| kens | ping marcosw | 00:27.34 |
| chrisl | kens: the other film I watched was Total Recall - I finally remembered! | 00:32.00 |
| kens | ROFL | 00:36.32 |
| robin_web | kens, chrisl: Are you here yet? | 00:42.48 |
| | Aha, evidently. | 00:43.30 |
| chrisl | robin_web: yeh, got in an hour ago or so | 00:43.56 |
| robin_web | Well, come on down! :) | 00:44.23 |
| | You guys up or foodlater? | 00:44.36 |
| | or up for food later, even. | 00:44.49 |
| kens | Food is definitely on my agenda | 00:44.54 |
| | Let me know where/when | 00:45.34 |
| robin_web_ | stupid timeout. | 00:47.37 |
| kens | I wondered where you went... | 00:47.47 |
| | Seem to be a lot of Robins around today :-) | 00:48.04 |
| robin_web_ | There is (or was) good swag to be had at the show. | 00:48.52 |
| kens | Umm, any examples ? | 00:49.31 |
| robin_web_ | I have a dinky android | 00:50.57 |
| | and an android torch. | 00:51.05 |
| | and car lighter usb charger | 00:51.22 |
| | and t-shirts. | 00:51.27 |
| kens | :-) | 00:51.35 |
| robin_web_ | etc | 00:51.37 |
| sebras | robin_web_: has google santa been visiting you? | 00:51.53 |
| robin_web_ | Miles says he has diet coke for y'all.# | 00:54.36 |
| kens | only drinkns the real stuff | 00:55.36 |
| robin_web_ | there is real stuff. | 00:56.11 |
| kens | Mmmmm caffeine.... | 00:56.39 |
| | Where about are you and is it ok to come along in a T-sirt ? | 00:57.16 |
| | shirt with buttons needss ironing | 00:57.30 |
| robin_web_ | we're in the exhibition hall | 00:58.51 |
| | down by the lobby. | 00:58.56 |
| | tshirts would be overdressed :) | 00:59.06 |
| kens | I'll try and find you | 00:59.28 |
| robin_web | tor8: We're going for food at 7 when the show closes. If you get in, let us know. | 02:29.29 |
| tor8 | the internet isn't very good here... | 14:46.42 |
| chrisl | tor8: strangely, mine is fine - signal strenght is middle-poor, but the speed and reliability have been okay. Might depend on the position of your room | 14:48.32 |
| tor8 | took me ten minutes before I could load a web page... | 14:48.54 |
| chrisl | What network are you on? | 14:49.41 |
| tor8 | says "Hyatt" | 14:50.41 |
| chrisl | I'm on "Regency Club" - which I suspect we're not supposed to use as it didn't demand a user name or password.... | 14:51.26 |
| tor8 | well, that might explain it! | 14:51.46 |
| chrisl | But it's quick enough that I'm listening to a BBC radio show just now | 14:51.59 |
| tor8 | I got a little card at the reception with a name/password combo anyone could guess | 14:52.21 |
| | took me a good 15 minutes last night of fighting timeouts to just enter that password... | 14:52.21 |
| chrisl | I saw Hyatt listed, but the signal strength is *really* low, so I decided to try the other reasonable looking option with a open connection | 14:53.43 |
| tor8 | I just see encrypted networks, Hyatt was the only open one :( | 14:54.15 |
| chrisl | I've got three unencrypted ones listed: Hyatt, Regency Club, and xfinity | 14:55.36 |
| tor8 | floor 5 must be bad... | 14:56.45 |
| chrisl | Either that or your foil hat is scattering the wifi signals, as well as the mind reading satellite rays... ;-) | 14:57.58 |
| robin_watts_mac | tor8: 3 patches (I think) on my mupdf repo. | 15:46.05 |
| ajp | hi all, working on a gs script that I seem to having trouble with. I'm using GS's pdfwrite to reduce the size of PDF files but I'm losing ~20% of the image. pastebin: http://pastebin.com/aWQ2WB9v | 17:44.21 |
| | not sure if there is an option for GS that i'm missing or using wrong | 17:44.51 |
| | anyone awake in here? | 17:45.10 |
