NewIO hi, i'm new develop app for iOS, how to integrate MuPDF with iOS project 09:29.35 
  help me, plz!09:32.10 
Robin_Watts NewIO: Are you aware of the license terms for MuPDF?09:34.46 
  Specifically that it is released under 2 licenses.09:34.59 
  The first one is the GNU AGPL. This is a license that says that as long as you follow the rules, you can use MuPDF for free. These rules include (but are not limited to) the fact that you must be prepared to give away the source for your entire app to anyone that gets a copy of the your app.09:36.37 
  This license is, I believe, incompatible with the Apple App Store.09:36.57 
  The alternative is the Artifex commercial license. This frees you from the strictures of the AGPL, but will cost you money.09:37.50 
NewIO i'm know, but i'm fail to reference it to my project09:38.25 
Robin_Watts Sorry, I didn't understand that.09:40.51 
NewIO With android have guide: How to build MuPDF for Android. why haven't guide for iOS 09:40.59 
  sorry my bad english.09:41.15 
Robin_Watts NewIO: So you understand the licensing, but are still interested in integrating MuPDF into your app? So you are going to get a commercial license?09:42.22 
kens THat new bug report works fine (on Windows) using current code and the ps2write device. Of coruse ps2write doesn't work the same way as the old pswrite device. But since its Oracle and we know they tell people to use GS for producing PDF files as part of their reporting system (and have the cheek to label it a feature, or did) I'm not inclined to help them at all.09:50.56 
Robin_Watts reboots.09:55.58 
  Is bugzilla down for anyone else?10:45.11 
kens Was OK a moment ago, just a sec10:45.21 
  Well its just spinning now10:45.42 
  But I've had that happen often enough before10:45.53 
  It does seem pretty dead, got a timeout this time10:46.27 
  I see lots of machiens down on the cluster10:48.06 
  Maybe Marcos' garage is out ?10:48.14 
Robin_Watts Yeah. I'll cope.10:48.32 
kens Bugzilla seems to be back again Robin_Watts12:00.46 
henrys ugh oracle where are the scruples? Billion dollar company can't pay a support contract of a few thousand. We'll get scott on them again just to see what they say.12:54.28 
kens Nothing I imagine12:54.40 
  Its possible they may run into alignement isues on Solaris, if they're on a Sparc, I dont remember if they said what hardware it was12:55.35 
Robin_Watts kens was way too helpful on the bug.12:55.46 
kens I suppose I shouldn't have told them to try current code :-(12:56.02 
  Hmm htey have 'PC' as hte hardware which suggest x8612:56.54 
  But in that case, I can't see why pswrite would have thrown the error they report12:57.08 
  It 'looks like' an alignment error in the image interpolation code, but I wouldn't expect x86 to have an alignement problem12:58.15 
Robin_Watts I thought they said it was sparc.13:05.11 
kens Oh I was looking at the bug fields13:05.23 
Robin_Watts oh, they said solaris 10u1113:05.33 
kens Right.13:05.39 
Robin_Watts I bet they just reported it from a PC.13:05.57 
kens Almost certainly true.13:06.05 
  WHich was why I was a bit hesitant about what they might be running it on13:06.18 
  I still suspect ts an alignment problem13:06.33 
Robin_Watts I think we should actively ignore any problem from Oracle until they get a support contract.13:06.49 
kens If anyone is really interested we could ask Chris to run it on his Sparc13:06.51 
  Robin_Watts : yes you're probably right13:07.02 
  We already do that with BAE13:07.12 
ray_phone morning, all13:13.28 
kens Morning ray, why on a phone ?13:13.37 
ray_phone my laptop isn't handy atm13:17.47 
henrys yes please don't help them at all until Miles and Scott have had a go with them.13:36.15 
rayjj we should have a 'wall of shame' on our website (for companies like them) ;-)14:12.56 
