| simon91 | Robin_Watts: Good morning. | 08:30.25 |
| | The strtof patch I uploaded yesterday breaks the build of scripts/cmapdump.c | 08:31.16 |
| | Thats because cmapdump.c uses several includes with fitz and pdf source files. | 08:32.19 |
| | Fixed it by adding the required object files to the cmapdump link command line in the Makefile. | 08:33.18 |
| | Thats now 'Patch (Version 2)' in report. | 08:34.18 |
| | tested to compile under linux | 08:35.41 |
| kens | simon91 : its a little early for Robin yet | 08:53.21 |
| simon91 | kens: is he not online? | 08:54.41 |
| kens | His *computer* might be :-) | 08:55.02 |
| Robin_Watts | Morning simon91 | 10:00.06 |

| leonardo_ | hi! how can i convert a srgb pdf to cmyk pdf with pure black text using ghostscript? | 15:55.13 |
| | i am trying to do it for a couple days now. sorry for bad english | 15:55.52 |
| kens | Set -sColorConversionStrategy=/CMYK and hope that your test is actually black to start with | 15:55.56 |
| | s/test/text/ | 15:56.06 |
| leonardo_ | i am creating pdf using wkhtmltopdf | 15:56.56 |
| kens | shrugs | 15:57.13 |
| leonardo_ | I made a test using acrobat pro | 15:58.35 |
| | if I use the option preserve black | 15:58.46 |
| | it works good | 15:58.50 |
| | but I cannot make preserve black work on ghostscript | 15:59.07 |
| kens | Ghostscript is not Acrobat | 15:59.22 |
| | Have you tried what I suggested ? | 15:59.33 |
| leonardo_ | -sColorConversionStrategy=CMYK returns rich black | 16:00.28 |
| | I tried to create a profile using photoshop. but I 'm not sure i did it correctly | 16:01.06 |
| | what kind of profiles should i use on ghostscript? | 16:02.17 |
| | can some one help me? | 16:06.23 |
| | I tried to use this gs -dNOPAUSE -o /home/user/teste945.pdf -sDEVICE=pdfwrite -sColorConversionStrategy=CMYK -sOutputICCProfile=/home/smarket-server/cmyk.icc -dOverrideICC=true -dKPreserve=1 -dDeviceGrayToK=false /home/user/zWUCUZJB_10049.pdf | 16:08.25 |
| | but still doesn't work | 16:08.36 |
| HenryStiles | leonardo_: looks like ken lost his connection and he's the guy to help with this. | 16:12.08 |
| leonardo_ | ok I try it later! thanks! | 16:13.08 |
| | nobody else can help me with ghostscript? | 18:11.27 |
| Robin_Watts | leonardo_: With pdfwrite questions, ken is the guy to ask. | 18:18.01 |
| | He's here every day between 9 and 5 UK time. | 18:18.13 |
| HenryStiles | leonardo_: you've done stackoverflow? I didn't look hard but this'd be where I'd start with google "site:stackoverflow.com ghostscript CMYK black" | 18:20.26 |
| | you can also post your question there. | 18:20.47 |
| leonardo_ | I have tried everything in stack overflow, google groups, ghostscript doc, etc. Nothing works. | 18:39.25 |
| | And I only have to do a small modification in the file | 18:40.51 |
| | I will try to contact him tomorrow | 18:41.29 |
| | thank you | 18:41.32 |
| Robin_Watts | tor8: ping | 19:40.19 |
| | Oh, not here. Pants. | 19:40.43 |
| | tor8: For the logs, then. | 19:41.19 |
| | I've hit a problem with the font fallback thing we discussed. Suppose I have the text ABC that we're trying to render in Times-Roman. | 19:42.04 |
| | A is an arabic char, and B is a diacritic that gets shaped onto A. | 19:42.31 |
| | We encode A with fallback, and get told that it's not in Times-Roman, so use the Noto Arabic fallback. | 19:43.01 |
| | We encode B with fallback, and get told to use Times-Roman. | 19:43.39 |
| | This is because ucdn tells us that B is of 'unknown' script. | 19:44.05 |
| | Oh, I can solve this by using the node->script that I cunningly saved from the output of the bidi stuff. | 19:46.06 |
| jstein | Hi, I tried to compile ghostscript-gpl-9.18 on gentoo Linux, but it fails and I have no clue how to help the package to compile https://bpaste.net/show/005389e4791e Besides that, the linked log file shows a several warnings about unused variables... I am not sure, if the developers are interested in bugreports about this, because their compiler could show it to them too... | 19:53.51 |
