kens chrisl_t530 : I may have a solution to the 'font outlines' thing08:00.58 
chrisl_t530 kens: Oh, I may do, too......08:01.15 
kens Mine's in pdfwrite :-)08:01.23 
chrisl_t530 So's mine.....08:01.30 
kens ROFL, OK how are you approaching it ?08:01.45 
chrisl_t530 If we skip creating pdfwrite's own enumerator for the show operation, and disable the cache, pdfwrite just gets marking operations, and has no clue where they came from08:02.26 
kens OK I'm doing it differently. If I set the font->dir->ccache.upper to 0 then we don't cache the font (I save the upper limit so I can replace it). THis causes us to draw paths, which are captured in teh content stream, not the font.08:03.33 
  Potentially this will in the future allow me to capture type 3 fonts with outlines instead of bitmaps, for the 'fallback' cases.08:04.10 
chrisl_t530 Hmm, really? I wonder why using -dNOCACHE doesn't work, then08:04.18 
kens chrisl_t530 : because we don't usually bitmap characters at all. So in general we don;t ever use the cache08:04.45 
chrisl_t530 Yeh, but all -dNOCACHE does is set font->dir->ccache.upper to 008:05.18 
kens In this case, to make it work for all fonts, I will add a new device parameter which will force all fonts through the fallback route, and also will disable the cache.08:05.18 
  chrisl_t530 : Yes but most fonts never go there08:05.30 
  THe second part is to force all fonts to go through the fallback so they try to bitmap08:05.48 
chrisl_t530 Hmm, I think we're doing the same thing in different ways.....08:06.28 
kens Probably, but I like my way better :-)08:06.38 
chrisl_t530 My way doesn't require any new options08:06.57 
kens Because in the future I can use it to capture outlines for fallback fonts, without disturbing cases which we do handle08:06.57 
  chrisl_t530 : Yeah, but I want it as a new option. I want it to be very explicit about what's going on. One of the problems with the pswrite thread is people using the 'feature' which was never a feature at all. THIs way it really is.08:07.47 
chrisl_t530 So, where do you force the "fallback" case to happen?08:08.08 
kens In pdf_text_process08:08.29 
  line 3473 I just skip over the processing and jump straight to 'default'08:08.54 
  default_impl that is08:09.18 
chrisl_t530 Okay, well, I'm happy with either - I was hoping to put together a Postscript based solution, but I can't see that working.....08:09.37 
kens I saw the comments about it, but I wasn't happy with that, its too fragile. And it wouldn't work with XPS or PCL08:10.09 
chrisl_t530 Well, I think ps2write/pdfwrite will preserve the "charpath" as a tr mode, won't it?08:11.10 
kens Yes it will08:11.18 
  Well, it tries to anyway08:11.26 
chrisl_t530 And using pathforall to "hide" the charpath won't (or shouldn't) work on certain fonts08:11.55 
kens OK I'm going to cluster test this, then I'll figure out a new switch08:12.04 
  chrisl_t530 : it certainly *shouldn't* work :-)08:12.25 
  THis test is going to produce a bazillionlittle diffs :-(08:12.54 
chrisl_t530 I cluster test my solution (forcing it through the "flatten fonts" case), and I was surprised there were only about 1k tests with differences - I really thought it would affect almost all08:13.27 
kens I'm forcing the outlines for now as well. I'm expectin *many* diffs.08:13.54 
  It'll be interesting to see if we get similar results :-)08:14.33 
chrisl_t530 Like I say, I expected very nearly all pdfwrite/ps2write tests to show differences - a thousand or so test cases seemed too few08:14.52 
kens I'll let you know.....08:15.11 
  Or you cna just look at the dashboard as well08:15.25 
chrisl_t530 It will be interesting - I wondered if mine was missing cases, but it's hard to see how......08:15.58 
kens Two different approaches should cover the bases, if we get the same results, I guess we know we tested reasonably well08:19.22 
chrisl_t530 Well, I like handling where I did because I figured there was no chance of getting anything font like without going through gdev_pdf_text_begin().....08:20.15 
kens Ah but for later, I want to be able to do this without breaking all fonts08:20.34 