Robin_Watts rayjj: Freeloaders of the month.14:13.20 
rayjj Robin_Watts: they've been at it for 10+ years14:13.36 
  scott probably has email archives of the first time he tried to get them on at least a support contract14:14.26 
  hopefully, the problem they found is still there in 9.16 ;-)14:17.37 
kens Can't be, they were using pswrite14:17.53 
  Though that doesn't preclude a similar problem14:18.23 
rayjj yeah, but ps2write probably doesn't perform the interpolaton -- just sets the /Interpolate true in the image in the output14:19.25 
kens Yes, I'm all but certain that's the case14:19.43 
rayjj why are they doing ps2ps anyway ? Seems rather pointless unless they were 'santizing' some PS from some driver into something 'generic' like pswrite creates14:21.19 
kens I suspect they weren't. Note that he tal;ks about reproducing a problem 'without printing' or something like that14:21.49 
  "reproduce the issue without the need to configure printing:"14:23.21 
henrys fredross-perry: not sure if you know after the irc meeting we have a smart office meeting at 8am on skype14:24.52 
fredross-perry thanks, i’ll head there after14:25.15 
rayjj has fredross-perry been sucked into the SOT black hole ?14:25.34 
fredross-perry more of a vortex, really.14:25.55 
rayjj going around in increasingly small circles :-)14:26.32 
henrys meeting item 1 - 17 customer bugs in the report - we need to do some bookkeeping ;-)14:27.54 
chrisl kens: alignment problems on SPARC trigger a bus error, not a seg fault14:28.03 
kens chrisl AH, OK so not that then :-)14:28.18 
chrisl henrys: I'm probably about to close one14:28.35 
Robin_Watts only 13 if you ignore the SO ones.14:29.06 
henrys I'm marching through them now ...14:29.15 
kens One of mine is actually from Marcos, another is old and a final one has a work-around14:30.01 
henrys fredross-perry: will you be at the upcoming meeting?14:30.02 
fredross-perry yes I will14:30.15 
henrys fredross-perry: nice it'll be good to meet you14:30.31 
fredross-perry xclnt14:30.38 
  it’ll be nice to put faces to names14:30.53 
Robin_Watts kens: bug 695978 smells like "downsampling is defaulting to mitchell rather than off".14:31.11 
  fredross-perry: Wait til you've seen our faces...14:31.27 
fredross-perry ;-)14:31.53 
kens Robin_Watts : marcos claims its running a downsample filter when it should not be14:31.53 
  As far as I cna tell, it isn't but I've not tried it14:32.08 
Robin_Watts That would seem to fit with the timings, yes.14:32.09 
henrys chrisl: I've been looking at fonts this week with respect to the shared language, it looks like with a few exceptions we will have coverage for PCL using the new type2 fonts , but did you check urw's work against your list (ufst vs urw)?14:32.15 
chrisl henrys: I did not14:32.48 
kens Robin_Watts : there is a problem whre two tests are out of step, and we cna end up applying bicubic in one case where we should use average, but that's a different thing altogether14:33.00 
henrys chrisl: I'll go ahead and check that I've written scripts and stuff to get at all the glyphs in the fonts already, it'll be easy to xref your list.14:33.38 
chrisl henrys: Okay, thanks.14:34.11 
kens Robin_Watts : my current cluster run is good (I finally realised the diffs I was seeing were to due to Michael's last commit) so I'll stop and take a look at some of mine, especially the bicubic things14:34.30 
chrisl henrys: TBH, I thought you'd decided to go with compatibility with the MS fonts (to match Acrobat) rather than UFST....14:34.49 
mvrhel_laptop yes. there were a lot of color changes with the transparency group color space change14:35.40 
kens mvrhel_laptop : it only affected 2 test files for me :-)14:35.52 
henrys chrisl: I don't see a good route to MS compatibility if you mean CJK.14:35.59 
