| Robin_Watts | paulgardiner, chrisl: The other thing we need to bring to the snowmobiling are waterproof gloves. | 10:56.56 |
| | I just bought these:http://www.amazon.co.uk/gp/product/B00NW8W6WC?psc=1&redirect=true&ref_=od_aui_detailpages00 | 10:57.10 |
| | I bought large, and they are the right size for me. | 10:57.30 |
| | My hands are 20cm/8in around the palm, if that helps. | 10:58.08 |
| chrisl | I've got these: http://www.amazon.co.uk/Black-Canyon-Thinsulate-Gloves-Reinforced/dp/B0030C44TI/ref=sr_1_4?s=sports&ie=UTF8&qid=1425293987&sr=1-4&keywords=thinsulate+ski+gloves | 11:00.35 |
| | Should be okay..... | 11:00.46 |
| Robin_Watts | yeah, lovely. | 11:01.10 |
| | It dawned on me over the weekend that though I have lots of good gloves, none were waterproof. | 11:01.27 |
| chrisl | I only had gardening or mechanics gloves, and one other pair I can't find, hence buying those. | 11:02.39 |
| paulgardiner | Robin_Watts: your link gives me X-Large only | 11:02.58 |
| Robin_Watts | ooh, maybe I got the last large pair. | 11:03.19 |
| | I got the PDF name reworking working last night. | 11:13.54 |
| | It used to take 35 Meg to load the PDF outline on the file from 695761. | 11:14.27 |
| | It now takes 30. | 11:14.32 |
| | sorry, that should be 39.1 -> 35. | 11:15.11 |
| | The code is still using strcmp though, so the potential speedups can't be measured yet. | 11:15.50 |
| Manoj_ | Hi | 11:20.57 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 11:20.57 |
| Manoj_ | Hi I am getting this error while compiling lib : /obj/local/armeabi-v7a/objs/mupdf/mupdf.o: in function drop_page_cache:jni/mupdf.c:140: error: undefined reference to 'fz_free_page' | 11:21.51 |
| | anybody? How can I get rid of this error | 11:22.58 |
| | ? | 11:23.01 |
| Robin_Watts | Manoj_: You're missing a fix from git. | 11:28.07 |
| | Pull in the latest version and you should be fine. | 11:28.23 |
| | fz_free_page is now called fz_drop_page. | 11:28.32 |
| | Hmm. Addinic Debugger GUI is out for Ubuntu... | 11:40.54 |
| | Affinic, sorry. | 11:41.00 |
| chrisl | It looks like it give access to the debugger command line - could be interesting.... | 11:42.03 |
| Robin_Watts | It does. | 11:48.25 |
| | I have it installed here on MacOSX. | 11:48.40 |
| | It's not perfect, but it's better than others I've tried. | 11:48.53 |
| chrisl | It really looks like a modernized ddd - unfortunately, UbuntuOne seems to be having a problem with my username/password. I'll try it out at some point | 11:49.44 |
| AjayK | Hello. I am using GS to convert PDF to Image. I am using the following switches: -dSAFER -dNumRenderingThreads=2 -dUseCropBox -dNOPAUSE -sDEVICE=tiffg4 -r300 -dBATCH. This creates a bitonal image which is what I want. But the quality is not good when compared to using Informatik with resolution 300 and TIFF CCITT4 BLACK in TIFF compression. Any help? | 11:55.32 |
| chrisl | AjayK: you probably need to tailor the halftone to your needs | 11:56.58 |
| Robin_Watts | AjayK: An alternative would be to try the downscaler. | 11:57.19 |
| AjayK | chrisl: hmm. What is the switch to alter halftone? | 11:58.22 |
| chrisl | AjayK: one is: -dDITHERPPI= | 11:58.52 |
| AjayK | Robin_Watts: But downscaller is used with tiffsep and tiff scaled. and using that increases the output size significantly | 12:00.04 |
| Robin_Watts | gs -sDEVICE=tiffscaled -r900 -dDownScaleFactor=3 -o out.tif gs/examples/tiger.eps | 12:00.07 |
| | AjayK: A 1bpp bitmap of a given resolution will be (uncompressed) the same size regardless of what device it comes from. | 12:01.00 |
| | If you are seeing different sizes for bitmaps of the same size, using the same compression method, then it's a sign that the larger one has less compressable data in it. | 12:01.38 |
| | s/sizes/file sizes/ | 12:01.52 |
| chrisl | I'd guess tiffscaled doesn't compress (at least by default) | 12:02.12 |
| Robin_Watts | less compressable data == more random. | 12:02.19 |
| | more random probably means higher quality. | 12:02.32 |
| chrisl | So add -sCompression=g4 to the tiffscaled command line | 12:03.02 |
| Robin_Watts | -sDEVICE=tiffscaled -r900 -dDownScaleFactor=3 -sCompression=g4 -o out.tif works for me. | 12:03.24 |
