47.17 |
| chrisl | Yes, lots of people use the GS dll | 09:47.48 |
| | In fact, our own executables use the DLL | 09:48.06 |
| Jai_ | Anyone who is online...has experience with .net-mvc..Magick.net | 09:50.21 |
| | ?? | 09:50.37 |
| chrisl | Not here, we do Ghostscript | 09:51.29 |
| Jai_ | OK..ghostscript with .NET-MVC | 09:52.03 |
| | ? | 09:52.06 |
| chrisl | I doubt it - you could try Ghostscript.NET - but again, that's not us | 09:53.15 |
| tor8 | Robin_Watts: I've got a transparency question for you. | 09:53.52 |
| | on tor/master, there's a commit to fix bug 695582 (transparency with stroke+fill text) | 09:54.20 |
| | it solves the overlap, but there are antialiasing artifacts :( | 09:54.43 |
| kens2 | back, had ot let exterminator into back garden | 10:04.52 |
| Robin_Watts | tor8: You push/pop a group? | 10:41.09 |
| | seems like a reasonable fix. | 10:43.35 |
| | antialiasing wierdness does not surprise me in the least. | 10:43.47 |
| | Urm... I just looked for Miles in the results of La Carrera Panamericana. | 11:03.06 |
| kens2 | THat doesn't sound good | 11:03.18 |
| Robin_Watts | They listed a time in the first stage of the first day (not the 0th day, cos that's unofficial). | 11:03.30 |
| | But I can't find him listed anywhere since. | 11:03.45 |
| | Oh. wait, I have him on day 2. | 11:04.16 |
| | And he's listed in the "boot order" for day 3, but I don't have him finishing anywhere... | 11:07.25 |
| | I don't have him finishing anything in day 2 either :( | 11:08.34 |
| tor8 | Robin_Watts: yeah... I guess so. | 11:29.30 |
| | Robin_Watts: time to cut a release candidate now? | 11:29.43 |
| Robin_Watts | tor8: Let me look at the buglist again :) | 12:03.25 |
| | 695907 and 695908 might be simple? | 12:06.23 |
| | but yes, I can't see anything immediately in there. | 12:06.29 |
| chrisl | tor8: it might be worth mentioning in the README that the new GL based viewer also needs: libxcursor-dev, libxrandr-dev and libxinerama-dev | 12:17.23 |
| tor8 | chrisl: hm, are those part of xorg-dev? | 12:23.33 |
| chrisl | tor8: they don't appear to be - I had to install them separately on Ubuntu 15.04 | 12:24.18 |
| tor8 | chrisl: right. I'll add those to the list. | 12:25.21 |
| | Robin_Watts: yeah, but I was planning on leaving those to sebras for when he inevitably gets bored of his work :) | 12:28.02 |
| Robin_Watts | henrys: welcome back. | 13:12.24 |
| | I guess you survived. | 13:12.33 |
| kens | start = copy + 2;Henry can always run :-) | 13:12.53 |
| henrys | good to be home. Yes it was only 1/2 time in flint then Quebec city - no crime there. | 13:13.11 |
| | catching up with everything this morning | 13:15.53 |
| kens | That'll take a while.... | 13:16.04 |
| henrys | just got a new computer so it won't take long ;-) | 13:19.56 |
| Robin_Watts | henrys: ooh, yours arrived too. Nice. | 13:20.33 |
| paulgardiner | hi henrys | 13:21.24 |
| henrys | the ghostscript compile went from 1 1/2 minutes to 30 sec. I still want parallel autoconf ;-) | 13:21.31 |
| | of course my old machine was dated | 13:21.48 |
| | paulgardiner: howdy | 13:22.10 |
| | and a new phone I'm overwhelmed with new gadgets | 13:22.28 |
| chrisl | parallel autoconf is technically not possible :-( | 13:22.51 |
| henrys | chrisl: I was joking, but I'd think some parts of it could done simultaneously. | 13:24.31 |
| chrisl | henrys: the problem is that it's all a shell script. To do something parallel we'd have to split it into multiple scripts - don't want to think about that! | 13:25.25 |
| | henrys: 'Course, if you used shared libs, configure would take about half the time...... | 13:26.52 |
| | henrys: Even running the libtiff configure in parallel only saves us ~2 seconds (from 9.2 to 7.3 seconds on my machine). Doesn't seem worth it. | 13:35.28 |
| henrys | chrisl: I meant that I wanted the autoconf folks to do it ... it's been recommended many times but there isn't much pressure to do it since configuring is usually less freqent and shorter than compiles | 13:39.06 |
| chrisl | henrys: I suspect the reason it's not been done is not lack of pressure, but lack of viability. | 13:41.00 |
| henrys | kens: I'm having difficulty understanding why the icc profile was set 2x, the language just sets whatever is in the pjl environment it should never set anything from the default environment. | 13:51.03 |