mvrhel_laptop in most cases it is very hard to tell the diff. 14:36.01 
  needs to be an odd blend mode14:36.08 
  to really notice14:36.14 
chrisl henrys: Not CJK, no14:36.29 
kens One of them was impossible to see (resulted in a halftone difference only) in the other case a black was coming out as CMYK14:36.30 
henrys chrisl: and we did give urw the the list we should check they did what we paid for. right?14:36.46 
chrisl We should, yes. I just wasn't entirely sure what list we'd paid for.....14:37.08 
kens mvrhel_laptop : I spent about an hour scratching my head before light finally dawned....14:37.09 
mvrhel_laptop sorry about that kens14:37.30 
kens mvrhel_laptop : My fault, not yours14:37.44 
  I should have thought of it earlier.14:37.51 
henrys mvrhel_laptop: I guess the certificates are stalled I'll check with Joann after the meeting again.14:37.57 
kens marcosw did you add and then remove a couple of test files ?14:38.08 
mvrhel_laptop henrys: ok14:38.09 
Robin_Watts henrys: The certificates are stalled, yes.14:38.23 
  Something went wrong in the ordering process, and Comodo are cancelling them.14:38.39 
marcosw kens: yes14:38.45 
Robin_Watts We have to wait about 3 days for that to happen, then Joann will start again.14:38.56 
kens aha, that explains my odd results then, they were causing the 'Internal error' messages ?14:39.04 
henrys Robin_Watts: oh okay are you handling that, if so I'll not bug Joann14:39.09 
rayjj henrys: wouldn't it be better to not have Joann in the loop on the certs ?14:39.24 
Robin_Watts henrys: Joann is handling it - she's just keeping me up to date with what is going on.14:39.30 
  rayjj: The certs require various things that made it look like it would be easiest for joann to handle them.14:39.58 
  a) they are a subscription basically, b) they need the company number and DUNS number etc, c) they need to do various identity checks on the company for validity.14:40.27 
rayjj Robin_Watts: henrys: just seems like not her 'cup of tea' and drifting14:40.37 
Robin_Watts To be fair, the website is bloody confusing.14:40.56 
henrys I was going to bring up language switching but the bug report kind of knocked me over. We really need to get this number down.14:44.23 
chrisl There you go, reduced by one......14:45.28 
mvrhel_laptop henrys: I should have 695930 done this week. fixed the big issue14:45.57 
henrys are we really ever going to fix the 256 color thing?14:45.59 
rayjj Robin_Watts: (anybody) are we getting VS 2015 Community ed?14:46.03 
Robin_Watts rayjj: VS 2015 community edition is a free download.14:46.19 
mvrhel_laptop there is one little area that has an lab color and an odd blend mode that is different then Acrobat14:46.22 
Robin_Watts or rather, it will be when it comes out.14:46.27 
  VS 2015 RC is out now.14:46.34 
mvrhel_laptop henrys: I have not had a chance to look at the 256 color bug14:46.41 
  I want to14:46.43 
Robin_Watts The full release will (going by previous timings) be another month or so.14:46.46 
rayjj Robin_Watts: OK. my VS 2013 trial expired, so I'm uninstalling it. I want to try the profiling tools of VS 2015 on the performance bug 695568 (to get that off my list)14:47.27 
henrys Robin_Watts: and the apple certs?14:47.41 
Robin_Watts henrys: No idea about the apple certs.14:47.56 
mvrhel_laptop henrys: it is likely that 695927 will be fixed with these transparency fixes also14:48.14 
Robin_Watts rayjj: I'd download the RC and give it a spin. bandwidth is cheap, right? :)14:48.42 
marcosw mvrhel_laptop: could you look at 695964? it's a regression that caused about 200 output files to change and is affecting nightly/weekly regression testing.14:48.45 
henrys okay and we are going to clear the ghostdocs - nice to see a single digit for the total bugs.14:48.53 
Robin_Watts henrys: Are we?14:49.02 
