| tor8 | Robin_Watts: ping? | 09:50.14 |
| Robin_Watts | pong | 10:02.38 |
| tor8 | Robin_Watts: if you look at source/fitz/context.c in fz_set_user_css | 10:11.57 |
| | for some forgotten to me now reason I've added fz_lock calls there | 10:12.11 |
| | but they don't seem to be right | 10:12.16 |
| | the fz_free/fz_strdup calls will take the same lock, and I get warnings about taking and freeing locks already held | 10:12.41 |
| | care to shed any light, or should I just zap those lines? | 10:12.53 |
| Robin_Watts | Let me look. | 10:14.40 |
| | If your intent is to ensure that fz_set_user_css is threadsafe, then the locks there are necessary - we just need to be smarter about it. | 10:16.37 |
| | Do the fz_strdup, then lock/free/assign/unlock. | 10:16.56 |
| | oh, wait, no. cos free locks too. | 10:17.34 |
| tor8 | yeah, so I think I'll just zap it | 10:17.56 |
| | fz_set_aa_level isn't threadsafe either | 10:18.11 |
| Robin_Watts | Yeah, I'd just zap it. | 10:18.17 |
| tor8 | Thanks. | 10:18.22 |
| Robin_Watts | We *could* make it thread safe, but it's unclear to me why you'd ever want to use that from more than 1 thread. | 10:18.57 |
| tor8 | not without forking contexts anyway | 10:19.25 |
| Robin_Watts | and there is still a race condition between setting/using, as the use isn't protected. | 10:20.07 |
| tor8 | yeah. I think I must have been drunk that day :) | 10:20.41 |
| | can't explain it any other way... | 10:21.05 |
| | when are you getting in to chicago tomorrow? | 10:21.45 |
| Robin_Watts | 12:30, iirc. | 10:22.04 |
| | Where are we staying? | 10:22.12 |
| kens | Aloft O'Hare | 10:22.18 |
| | shuttle from the airport, its right nearby | 10:22.29 |
| Robin_Watts | Have we been there before? | 10:22.42 |
| kens | Nope | 10:22.46 |
| | http://www.aloftchicagoohare.com/ | 10:22.56 |
| | There are instructions on findign the shuttle on the web site | 10:23.05 |
| tor8 | My flight gets in a bit later at 17.40 | 10:23.09 |
| kens | Its *inside* | 10:23.09 |
| Robin_Watts | Ah, right. It's hear the hyatt, and gibsons, and dennys. | 10:23.36 |
| chrisl | A loft at O'Hare..... we're going down in the world........ | 10:23.45 |
| tor8 | If I don't get in too late, any plans for dinner tommorow night? | 10:24.17 |
| Robin_Watts | tor8: None that have been formalised. | 10:24.31 |
| kens | Over the road seems to be where the restaurants are | 10:24.42 |
| Robin_Watts | I have to get up at 4:30am, so I suspect I'll be flagging quite early. | 10:25.03 |
| kens | 5:30 for me | 10:25.21 |
| chrisl | Hmm, early start tomorrow - better not leave packing until the morning! | 10:25.24 |
| kens | is packing now | 10:25.32 |
| Robin_Watts | yeah, I'm spinning the windows update roulette wheel now, and then I have to pack. | 10:25.47 |
| tor8 | gloats. 15.40 afternoon flight :) | 10:26.03 |
| kens | :http://www.aloftchicagoohare.com/-P | 10:26.12 |
| | :-P | 10:26.16 |
| tor8 | won't be quite as happy on the way back... 22.05 flight back home. | 10:26.38 |
| kens | 17:55 for us | 10:27.45 |
| chrisl | I *really* must get round to replacing my printer...... | 10:34.19 |
| Robin_Watts | Wed/Thurs/Fri in Chicago is sounding hot (28 degrees) | 11:03.07 |
| kens | Yes, I checked | 11:03.17 |
| Robin_Watts | Sat/Sun 21 degrees and raining on the saturday. | 11:03.18 |
| kens | Thursday also has thunderstorms | 11:03.26 |
| Robin_Watts | I'll be wearing shorts to the metings I think. | 11:05.23 |
| kens | And turning down the aircon ? | 11:05.38 |
| Robin_Watts | It is never too cold in meeting rooms. | 11:08.18 |
| kens | I'm pretty sure we've had people complain before | 11:08.36 |
| Robin_Watts | yeah I'm always on the 'too hot' side of the argument. | 11:08.52 |
| kens | :-D | 11:09.01 |
| Robin_Watts | and I can always change into jeans if required. | 11:09.10 |
| chrisl | On the ball as always: Virgin just mailed to tell me I can check-in.... for the flight for which I printed my boarding pass an hour ago! | 11:12.20 |
| kens | Yeah I hd that too | 11:12.29 |
| NTQ | Hi. I have a question about creating a PDF/A-1b from a normal PDF. If my input contains a page with text and an image, ghostscript convertes that whole page to an image. How can I control that behaviour? | 11:29.28 |
