| sebras | qz: it's easy to forget that one. you can always run this command: git submodule update --init it doesn't matter if the thirdparty stuff have already been cloned, then git will just checkout the correct version pointed to by mupdf. | 00:00.18 |
| qz | and after updating to latest code it looks like memleaks are gone | 00:01.07 |
| sebras | qz: great. then I take it that you managed to compile and link successfully. :) | 00:01.29 |
| qz | sebras: yeah. by the way, are there any plans on supporting saving to png with 1-2-4 bit colors (now its hardcoded to 8)? | 00:04.22 |
| sebras | qz: the only 1-bit color option that I know of is outputting to pbm. for 2 and 4 bits or 1-bit png I don't know. | 00:16.27 |
| | qz: but if something is missing we're always accepting patches. :) | 00:16.53 |
| henrys | hi mvrhel_laptop when did you get here? | 03:40.30 |
| mvrhel_laptop | hi henrys: I am in oahu right now. we go here wed. heading to maui tomorrow morning | 03:41.06 |
| | you are in maui now yes? | 03:41.59 |
| henrys | did you hook up with Robin_Watts | 03:41.59 |
| | ? | 03:42.00 |
| mvrhel_laptop | I have not heard from him yet. it has been pouring rain here most of today | 03:42.19 |
| henrys | Yes I'm in kihea | 03:42.28 |
| mvrhel_laptop | the other days had been nice | 03:42.31 |
| | we went to the surf contest yesterday | 03:43.08 |
| henrys | mvrhel_laptop: overcast here but nice, snorkeling is bad no visibility | 03:43.10 |
| mvrhel_laptop | did you read about the shark attack there the other day? | 03:43.27 |
| henrys | mvrhel_laptop: yeah I thought you and Robin_Watts were going to that which is why I asked. | 03:43.44 |
| mvrhel_laptop | I ended up going yesterday. it was going on today so he may have gone up there today | 03:44.19 |
| | I rented a car just for the one day yesterday | 03:44.27 |
| henrys | mvrhel_laptop: sharks, yikes I swam a full mile today open water and the thought did cross my mind... | 03:44.31 |
| | What beach was the attack on? | 03:47.17 |
| mvrhel_laptop | hold on I had the paper here | 03:48.15 |
| | http://mauinow.com/2013/11/29/shark-attack-forces-closure-of-south-maui-shoreline/ | 03:48.48 |
| | near you ;) | 03:48.58 |
| | probably a little east of you | 03:49.26 |
| | near the four seasons | 03:49.31 |
| henrys | mvrhel_laptop: oh my I didn't realize they were so frequent. | 03:51.40 |
| mvrhel_laptop | yes. my wife pointed this out to me yesterday. | 03:52.23 |
| | they say though that the number of people in the water is probably greater too though | 03:52.45 |
| | this is an interesting website | 03:53.21 |
| | http://oos.soest.hawaii.edu/pacioos/projects/sharks/ | 03:53.23 |
| henrys | mvrhel_laptop: well it'll make the swims a little more exciting | 03:53.26 |
| mvrhel_laptop | keeps your heart rate up | 03:53.38 |
| | henrys: are you checking into the sheraton tomorrow? | 03:53.57 |
| henrys | mvrhel_laptop: we're off to dinner - whale watchig tomorrow morning | 03:54.04 |
| mvrhel_laptop | henrys: ok have a good dinner. see you tomorrow | 03:54.25 |
| robin_watts_mac | returns from watching final of the surfing. | 04:06.24 |
| | mvrhel_laptop: ping? | 04:07.02 |
| mvrhel_laptop | robin_watts: pong | 04:07.38 |
| | robin_watts: was it raining up there? | 04:07.55 |
| robin_watts_mac | mvrhel_laptop: pissing it down. | 04:08.16 |
| mvrhel_laptop | we went up there yesterday | 04:08.17 |
| robin_watts_mac | We are both soaked. | 04:08.26 |
| mvrhel_laptop | :( | 04:08.38 |
| | we spent most of today in doors | 04:08.48 |
| robin_watts_mac | We are also pretty jetlagged so we are thinking of going to get some food fairly early. | 04:08.50 |
| | Out vague plan was to hit the Cheesecake factory before it gets too busy. | 04:09.11 |
| mvrhel_laptop | ok. we just ordered pizza and a salad | 04:09.12 |
| robin_watts_mac | ah, fair enough. | 04:09.20 |
| mvrhel_laptop | robin_watts_mac: the food court in the mall near the cheesecake factory has some nice choices too | 04:09.48 |
| | if you have a long wait | 04:09.57 |
| | maui tacos, or some good japanese ramen | 04:10.14 |
| robin_watts_mac | mvrhel_laptop: I might end up standing in line while Helen looks in shops. | 04:10.28 |