henrys I thought they could go in the enhancement bin vs defect no?14:50.14 
mvrhel_laptop marcosw: hmmm are you sure these are regressions?14:50.18 
Robin_Watts henrys: yes, probably.14:50.22 
mvrhel_laptop all I did was turn off the simulated overprinting14:50.42 
  pkmraw should still show overprinting for cmyk14:51.13 
  the pam device will not show overprinting14:51.20 
  so the two can differ14:51.29 
henrys mvrhel_laptop: I'm concerned you are a bit overburdened bug wise can someone else help out with something?14:51.42 
  anybody else have meeting business? I don't have anything more.14:52.25 
fredross-perry i’m good14:52.46 
mvrhel_laptop the one customer that wants someone to look at his project. who is going to do that? I think it is a c++/c# project but I have not looked at it14:53.28 
Robin_Watts mvrhel_laptop: Jung ?14:53.46 
mvrhel_laptop yes14:53.50 
Robin_Watts It is a C# project, but I don't believe it's complete.14:54.05 
  Certainly I can't see the mupdf lib in there.14:54.17 
mvrhel_laptop In the past when I have looked at his stuff it was pretty basic mistakes that he has made but it takes time and seems out of scope from a support end to me14:54.22 
Robin_Watts it requires VS > 2010, so I can't look yet.14:54.36 
mvrhel_laptop I can look at it maybe next week 14:54.57 
  I want to get these transparency bugs done first14:55.06 
marcosw mvrhel_laptop: I think so, there are large bits of the output missing for some of them.14:55.08 
Robin_Watts mvrhel_laptop: I've gone back to him with a request for a complete project with step by step build instructions.14:55.13 
mvrhel_laptop ok good14:55.34 
Robin_Watts if he provides that, we'll worry about it, otherwise I vote we make him wait.14:55.41 
mvrhel_laptop marcosw: can you list the file locations for a couple of them14:55.50 
  on the bug14:55.52 
  Robin_Watts: sounds good to me14:56.03 
marcosw mvrhel_laptop: sure, I'll add it to the bug report14:56.20 
mvrhel_laptop thanks. I will check it out14:56.36 
henrys I'm good with that, even if he does give us details it's a bit out of our ken 14:56.49 
  off to skypeland14:57.53 
rayjj mvrhel_laptop: for gsview, do I need silverlight and/or MFC for C++ (installing the VS 2015 RC)15:09.18 
mvrhel_laptop rayjj: no you don't need silverlight15:10.15 
  when you install it should install the proper update of .net if you don't have it15:10.33 
  no MFC either15:10.43 
  rayjj: oh you are talking about VS install15:11.06 
chrisl kens: note that I just updated freetype, so you'll get a bunch of diffs compared to master until you rebase again15:11.08 
kens marcosw can you attach rthe PCL file to bug 695978 please ? I can't find the source any more15:11.15 
rayjj mvrhel_laptop: right15:11.19 
kens chrisl I noticed you;d done that :-)15:11.24 
mvrhel_laptop rayjj: no silverlight or MFC15:11.31 
rayjj I'm installing their github (I hope it doesn't confuse my msysgit)15:12.39 
Robin_Watts rayjj: Shouldn't do.15:12.59 
mvrhel_laptop I have no problems with it15:13.28 
rayjj Robin_Watts: yeah, but with MS, you can never be sure. They manage to screw up in surprising ways15:13.35 
  mvrhel_laptop: are you using VS 2015 Community or still back at VS 2013 ?15:14.02 
kens chrisl thanks for the bisect, I confess to some surprise :-)15:14.19 
mvrhel_laptop I am still using 2013. I will go to 2015 when it is released15:14.21 
  not a big fan of RCs15:14.35 
chrisl kens: I had a feeling it would be transparency related15:14.45 
kens Yes, just surprised its clist and patterns15:15.03 
chrisl <shrug> I'm only reporting what git told me :-)15:15.28 
kens :-)15:15.33 
rayjj ha ha. VS 2015 is version 14 (I wonder what the _MSC_VER will be)15:15.45 
kens THat's one more of Michael's list though15:15.46 
mvrhel_laptop kens what bug is this?15:28.40 