| chrisl | NTQ: that means the page contains PDF transparency operations, which aren't support in PDF/A-1b. In short, you can't change that behaviour and get an accurate representation of the input | 11:32.46 |
| NTQ | chrisl: So is this a limitation of the PDF/A-1b standard or from ghostscript itself? | 11:33.48 |
| Robin_Watts | PDF/A-1b mandates no transparency. | 11:34.19 |
| NTQ | Does that mean that normal images without transparency would work? | 11:35.09 |
| chrisl | Yes | 11:35.27 |
| Robin_Watts | If you want file that has transparency converted to a PDF/A-1b file, then either we need to drop information (which is bad), or we need to pre-render it, so that it looks correct. We choose the later. | 11:35.31 |
| kens | FWIW you could instead convert to PDF/A-2 | 11:52.51 |
| NTQ | PDF/A-1b is required. I just found out that the image in my input pdf is in fact a SVG which in turn consists of a rasterized image and an overlayed text. That rasterized image has an alpha channel. | 11:57.05 |
| kens | So, transparency, there you are then. | 11:57.26 |
| NTQ | :) | 11:57.52 |
| | Do you have an idea how I could replace the transparent layer of the image with white? | 11:59.29 |
| | I am not the person who creates the input PDFs, hence I have no control about inserting the correct image format. | 12:01.14 |
| kens | convert the image to something other than SVG (it can't be svg in the PDF anyway). Try TIFF | 12:03.17 |
| | Once the PDF has been created, it would be difficult to remove the transparency | 12:03.45 |
| NTQ | When I create the PDF/A-1b with Adobe Acrobat it creates an image without transparency and lets the text untouched. So it seems Acrobat drops information. | 12:15.40 |
| | Why is ghostscript rendering the background completely blueish in the case there was a transparent image in the source? Does it depend on the ICC-Profile? | 13:35.53 |
| kens | Hw on Earth should we know ? YOu have supplied no context whatever | 13:36.23 |
| | http://www.aloftchicagoohare.com/As always, if you thnkyou have found a bug, then please open a bug report | 13:37.19 |
| NTQ | Before I collect all data to reproduce the issue I thought you could know a similar problem already. | 13:37.45 |
| kens | That's pretty much equivalent to saying 'something is wrong, what could it be?' | 13:38.18 |
| | There are far too many possible causes to even venture to guess, especially without seeing the relevant file. | 13:38.48 |
| | Its almost impossible to discuss PDF 'issues' sensibly wihtout seeing the file. So if you have a problem, report a bug, then we can see it | 13:39.17 |
| NTQ | No problem. | 13:39.35 |
| chrisl | Hmm, seems we are expected to do Postscript support now :-( | 14:54.32 |
| kens | ? | 14:54.38 |
| chrisl | Most recent support mail | 14:54.46 |
| kens | Ah had closed mail client | 14:54.59 |
| | Good grief.... | 14:55.14 |
| | I have no idea how to begin to answer that one, I think I'll ignore it...... | 14:57.05 |
| chrisl | I've got a few ideas how to answer it - none of them diplomatic | 14:58.08 |
| kens | And a customer who *still* hasn't grasped that you can't do rasterops in PDF | 15:04.22 |
| chrisl | rayjj: ping | 15:12.41 |
| tor8 | chrisl: rayjj: the mujs.com domain looks like it has expired | 15:28.45 |
| chrisl | tor8: I get a connection reset error..... that's not what I'd expect, but could wrong | 15:29.41 |
| tor8 | I got the usual DNS is available parking page crap | 15:30.03 |
| | and whois says it expired 4 days ago | 15:30.08 |
| chrisl | Yeh, that's what I'd expect. Maybe my dns is out of date | 15:30.44 |
| rayjj | tor8: chrisl: that's not good. I wonder why I didn't get a reminder on it (I usually do). Let me check it out. | 16:00.15 |
| kens | Right, off now, see you all tomorrow | 16:23.44 |
| rayjj | TWIMC: mujs.com is renewed for 3 years, and seems to work for me. Can anyone else please try it ? | 19:00.37 |
| Robin_Watts | Works for me. | 19:04.56 |
| rayjj | Robin_Watts: Ta | 19:24.41 |
| | Robin_Watts: when are you going to Chicago? (or are you already there)? | 19:25.40 |
| Robin_Watts | tomorrow morning at some ungodly hour. | 19:25.54 |
| rayjj | Robin_Watts: See you the Chi-town, then | 19:26.13 |
| Robin_Watts | thanks. | 19:26.29 |
| rayjj | I get in about 7:20 pm | 19:26.47 |
| Robin_Watts | We get in at 12:30 | 19:28.40 |
| | Tor is much later than us. | 19:28.50 |