| mvrhel_laptop | ah but of course. been there | 04:10.38 |
| | robin_watts_mac: ok well sorry we were not able to hook up. I think you will have good surf for yourself here tomorrow at waikiki | 04:11.42 |
| robin_watts_mac | I hope to. | 04:13.40 |
| | Want to walk up diamondhead too. | 04:13.47 |
| | I had a quick look at the psdcmykog bug on the way over here, and it turns out to be a devn/clist bug. | 04:14.32 |
| | so I might pass that one on to you or ray :) | 04:14.50 |
| mvrhel_laptop | robin_watts_mac: we did diamond head and pearl harbor . enjoyed them both. | 04:15.05 |
| | clist bug would be good to had off to ray...... | 04:15.15 |
| | but I can take it too since he his probably busy with customers | 04:15.40 |
| | robin_watts_mac: I am trying to fix up my error catching in the windows 8 app | 04:16.59 |
| | I always seem to be bad about this sort of thing | 04:17.24 |
| | I need to get in the habit of doing it from the begining | 04:17.45 |
| robin_watts_mac | mvrhel_laptop: It's always very tempting to get stuff that works and to fix it later. | 04:18.51 |
| mvrhel_laptop | yes | 04:19.09 |
| robin_watts_mac | We visited Pearl Harbour last time. Arizona memorial was interesting, as was the Mighty Mo. | 04:30.21 |
| | There is also a WWII submarine there, the Bowfin, which we enjoyed. | 04:30.49 |
| | Once again, I will repeat my recommendation for the Atlantis submarine trip on Maui. | 04:31.27 |
| | Get the kids to wear something red if you do it. | 04:31.49 |
| mvrhel_laptop | robin_watts_mac: yes, we did the memorial, Mighty Mo and Bowfin | 04:49.19 |
| | that was all fun | 04:49.23 |
| leni536 | hi | 09:28.32 |
| kens | Hmm, ghostbot is sulking | 09:29.02 |
| leni536 | robin_watts: I read your answer in the logs about LCD subpixel rendering | 09:29.24 |
| | I think it would be a nice feature (at least as an option for different subpixel orders) | 09:30.11 |
| | I think there are only two pdf viewers on linux which does this | 09:30.37 |
| kens | Its pretty late where Robin is at the moment. I don't think it likely that the MuPDF developers will consider a 'ClearType' type of rendering though | 09:30.48 |
| leni536 | acroread and pdf.js | 09:30.59 |
| | Why? | 09:31.49 |
| | Is it because pf patent problems? | 09:32.04 |
| kens | Its device-specific for one (different arrangements of pixels require diefferent munging) and most of us consider it to be terribly ugly | 09:32.21 |
| | ClearType is patented, not sure if it affects other rendering | 09:32.54 |
| leni536 | What do you think of this kind of rendering: http://www.oyhus.no/SubLCD.html ? | 09:35.58 |
| kens | I think I'd want to see it working on my screens, not in a screenshot | 09:36.29 |
| mvrhel_laptop | :) | 09:36.43 |
| kens | And it does still have colour fringing | 09:37.03 |
| leni536 | Ok, I think it's a tradeoff between colour fringing and resoulution and it's just a matter of taste | 09:39.01 |
| kens | Personally I detest colour fringing and find it terribly obvious, I don't find the pseudo-higher resolution any benefit. Especially given the rapidly increasing resolutionof modern displays. | 09:39.56 |
| mvrhel_laptop | right | 09:40.18 |
| | night all | 09:40.20 |
| kens | But mine is not the final (or even the first) word on the subject | 09:40.23 |
| | Night micahel | 09:40.27 |
| leni536 | Ok, it would be nice as an option anyway, especially that mupdf is a backend for many pdf readers. | 09:42.55 |
| | Thanks and good bye | 09:43.25 |
| kens | You'll have to see what the MuPDF developers say, its not up to me. | 09:43.26 |
| leni536 | Ok, thanks | 09:43.58 |
| tor7 | kens: I'm with you, I detest the colour fringing. if anyone wants it terribly, we say to render at 3x the width and do the filtering in the app. | 09:55.20 |
| kens | tor7 :-) | 09:55.30 |
| tor7 | kens: Dell "leaked" some info on a new 24" monitor, 3840x2160 resolution | 09:56.27 |
| | http://www.anandtech.com/show/7556/dell-leaks-details-of-a-24-uhd-4k-3840x2160-monitor-the-up2414q | 09:56.55 |
| kens | I had a feeling that MuPDF already did sub-pixel rendering, but wasn't certain enough of my ground to say that, so I was pleased to see Robin's response. I didn't really expect that he wanted the LCD sub-pixel stuff.... | 09:56.57 |