| sebras | ajp: most of the devs are on a company meeting in .us | 17:49.57 |
| ajp | sebras: oic, any idea when they get out? | 17:50.33 |
| sebras | ajp: no, unfortunately. | 17:50.42 |
| chrisl | ajp: it's diffucult to guess without seeing a concrete example - you could try -dUseCropBox to see if the different bounding box makes a difference | 17:51.04 |
| ajp | it's weird because it works perfectly on some PDF files but no others | 17:52.41 |
| | sometimes it drops entire pages and sometimes just 20% of the page | 17:53.05 |
| | and all the PDFs are coming from the same scanner | 17:53.41 |
| chrisl | Maybe the PDFs are crap, then | 17:54.17 |
| kens | I'm just catching up.... | 17:54.47 |
| ajp | elaborate please? | 17:54.52 |
| kens | What version of Ghostscript is this ? | 17:55.04 |
| | and can we see an example PDF fille ? | 17:55.17 |
| ajp | 9.05 | 17:55.21 |
| chrisl | ajp: crap, as it not conforming to the spec.... Do entire pages go missing, or are they blank? | 17:56.05 |
| ajp | yeah, lemme get you guys an example | 17:56.06 |
| kens | WiFi seems to ber very slow down here in the lobby | 17:56.12 |
| ajp | some blank ppages some missing pages, some missing half the page | 17:56.29 |
| chrisl | kens: is the wifi for the show on yet? | 17:56.31 |
| ajp | it's inconsistent | 17:56.43 |
| kens | Oh, the pastebin is a shell script | 17:56.46 |
| | chrisl, I didn't realise there was a diferent one | 17:57.07 |
| chrisl | Robn mentioned to tor8 there was one for the show which *might* be better than the hotel wifi | 17:57.47 |
| kens | ajp do you mean it doesn't heppen on every file, or it doesn't alays happen even with the same file | 17:58.01 |
| | chrisl there is an anDevCon WiFi | 17:58.27 |
| chrisl | kens: that'll be it, but I can't remember the security settings | 17:58.52 |
| ajp | kens: it seems to do the same thing to every file every time, but some files work fine and others dont | 18:00.05 |
| kens | doesn't seem to be wroking though. | 18:00.21 |
| chrisl | ajp: did you try varying the command line parameters (particularly, leave out the -dQUIET option) | 18:00.37 |
| ajp | lemme try that | 18:00.57 |
| chrisl | If you're trying to debug a problem, telling Ghostscript to not emit certain warnings isn't helpful..... | 18:01.44 |
| kens | ajp I would start by leaving off the PDFSETTINGS and set the options individually | 18:01.47 |
| | But at least if its consistent with a given file there's some chance of looking at the problem | 18:01.58 |
| ajp | kens: yeah, that's what I was thinking | 18:02.23 |
| | trying it with the QUIET command | 18:02.35 |
| | er, without | 18:02.43 |
| kens | :-) | 18:03.00 |
| ajp | did the same thing | 18:03.05 |
| chrisl | any extra info on the backchannel? | 18:03.27 |
| kens | OK can we see a file that fails ? | 18:03.29 |
| ajp | example: https://www.dropbox.com/s/bz412rslxsvezip/Scan_001596-smaller.pdf | 18:03.32 |
| kens | seriously dislikes teh canned PDSETTINGS stuff | 18:03.47 |
| ajp | lemme try if without the PDFSETTINGS | 18:04.14 |
| kens | There will now be a long delay while the damp piece of string here reluctantly lets me view the PDF | 18:04.23 |
| chrisl | ajp: along with not telling GS not to print warnings, it's also help not to pipe the warnings to /dev/null..... | 18:04.24 |
| | ajp: evince only displays an image about half the page for that file | 18:05.07 |
| ajp | evince? | 18:05.25 |
| kens | chrisl you are way ahead of me, still waiting for xdropbox :-( | 18:05.28 |
| | maybe I should go back to my room | 18:05.39 |
| chrisl | ajp: linux/gtk PDF viewer | 18:05.44 |
| ajp | oic | 18:05.49 |
