Re: [Qgis-developer] QGis Dufour crashes when using QgsMarkerLineSymbolLayerV2.setSubSymbol()
Hi Alain, Please do file a report. Before you do: Can you try to keep reference to the symbol you are adding ( self.mySymbol = createSymbol() | xxx.setSubSymbol(self.mySymbol) ) and see if that fixes your problem. Please file a bug even if it does fix it so we can still consider passing ownership to C++ in that bugreport.

And if we display just the group symbol (without individual grouped markers), there is the clustered marker renderer, isn't it? :-) From the technical point of view it is the same thing and the difference is I think mainly in the use: point displacement is meant for few close points (e.g. within a distance of 5 meters), while marker cluster would be used for lots of points (and the distance is best entered in pixels rather than map units to keep the map readable with any scale).

Re: [Qgis-developer] On the fly simplication of point layers
Hi, Thanks for explaining this. I think it would be very cool to have such clustering available in QGIS. From time to time the questions comes up - and other GIS have this available (e.g. OpenLayers, UMN - see http://mapserver.org/mapfile/cluster.html) Around 10-12 years ago. I did a clustering webmap-app with Postgis and SVG. The use case was for a geology company who has around 20k reports in all of Switzerland - although with a focus on the german part of Switzerland. For small map scales we wanted to display clustered symbols, as we zoom in we wanted to display single points eventually at a large scale. In between we had threshold values of different cluster sizes. But I agree with you that a notion of pixels would be better than fixed map units for that purpose. In our webmap-app we had differents symbols for clusters (red, bigger squares) vs. single points where no clustering was made because (blue smaller rectangles). The clustered symbols also varied in size based on the number of features the cluster contains - see http://www.carto.net/neumann/temp/bis_berichte.jpg as an example and http://www.carto.net/neumann/temp/berichte.jpg for a zoomed in view. I think however, from the usage, UI and preferences point of view the options for the point displacement renderer are quite different from the point clustering. For the clustering you want to be able to have different sizes and shapes for clustered vs. single point symbols. You want to be able to label the cluster symbol with the number of features it contains. You want to be able to vary/classify the point symbol based on the nr of features the cluster contains. For the identify tool it would still be good to see the whole list of the cluster. Would be interesting to see if someone could work on this and if someone could fund the work. We would certainly be interested in the feature but have other priorities for our funding.

[Qgis-developer] Blend modes and vector printing
Hi, I know that one has to print in raster if one uses blend modes. I love blend modes but I tend to avoid them because one has to print in raster. My question is: is it a limitation of the qt PDF export? As far as I know Adobe PDF supports blend modes. Could the PDF exporter of qt be improved? As far as I know it should now be a bit easier to contribute to qt. Would it be an option to develop improvements in qt's PDF renderer? A similar situation is with qt and SVG. It is sort of imported but some features are lacking and the exported SVG structure is not optimized.

Re: [Qgis-developer] save as spatialite very resource consuming
Hello all I've noticed recently (QGIS 2.0.1, Windows 7 64 bit), that, when I'm processing a shapefile as layer, even very small ones, the operation 'save as spatialite' takes forever. With a small shapefile (1 KB), the process of converting takes up to 3 minutes, the generated spatiallite is then always around 4000 bigger (4.21 MB). These ratios are the same, no matter how big the file is, the time taken enlarges linearly it seems. When the export is a shapefile again, the whole thing is a matter of seconds. Is this due to some kind of buffering issues or does this conversetion simply take that many resources?

[Qgis-developer] QGIS and 3D

[Qgis-developer] Print composer and constrained line elements
Hi, I know it is already feature freeze - but what I am still missing in the print composer - is the ability to constrain a line to be horizontal or vertical. In Inkscape you do this with the ctrl-key, which limits it to 15 or 30 degree steps. In QGIS we have something similar with the point rotation which you can restrict to these steps. And maybe the arrow should be renamed to line and the arrowhead should be an option, not the default. I often need lines in my layouts, but not so often arrows. What do you think? I could also wait for QGIS 2.4 of course ... I will be patient. Andreas ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] QGIS and 3D
Hello Giuliano, As for now, there is no support for 3D in QGIS, be it for visualization, or internally. If you want to have some 3D features for your GIS you can : * use qgis2threejs to visualize layers on top of a MNT with a WebGL browser * Use the 3D features of grass through QGIS * Use latest PostGIS versions, which allow you to manipulate 3D objects. PostGIS + SFCGAL lets you do some computations on 3D objects with SQL. You can send SQL commands from within QGIS. See this video for an example and visualization of 3D objects with Horao (QGIS plugin to view PostGIS 3D objects) : http://vimeo.com/74869530 There will probably be at some point an effort to support 3D objects in the low level QGIS code, and Marco already worked a bit on it I think. But this is a heavy-lifting task and a lot more work and funding are needed. Maybe Marco can elaborate a bit more on this.

Then hopefully people 1) can check if these PR's are still mergeable (I can do that) 2) have some guidance in the 'importance' of the PR's and we can have some 'focus' 3) we can ask a core dev to have a look into the code and decide if the fix is ok (or not!). Idea? I'm late to make suggestions for features, but here following a small list of (hopefully) issue fixing PRs https://github.com/qgis/QGIS/pull/1071 this fix area calculations when OTFR in on (regardless of a layer is reprojected or not). This is really hurting right now in qgis 2. https://github.com/qgis/QGIS/pull/1037 this should fix the value map widget, also broken in qgis 2 https://github.com/qgis/QGIS/pull/772 this PR claims to solve memory leaks in symbology, but is unclear to me if it is a finished job or not. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

It is probably unrelated, but I've found a similar problem handling empty values, it seems like in several parts of the core, QString.isEmpty is tested instead of QString.isNull. I mean, at least for request parameters, they should be trated as three-state: (null, empty string and a string with not-zero length).

[Qgis-developer] qgis 2.2: removing spit and disabling avoid intersection of new polygons
Hi all, a while ago I proposed to get rid of SPIT as it is unmaintained and now redundant with a similar tool in the processing toolbox. This will happen for 2.2? More serious is the issue with the avoid intersection option in the snapping dialog: the functionality is broken as it often does not remove all the overlapped parts, leaving behind (very) small areas and creating multipart polygons when it is supposed to not happen. There have been some discussion (and even a fix funding proposal) but afaik no work has been done. As this tool does not work as advertised and creates a lot of issues when digitizing maps than need to be topologically correct, then I propose to disable it until fixed (and this is a pity, as is one of the most powerful options in qgis regarding dizigiting).

On 24/01/2014 11:39 pm, Andreas Neumann a.neum...@carto.net wrote: Hi, I know it is already feature freeze - but what I am still missing in the print composer - is the ability to constrain a line to be horizontal or vertical. In Inkscape you do this with the ctrl-key, which limits it to 15 or 30 degree steps. In QGIS we have something similar with the point rotation which you can restrict to these steps. And maybe the arrow should be renamed to line and the arrowhead should be an option, not the default. I often need lines in my layouts, but not so often arrows. What do you think? I could also wait for QGIS 2.4 of course ... I will be patient. This is something on my to-do list. I think there's also considerable scope for improving how lines can be interacted with (eg, being able to drag the start and end points rather then using a bounding box to resize). It'd be nice to have the ability to curve lines too. It'll have to wait to 2.4 though! I'd appreciate it if you could file requests for any missing line functionality that you think of.