| | Hmmm I wonder how much they are going to charge for that beast...... | 09:57.22 |
| tor7 | we do subpixel accurate metrics and aa font rendering taking the offset into account | 09:57.24 |
| | but we don't do any subpixel color decimation filtering | 09:57.34 |
| kens | Yes, that's what I meant. Proper sub-pixel rendering;-) | 09:57.51 |
| tor7 | indeed :) | 09:57.55 |
| | calling the color fringing abomination sub-pixel rendering is just confusing | 09:58.15 |
| kens | Yeah, which is why I asked him what it was he actually wanted :-) | 09:58.30 |
| tor7 | kens: the current crop of high-dpi IGZO panels cost more than a small car :( | 09:58.38 |
| kens | O.O | 09:58.45 |
| | Oh well, I guess in a few years.... | 09:59.04 |
| tor7 | the Eizo 30" 4k (yet another horrible term) costs 20k GBP or thereabouts | 09:59.15 |
| kens | Yikes! | 09:59.27 |
| | That's wiorse than the old colour-calibrated CRT days | 09:59.40 |
| tor7 | there are some slightly smaller almost-4k that are in the 2k GBP range | 09:59.50 |
| kens | Still too rich for me | 10:00.03 |
| tor7 | so I'm hoping the dell will be reasonable priced (sub 1k GBP and I'm happy) | 10:00.18 |
| | all my other monitors after using the chromebook pixel look horribly blurry :( | 10:00.44 |
| kens | Well if its Dell it likely to be reasonable, but whether its that low...... | 10:00.51 |
| tor7 | kens: my biggest gripe with it will be the 16:9 aspect ratio... | 10:01.19 |
| | but I think the high-dpi trumps most other concerns :) | 10:01.27 |
| kens | I think htere's no getting away from teh aspect ratio these days | 10:01.42 |
| fang | I am using convert which calls ghostscript to convert pdf files to jpg, the pdf files contain scanned content, when in command line it works fine, but when I call it from php script using exec it fails | 14:13.07 |
| | Error: /undefined in findresource Operand stack: --dict:7/16(L)-- F4 4.5 --dict:5/5(L)-- --dict:5/5(L)-- SimHei -$ Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval$ Dictionary stack: --dict:1155/1684(ro)(G)-- --dict:1/20(G)-- --dict:75/200(L)-- --dict:7$ Current allocation mode is local Last OS error: 2 | 14:13.42 |
| kens | THen there is some difference in the way you are calling convert or Ghostscript | 14:13.51 |
| fang | may be the fonts path | 14:14.11 |
| | but I don't know how to solve it | 14:14.22 |
| kens | THat is saying that the CIDFont SimHei is not available. Since you are getting an error, instead of a substitution for DroidSansFallback you must be running an old version of Ghostscript | 14:14.34 |
| fang | it works fine in command line | 14:15.07 |
| kens | fang, you need to look at the environment of the users to start with and look for any environment variable which begins GS_ | 14:15.08 |
| | Since tghe command line works, its not a Ghostscript bug, it must be the wnvironment your script is using. THat's about all I can tell you. | 14:15.52 |
| fang | how can I look for the env variables, any command? | 14:16.28 |
| kens | I am not a Lnux expert | 14:16.41 |
| fang | ok, thanks, I'll google | 14:17.00 |
| marco | Hello to everyone | 15:59.46 |
| Guest13093 | I need some help.. Can somebody help me a little on mupdf for android? | 16:01.17 |
| chrisl | Guest13093: probably not right now - the relevant engineer(s) aren't around just now. If you leave your question, this channel is logged, hopefully they'll see it and reply at some point | 16:03.32 |
| Guest13093 | Thank you. Basically i need to preset some fields before. Doing so i've implemented a new native method: | 16:06.04 |
| | JNIEXPORT jboolean JNICALL JNI_FN(MuPDFCore_setFieldValueInternal)(JNIEnv * env, jobject thiz, jstring jname, jstring jvalue) { LOGI("MuPDFCore_setFieldValueInternal"); jboolean result = JNI_TRUE; const char *name; const char *value; globals *glo = get_globals(env, thiz); fz_context *ctx = glo->ctx; page_cache *pc = &glo->pages[glo->current]; name = (*env)->GetStringUTFChars(env, jname, NULL); if (name == NULL) { | 16:06.06 |
| | in the onCreate of activity i call this native method: core.setFieldValueInternal(key, value); | 16:07.11 |