  Its a good step along the way to getting type 3 fonts that aren't bitmaps when we do have to fallback for weird fonts08:21.36 
chrisl_t530 That would be possible in gdev_pdf_text_begin() - but it doesn't matter. I was really only interested that, for once, pdfwrite didn't die horribly after a change like that08:21.51 
kens It did when I tried to force the accumulator to install and pick up the outlines :-(08:22.20 
  More work needed there I'mafraid08:22.32 
chrisl_t530 Yeh, that seemed overkill for this case08:22.53 
kens Oh sure, infact for this use its a bad idea, because we end up with fonts again. The only reason I'm looking at this is because of the cases where we end up rendering a bitmap type 3 font. I'd rather have an outline type 3 font. We've discussed it a few times08:23.45 
chrisl_t530 Yep. My motivation was that the guy did come through with a use case that sort of makes sense - although it is bonkers that those applications fail so miserably with an embedded font.08:25.53 
kens Its hardly our fault. I was also kind of miffed that they implied we shouldn't do anythign without consulting them and 'we've broken their software' when they were hacking on a device in the first place, and ignored teh (many, many) warnings we published about it being deprecated.08:27.22 
  But, I figured it would help me get to somewhere I wanted to go, if I could make it work.08:27.51 
  The thread was bizarre in many places " We had to switch to ps2write, but we've had problems with ps2write output before, and so I'm hoping that those problems were bugs and that the bugs have been fixed by now" And did you report those as bugs ? If he haqd he would know they'd been fixed, if he didn't, well.......08:29.23 
chrisl_t530 And "what about support for Level 1 printers" - REALLY????08:29.55 
kens Yeah, when was the last time someone made a level 1 printer ?08:30.11 
  Any that are still running must be working on hand-crafted consumables.....08:30.33 
chrisl_t530 And "portable Postcsript"? FFS do you know anything about the language?!?!08:31.21 
kens Clearly not, as I pointed out :-)08:31.30 
chrisl_t530 But as so often happens, if we show willing to help workaround a bug/limitation in someone else's software, it probably makes us look quite good08:32.26 
kens Nobody in the know believes level 1 PostScript is portable. But of course, if you get all your information from Wikipedia and other authoritative online sources.....08:32.35 
  Wow, lots of diffs08:33.03 
  And a huge pile of seg faults, which is unexpected08:33.19 
chrisl_t530 Ah, well I got no seg faults :-)08:33.37 
  And, like I said, I bet a *real* Level 1 printer couldn't actually handle the output from pswrite anyway08:34.12 
kens 9579 diffs in pdfwrite08:34.16 
  chrisl_t530 : Very possibly not08:34.26 
chrisl_t530 Well, considering the resource limits when Level 1 was current08:34.51 
kens Probably depends how many fonts you use08:35.12 
chrisl_t530 Images, shadings etc etc08:35.41 
kens Well I'd better look at these seg faults first I guess08:36.13 
  Umm, looks like I'm breaking type 3 fonts08:41.53 
chrisl_t530 Odd....08:42.28 
kens Yeah, the font pointer is NULL, which is quite bizarre.08:42.44 
  Maybe there's something I need to set up in text_process that I missed.08:43.02 
  AH, looks like I haven't created a type 3 font to populate08:46.05 
  Presumably that's done somewhere else, the usual crap of pdfwrite08:46.48 
chrisl_t530 I'm confused - that doesn't sound like you are degenerating glyphs into "bare" marking ops......08:46.58 
kens Its complicated.......08:47.11 
chrisl_t530 Isn't it always??08:47.23 
kens We take different code paths for type 3 fonts (input as type 3 fonts) through the charproc accumulator08:47.35 
  And it assumes we already have built a type 3 font to hold the result. Naturally this is created 'somewhere else'08:48.02 
chrisl_t530 Okay, I'll leave you to it - I have to make some phone calls.....08:48.34 
kens NP08:48.39 
  Its my code, and I'll need to solve this for the general case eventually08:48.52 
jogux gotta love appstore reviews: "Was great until update09:12.07 