| | That will give you effective AA as well. | 12:03.47 |
| chrisl | Hmm, anti-aliasing with halftone..... :-( | 12:04.15 |
| | AjayK: and for info in -dDITHERPPI see: http://www.ghostscript.com/doc/current/Use.htm#Rendering_parameters | 12:04.19 |
| Robin_Watts | But : -sDEVICE=tiffscaled -r300 -dDownScaleFactor=1 -sCompression=g4 will probably be better than you were getting anyway. | 12:04.39 |
| | chrisl: Annoyingly it's not available on the app store for 14.10. | 12:06.10 |
| | This seems to be a download link:http://www.insofter.com/download/5009881/1425308209/b14797197e881b7c5a9055e5053a4dae | 12:06.19 |
| chrisl | Robin_Watts: this machine is only 14.04. I did try it once before, I forget why I didn't keep using it...... | 12:07.54 |
| Robin_Watts | For some reason my mac won't ping ghostscript.com | 12:16.03 |
| | won't resolve it. | 12:16.10 |
| chrisl | It's fine here on linux..... | 12:16.33 |
| Robin_Watts | fine on windows and linux... | 12:17.26 |
| chrisl | Robin_Watts: what does nslookup say? | 12:19.45 |
| Robin_Watts | I think it's my mac at fault. Possibly to do with parallels. | 12:20.23 |
| | Yeah, the windows XP VM on the mac can ping it, but the mac can't. | 12:20.59 |
| AjayK | Still its not the required output. This is the output from Informatik: "http://s9.postimg.org/kr5h4ljnj/0003.png". This is the output from GS with the new switches: "http://s27.postimg.org/5i7gomsgj/0003.png" | 12:49.29 |
| | specifically look at the diagram. With GS, it contains white spots. Even though it looks more smoother to me. But I want a similar output as I am getting with Informatik | 12:51.30 |
| Robin_Watts | That looks like the blacks aren't really black. | 12:52.49 |
| | If the input PDF (or postscript) file renders the text as dark gray, then we'll attempt to honour that. | 12:53.55 |
| AjayK | yes i agree. in the pdf as well, its not pure black. | 12:54.01 |
| Robin_Watts | So, we are rendering it correctly. | 12:54.12 |
| | We might not be rendering it as you'd like it to be rendered, but... :( | 12:54.30 |
| | Now, possibly you can fudge something with ICC profiles? | 12:54.48 |
| AjayK | i think ghostscript output is better but is it possible to achieve the other result? | 12:55.06 |
| | no idea about that :/ | 12:55.15 |
| Robin_Watts | AjayK: Possibly there is an ICC profile in the pdf file that's upsetting it, and telling gs to ignore that profile would work? | 12:55.55 |
| chrisl | Do you know what halftone technology Informatik is using? | 12:56.42 |
| AjayK | No Idea. Informatik gives 2 options: 1. graphics formatt = "TIFF" 2. Tiff Compression = "TIFF CCITT4 BLACK" | 13:21.42 |
| | Robin_Watts: Sorry I didn't get you | 13:22.30 |
| chrisl | AjayK: try using -dOverrideICC see if that makes any difference | 13:24.48 |
| | AjayK: you could also try using -dUseFastColor=true | 13:25.32 |
| AjayK | the quality does improve but there are still white spots on both the diagram as well as text | 13:27.46 |
| chrisl | Well, if the "black" isn't black then you get the halftone pattern, that's the way it works | 13:29.12 |
| | AjayK: Possibly drop both the -dOverrideICC and -dUseFastColor=true and try -dKPreserve=1 or -dKPreserve=2 | 13:33.48 |
| AjayK | no success. I used the following command: gswin32c -dSAFER -dNumRenderingThreads=2 -dUseCropBox -dNOPAUSE -sDEVICE=tiffscaled -r900 -dDownScaleFactor=3 -dKPreserve=1 -sCompression=g4 -sOutputFile=output\%04d.tif D21901.PDF | 13:35.08 |
| chrisl | AjayK: try switching back to tiffg4 | 13:36.25 |
| AjayK | more 1 spots are appearing if i zoom in to maximum. | 13:38.30 |
| chrisl | Well, don't zoom | 13:38.52 |
| Manoj_ | hello | 14:52.29 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 14:52.29 |
| Manoj_ | all | 14:52.30 |
| | I have one more issue | 14:52.37 |
| | I am passing r,g,b values to mupdf.c I am passing yellow color with 255.0 238.0 0.0 but its rendenring green :-( | 14:53.27 |
| | Any one on mupdf? | 14:54.23 |
| henrys | Manoj_:might want to try back later. | 15:24.41 |
| | | 15:24.42 |
| | | 15:24.42 |
| | mvrhel_laptop: do you leave tomorrow? | 15:24.57 |