| | The problem is that the field value is correctly setted internally (when i tap on the form, the appearing edit text has the presetted value) but the value has not been drawn in the pdf view of my activity | 16:09.57 |
| | i don't find details regarding this procedure. Maybe i miss something | 16:11.04 |
| | Thanks for the help :) | 16:11.21 |
| | the definition of the previous funtion has been cutted. Here is complete: | 16:16.01 |
| | JNIEXPORT jboolean JNICALL | 16:16.11 |
| | JNI_FN(MuPDFCore_setFieldValueInternal)(JNIEnv * env, jobject thiz,jstring jname, jstring jvalue) { | 16:16.26 |

| kens | OK I@m off, goodnight all | 17:04.31 |
| speed804 | Anyone have a sec to help me with a newb question? | 17:19.44 |
| | I just downloaded and installed ghostscipt. Then I tried to run a command I found online and two things happened. It didn't find any fonts, and nothing happened outputwise :( | 17:20.56 |
| | Is there something else I need to do to initialize ghostscript before using it? | 17:21.23 |
| chrisl_t530 | speed804: downloaded ghostscript from where and installed it on what? | 17:27.33 |
| speed804 | I will get that for you in a sec, just trying to find the main download page again | 17:29.42 |
| chrisl_t530 | Was it from ghostscript.com? | 17:30.06 |
| speed804 | http://www.ghostscript.com/download/gsdnld.html | 17:30.43 |
| chrisl_t530 | And on what platform? | 17:30.59 |
| speed804 | sorry this one http://downloads.ghostscript.com/public/gs910w64.exe | 17:31.17 |
| | win 7 64 bit | 17:31.21 |
| | I installed it in a sub folder of my desktop | 17:31.47 |
| | I am trying to merge pdfs and then add bookmarks to them | 17:32.34 |
| chrisl_t530 | pdfwrite isn't really intended for merging/modifying PDFs | 17:33.16 |
| speed804 | I started from this http://stackoverflow.com/questions/2969479/merge-pdfs-with-pdftk-with-bookmarks/20333267#20333267 | 17:33.34 |
| | ghostscript seems to be able to merge pdf files keeping the bookmarks intact and it seems to be able to execute postscript statements with pdfmarks | 17:34.25 |
| | this would allow me a lot more freedom then my current method | 17:34.35 |
| | I think. | 17:34.39 |
| | By isn't intended, do you mean it won't work well? | 17:35.03 |
| chrisl_t530 | speed804: it will almost always work fine, there are occasional issues with subset fonts, though | 17:35.35 |
| speed804 | Our files I am working with have all the same fonts in them, so if there are some that aren't already distributed in the executable I could maybe find them? | 17:36.32 |
| chrisl_t530 | Hrm, I'm not sure about Windows - you might have to use the -sFONTPATH option - something like -sFONTPATH=c:/Windows/Fonts | 17:36.55 |
| speed804 | Right now it seems to only be having issues with standard fonts | 17:38.21 |
| | http://www.heypasteit.com/clip/12M0 | 17:38.22 |
| chrisl_t530 | ArialMT is not a standard font | 17:38.55 |
| speed804 | OK. I guess I just saw Arial and thought it should be good lol. | 17:39.30 |
| chrisl_t530 | Remember from our POV "standard" means required by the PDF (Postscript) spec | 17:40.12 |
| speed804 | But either way, it said it substituted something for it, so it still should have given me an output file right? | 17:40.26 |
| chrisl_t530 | Yes | 17:40.35 |
| speed804 | I tried without the postscript and still got nothing | 17:41.52 |
| chrisl_t530 | I would suggest trying a simpler command line, and having the output file written to the current directory | 17:42.03 |
| speed804 | This is what I just tried sendinput gswin64c.exe -o %merged% -f %input1% %input2% | 17:42.27 |
| | all three of the file variables have the full directory | 17:42.54 |
| chrisl_t530 | Do away with the variables, and try with explicit file names | 17:43.14 |
| speed804 | The current directory is the directory of gswin64c.exe right? | 17:43.16 |
| chrisl_t530 | The current directory is the one you are in | 17:43.34 |
| speed804 | based on the one in the command line? You have to set the directory of the .exe before running any gs commands right? | 17:44.39 |
| | I do cd /d binpath ^ where binpath is the directory of the .exe | 17:45.28 |
| chrisl_t530 | Right, so do something like: gswin64c.exe -o outputfile.pdf inputfile.pdf | 17:46.20 |
| speed804 | gswin64c.exe -o merged.pdf -f DLC-1-1.pdf DLC-1-2.pdf | 17:46.43 |