| | so you are seeing what i'm seeing? the image cut off just past halfway down | 18:06.23 |
| chrisl | Yeh | 18:06.32 |
| kens | Adobe Acrobat gives me an error 'insufficient data for an image' and only shows half a page | 18:06.35 |
| | looks like your PDF is just plain broken | 18:06.45 |
| ajp | hmmm, it doesn't work at all with PDFSETTINGS taken out | 18:07.30 |
| chrisl | And Ghostscript *does* emit warnings, so like I said, it is a good idea not to just bin the stdout/stderr messages when debugging a problem. | 18:07.34 |
| ajp | yeah i took the dev/null pipe out | 18:07.55 |
| kens | yes, Ghostscript says invalid xref entry and stream length incorrect | 18:08.11 |
| | FWIW GS actually renders more of teh image than Acrobat does | 18:08.53 |
| ajp | i'm getting this: GPL Ghostscript 9.05 (2012-02-08) | 18:08.56 |

| kens | Hmm, is that the same file ? | 18:09.28 |
| ajp | yeah | 18:09.32 |
| kens | Because the file I got only hass one page, not 3 | 18:09.50 |
| ajp | yeah, the original scan has 3 but the output of gs is 1 | 18:10.08 |
| chrisl | Same here.... | 18:10.10 |
| kens | Is the file you sent teh GS output ? | 18:11.00 |
| | Because I really wanted the *original* | 18:11.32 |
| ajp | oops sry wrong file | 18:11.35 |
| | i can link the original one sec | 18:11.44 |
| | https://www.dropbox.com/s/96zxtzdnqdaf8x3/Scan_001596.pdf | 18:12.28 |
| | thanks guys I really appreciate the help | 18:13.37 |
| kens | the Ghostscript produced PDF file will be incomplete because Ghostscript filed to process teh original file completely | 18:13.45 |
| | 1.8Mb and counting.... | 18:14.11 |

| | GPL Ghostscript 9.05: ERROR -12 closing pdfwrite device. See gs/psi/ierrors.h for code explanation. | 18:15.42 |
| chrisl | Seems to work with the current code...... | 18:16.04 |
| kens | That file still only has one page (though at least tis complete) | 18:16.18 |
| ajp | yeah sorry the 3 page file was a different one, got confused | 18:16.34 |
| | this one is only 1 page | 18:16.42 |
| chrisl | And the installed 9.05 on Ubuntu runs without error...... | 18:17.14 |
| ajp | is the error with my machine specifically? | 18:17.17 |
| kens | I'm with chrisl the current code works, best advice upgrade to 9.06 | 18:17.21 |
| chrisl | ajp: what OS are you running? | 18:17.33 |
| kens | If that doesn't work, get the master source and build it | 18:17.36 |
| ajp | ubuntu 10.04 server | 18:17.42 |
| chrisl | Hmmm, I thought 10.04 would be too old for Ghostscript 9.05 to be in the repo | 18:18.39 |
| ajp | i cant remember which guide i used to install it | 18:19.14 |
| | but my repo says its the latest version @ 9.05 | 18:19.36 |
| kens | probably that's the latest package, the current version is 9.06 | 18:20.01 |
| ajp | does it work with 10.04? or is that my problem? | 18:20.21 |
| chrisl | I don't have 10.04 on this machine to try it, but I can't see any reason for it not to - I have used GS on 10.04 before | 18:21.13 |
| ajp | ok, one last question: Should I treat each PDF differently with GS? (like using different commands for each PDF) or can I use a general line just to reduce all of them for my script? | 18:22.32 |
| chrisl | ajp: Ubuntu 10.04 shipped with Ghostscript 8.71 on it... I can only find patches to 8.71 on the Ubuntu updates for 10.04. | 18:23.16 |
| | ajp: generally, all PDFs should work with the same options | 18:23.30 |
| ajp | ok. should i roll back to 8.71? | 18:23.58 |
| chrisl | I think it would be better to get the latest, even if it means building it yourself. | 18:24.41 |
| ajp | OK, thanks kens and chrisl, I really appreciate your time | 18:25.02 |
