11:33:23 <rulus> Hi, anyone an idea what might go wrong here: http://dump.rulus.be/iMl0mL6OUh.png ? :)
11:38:45 <Ldp__> without knowing what it should look like, hard to say
11:40:43 <rulus> heh, well, the purple is pixelated in some tiles, that shouldn't happen I guess
11:41:07 <Ldp__> which mapnik revision are you using?
11:41:20 <Ldp__> and is this png256?
11:41:38 <rulus> mapnik 0.6.1
11:41:54 <rulus> how do I find out if it's png256? :)
11:41:57 <Ldp__> did it work okay before?
11:42:09 *** jbronn has quit (Ping timeout: 245 seconds)
11:42:35 <rulus> haven't tried it before, so don't know about that
11:42:47 <Ldp__> what do you use to generate the map?
11:42:55 <nikq> Mapnik Trac: Changeset [1683]: added missing file from r1680 and updated CHANGELOG | http://trac.mapnik.org/changeset/1683
11:43:25 <rulus> a slightly modified generate_tiles taken from OSM
11:43:34 <Ldp__> is the purple a PolygonSymbolizer with transparency?
11:43:57 <rulus> yes, with fill-opacity set to 0.25
11:44:13 <Ldp__> there's a line in generate_tiles.py that reads:
11:44:14 <Ldp__> im.save(tile_uri, 'png256')
11:44:14 *** jbronn (~jbronn@70-138-113-15.lightspeed.hstntx.sbcglobal.net) has joined #mapnik
11:44:22 <Ldp__> change that to 'png' and try again
11:45:06 <Ldp__> transparency for 8-bit PNG images was never that good when you already rendered several transparent features on the map
11:45:09 <rulus> hmm, I can't find such a line, but my generate_tile is quite old, maybe I'll get a newer version first :)
11:45:25 <Ldp__> but things have much improved in 0.7.1, with this week's patch adding even better support
11:45:40 <Ldp__> it should be the last line in def render_tile
11:46:14 <Ldp__> line 92 in my version
11:46:27 <rulus> ah, I have view.save(tile_uri,'png')
11:46:47 <Ldp__> oh, ignore what I said about 8-bit PNG, then :/
11:46:52 <Ldp__> you might have found another issue
11:46:54 <rulus> hmm :)
11:47:04 <Ldp__> can you upgrade mapnik?
11:47:18 <rulus> I'll give it a try!
11:47:38 <Ldp__> http://svn.mapnik.org/branches/0.7.1-dev/
11:47:42 <Ldp__> would be the best to try
11:48:28 <Ldp__> did you install 0.6.1 as a package or from source? if from source, 0.7.1-dev should have the same dependencies
11:48:28 *** gavinf has quit (Read error: Connection reset by peer)
11:49:05 <rulus> as a package, but I guess I could just do apt-get build-dep mapnik to install the dependencies
11:49:37 <Ldp__> I'm not versed in apt, but I'll take your word for it
11:50:22 <Ldp__> you need boost 1.34+, libicu (recent version), libfreetype, proj, etc
11:50:25 <Ldp__> full list in http://svn.mapnik.org/branches/0.7.1-dev/INSTALL
11:50:46 <rulus> ok, but will take a while, have to download 60 MB on smallband..
11:50:46 <Ldp__> python scons/scons.py configure
11:50:49 <Ldp__> should point out most
11:50:54 <rulus> okey, thanks :)
11:51:28 <Ldp__> no Telenet unlimited for you yet? :)
11:51:51 <rulus> unfortunately not, but should come soon I hope :)
11:53:34 <Ldp__> Telenet TurboNet, 30Mbps unlimited from July :)
11:55:11 <rulus> I don't know exactly which plan we have here, but it is quite fast, so I guess we'll get unlimited in July indeed
11:56:07 <Ldp__> 30Mbps isn't quite 'smallband' :)
11:59:17 <rulus> right, compiling :)
11:59:33 <Ldp__> don't forget to remove the package before you install from source
11:59:48 <rulus> done that just a minute a go :)
12:00:24 <Ldp__> if it happens in 0.7.1-dev, you might want to ask springmeyer when he wakes up
12:02:35 <rulus> sure, it can't be any wrong xml from my side though? I'm quite new with mapnik (as in: a few days)
12:03:01 <Ldp__> a basic PolygonSymbolizer with opacity shouldn't give that appearance
12:03:15 <rulus> hehe right
12:03:53 <Ldp__> right, I'm off for a bit. Scoring a 'smoske'... bye
12:04:12 <rulus> smakelijk!
12:04:15 <Ldp__> dank u
12:11:12 <nikq> Mapnik Trac: Ticket #477 (semitransparency support for png256) updated | http://trac.mapnik.org/ticket/477#comment:14
12:33:40 <rulus> Hmm, same problem with svn version. However I do get convert warnings [1] now on some tiles; but strangely they do not seem to be related to the pixelated tiles (I get warnings on 'good' tiles while pixelated ones don't give warnings)
12:33:45 <rulus> 1: convert: Invalid background palette index `tiles/Studiegebied/15/16791/10911.png' @ png.c/PNGWarningHandler/1458.
12:45:20 <rulus> aha, it's the convert call, if I comment that out the problem disappears, and it's a lot faster as well