  Now I can not open any .xlsx files. Very frustrating for working on the go. ".09:12.07 
kens Hmm, still some seg faults in PCL. lots of diffs in PS/PDF09:24.40 
  path+fill is bolder than font rendering it seems09:25.11 
chrisl_t530 I think we established that when we did the fapi stuff09:26.06 
kens Yeah, just an observation. Looks like I should fix PCL because I see a *lot* of diffs09:26.29 
  9961 of 14344 in pdfwrite09:27.01 
  5594 of 9558 in ps2write09:27.23 
chrisl_t530 I got Differences in 1463 of 14344 pdfwrite test(s):09:27.37 
  And Differences in 839 of 9558 ps2write test(s):09:28.02 
kens To be honest, mine is more like what I'd expect09:28.05 
chrisl_t530 Both of which I felt were oddly low....09:28.21 
kens Yes, I'd expect small differences on pretty much every page with text, which is most of them09:28.43 
  looks like a long task ahead, best I fix PCL first09:29.09 
chrisl_t530 Yeh, but like I said, I can't see how you get text without going through the enumerator creation09:29.18 
kens Beats me :-)09:29.27 
  If you like you could find a file where I see a diff and you don't, and then see what your fix produces in the way of a PDF file09:30.05 
  Given I have so many files with diffs, it shouldn't be hard to find one09:30.22 
chrisl_t530 Well, the problem is, my solution is one problem only - it's no help with your ultimate goal09:30.55 
kens True, but if you really want to know what's going on it might tell you09:31.26 
chrisl_t530 At the moment, I have two partially non-functional Ubuntu computers I could really do with fixing :-(09:32.03 
kens Seems like a better use of your time then. As I said, I *expected* a lot of diffs.09:32.28 
chrisl_t530 OTOH, if you'd like some help with your solution, I wouldn't mind pitching in09:33.16 
kens Up to you, I'm hacking on it at the moment, findong out all the places I need to skip over things to prevent cxrashes09:34.08 
  I think I've sorted PCL (hacky temporary solution), just need to test it first09:34.38 
chrisl_t530 You can let me know - I would *really* like my two main computers fully functional again!09:35.06 
kens Then I'd say go fix those, I'm progressing here, even if slowly09:35.33 
chrisl_t530 Trouble is, I've no clue what caused the problem - other that something in the recent updates :-(09:36.31 
kens :-(09:36.40 
  OK lets see if anything is still broken09:37.17 
  Yay, all seg faults sorted09:56.06 
  Now a mere 15000 diffs to compare.....09:56.27 
  Interesting, some PCL content is lighter when made into filled paths, whereas PostScript is bolder.10:23.54 
  Ah, its a lower resolution10:27.38 
zeniko tor8: Robin_Watts: (or FTL) there are 10 small bug fixes on zeniko/mupdf for review14:10.19 
tor8 Robin_Watts_: zenikos 10 fixes all LGTM, but you might want to give them a look as well before I push them?14:37.23 
Robin_Watts_ tor8: Nah, go for it. I'm buried at the mo.15:02.24 
rayjj morning, all15:38.22 
kens morning ray15:38.31 
rayjj got my son off to camp...15:38.35 
  hi, mvrhel_laptop15:38.42 
mvrhel_laptop morning rayjj15:38.54 
rayjj mvrhel_laptop: In case I get fed up with real work, I'd like to track down what I need to build gsview.15:39.28 
mvrhel_laptop rayjj: you should be able to build the main executable15:39.53 
rayjj mvrhel_laptop: after I was offline the other day you said I might be missing some "other" stuff15:39.54 
mvrhel_laptop only for the installer 15:40.05 
rayjj mvrhel_laptop: first, have you tried with VS 2013 Express (I started with that for now)15:40.37 
mvrhel_laptop rayjj: you wont be able to build some of the other projects since they are windows 8.1 applications15:40.38 
  rayjj: no I have VS2013 pro15:40.51 
  rayjj: but you should be able to build gsview15:41.21 
  as it is just dlls and the main gsview application15:41.41 
  which is a wpf c# project. that should def. build15:42.08 
rayjj mvrhel_laptop: first, what should I try in the confguration manager ? It defaulted to "Mixed Platforms". Maybe x64 or x32 ?15:42.34 
mvrhel_laptop it should be mixed15:42.57 
  for gsview15:43.07 
  hmm let me go there15:43.24 