| Robin_Watts | In order to know whether a machine was powerful enough that you could realistically parallelise the configure stage, you'd need to configure it. So... metaautoconf :) | 13:51.29 |
| kens | henrys, I can't have some pdfmarks executed twice | 13:52.57 |
| | and if I put them in the PJL as a default, that's what happens | 13:53.13 |
| henrys | 2x per job or 2x per multiple jobs? | 13:55.46 |
| kens | 2x per jpb I think | 13:56.25 |
| | But I was only running one | 13:56.31 |
| henrys | kens: what happens in gs with -dJOBSERVER with ^D separating 2 postscript files? I think that is the analogous situation.. no? | 14:02.59 |
| kens | No because its not rerunning the code | 14:03.17 |
| henrys | kens: to my way of thinking separate jobs should have separate pdfs, unless you are specifically trying to concatenate stuff. | 14:06.01 |
| kens | People do that, yes, but also its because for one job we get 2 calls to do_reset which means we get doubled pdfmarks | 14:06.49 |
| henrys | do_reset in pcl? | 14:07.23 |
| kens | Yes | 14:07.27 |
| henrys | That's easily fixed in the language by only setting with a particular reset type as is done with many options. | 14:08.17 |
| kens | Hmmm, how do I know what ot use ? | 14:08.43 |
| henrys | well for exampe if you look at pcjob_do_reset - there is pcl_reset_initial and pcl_reset_printer etc. the pcl_reset_printer will be done each time there is a ^E a new job, pcl_reset_initial or pcl_reset_cold will work. But generally I fear you've stumbled on something that is really broken between pcl and pdfwrite statewise. Not sure there is been much testing at all with PJL and pdfwrite | 14:14.34 |
| | pcl_reset_cold is supposed to be power-up | 14:14.59 |
| kens | I'll have to think on it | 14:15.12 |
| henrys | kens: for now your setting can be conditioned on reset_cold or initial and it will only go once. | 14:16.05 |
| | "exclusive or" | 14:16.23 |
| kens | OK I'll try that i n a bit | 14:16.25 |
| henrys | Robin_Watts: I can finally have 3 monitors ;-) | 14:18.48 |
| kens | I have stuff pulled apart at the moment, I'll give it a go when it all compiles again | 14:18.58 |
| Robin_Watts | henrys: I bought my third monitor last week. | 14:25.56 |
| | I have now thrown my back out, which I don't think is related to the amount I now have to spin my head. | 14:26.16 |
| henrys | Robin_Watts: running? | 14:26.46 |
| Robin_Watts | henrys: I really don't know what caused it. It really hit me while I was doing my teeth one morning. | 14:27.20 |
| | but I don't think that was the cause. | 14:27.36 |
| chrisl | Robin_Watts: When I have back problems, it's usually a cough or a sneeze that triggers it - or something equally innocuous | 14:30.29 |
| Robin_Watts | chrisl: I think with back problems you can often hurt it, and your muscles keep it in check for a while. | 14:31.16 |
| | Then suddenly they have enough (or you sneeze etc) and they go "that's it. I've had enough. Feel the pain!" | 14:31.41 |
| chrisl | So far (touch wood!) I've only ever suffered muscular problems with my back, nothing spinal | 14:32.16 |
| Robin_Watts | henrys: Can we have a word on skype when it's convenient? | 14:36.40 |
| sebras | tor8: oh... I think I need to look at a few bugs apparently. | 14:45.03 |
| rayjj | henrys: we had a free user ask us about supporting OXPS with Ghostscript, and then (just a few days later) customer 870 asked about it. I put the customer # on bug 696272 but we probably should have someone respond to the cust. Marcos? | 15:01.51 |
| | henrys: and then figure out if this stays with Tor, or gets moved to someone else. | 15:02.27 |
| | Robin_Watts: I put in the initial part allowing for the alternate schema, but that wasn't enough by itself, but thanks for the suggestion | 15:03.37 |
| Robin_Watts | rayjj: Ah... hold on... I wonder... | 15:04.10 |
| | http://git.ghostscript.com/?p=mupdf.git;a=commitdiff;h=b6519f17 | 15:06.52 |
| | That's the MuPDF commit that changed stuff. | 15:07.05 |
| | looks like it needs to look for .oxps as well as .xps ? | 15:07.27 |
| chrisl | I'd be surprised if gxps paid attention to file name extensions | 15:09.19 |
| Robin_Watts | yeah. | 15:10.20 |
| | There are 2 schema things that need to be changed. I wonder if rayjj did both? | 15:10.38 |
| henrys | rayjj: thanks I saw that and promptly forgot about it not one of our more important customers | 15:11.16 |