| Robin_Watts | jstein: We've fixed a lot of such warnings since 9.18. | 20:01.51 |
| | As to why it won't build for you... where did you get the sources? | 20:02.04 |
| jstein | its from the gentoo package. https://gitweb.gentoo.org/repo/gentoo.git/tree/app-text/ghostscript-gpl/ghostscript-gpl-9.18.ebuild?id=496566c75f483786d581f34196309bc4becb2481 | 20:11.18 |
| | It fetches: http://downloads.ghostscript.com/public/${MY_P}.tar.bz2 while MY_P is a package name with version number | 20:11.55 |
| chrisl | jstein: you'll have to contact the gentoo package maintainers. It may well be something that can be/needs addressed in our stuff, but I cannot help with the gentoo build/packaging system, the patches and changes it makes | 20:12.54 |
| Robin_Watts | jstein: From your build log, it can't find zlib.h | 20:14.27 |
| | the sources *as we supply them* have zlib inside them. | 20:14.41 |
| | Package maintainers like to break everything by using system packages. | 20:14.56 |
| | Having said that, I'd stake chrisl's life on your not wanting to build the gprf device anyway :) | 20:15.52 |
| jstein | Robin_Watts: that was very helpful. Thank you. It may be, that the maintainer has to fix the path for zlib | 20:16.01 |
| | what is gprf? | 20:16.57 |
| Robin_Watts | It's a device we use for a particular proofing solution. | 20:17.16 |
| | no one will want to use it in normal use. | 20:17.37 |
| chrisl | Oh, there was a problem with gprf and xpswrite not working with the system zlib. Fixed a bit over a week ago | 20:17.44 |
| Robin_Watts | chrisl: Ah, that'll be it then. | 20:17.58 |
| | jstein: There will be a new release within 2 months or so, or you can grab the current code. | 20:18.33 |
| jstein | * Skipping ghostscript-gpl-9.12-sys-zlib.patch due to EPATCH_EXCLUDE ... | 20:19.01 |
| | ^^ found this line in the logs | 20:19.11 |
| | may be we need this patch for 9.18 and its fixed then | 20:19.28 |
| chrisl | No idea - that's nothing to do with us...... | 20:19.47 |
| jstein | chrisl: is there a release with the fix already, or is it only in the nightly snapshot? | 20:21.09 |
| smsklar | Hello, I just tried to open an EPS file using gsview and it said, Ghostscript failed to distill PS. Can you explain why this may have happened? The file was an EPS | 20:21.12 |
| chrisl | jstein: it will be fixed in the *next* release - we don't do "nightly snapshots" | 20:21.49 |
| Robin_Watts | jstein: You can grab a snapshot of the latest code from http://git.ghostscript.com/?p=ghostpdl.git;a=shortlog though | 20:23.40 |
| | smsklar: gsview 6 ? | 20:24.04 |
| chrisl | jstein: Or, if you can find out how to add another patch to the partage recipe, you can pull in the fix: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=da79b51a8bc3aeb4c4e55ae4ce6ebe07b34b93cf | 20:24.11 |
| Robin_Watts | gsview 6 is secretly just a PDF viewer. So if you give it an EPS to look at, it will call gs to "distill" the EPS to PDF and then view that. | 20:25.22 |
| | So something went wrong in that process. | 20:25.39 |
| jstein | chrisl Robin_Watts: I have collected all information for the gentoo guys in hope that they can fix it now. https://bugs.gentoo.org/show_bug.cgi?id=573248 Thank you for your help. | 20:34.14 |
| Robin_Watts | jstein: No worries. They are welcome to come here and ask questions too (but distro maintainers almost never do) | 20:34.48 |
| jstein | Robin_Watts: I have made a statistic recently, that shows 10 gentoo devs are responsible for 90% of the Packages and they mostly do it in they spare time. This explains the sad situation a bit... | 20:37.37 |
| tkamppeter | mvrhel_laptop, hi | 22:52.51 |
| mvrhel_laptop | hi tkamppeter | 22:53.01 |