| | I just tried that and still no luck | 17:46.50 |
| chrisl_t530 | No, one input file | 17:46.56 |
| speed804 | k | 17:47.05 |
| | still no luck | 17:49.11 |
| | Do I need to install a ghostscript pdf printer or something before this will work? | 17:49.33 |
| chrisl_t530 | No | 17:49.43 |
| speed804 | Do I need to use the gswin64c.exe if I am running it from the commandline? | 17:51.11 |
| | I assumed that but didn't check yet. | 17:51.20 |
| chrisl_t530 | It is possible there's a problem related to doing stuff under the Desktop, I've never tried that | 17:52.13 |
| | What else would you expect to use? | 17:52.51 |
| | oh, I didn't notice: you're specificying the device, are you? | 17:55.13 |
| speed804 | Instead of gswin64c.exe there is gswin64.exe | 17:55.49 |
| chrisl_t530 | You need to add in -sDEVICE=pdfwrite to your command line | 17:55.50 |
| speed804 | I thought the -o assumed the -sDEVICE by the .extension of the input file | 17:56.16 |
| | But I will give it a shot | 17:56.46 |
| chrisl_t530 | No, Ghostscript doesn't make (m)any such assumptions. | 17:56.55 |
| speed804 | That did it :) | 17:57.53 |
| chrisl_t530 | Cool, obvious once I realised.... as usual! | 17:58.14 |
| speed804 | That font ArialMT isn't even in my windows fonts folder | 17:58.45 |
| | Thank you so much for your help by the way! | 17:59.04 |
| chrisl_t530 | No worries | 17:59.14 |
| speed804 | Do you know if a font can be in a microsoft word folder and not the windows folder? | 17:59.29 |
| chrisl_t530 | I don't sorry, I'm not really a Windows guy | 17:59.52 |
| | speed804: you can setup mappings for fonts, but it's not the most straight forward thing in the world | 18:01.13 |
| speed804 | By mapping, do you mean substitutions? Or are substitutions just an example of modifying the mapping | 18:05.29 |
| | ? | 18:05.30 |
| | I read the substitutions bit and it seemed relatively straight forwards | 18:05.47 |
| chrisl_t530 | Yes, you can define substitutions using name/file mappings. The problem, on Windows, is that the initialisation files are built into the executable, and complicates things a little | 18:06.40 |
| speed804 | Does gs ever misread what a font is called? | 18:06.50 |
| | Hey actually, when I put the sDEVICE in it didn't give me any font errors | 18:07.28 |
| | Maybe I am fine | 18:07.41 |
| | If it can use system fonts then there shouldn't be any fonts I am coming across that aren't in the system folder | 18:08.02 |
| chrisl_t530 | That probably means you're not getting fonts embedded in the output PDF | 18:08.19 |
| speed804 | Does that mean it should look different or just a pdf coding issue? | 18:09.05 |
| | Because the original and the merged one look the same | 18:09.19 |
| chrisl_t530 | They will - on your computer. Not embedding fonts means PDFs can look different on different computers. They end up using whatever fonts are available on the viewing computer | 18:10.08 |
| speed804 | How do you know it is doing that? | 18:10.28 |
| | That may or may not be an issue | 18:10.40 |
| chrisl_t530 | Open the PDF in Acrobat you can check whether fonts are embedded or not | 18:11.17 |
| | speed804: given that your original PDFs didn't have fonts embedded, it's probably considered acceptable in your circumtance | 18:12.49 |
| ray_laptop | marcosw: seems like we both thought that the other wasn't working today. Guess it would have been better had my IRC been up :-/ | 19:31.03 |
| | At least Phil can't say he didn't get a prompt reply :-) | 19:31.23 |
| | marcosw: BTW, I couldn't log into 'miles' -- I know I used to be able to. Has something changed ? | 19:34.37 |
| marcosw | ray_laptop: I haven't (intentionally) changed anything on miles; I'll try to see if there is an obvious reason you can't log in. | 20:51.07 |
| speed804 | Hello, I have learned how to use ghostscript and postscript to add bookmarks to pdfs, does anyone know a way I could remove bookmarks? | 20:52.30 |
| | Or edit existing ones? | 20:52.46 |
| marcosw | ray_laptop: the access settings on ~ray/.ssh were too permissive, so I've fixed them, but I would have expected that to give you an error message on your side. Are you using the correct ip address: 50.240.204.222 ? | 21:00.33 |
