Re: [Qgis-developer] QGIS Crash - Serious problem in 2x
Hi Nyall, thanks for clarification! However I would say that even if using a projected coordinate system (map units m) scalebars are not neccessarily accurate all over the map: if your map covers a small area this may hold true but not if you look at continents. Bernhard Am 25.06.2014 00:13, schrieb Nyall Dawson: On 25 June 2014 01:20, Bernhard Ströbl bernhard.stro...@jena.de wrote: It does also matter in degrees, depending on the projection. same in meters: 1 cm on the map represents always a certain distance in reality (though this distance varies troughout the map depending on the projection and the area covered). If you look at the Lambert map, you realize that the distance between two parallels (10 degrees!) increases towards the pole, although in reality it is always (10*110km =) 1100 km. In the WGS84 map the distance between the parallels is constant but so is the distance between the meridians, but this is false as the distance gets less towards the pole in reality. So a scalebar (in m) being accurate in the middle of the map becomes less accurate towards the edges. Hence my question on which base the scalebar is calculated. The question absolutely makes sense but I don't know the answer :) Could you check? or whom would we have to ask? It's calculated this way: If you're working in a projected coordinate system (ie, map units are metres): - Take the current extent of the map, calculate the width (x max - x min), divide this by the width on paper of the map If you're working in a geographic coordinate system (ie, map units are degrees): - Convert the width of the map (map's extent x max - x min) from degrees to metres, using a variant of the Haversine formula, and treating the current latitude as the MIDDLE LATITUDE from the map's extent - Convert this distance to a scale by dividing by the width on paper of the map So, yes, scalebars using m/km/miles/etc are only an approximation when map units are degrees, and are very inaccurate when used with maps covering a large area or for areas far from the equator.

If that machine also runs QGIS Desktop, you can verify your Qt install has the image plugins by launching QGIS and checking the Providers section in the About QGIS dialog. Since Qt has native, built-in support for PNG, it should always be able to render a WMS request to PNG. If Qt can not load the Qt JPEG image format plugin, then JPEG will not be rendered. Just guessing, but you may try setting the env variable QT_PLUGIN_PATH in the FCGI environment to help Qt find the plugins directory [0].

Re: [Qgis-developer] 2.2 project keeps crashing after load
two useful tricks 1) redirect log to file as stated here http://qgis.org/api/classQgsLogger.html#details export QGIS_DEBUG=level e.g. 3 export QGIS_LOG_FILE=./qgis.log in the shell or add them in the settings-otions-system-environments ... log will be produces using unix EndOFLine so under win you need to convert log file using something like unix2dos executable. 2) attach qgis execution inside VisualStudio and it will stop at the crash... but without debug symbols it's only useful to have an idea of the calling sequence. my 2 cents, Luigi Pirelli (luigi.pire...@faunalia.it - lui...@gmail.com) On 25 June 2014 11:55, Andreas Neumann a.neum...@carto.net wrote: Hi, I have some related questions regarding my crash: * What software are people using to analyze the minidump file? * During the QGIS crash I see that there are 570 messages in the log window - but because QGIS crashes I cannot access these log-messages anymore.

Re: [Qgis-developer] Access count and center point from QgsPointDisplacementRenderer
- using the same renderer (single symbol, categorized, graduated, rule based) for the cluster point Not sure what this means... At the moment you cant use different symbols as center symbol. I like to see this changed and the ability to use categorized or graduated renderer (based on the count, sum/min/max/avg of one group attribute, etc.). Example (i added a screenshot for this): - sample points with nitrat, pH-Value and moisture concentration - show the count of measurements in each cluster vizualized in 3 classes (graduated) (dark green green light green) - show the avg concentration of each value per goup with graduated symbols (the layer could be imported three times and each new information is shifted from the center) I hope its clear now.

Re: [Qgis-developer] 2.2 project keeps crashing after load
Hi, I can only reproduce the issue on Windows (Win7 64bit). It does not appear on Linux 64bit. Also on Windows it does not happen always, but often. I have removed all composers, so this is definitely not a composer issue. I also removed the WMS and it still crashes. It happens with both PostgreSQL and SQLite as a datasource. It does not happen with shapefiles as a datasource. My project is here to download with SpatiaLite 4 as a datasource: http://webgis.uster.ch/temp/qgis_crashing_project.zip If someone on Windows could give it a try. It does not crash always, but often.

I haven't really managed to read anything useful from minidump files yet - I would be happy to learn from others if they can. Andreas, could you experiment with the project file (in 2.2) a bit to track down the source of the problem? E.g.: - will it crash if you remove the WMS layer? - will it crash if you remove composers? I have just tried your project file on Linux/64 and I get no crash (the Postgis layers get removed on load due to missing credentials).

Hi Gino, Thanks for the hints. I will try the thing with the logging. I don't have VisualStudio - will the free express version help? I don't know if the windows nightlies have debug symbols enabled.

Re: [Qgis-developer] 2.2 project keeps crashing after load
For me for the first time, when I double-clicked on the project (qgs file) it opens qgis and immediately crashed (windows 7 64 bit OSGEO latest nightly). I then open the project from within QGIS, it worked fine. And double-clicking on the project also worked subsequently.

Re: [Qgis-developer] 2.2 project keeps crashing after load
Thanks for trying. I just had Jürgen with Teamviewer at my machine and it is quite hard to find out what causes the crashes. It does not crash at every load. Maybe every third or fourth time in average. Turning multit-threading off improves the situation a lot - there are few to none crashes if multi-threading is off. When I have layers with free or horizontal polygon labeling on it crashes more often. So the labeling may trigger the crashes more often but may not be the cause of the crash. I'll keep testing ...

[Qgis-developer] Regression in border stylization in a 2.0.1 project, both in 2.2.0 and in trunk
Hi all, I've opened a bug regarding a regression in border stylization in a 2.0.1 project https://hub.qgis.org/issues/10723 I've attached a small test case to the bug, in order to easily reproduce the problem, and obtained results in 2.0.1, 2.2.0 and trunk. I had several complex project made with 2.0.1 and this bug is a showstopper to adopt a more recent version, since it would be time consuming to redo the stylization. Can someone have a look at it?