kens THe on Chris just assigned to Ray15:28.54 
  69597515:29.07 
mvrhel_laptop ok15:29.41 
chrisl mvrhel_laptop: don't you get the bug status e-mails?15:31.02 
mvrhel_laptop chrisl: i do. I missed that one15:36.46 
Guest_____ Hi all. My name is Gustavo, from Argentina, I would like to ask for your help with an issue that we have with Ghostscript15:45.17 
Robin_Watts Guest_____: Ask away. (on IRC, always ask, don't ask to ask)15:45.40 
Guest_____ Thanks, sorry15:46.11 
Robin_Watts no problem!15:46.22 
Guest_____ We need to complile the source code of Ghost PCL in a Solaris 9 under SPARC15:47.00 
  but always getting error 15:47.08 
Robin_Watts Guest_____: Are you using the latest version? 9.16?15:47.35 
henrys Guest_____: you need a gcc toolchain and gnumake15:48.24 
chrisl beaten to it by henrys 15:48.39 
Guest_____ let me confirm version, yes we are using gcc and gnumake15:48.45 
kens wonders why people are suddenly using Sparc/Soloaris so much15:48.55 
henrys Guest_____: report a bug with output we may have a look at it.15:49.28 
chrisl kens: Possibly because Oracle whacked out some new SPARCs last year, which are supposed to be seriously fast (for certain applications, anyway)15:50.32 
kens Ah, so its all back to Oracle again :-(15:50.47 
chrisl Well, they bought Sun, so.....15:51.13 
Guest_____ I our case, is not a choice, we are mantaining an old application that runs under it15:54.54 
mvrhel_laptop Robin_Watts: are you around?17:43.32 
Robin_Watts I am.17:46.35 
  Just to keep you in the loop, Jung has got back to me with a better project.17:47.11 
  he's making me one with all the source in at the moment, but I'll need a newer MSVC to build it - so am downloading the community edition RC now.17:47.43 
mvrhel_laptop Robin_Watts: ok18:11.53 
  I have the .net stuff reorganized for him18:12.05 
  Robin_Watts: what would be the best way to share this with him?18:12.22 
Robin_Watts A .zip file, I guess.18:12.36 
mvrhel_laptop ok. I will do that. 18:12.55 
Robin_Watts unless we want to give him access to the whole gsview source (which I'm sure we don't!)18:12.59 
mvrhel_laptop henrys: bug 695930 will be closed in a minute18:13.52 
  the last remaining difference that I had goes away when we use the output intent icc profile18:14.11 
henrys super mvrhel_laptop 18:14.12 
mvrhel_laptop then we match adobe 18:14.16 
rayjj chrisl: I closed bug 695975, since all I see is a very slight color difference, most likely due to the differences in the original file (which I'm not going to dig into for a free user)18:14.43 
chrisl rayjj: slight? I wouldn't call that slight, and the previous output (more closely) matches Acrobat18:16.26 
mvrhel_laptop rayjj: so 695930 is closed if you want to let the customer know what the situation is18:16.32 
  moving onto 69592718:16.53 
rayjj chrisl: when I open the a.pdf with mupdf it's totally wrong18:18.05 
  mvrhel_laptop: thanks for the update on that bug18:18.22 
mvrhel_laptop rayjj: so two things of interest with this altona file. 1) the non isolated transparency groups mean that the results will very depending if the output device is RGB or CMYK. 2) Adobe will use the output intent profile for default CMYK values. We need to use -dUsePDFX3Profile to get a similar result18:20.04 
  s/very/vary/18:20.28 
  but they do need to get the one fix that I committed18:20.44 
rayjj chrisl: it doesn't even say which one is supposed to be correct the one from the .ai file or the one from the .pdf file18:21.54 
chrisl rayjj: he says *both* have changed - he's using gs to render ai as well as PDF18:22.54 
mvrhel_laptop and page 4 matches adobe when I do -dUsePDFX3Profile 18:24.48 
rayjj chrisl: I wasn't comparing to acrobat -- we rarely match their colors18:25.20 
mvrhel_laptop hmmm18:25.26 
  don't know if I agree with that statement18:25.34 