| chrisl | henrys: I think mvrhel_laptop is travelling today | 15:52.27 |
| henrys | chrisl: ah okay, I saw he joined the chat room and thought he might be around. | 15:55.11 |
| chrisl | henrys: I'm just going by what I remember from talking to kens on Friday, so not gospel...... | 15:56.13 |
| henrys | chrisl: when do you leave? | 16:02.24 |
| chrisl | henrys: Thursday | 16:02.51 |
| Robin_Watts | Damn. I missed Manoj. Was running dog to vets. | 16:08.04 |
| chrisl | Well, we're not all here all the time, if they can't be patient...... | 16:09.34 |
| henrys | bbiab | 16:15.45 |
| | Robin_Watts: how's the boiler? | 16:55.09 |
| Robin_Watts | boiler was fixed saturday. End of World postponed. | 16:55.26 |
| marcosw | Robin_Watts: Have you received an amazon package for me? | 16:58.32 |
| Robin_Watts | marcosw: I have. Looks like a hardback book? | 16:58.45 |
| marcosw | eggscellent | 16:58.53 |
| henrys | marcosw: miles is referring but the Vietnamese font customer to URW but we should have fielded it earlier. They complained we were not responsive. | 16:58.54 |
| | s/but// | 16:59.08 |
| | anybody looking at the new micro desktops, it'd be real nice to replace henrysx6 with on of these: http://www.dell.com/us/business/p/optiplex-9020m-desktop/pd | 17:01.06 |
| chrisl | henrys: that mail (Vietnamese font) was addressed to sales, only cc'ed to support - I'd expect Scott to deal with it | 17:01.53 |
| Robin_Watts | Sure, if you don't want graphics. | 17:02.01 |
| | or an optical drive, or more than one HD... | 17:02.32 |
| marcosw | henrys: oops, I saw that email but since it was addressed to sales@ I didn't reply. I figured Scott had replied but not cc'd support. | 17:02.55 |
| henrys | marcosw: that was my initial response to Miles but I think if we know Scott would not understand the request we should jump in. | 17:03.43 |
| | marcosw: that said I think it's on Scott and Miles to get those. | 17:04.57 |
| | marcosw: thinking more about it I'm going to push Scott to field it if it is To:sales... as a matter of protocol. It's too confusing to have multiple responders. | 17:08.00 |
| Robin_Watts | brb | 17:17.26 |
| henrys | chrisl: do you know of any open source Vietnames fonts that would work? | 17:23.43 |
| Robin_Watts | henrys: Supposedly noto sans supports vietnamese. | 17:25.28 |
| chrisl | Yeh, noto would be my first suggestion | 17:25.51 |
| Robin_Watts | But we'd have to hunt for which one of the many files has them in. | 17:26.01 |
| marcosw | chrisl: are you going to bring your new pc to the meeting so we can be amazed by it's noiselessness? | 17:29.21 |
| chrisl | marcosw: although I was surprised by the relatively small case, it's still a little large for travelling! | 17:30.06 |
| | henrys: Vietnamese fonts seem to be rather thin on the ground in open source guise..... | 17:33.37 |
| | marcosw: besides, I'll shortly be spoiling the silence slightly by installing a spinning platter drive into it | 17:34.22 |
| hyper_ch | howdy | 18:16.46 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 18:16.46 |
| hyper_ch | is there a way to strip an ocred pdf from the text layer? | 18:19.34 |
| mvrhel_laptop | henrys: I am heading out is a bit | 18:21.22 |
| | had to run to dr. appt this morning | 18:21.33 |
| | looks like the temps are going to be very low tomorrow and wed | 18:21.53 |
| henrys | mvrhel_laptop: yeah I was sorry to see that. Usually warmer this time of year. | 18:22.30 |
| | mvrhel_laptop: I was going to warn you guys to make sure about snow tires. The roads should be okay but best to be safe. | 18:23.23 |
| mvrhel_laptop | henrys: I hope the cargo van has decent tires | 18:30.47 |
| | I was wondering about that last night | 18:30.53 |
| henrys | mvrhel_laptop: you can call and make sure... and pick something else if it doesn't. | 18:31.14 |
| mvrhel_laptop | right. I just threw my sorels in the suitcase too. It dawned on me that running around in sneakers may not be ideal | 18:31.45 |
| | heading out. see you all soon | 18:55.27 |
| kens | evening all :-) | 23:44.14 |
| | Hmm so Michaels on his way, I wonder when he gets in..... | 23:48.51 |