| | I'm sure I'll be back on monday :D | 18:25.27 |
| chrisl | ajp: just out of interest, I assume you are using non-standard repos to get more up to date packages - do you happen to know what they are? | 18:25.50 |
| ajp | i forget the command to find them | 18:26.08 |
| chrisl | is ashamed to say, he usually uses the gui for it..... | 18:26.52 |
| ajp | lol | 18:26.58 |
| | yeah no GUI here, only pain in the butt | 18:27.11 |
| | have a good dev conference, ttyl | 18:28.13 |
| | peace | 18:28.18 |
| chrisl | The only hassle is that they might be set in several files - otherwise you can fine them with something like "cat /etc/apt/sources.list" | 18:28.19 |
| | ajp: good luck ;-) | 18:28.34 |
| henrys | chrisl:what's the weather like there? | 18:29.12 |
| chrisl | henrys: bright and sunny just now..... | 18:29.42 |
| | henrys: it's pretty nice temperature-wise, but always the risk of rain. | 18:31.24 |
| henrys | yeah just deciding what to pack - heading out of later today | 18:32.20 |
| | my flight gets in too late for dinner so I'll see you tomorrow | 18:33.21 |
| chrisl | Oh, so you're missing Miles's "nice dinner"? That's a shame | 18:33.57 |
| ajp | i updated to 9.06 and all seems to be working fine now! Thanks chrisl and ken | 19:47.25 |
| | kes* | 19:47.31 |
| | kens* | 19:47.35 |
| chrisl | ajp: glad to hear you've had success! | 20:08.39 |
| ajp | now if i can just get my bash scripting right, lol | 20:27.46 |
| firstclassfunc | how does ghostscript compare to other pdf to image converters? | 20:36.25 |
| kens | In what sense ? Speed, qulity, cost, something else ? | 20:36.51 |
| firstclassfunc | quality mostly | 20:38.25 |
| | I've seen many that don't have full support for fonts on both windows and linux | 20:39.16 |
| kens | well ghostscript is pretty full-featured when it comes to fonts, its a mature product and widely used | 20:44.18 |
| | If fonts are not embedded in the document you can add fonts from teh OS, TrueType, type 1, CFF. You can also use TrueType fonts as substitutes for issing type 1 or CIDFonts. | 20:45.12 |
| firstclassfunc | yeah it really is, I can tell. I was curious if you had any experience with other products | 20:51.34 |
| robin_watts_mac | hi ray. Where art though? | 22:43.27 |
| | marcosw_: Miles is looking for you... | 23:05.26 |
| marcosw_ | robin_watts_mac: why? I told him I didn't want to go guitar shopping with him and would be at Starbucks until dinner time. | 23:05.58 |
| robin_watts_mac | ah, ok, if you've spokn to him. | 23:06.14 |
| marcosw_ | sort of, he offered me a key to his room so I could work there but I told him I prefer starbucks since they have latte, but perhaps he misunderstood. | 23:06.55 |
| robin_watts_mac | Well, we're in the middle of the hotel with wifi and power etc, so feel free to join us, should you get caffiened out. | 23:07.38 |
| marcosw_ | miles just called me and we've straightened it out (I think). | 23:08.56 |
| | robin_watts_mac: yes, but no latte! | 23:09.20 |
| | chrisl: I was just sending the links to the latest builds to Gemma and was going to included a mention of -dDisableFAPI but then realized that she only uses Ghostscript, so she shouldn't see any change from 9.06. Or was there another FAPI change that you referred to in your email? | 23:22.13 |
| robin_watts_mac | Hey alexcher. Where are you? | 23:29.09 |
| alexcher0x2 | I'm at the hotel. | 23:29.30 |
| robin_watts_mac | Ken and I are sitting in the middle of the atrium in front of the deli thing, at a table with wifi/power etc. | 23:30.16 |
| | Forward 1 day (to 2012/12/08)>>> | |