chrisl rayjj: this isn't subtle, I would say18:25.37 
rayjj chrisl: have you looked at it with mupdf -- that's *really* wrong. I'll have a look at the colors/patterns etc. (re-opening) but I'm not sure how my commit would affect it since I see the same thing with -dMaxPatternBitmap=1g (so it doesn't use the pattern-clist)18:28.35 
chrisl rayjj: Well, mupdf getting it wrong isn't a reason for us to ignore it..... and I implied above that I was a little sceptical about the git bisect result....18:29.39 
rayjj kens: (for the logs, I guess) you mentioned that mupdf looks like Acrobat. I may have an out of date mupdf (I'lll check) but AFAICT mupdf doesn't have a way to display its version :-(18:31.17 
  and my mupdf is totally wrong (just flat light yellow)18:31.38 
  bbiab...18:31.48 
chrisl rayjj: FTR, here's what I'm seeing http://ghostscript.com/~chrisl/both.jpg (I wouldn't call it a 'slight' color change)18:33.20 
rayjj_ hmm... I just installed mupdf 1.7a and it looks wrong. Can someone else try displaying a.pdf from bug 695975 with 1.7a18:36.43 
chrisl rayjj: the color difference is gs 9.15 vs 9.1618:42.41 
  rayjj: see http://ghostscript.com/~chrisl/both.jpg18:42.51 
mvrhel_laptop ok. so page 4 looks good compared to Acrobat18:44.50 
chrisl rayjj: yes, current mupdf looks very, very wrong with a.pdf18:44.55 
  rayjj: mudraw says "warning: ignoring transfer function , warning: ... repeated 2 times ..."18:46.27 
henrys my os x font book is screwed up I can install fonts and can use them in apps but they don't show up in font book. Googling leads me to believe I'm just stuck in a dark corner of the universe.18:49.03 
kens ray_phone : chrisl yes MuPDF is incorrect, bnut its not the transfer functions, I removed those and it made no difference to any viewer.18:54.13 
mvrhel_laptop rayjj 695927 is also closed. 18:54.26 
kens Both transfer functions are a simple inversion, so I'm surprised not to see a difference....18:55.12 
chrisl kens: I didn't look any further,,,,18:55.23 
kens The file is, of course, overly complex.18:55.45 
  and pretty much *everything* has transparency applied to it.18:56.40 
rayjj chrisl: I wonder how mupdf used to get it right ?18:56.53 
kens ray_phone : I don't thnk it did18:57.04 
  I htnk I used 'another PDF consumer' and thought I'd used MuPDF18:57.22 
rayjj kens: OK. I was going by the comment in the bug18:59.02 
kens >Yeah my error there18:59.51 
kens is off again, will read logs in a bit19:00.19 
chrisl rayjj: the important thing is that there has been a significant change in the rendering of the PDF somewhere between 9.14 and 9.1619:00.28 
rayjj chrisl: OK, but we need to understand which is correct, and why19:00.54 
chrisl Well, we usually take Acrobat as the benchmark....19:01.18 
rayjj yeah, but which version :-)19:01.38 
kens I presume they want it to match Illustrator19:01.49 
  and it did before19:01.54 
chrisl rayjj: Acrobat 9's output: http://ghostscript.com/~chrisl/a-acro9.jpg19:03.48 
  That looks very much like the old Ghostscript output19:04.25 
mvrhel_laptop marcosw: so tests_private/comparefiles/Bug689880.pdf should be radically different with the change that we did. AR show very little output with overprint turned off19:04.31 
  it is going to be quite different between the RGB and CMYK devices19:05.14 
  I will look at the others19:05.28 
  hehe tests_private/comparefiles/Bug691001.pdf is the same19:06.16 
  with overprint off the output disappears with Acrobat19:06.26 
  and tests_private/comparefiles/Bug691002.pdf19:07.30 
  marcosw: ok I took care of 695964 for you ;)19:09.59 
  rayjj: I thought I gave you 69592919:10.21 
  this had to do with our generation of the screens19:11.24 
henrys wow libre office draw is a pdf editor too, lots of problems of course, but not bad21:17.14