| mvrhel_laptop | I can't remember all the diffs between oxps and xps. I was on the oxps committee for about a year. I think they did away with the windows hd image format and went with jpegxr if I recall. Also the whole windows color system stuff went away, thank goodness | 15:14.06 |
| chrisl | Seems there's been a bit more divergence between the muxps and the gxps implementations than might be considered "ideal".... :-( | 15:16.22 |
| henrys | they still have learned nothing about compatibility. Just stupid, convince folks to use pdf. | 15:21.43 |
| kens | Sadly XPS is the printing format in Windows | 15:22.20 |
| henrys | well I'll put it on the project list, that sucks | 15:24.32 |
| simon91 | Robin_Watts: tor8: you still here? Postet my fix: http://bugs.ghostscript.com/show_bug.cgi?id=696260. | 15:43.37 |
| Robin_Watts | simon91: I am still here, but I'm busy on non MuPDF stuff. That would be for tor8 to look at. He may possibly have gone for the evening. | 15:44.28 |
| simon91 | Robin_Watts: Ok. Will try to get in touch with him tomorrow | 15:45.13 |
| Robin_Watts | simon91: He reads the logs in general, so may well see this discussion. | 15:45.36 |
| simon91 | Robin_Watts: tor8: signatures of documents created with pdf_create_document seems to be broken since paulgardiner's patches to support multiple signatures. will write a report. | 15:47.12 |
| paulgardiner | Oops! | 15:47.45 |
| simon91 | paulgardiner: Hi! | 15:48.10 |
| paulgardiner | Hi simon91 | 15:48.45 |
| simon91 | Robin_Watts: when are you going to release? | 15:49.18 |
| Robin_Watts | simon91: tor8 was talking about doing an RC earlier today. | 15:49.47 |
| simon91 | paulgardiner: Robin_Watts: I don't think it will take mutch to fix the signatures. I'm still not having mutch to do at university this week, so maybe I have a fix till tomorrow. | 15:52.45 |
| Robin_Watts | simon91: Cool, thanks. | 15:52.57 |
| paulgardiner | simon91: yeah great | 15:53.36 |
| simon91 | Robin_Watts: paulgardiner: most of this PKCS7 and PKCS12 openssl API is pretty undocumented. pretty insane. | 15:54.32 |
| paulgardiner | It's a nightmare | 15:56.01 |
| simon91 | paulgardiner: did you write the stuff in pdf-pkcs7.c. Tor once said "it's paulgardiner area of code" ;-) | 15:57.04 |
| Robin_Watts | paulgardiner did the forms work. That included digital signatures. So, yes :) | 15:57.41 |
| mvrhel_laptop | I was just working on getting digital signatures working for gsview last week. need to do a bit more work. | 15:58.59 |
| | had not looked at the multiple signature issue yet | 15:59.25 |
| simon91 | paulgardiner: Robin_Watts: most of the signature stuff is written in a "(void) fread ... (void) fz_ftell" fashion. Think we should bail out as soon as possible on read error. But that's nitpicking. maybe i put it into a separate patch. | 16:00.38 |
| kens | OK goodnight all | 16:16.14 |
| jfkw | mupdf question: is there a way to pass config options e.g. ~/.mupdfrc to mupdf on open? I always hit "H" to fit page vertically as soon as mupdf opens, and would like to automate that. | 19:26.44 |
| | Withdrawn, I see http://bugs.ghostscript.com/show_bug.cgi?id=694785, would accept patch | 19:28.48 |
| mvrhel_laptop | lunch | 19:35.13 |
| cryptopsy | can i change the background of a pdf ? | 19:42.39 |
| | i would like to then invert its colors (white text become white, backround inverted too) | 19:43.02 |
| sebras | cryptopsy: if you are using the x11-based mupdf viewer, press "i". | 19:47.22 |
| cryptopsy | that inverts the color in the viewer but i would like to save it | 19:50.25 |
| sebras | cryptopsy: there's the -I flag for mutool draw for that. | 19:59.20 |
| cryptopsy | thanks | 19:59.28 |
| | can't figure out the syntax mudraw -I file.pdf -o out.pdf | 20:02.02 |
| | alos tried putting -I at the end | 20:02.06 |
| | mudraw -I -o lel.pdf 01-mediastinum.pdf , also didn't work but this syntax was from a blog showing how to use it | 20:04.36 |
| | gives a bunch of errors that it cannot open lel.pdf or load it | 20:05.00 |
| Robin_Watts | cryptopsy: You cannot change a PDF permanently in that way with mupdf. | 20:19.24 |
| cryptopsy | what about with mudraw? | 20:25.22 |
| sebras | cryptopsy: mudraw is just a command-line tool that uses the mupdf library. | 20:25.43 |
| | cryptopsy: what you can do is use mudraw to render to a bitmap and have the colors inverted. this is what -I is for. | 20:26.08 |
| cryptopsy | sure sounds great, can't figure out the syntax though | 20:26.53 |
| henrys | I knew I'd commit that debug code eventually ... sorry | 23:10.18 |