12:49:36 <albertov> springmeyer, artem: ping?
12:58:15 <artem> albertov: hey
12:59:22 <artem> albertov: looks like there's no python tuple to/from boost tuple convertor - we need to write one
13:00:41 <albertov> Hi artem, ah, yeah, I've read that in the log yesterday... I guess that belongs in boost itself?
13:01:18 <artem> It is on boost.python TODO list but hasn't been implemented yet
13:02:07 <albertov> artem: I see
13:03:31 <albertov> artem; could you take a look at http://trac.mapnik.org/ticket/523 when you have a chance? I'd like to see if it looks ok before (if) committing it
13:05:02 <albertov> artme: it's a little different than the original implementation at the gdalcolors branch, less intrusive :) (thanks to the gdal-overviews changes cherry-picked up by dane from that branch)
13:05:15 *** gavinf (~gavinf@196.211.2.133) has joined #mapnik
13:05:58 <artem> albertov: sure, thanks
13:06:10 <albertov> artme: perhaps the tuple convertor could be implemented in mapnik and after we get it working propose it for boost?
13:06:25 <artem> yes
13:07:15 <albertov> artem: great :) I'll apply the patch to trunk then (after a little cleanup i'm doing right now) and implement the XML de/serializing code...

13:41:58 <rulus> Ldp__: the line in generate_tiles.py that says command = "convert -colors 255 %s %s (tile_uri, tile_uri)"
13:42:22 <rulus> and then call(command, shell=True)
13:42:31 <Ldp__> I thought you updated generate_tiles.xml ? The current version does not have that line
13:43:30 <rulus> Haven't updated it, there was no png256 in there so I thought no update was needed :)
13:44:07 <Ldp__> right, but that convert is part of ImageMagick, and does the same: reduce to 8-bit PNG, and apparently uses a dithering method
13:44:59 <rulus> ah, ok, problem solved :)
13:45:09 <Ldp__> if you want 8-bit png files, I suggest you try im.save(tile_uri, 'png256') in your 0.7.1-devel
13:45:21 <rulus> why would I want that?
13:45:40 <Ldp__> smaller file size
13:46:08 <rulus> ah, well, it's not for online use I'm rendering so it doesn't really matter
13:46:10 <Ldp__> if that is no immediate concern, sticking to 'png' is the safe bet
13:46:20 <rulus> ok, thanks :)

17:33:20 <rweait> But I'm guessing your 20 minutes is way more effective.
17:33:24 <springmeyer> then why are you using Centos?
17:34:24 <rweait> the hardware vendor (this is the crashy box) supports centos.

22:15:25 <cmarqu> http://osm.kyblsoft.cz/3dmapa/?zoom=17&lat=75.72122&lon=14.42603&layers=B - just great
22:16:42 <springmeyer> cmarqu: crazy cool
22:16:47 <springmeyer> where did you find it?
22:17:09 <cmarqu> springmeyer: On http://wiki.openstreetmap.org/wiki/List_of_OSM_based_Services
22:18:02 <cmarqu> The random pattern of the trees is very nice too
22:18:39 <springmeyer> yes. I've actually been playing around with that recently
22:18:47 <springmeyer> will be good to compare
22:25:55 <Komzpa> http://osm.kyblsoft.cz/3dmapa/?zoom=16&lat=75.72359&lon=14.41397&layers=B bad gluing.
22:26:52 <springmeyer> Komzpa: ya, there are also some odd artifacts (maybe jpeg optimization) in the water
22:26:56 <springmeyer> but its still cool!
22:27:16 <Komzpa> yes, of course :)
22:27:29 <Komzpa> interesting what projection they use
22:28:35 <springmeyer> spherical-dizzy ;)
22:32:19 <cmarqu> Just now, someone announced a small program warping downloaded tiles to a perspective (German docs only, http://wiki.openstreetmap.org/wiki/User:Hanekomi/OpenGL-Tilebetrachter)
22:32:44 *** dkb has quit (Quit: Leaving.)
22:33:28 <Komzpa> springmeyer: they also make water mirrorish
22:33:43 <springmeyer> yes
22:34:00 <springmeyer> cmarqu: we need to add map rotation to mapnik...
22:34:40 <cmarqu> Especially since the GOOG has it online...
22:35:02 <springmeyer> yep
22:35:08 <springmeyer> cool that fellow is using OpenGL
22:35:12 <springmeyer> thats another one...
22:35:27 <springmeyer> we need to add OpenGL rendering backend, like cairo or agg
22:42:30 * cmarqu hopes a good GSoC student picks up the print support - numenor had a talk about printing at the FOSSGIS conference (I just read the (German) paper about it)
22:42:45 <springmeyer> cmarqu: oh great.
22:42:58 <springmeyer>  I wonder if I could translate it somehow
22:43:29 <springmeyer> numenor is Holger right?
22:43:37 <cmarqu> Yes, Holger Schoener
22:43:44 <springmeyer> right
22:44:02 <springmeyer> yes, his ruby script deals with scaling min/max scale denominators
22:44:19 <springmeyer> that that is the one thing my patch for map resolution has not addressed (even tested yet)
22:44:56 <cmarqu> Yep. His talk doesn't have many technical details, but he imported SVG into Scribus and modified that he said later on the mailing list
22:45:08 <cmarqu> http://www.fossgis.de/konferenz/2010/events/110.de.html
22:46:07 <cmarqu> He has e.g. a north-up arrow on a rotated map, a scale, logo etc.