  hold on15:43.27 
rayjj mvrhel_laptop: OK. Note that when I select "Mixed" it has Win32 for most parts and "Any CPU" for gsview15:44.19 
mvrhel_laptop hold on15:44.29 
  so I have x64 seet15:45.29 
  set15:45.31 
  which means all the libraries are built with x64 except for the c# wpf project which is built with anyCPU15:45.58 
rayjj mvrhel_laptop: the first Error I get is: Error1Application Configuration file "App.config" is invalid. Could not find file 'C:\Artifex\gsview\mupdf\platform\winrt\gsview\App.config'.C:\Artifex\gsview\mupdf\platform\winrt\gsview\App.configgsview15:46.07 
  then: Error2error C1083: Cannot open include file: 'mupdf/pdf-tools.h': No such file or directoryc:\artifex\gsview\mupdf\platform\winrt\mupdfwinrt\muctx.h111mupdfnet15:46.35 
mvrhel_laptop perhaps I did not get something checked in. rayjj: let me do a clean checkout later today ad make sure all is ok15:47.00 
  s/ad/and/15:47.06 
  rayjj: did you have a list of things that you found that needed to be fixed?15:47.50 
  I know I have a few things15:47.58 
rayjj mvrhel_laptop: BTW, what I have as the remote.origin is /home/mvrhel/repos/mupdf.git15:49.16 
mvrhel_laptop rayjj: yes15:49.33 
  and it is the win_desktop branch15:49.43 
rayjj morning, kens 15:49.43 
  (I just noticed -- sorry, kens)15:49.54 
  mvrhel_laptop: right, that's what I have in that directory15:50.27 
  mvrhel_laptop: can you see if you have App.config -- that's the first error message, and it shows up in the Solution Explorer15:55.03 
  mvrhel_laptop: maybe you forgot to git add it ?15:55.30 
  mvrhel_laptop: I started with just libmupdf and I get: Error1error C2065: 'pdf_font_DroidSansFallbackFull' : undeclared identifierc:\artifex\gsview\mupdf\source\pdf\pdf-fontfile.c1431libmupdf15:57.55 
mvrhel_laptop rayjj: ok. let me wrap up what I am doing in SOT for a sec15:58.43 
Robin_Watts_ rayjj: That smells like a generated issue.15:58.53 
mvrhel_laptop right15:59.14 
rayjj Robin_Watts_: that area is dependent on NOCJKFULL15:59.50 
Robin_Watts_ rayjj: There is a step in the build where we take the font files, and make header files with the data in.16:03.47 
  That's the 'make generated' step in unix terms.16:03.58 
  It's possible that the windows rt stuff assumes that you've done a normal windows build first to setup the generated dir.16:04.32 
rayjj Robin_Watts_: apparently that step isn't a precursor to libmupdf16:04.49 
mvrhel_laptop this whole thing is not really ready for others. the solution has both winrt projects and the gsview project. however you should be able to build gsview. 16:05.28 
rayjj Robin_Watts_: at least for the winrt platform, as you've said. I'll try building mupdf first then16:05.33 
mvrhel_laptop certainly you need to build mupdf16:05.44 
Robin_Watts_ rayjj: The generated step is a precursor to libmupdf on the normal VS project.16:06.24 
mvrhel_laptop it is here too16:06.31 
rayjj mvrhel_laptop: OK, you can go back to having fun with SOT -- I'll just play around with it, but the App.config does concern me16:06.40 
mvrhel_laptop let me stop what I am doing and work on this now16:06.42 
  rayjj: I think you need to come over to SOT 16:07.02 
rayjj ahhhhhhhhhh!!!!!16:07.19 
rayjj runs screaming16:07.25 
mvrhel_laptop hmm looks like the dependencies are not set up correctly. let me fix that first16:07.47 
rayjj So here I am, back working on ghostscript clist crashes. Whew! that was quite a nightmare where somebody mentioned that I should work on SOT.16:08.54 
  :-)16:09.01 
mvrhel_laptop :)16:09.12 
  rayjj: there are dependency issues in the project I can see16:09.35 
  let me try to fix those today as well as make sure all the files are there16:09.47 
  but I want to fix this one offset angle thing in SOT first16:10.44 
  for the pie charts16:10.48 
  it is a low hanging bug fix 16:10.56 
rayjj mvrhel_laptop: libmupdf had dependencies listed for generated, gsview, libthirdpary and mupdfnet, but none were checked by default. I checked all but gsview16:11.32 
mvrhel_laptop rayjj: will look at this in a bit 16:12.30 
  libmupdf is not dependent upon mupdfnet certainly16:13.13 