22:51:58 <rweait> hmm, installing mapnik2 on Centos:
22:52:00 <rweait> Problem encountered parsing mapnik version, falling back to [0, 8, 0]
22:52:21 <springmeyer> rweait: can you please paste whole terminal output?

22:55:11 <cmarqu> "Mapnik [...] suffers from poor esthetic qualities." - way to make friends :)
22:55:35 <springmeyer> cmarqu: naw, its just academic talk
22:55:43 <rweait> who dares to utter such nonsense?!?!
22:56:00 <cmarqu> rweait: 1st link on http://trac.mapnik.org/wiki/MapnikReferences
22:56:17 <springmeyer> compared to ideal world it is true
22:56:51 <springmeyer> rweait: bummer, no clues there
22:57:03 <springmeyer> rweait: can you paste the 'config.log' ?
22:58:13 *** chad_burt has quit (Quit: Leaving...)
22:58:44 <springmeyer> cmarqu: but watch out for that "strict flexibility" of the openstreetmap project ;)
23:03:24 <rweait> http://weait.com/mapnik2.config.log
23:05:21 <springmeyer> rweait: okay, see problem
23:05:46 <springmeyer> it odd, and should be harmless
23:05:50 <springmeyer> can you check?
23:05:54 <springmeyer> does this file exist?
23:05:59 <rweait> on the phone
23:06:04 <springmeyer> file /usr/lib64/libpq.so
23:06:34 <springmeyer> must not
23:06:36 <springmeyer> likely in...
23:06:49 <cmarqu> I see, my map is just missing the Boltzmann constant.
23:06:50 <springmeyer> file /usr/lib64/pgsql/libpq.so
23:07:09 <springmeyer> cmarqu: seriously, can't you fix that?
23:07:22 <springmeyer> already ;)
23:07:35 <cmarqu> What an oversight, can't believe it
23:13:43 <cmarqu> Oh. I didn't expect the paper to end so abruptly. Maybe he was assassinated by a mapnik developer?
23:14:10 * springmeyer rolls across the floor
23:30:59 <nikq> Mapnik Trac: Ticket #525 (SCons CheckLibWithHeader should not use all libraries but actually target  ...) created | http://trac.mapnik.org/ticket/525
23:31:47 <springmeyer> rweait: ^^ thats the bug you hit, again minor but I've known about it for a while just never seen it rear its ugly head in that way...
23:32:25 <springmeyer> super obscure so no need to read!
23:32:42 <springmeyer> rweait: that didn't hold anything up did it?
23:32:52 *** jctull has quit (Quit: jctull)
23:33:00 <rweait> brb still on phone
23:33:07 <springmeyer> ah, no worries
23:35:55 *** willwhite has quit (Quit: willwhite)
23:45:21 <rweait> back now.  Old friend; haven't talked in ages so we had to clear the queue. ;-)
23:45:48 <rweait> I have /usr/lib64/libpq.so.4.1
23:45:59 <rweait> and others but no plain libpq.so
23:46:26 <rweait> also 4 5 5.2
23:46:44 <rweait> and 4 and 4.1 in /usr/lib
23:50:46 <springmeyer> huh, okay
23:51:03 <springmeyer> thanks for info
23:51:26 <rweait> Do I need to make the ln -s and to which target?
23:52:08 <rweait> or, just svn up ?
23:56:25 <springmeyer> for what?
23:56:55 <rweait> this libpq.so thing?
23:57:08 <rweait> Or should it work anyway.
23:57:10 <springmeyer> rweait: no, I think that error is harmless
23:57:12 <springmeyer> yes
23:57:19 <springmeyer> rweait: by the way it looks like Artem renamed trunk/Mapnik2 python bindings to use 'import mapnik2'
23:57:37 <springmeyer> so the hopes I helped you jump through to install in a different spot
23:57:42 <springmeyer> are now unneeded
23:58:11 <springmeyer> I've not had a chance to check in with him on that move, but it does make it easier to run both versions
23:58:27 <rweait> Cool. I'll remember that when I test.  I'll carry on with my manik2 install
23:58:36 <springmeyer> nice, okay
23:58:41 <rweait> still waiting for a complete plaent load... fingers crossed.
23:58:55 <rweait> Thanks again springmeyer !
23:59:05 <springmeyer> no!
23:59:07 <springmeyer> er
23:59:10 <springmeyer> no problem!