  anyway. let me wrap up this thing first16:13.39 
  SOT that is16:13.44 
kens goodnight folks.....16:22.41 
rayjj Robin_Watts_: It seems that 'clean generated' doesn't delete the generated files -- there was an almost empty one generated when I tried the winrt gsview build and when I did rebuild generated for win32 mupdf it didn't clean it out, so I had to manually delete it16:24.32 
  Robin_Watts_: generated/gen_font_cjk_full.h 16:25.39 
Robin_Watts_ No, clean generated doesn't.16:30.40 
  Is it working for you now ?16:30.46 
rayjj Robin_Watts_: there's an error in the 'clean' part of the nmake -- it needs to be: del /q ..\..\generated (was missing one level of parent and was trying to delete platform/generated16:32.43 
  Robin_Watts_: I'll patch that in the mupdf repo16:33.09 
mvrhel_laptop ugh. vs 2010 crashes again16:40.42 
Robin_Watts_ rayjj: Ah, thanks.16:40.56 
rayjj Robin_Watts_: please check my patch 16:41.22 
  Robin_Watts_: turns out it was OK except for the "Debug" configuration16:41.49 
Robin_Watts_ looks good to me.16:45.51 
rayjj Robin_Watts_: thanks.16:46.03 
  Robin_Watts_: next problem: Building mupdf/libthirdparty with VS 2005 works, but with 2013 I get a problem with mujs/jsi.h line 27: Error4error C2059: syntax error : 'sizeof'16:56.48 
  (why mvrhel_laptop doesn't see this, I don't know). Note I am just doing "master" mupdf in a directory cloned from /home/git/mupdf.git16:57.58 
Robin_Watts_ I don't see sizeof used on line 27 of mujs/jsi.h16:58.21 
rayjj (leaving gsview alone for a bit, but I saw this same error on mvrhel_laptop's gsview (win_desktop branch)16:58.45 
mvrhel_laptop weird. I have to go for a bit. wife picking me up at car shop where I have been. bbiab17:00.32 
Robin_Watts_ rayjj: I still can't see sizeof there.17:00.35 
rayjj Robin_Watts_: I know, I don't see sizeof either. Note I also get some other errors:17:00.41 
  46IntelliSense: expected an identifierc:\Artifex\mupdf\thirdparty\mujs\jsi.h2721libthirdparty17:00.42 
  47IntelliSense: identifier "x" is undefinedc:\Artifex\mupdf\thirdparty\mujs\jsi.h2772libthirdparty17:00.44 
Robin_Watts_ rayjj: pastebin all the errors please.17:00.56 
  In fact, pastebin everything :)17:01.07 
rayjj that's all three (from building libthirdparty)17:01.21 
Robin_Watts_ rayjj: That doesn't look like stuff from the "Output" window.17:02.07 
  That looks more like from the "Errors" window ?17:02.13 
rayjj Robin_Watts_: it was. From the Output Window I see: 1>c:\artifex\mupdf\thirdparty\mujs\jsi.h(27): error C2059: syntax error : 'sizeof'17:03.40 
Robin_Watts_ rayjj: Please pastebin the entire output window.17:03.58 
rayjj Robin_Watts_: http://pastebin.com/vc5WisNF17:05.24 
  Robin_Watts_: mujs is first17:05.46 
Robin_Watts_ OK, so it looks like this VS only section of the header is not working for VS2013.17:08.09 
  Which is odd.17:08.14 
rayjj I bet mvrhel built mupdf with something other than VS 2013 and so libthirdparty was already laying around :-/17:08.22 
Robin_Watts_ But maybe they updated it.17:08.27 
  so... after the #ifdef _MSC_VER do:17:08.51 
  #if _MSC_VER < 180017:09.15 
  and add a matching #endif after #define NAN17:09.27 
  rayjj: I suspect you are right. He probably built mupdf with VS2005 or thereabouts, cos that's what the solution/projects are set up for.17:10.40 
rayjj Robin_Watts_: a BUNCH more errors now (6) in jsbuiltin.h -- looks like the stem from the two uses of "static inline void ..." on lines 38 and 4417:13.30 
  Robin_Watts_: IIRC, VS uses __inline17:13.52 
Robin_Watts_ Ok, in the stuff you just #ifdeffed out...17:14.13 
  There is a #define inline __inline17:14.20 
  You need to move that to be before the #if _MSC_VER < 1800 you just added.17:14.41 
rayjj Robin_Watts_: right. I did that and it works now17:15.46 
  do you want me to patch that, or do you want to ?17:16.06 
Robin_Watts_ go for it.17:17.49 
rayjj Robin_Watts_: there were other things that need to be outside the #if _MSC_VER < 1800 (I had unresolved refs), so I moved it to just before the #define round(x) and all is OK17:20.42 
  I snprintf was missing17:21.13 
Robin_Watts_ fab.17:22.05
